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.

59 INTRODUCTION
60 It has been assumed in the drafting of this International Standard that the execution of its
61 provisions is entrusted to appropriately qualified and experienced persons.
62 This standard recognizes the internationally accepted level of protection against hazards such
63 as electrical, mechanical, thermal, fire and radiation of appliances when operated as in
64 normal use taking into account the manufacturer's instructions. It also covers abnormal
65 situations that can be expected in practice and takes into account the way in which
66 electromagnetic phenomena can affect the safe operation of appliances.
67 This standard takes into account the requirements of IEC 60364 as far as possible so that
68 there is compatibility with the wiring rules when the appliance is connected to the supply
69 mains. However, national wiring rules may differ.
70 If an appliance within the scope of this standard also incorporates functions that are covered
71 by another part 2 of IEC 60335, the relevant part 2 is applied to each function separately, as
72 far as is reasonable. If applicable, the influence of one function on the other is taken into
73 account.
74 NOTE 1 Throughout this publication, when “Part 1” is mentioned, it refers to IEC 60335-1.
75 When a part 2 standard does not include additional requirements to cover hazards dealt with
76 in Part 1, Part 1 applies.
77 NOTE 2 This means that the technical committees responsible for the part 2 standards have determined that it is
78 not necessary to specify particular requirements for the appliance in question over and above the general
79 requirements.
80 This standard is a product family standard dealing with the safety of appliances and takes
81 precedence over horizontal and generic standards covering the same subject.
82 NOTE 3 Horizontal and generic standards covering a hazard are not applicable since they have been taken into
83 consideration when developing the general and particular requirements for the IEC 60335 series of standards. For
84 example, in the case of temperature requirements for surfaces on many appliances, generic standards, such as
85 ISO 13732-1 for hot surfaces, are not applicable in addition to Part 1 or part 2 standards.

105 – the playing with appliances by young children.
106 NOTE 102 Attention is drawn to the fact that
107 – for appliances intended to be used on board ships or aircraft, additional requirements may be necessary;
108 – in many countries additional requirements are specified by the national health authorities, the national
109 authorities responsible for the protection of labour, the national water supply authorities and similar authorities.
110 NOTE 103 This standard does not apply to
111 – electromagnetically coupled animal trainer collars;
112 – appliances intended to be used in locations where special conditions prevail, such as the presence of a
113 corrosive or explosive atmosphere (dust, vapour or gas);
114 – separate battery chargers (IEC 60335-2-29);
115 – electric fishing machines (IEC 60335-2-86);
