Part 2-76: Particular requirements for electric fence energizers

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International
Organization for Standardization (ISO) in accordance with conditions determined by agreement between the
two organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by subcommittee 61H:
Safety of electrically operated farm appliances, of IEC technical committee 61: Safety of
household and similar electrical appliances.
This second edition cancels and replaces the first edition published in 1997 and its
amendment 1 (1999). It constitutes a technical revision.
The text of this part of IEC 60335 is based on the following documents:

FDIS Report on Voting
61H/173/FDIS 61H/174/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This Part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fourth edition (2001) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60335-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60335-1, so as to
convert that publication into the IEC standard: Safety requirements for electric fence
energizers.
60335-2-76  IEC:2002(E) – 5 –

When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,

the relevant text in Part 1 is to be adapted accordingly.

NOTE 2 The following numbering system is used:

– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;

– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including

those in a replaced clause or subclause;

– additional Annexes are lettered AA, BB, etc.

NOTE 3 The following print types are used:

– requirements: in roman type
– test specifications: in italic type
– notes: in small roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and
associated noun are also in bold.
The committee has decided that the contents of this publication will remain unchanged until
2004. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
The following differences exist in the countries indicated below:
– 6.101: Only energy limited energizers are allowed (Austria, Denmark, France, Germany, Netherlands,
Norway, Switzerland and United Kingdom).
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions. It also covers abnormal

situations that can be expected in practice.

This standard takes into account the requirements of IEC 60364 as far as possible so that

there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

13 Leakage current and electric strength at operating temperature

This clause of Part 1 is applicable except as follows.
13.1 Modification:
Compliance is checked by the tests of 13.2 and 13.3 for mains-operated energizers and
battery-operated energizers suitable for connection to the mains only.
Addition:
The energizer is operated under normal operation when supplied as specified in 11.5 for
mains operation.
14 Transient overvoltages
14.101 Energizers shall be resistant to atmospheric surges entering from the fence.

– 16 – 60335-2-76  IEC:2002(E)

Compliance is checked by the tests of

– 14.102 to 14.104 for mains-operated energizers and types A, B and C energizers;

– 14.102 to 14.104 for type D energizers;

– 14.104 for battery-operated energizers with a rated voltage exceeding 42,4 V.

NOTE The value of U is the peak value of the energizer output voltage obtained during the test of 22.111.
Unless otherwise specified, during the tests, no disruptive discharges shall occur but surge

protection devices are allowed to operate.

Mains-operated energizers and types A, B, C and D energizers are fixed to a metal plate
having dimensions that are at least 150 mm in excess of those of the orthogonal projection of
the energizer on the plate, and are then installed as in normal use.
Battery-operated energizers are installed as in normal use.
The tests are made by means of an impulse generator producing positive and negative full
lightning impulses having a front time of 1,2 µs and a time to half-value of 50 µs, the
tolerances being
• ±5 % for the peak value;
• ±30 % for the front time;
• ±20 % for the time to half-value.
Small oscillations in the impulse are allowed, provided their amplitude near the peak of the
impulse is less than 5 % of the peak value. For oscillations during the first half of the front
time, amplitudes up to 10 % of the peak value are allowed.
The shape of the impulses is adjusted with the energizer connected to the impulse generator.
The adjustment shall be made at approximately 50 % of the test voltage specified. If, for the
test of 14.104, it is not possible to obtain the correct shape of the impulses, it is only
necessary to ascertain that the front time has the required value at approximately 50 % of the
prospective peak voltage specified.
The impulse generator to be used for the tests shall have an energy content of at least 125 J
at the test voltage.
14.102 Five positive and five negative impulses, each having a prospective peak voltage
of 2U but not less than 25 kV, are applied between
– the output terminals and a.c. input terminals connected together and the metal plate, for
mains-operated energizers and types A, B and C energizers,
– the output terminals and the metal plate, for type D energizers,
the interval between consecutive impulses being at least 10 s.
14.103 Five positive and five negative impulses, each having a prospective peak voltage
of 2U but not less than 25 kV, are applied between the output terminals connected together
and
– the a.c. input terminals connected together, for mains-operated energizers and types A,
B and C energizers,
– the terminals for connection of the external battery charger, for type D energizers,
the interval between consecutive impulses being at least 10 s.

