This European Standard was approved by CENELEC on 2003-03-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands,
Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 61D/116/FDIS, future fourth edition of IEC 60335-2-40, prepared by SC 61D of the
IEC Technical Committee 61, was submitted to the IEC-CENELEC parallel vote.
As a result of the Kista meeting of CENELEC TC 61 in May 2002, a draft amendment prAA containing the
relevant existing common modifications was submitted to the formal vote.
The texts of the FDIS and the prAA were approved by CENELEC as a new edition of EN 60335-2-40 on
2003-03-01.
This European Standard replaces EN 60335-2-40:1997 + A1:2000.
The following dates are applicable:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-03-01
- date on which national standards
conflicting with the EN have to be withdrawn (dow) 2007-03-01
This part 2 has to be used in conjunction with EN 60335-1, Household and similar electrical appliances –
Safety – Part 1: General requirements. It was established on the basis of the 2002 edition of that standard.
Amendments and revisions of Part 1 have also to be taken into account and the dates when such
changes become applicable will be stated in the relevant amendment or revision of Part 1.
This part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into the
European Standard: Safety requirements for electrical heat pumps, air-conditioners and dehumidifiers.
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 of
Part 1 is to be adapted accordingly.
NOTE 1 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.;
- subclauses, notes and annexes that are additional to those in the IEC standard are prefixed with the letter Z.
NOTE 2 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 the associated noun
are also in bold.
There are no special national conditions causing a deviation from this European Standard, other than
those listed in Annex ZA to EN 60335-1.
There are no national deviations from this European Standard, other than those listed in Annex ZB to
EN 60335-1.
Annex AA is for information only.

Introduction
p Add:
An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 73/23/EEC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown that
the risks are mainly of electrical origin and consequently this directive is not applicable. However, the
relevant essential safety requirements of the Machinery Directive are covered by this standard together
with the principal objectives of the Low Voltage Directive.

Endorsement notice
The text of the International Standard IEC 60335-2-40:2002 was approved by CENELEC as a European
Standard with agreed common modifications as given below.
COMMON MODIFICATIONS
7 Marking and instructions
p 7.12.1 Add:
The installation instructions for appliances that are intended to be permanently connected to fixed wiring,
and have a leakage current that may exceed 10 mA, shall state that the installation of a residual current
device (RCD) having a rated residual operating current not exceeding 30 mA is advisable.
13 Leakage current and electric strength at operating temperature
p 13.2 Replace "the leakage current shall not exceed" by "the leakage current may exceed 3,5 mA but
shall not exceed”.
15 Moisture resistance
p Replace the first line by:
This clause of Part 1 is applicable except as follows.
p 15.1 Delete this subclause.
p 15.2 Delete this subclause.
p 15.3 Replace the subclause number by:
15.2 Addition:
