23、al 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
24、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
25、 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 Standardi
26、zation (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 repres
27、entation 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
28、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 publica
29、tions. 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,
30、 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
31、 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
32、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 elemen
33、ts 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. International Standard IEC 61439-4 has been prepared by subcommittee 17D: Low-voltage switchgear and controlgear assemblies, of IEC technical committee 17:
34、 Switchgear and controlgear. This first edition of IEC 61439-4 cancels and replaces the second edition of IEC 60439-4 (2004), and constitutes a technical revision. This edition includes the following significant technical changes with respect to the last edition of IEC 60439-4: modification of the t
35、itle as “Part 4: Particular requirements for assemblies for construction sites (ACS)” alignment on IEC 61439-1 regarding the structure and technical content, as applicable; to allow comparison with tested ACS. 4 61439-4 IEC:2012 The text of this standard is based on the following documents: FDIS Rep
36、ort on voting 17D/460/FDIS 17D/469/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This standard is to be read in conjunction w
37、ith IEC 61439-1. The provisions of the general rules dealt with in IEC 61439-1 (hereinafter referred to as Part 1) are only applicable to this standard insofar as they are specifically cited. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be
38、adapted accordingly. Subclauses that are numbered with a 101 (102, 103, etc.) suffix are additional to the same subclause in Part 1. Tables and figures in this Part 4 that are new are numbered starting with 101. New annexes in this Part 4 are lettered AA, BB, etc. In this standard, terms written in
39、small capitals are defined in Clause 3. The readers attention is drawn to the fact that Annex AA lists all of the “in-some-country” clauses on differing practices of a less permanent nature relating to the subject of this standard. A list of all parts of the IEC 61439 series, under the general title
40、 Low-voltage switchgear and controlgear assemblies, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publicat
41、ion. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61439-4 IEC:2012 5 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES Part 4: Particular requirements for assemblies for construction sites (ACS) 1 Scope NOTE Throughout this standard, the ab
42、breviation ACS (ASSEMBLY for construction site, see 3.1.101) is used for a low-voltage switchgear and controlgear assembly intended for use on construction and similar sites. This part of 61439 defines the specific requirements of ACS as follows: ASSEMBLIES for which the rated voltage does not excee
43、d 1 000 V in case of a.c. or 1 500 V in case of d.c.; ASSEMBLIES where the nominal primary voltage and the nominal secondary voltage of transformers incorporated in ACS are within the limits specified above; ASSEMBLIES intended for use on construction sites, both indoors and outdoors, i.e. temporary
44、 places of work to which the public do not generally have access and where building construction, installation, repairs, alteration or demolition of property (buildings) or civil engineering (public works) or excavation or any other similar operations are carried out; transportable (semi-fixed) or m
45、obile ASSEMBLIES with enclosure. The manufacture and/or assembly may be carried out other than by the original manufacturer. This standard does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the
46、relevant product standards. This standard does not apply to ASSEMBLIES for use in the administrative centres of construction sites (offices, cloakrooms, ASSEMBLY rooms, canteens, restaurants, dormitories, toilets, etc.). Requirements for electrical protection provided by equipment manufactured accor
47、ding to this International Standard are given in IEC 60364-7-704. 2 Normative references This clause of Part 1 is applicable except as follows: Addition: IEC 60068-2-27:2008, Environmental testing Part 2-27: Tests Test Ea and guidance: Shock IEC 60068-2-42:2003, Environmental testing Part 2-42: Test