60335-2-76  IEC:2002(E) – 17 –

If, during this test, a surge protection device operates, the test is repeated with the surge

protection device rendered inoperative. During the repeat test no disruptive discharges are

allowed.
If the energizer has more than one fence circuit, each fence circuit is subjected to this test

in turn, the other fence circuits being open-circuited.

14.104 Five positive and five negative impulses, each having a prospective peak voltage

of 2U but not less than 25 kV, are applied between the output terminals, the interval between
the impulses being at least 10 s. The input terminals are open-circuited.

15 Moisture resistance
This clause of Part 1 is applicable.
16 Leakage current and electric strength
This clause of Part 1 is applicable except as follows.

16.101 For battery-operated energizers the supply terminals are connected for 10 min to a
voltage between 1,1 and 1,5 times rated voltage for battery supply, that is so chosen that

the output voltage, without a load connected, has the maximum value, protective spark gaps,

if any, being disconnected.
The insulation between the poles of the supply circuit is then subjected for 1 min to a d.c.

voltage of approximately 500 V. Before this test is made, capacitors, resistors, inductors,

transformer windings and electronic components that are connected between the poles of

the supply circuit are disconnected. When a capacitor forms part of an integrated circuit and

cannot be disconnected separately, the circuit as a whole is disconnected.

No breakdown shall occur during the test.

16.102 Immediately after the tests of 16.3 and 16.101, the output characteristics are
measured as specified in 22.108.
The values measured shall be within the limits specified in 22.108 and shall not deviate in an
unfavourable way by more than 10 % from the values measured during the tests of 22.108.
17 Overload protection of transformers and associated circuits
This clause of Part 1 is not applicable.
18 Endurance
Energizers shall be so constructed that they are able to endure extreme temperatures that
may be encountered in normal use. Moreover, overload protection devices shall not operate
under these conditions.
Compliance is checked by the following test.
Mains-operated energizers, and types A and C energizers when they are connected for
mains supply are operated under conditions of normal operation. The voltage applied is the
rated voltage.
Type D energizers, when connected for battery charger supply, are operated under
conditions of normal operation. The voltage applied is as specified in 11.5.
Battery-operated energizers and type B energizers connected for battery operation are
placed in their normal position and are fitted with a battery having a nominal voltage equal to
the rated voltage for battery supply of the energizer. The battery shall be of the largest

type for which the energizer is designed. The battery shall be fully charged at the beginning
of the test and shall be replaced by a fresh one as soon as, during the test, the voltage of the
battery decreases to 0,75 times its nominal voltage for a rechargeable battery or to 0,55 times
its nominal voltage for a non-rechargeable battery.
For types A and D energizers, a battery of the largest type for which the energizer is
designed is connected and placed in the battery compartment. Before starting the test the
battery is discharged to such an extent that the voltage delivered does not exceed 0,75 times
its nominal value.
The other sample, for types A and C energizers, is to be connected for battery supply and
supplied from a battery of the largest type for which the energizer is designed. The battery
shall be fully charged at the beginning of the test, and shall be replaced by a fresh one as
soon as, during the test, the voltage of the battery decreases to 0,75 times its nominal voltage
for a rechargeable battery or to 0,55 times its nominal voltage for a non-rechargeable battery.

Part 2-76: Particular requirements for electric fence energizers

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

This part of International Standard IEC 60335 has been prepared by subcommittee 61H:
Safety of electrically operated farm appliances, of IEC technical committee 61: Safety of
household and similar electrical appliances.
This second edition cancels and replaces the first edition published in 1997 and its
amendment 1 (1999). It constitutes a technical revision.

