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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 third edition cancels and replaces the second edition published in 2002,
Amendment 1:2006 and Amendment 2:2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• the text has been aligned with Edition 5.2 of Part 1;
• additional requirements for security fence energizers have been introduced (Clauses 3, 7,
19, 22, Figures and Annex BB);
• specific requirements for battery operated energizers have been moved to Annex S.

IEC 60335-2-76:2018 © IEC 2018 – 5 –
The text of this International Standard is based on the following documents:
FDIS Report on voting
61H/366/FDIS 61H/367/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60335 series, published under the general title Household and
similar electrical appliances – Safety, can be found on the IEC website.
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 fifth edition (2010) 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.
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.
NOTE 4 The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation
nationally not earlier than 12 months or later than 36 months from the date of publication.
The following differences exist in the countries indicated below:
6.101: Only energy limited energizers are allowed (All EU and EFTA counties).

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.
NOTE 1 Throughout this publication, when “Part 1” is mentioned, it refers to IEC 60335-1.
When a part 2 standard does not include additional requirements to cover hazards dealt with
in Part 1, Part 1 applies.
NOTE 2 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 3 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.

Note 3 to entry: An impulse signal from an adjacent electric security fence powered by an independent
security energizer not belonging to the same security energizer fence system is not an example of a possible
impulse timing signal source.
3.8 Definitions relating to miscellaneous matters
3.8.101
standard load
load consisting of a non-inductive resistor of 500 Ω ± 2,5 Ω and a variable resistor that is
adjusted so as to maximize the energy per impulse or output current in the 500 Ω resistor,
as applicable
Note 1 to entry: The variable resistor is connected in series or parallel with the 500 Ω resistor, whichever gives
the more unfavourable result.
3.8.102
earth electrode
metal structure that is driven into the ground near an energizer and connected electrically to
the output earth terminal of the energizer, and that is independent of other earthing
arrangements
3.8.103
pulsed conductors
conductors that are subjected to high voltage pulses by the energizer
3.8.104
connecting lead
electric conductor, used to connect the energizer to the electric fence or the earth electrode
3.8.105
fence
barrier for animals or for security purposes, comprising one or more conductors, such as
metal wires, rods or rails

3.8.106
electric fence
barrier that includes one or more electric conductors, insulated from earth, to which electric
pulses are applied by an energizer
3.8.107
electric animal fence
electric fence used to contain animals within or exclude animals from a particular area
3.8.108
electric security fence
fence used for security purposes that comprises an electric fence and a physical barrier
electrically isolated from the electric fence
3.8.109
physical barrier
barrier not less than 1,5 m high intended to prevent inadvertent contact with the pulsed
conductors of the electric fence
Note 1 to entry: Physical barriers are typically constructed from vertical sheeting, rigid vertical bars, rigid mesh,
rods or chain-wire mesh.
3.8.110
public access area
any area where persons are protected from inadvertent contact with pulsed conductors by
a physical barrier
3.8.111
secure area
area where a person is not separated from pulsed conductors below 1,5 m by a physical
barrier
3.8.112
security energizer fence system
electric security fence installation where the fences are energized by one or more security
energizers containing one or more security energizer groups that can be type R security
energizer groups or type S security energizers groups
Note 1 to entry: An independent impulse timing signal source used in a security energizer fence system may
be used to set the timing of dependent security energizers in multiple security energizer groups.
4 General requirement
This clause of Part 1 is applicable.
5 General conditions for the tests
This clause of Part 1 is applicable except as follows.
5.2 Modification:
Replace the test specification by the following:
The tests are made on two energizers as delivered, one being subjected to all the tests with
the exception of that of Clause 18, and the other to the tests of 22.108 and Clause 18.
However, the tests of Clauses 22 to 28 may be made on separate samples.

– 14 – IEC 60335-2-76:2018 © IEC 2018
For type A energizers and type C energizers, an additional sample is required for the test of
Clause 18.
Addition:
NOTE 101 Where electronic circuits, electronic components or other devices are normally encapsulated,
specially prepared samples can be used for the tests of 19.11 and 19.101.
5.3 Addition:
The measurements of 22.108 shall be carried out before the tests of Clause 14.
If any electronic component has been damaged during the tests of Clause 14, the tests of
Clause 19 are made twice, once before and once after the damaged electronic components
have been replaced by new electronic components.
5.5 Addition:
The energizer is mounted in a normal position such that the deviation from the position for
which it is designed does not exceed 15°. However, if the energizer is provided with means
for adjustment to the normal position, such as a spirit level, the energizer shall be adjusted to
within ±2° of the normal position.
The earthing terminal of the fence circuit is connected to earth. However, if there is no
indication as to which of the output terminals is to be connected to earth, the terminal that
gives the most unfavourable result is earthed.
5.8.1 Addition:
For type A energizers, type B energizers, type C energizers and type D energizers where
the terminals for the connection of the battery have no indication of polarity, the more
unfavourable polarity of the voltage source replacing the battery shall be applied.
For mains-operated energizers and battery-operated energizers suitable for connection
to the mains, the reference source impedance of the mains supply shall be 0,4 Ω + j0,25 Ω.
5.101 All energizers are tested as motor-operated appliances.
6 Classification
This clause of Part 1 is applicable except as follows.
6.1 Replacement:
Mains-operated energizers and battery-operated energizers suitable for connection to
the mains shall be class II with respect to protection against electric shock.
Compliance is checked by inspection and by the relevant tests.
6.2 Addition:
Energizers shall be of at least IPX4.
6.101 Energizers are classified as being either energy limited energizers or current
limited energizers.
Compliance is checked by the appropriate tests.