INTRODUCTION
Il a été considéré en établissant la présente Norme internationale que l'exécution de ses

dispositions était confiée à des personnes expérimentées et ayant une qualification

appropriée.
Cette norme reconnaît le niveau de protection internationalement accepté contre les risques

électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils, lorsqu'ils

fonctionnent comme en usage normal en tenant compte des instructions du fabricant. Elle

couvre également les situations anormales auxquelles on peut s'attendre dans la pratique.

Cette norme tient compte autant que possible des exigences de la CEI 60364, de façon à
rester compatible avec les règles d'installation quand l’appareil est raccordé au réseau
d’alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d’application de cette norme comporte également des
fonctions qui sont couvertes par une autre partie 2 de la CEI 60335, la partie 2
correspondante est appliquée à chaque fonction séparément, dans la limite du raisonnable. Si
cela est applicable, on tient compte de l’influence d’une fonction sur les autres fonctions.
Cette norme est une norme de famille de produits traitant de la sécurité d’appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé
conforme aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais,
il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité
visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.

60335-2-76  IEC:2005 – 11 –
INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions. It also covers abnormal

situations that can be expected in practice.

This standard takes into account the requirements of IEC 60364 as far as possible so that

there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (CEI) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a
pour objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les
domaines de l'électricité et de l'électronique. A cet effet, la CEI – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de la CEI"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec la CEI, participent
également aux travaux. La CEI collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de la CEI
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de la CEI se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de la CEI. Tous les efforts raisonnables sont entrepris afin que la CEI
s'assure de l'exactitude du contenu technique de ses publications; la CEI ne peut pas être tenue responsable
de l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de la CEI s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de la CEI dans leurs publications
nationales et régionales. Toutes divergences entre toutes Publications de la CEI et toutes publications
nationales ou régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) La CEI n’a prévu aucune procédure de marquage valant indication d’approbation et n'engage pas sa
responsabilité pour les équipements déclarés conformes à une de ses Publications.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à la CEI, à ses administrateurs, employés, auxiliaires ou
mandataires, y compris ses experts particuliers et les membres de ses comités d'études et des Comités
nationaux de la CEI, pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre
dommage de quelque nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais
de justice) et les dépenses découlant de la publication ou de l'utilisation de cette Publication de la CEI ou de
toute autre Publication de la CEI, ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’attention est attirée sur le fait que certains des éléments de la présente Publication de la CEI peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour
responsable de ne pas avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.

Part 2-76: Particular requirements for electric fence energizers

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This part of International Standard IEC 60335 has been prepared by subcommittee 61H:
Safety of electrically operated farm appliances, of IEC technical committee 61: Safety of
household and similar electrical appliances.
This consolidated version of IEC 60335-2-76 consists of the second edition (2002)
[documents 61H/173/FDIS and 61H/174/RVD], its amendment 1 (2006) [documents
61H/229/FDIS and 61H/230/RVD], and its corrigendum 1 (August 2013).
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 2.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
The French version of this standard has not been voted upon.

INTRODUCTION
Il a été considéré en établissant la présente Norme internationale que l'exécution de ses

dispositions était confiée à des personnes expérimentées et ayant une qualification

appropriée.
Cette norme reconnaît le niveau de protection internationalement accepté contre les risques

électriques, mécaniques, thermiques, liés au feu et au rayonnement des appareils, lorsqu'ils

fonctionnent comme en usage normal en tenant compte des instructions du fabricant.

Elle couvre également les situations anormales auxquelles on peut s'attendre dans la pratique

et prend en considération les phénomènes électromagnétiques qui peuvent affecter

le fonctionnement en toute sécurité des appareils.
Cette norme tient compte autant que possible des exigences de la CEI 60364, de façon à
rester compatible avec les règles d'installation quand l’appareil est raccordé au réseau
d’alimentation. Cependant, des règles nationales d'installation peuvent être différentes.
Si un appareil compris dans le domaine d’application de cette norme comporte également des
fonctions qui sont couvertes par une autre partie 2 de la CEI 60335, la partie 2
correspondante est appliquée à chaque fonction séparément, dans la limite du raisonnable. Si
cela est applicable, on tient compte de l’influence d’une fonction sur les autres fonctions.
Cette norme est une norme de famille de produits traitant de la sécurité d’appareils et a
préséance sur les normes horizontales et génériques couvrant le même sujet.
Un appareil conforme au texte de la présente norme ne sera pas nécessairement jugé
conforme aux principes de sécurité de la norme si, lorsqu'il est examiné et soumis aux essais,
il apparaît qu'il présente d'autres caractéristiques qui compromettent le niveau de sécurité
visé par ces exigences.
Un appareil utilisant des matériaux ou présentant des modes de construction différents de
ceux décrits dans les exigences de cette norme peut être examiné et essayé en fonction de
l'objectif poursuivi par ces exigences et, s'il est jugé pratiquement équivalent, il peut être
estimé conforme aux principes de sécurité de la norme.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions. It also covers abnormal

situations that can be expected in practice and takes into account the way in which

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

Part 2-76: Particular requirements for electric fence energizers

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

This consolidated version of IEC 60335-2-76 consists of the second edition (2002)
[documents 61H/173/FDIS and 61H/174/RVD], its amendment 1 (2006) [documents
61H/229/FDIS and 61H/230/RVD], its amendment 2 (2013) [documents 61H/287/FDIS and
61H/289/RVD] and its corrigendum 1 (August 2013). It bears the edition number 2.2.

The technical content is therefore identical to the base edition and its amendments and
has been prepared for user convenience. A vertical line in the margin shows where the
base publication has been modified by amendments 1 and 2. Additions and deletions
are displayed in red, with deletions being struck through.

60335-2-76  IEC:2002+A1:2006 – 5 –

+A2:2013
This part of International Standard IEC 60335 has been prepared by subcommittee 61H:
Safety of electrically operated farm appliances, of IEC technical committee 61: Safety of

household and similar electrical appliances.

The French version of the standard has not been voted upon.

This Part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its
amendments. It was established on the basis of the fourth edition (2001) of that standard.

INTRODUCTION
It has been assumed in the drafting of this International Standard that the execution of its

provisions is entrusted to appropriately qualified and experienced persons.

This standard recognizes the internationally accepted level of protection against hazards such

as electrical, mechanical, thermal, fire and radiation of appliances when operated as in

normal use taking into account the manufacturer's instructions. It also covers abnormal

situations that can be expected in practice and takes into account the way in which

electromagnetic phenomena can affect the safe operation of appliances.

This standard takes into account the requirements of IEC 60364 as far as possible so that
there is compatibility with the wiring rules when the appliance is connected to the supply
mains. However, national wiring rules may differ.
If an appliance within the scope of this standard also incorporates functions that are covered
by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
far as is reasonable. If applicable, the influence of one function on the other is taken into
account.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 1 This means that the technical committees responsible for the part 2 standards have determined that it is
not necessary to specify particular requirements for the appliance in question over and above the general
requirements.
This standard is a product family standard dealing with the safety of appliances and takes
precedence over horizontal and generic standards covering the same subject.
NOTE 2 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.
An appliance that complies with the text of this standard will not necessarily be considered to
comply with the safety principles of the standard if, when examined and tested, it is found to
have other features that impair the level of safety covered by these requirements.
An appliance employing materials or having forms of construction differing from those detailed
in the requirements of this standard may be examined and tested according to the intent of
the requirements and, if found to be substantially equivalent, may be considered to comply
with the standard.

authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
NOTE 103 This standard does not apply to
– electromagnetically coupled animal trainer collars;
– appliances intended to be used in locations where special conditions prevail, such as the presence of a
corrosive or explosive atmosphere (dust, vapour or gas);
– separate battery chargers (IEC 60335-2-29);
