40、EAR ASSEMBLIES Part 4: Particular requirements for assemblies for construction sites (ACS) 1 Scope NOTE Throughout this standard, the abbreviation 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 simi
41、lar sites. This part of 61439 defines the specific requirements of ACS as follows: ASSEMBLIES for which the rated voltage does not exceed 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
42、 ACS are within the limits specified above; ASSEMBLIES intended for use on construction sites, both indoors and outdoors, i.e. temporary places of work to which the public do not generally have access and where building construction, installation, repairs, alteration or demolition of property (build
43、ings) or civil engineering (public works) or excavation or any other similar operations are carried out; transportable (semi-fixed) or mobile ASSEMBLIES with enclosure. The manufacture and/or assembly may be carried out other than by the original manufacturer. This standard does not apply to individ
44、ual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant product standards. This standard does not apply to ASSEMBLIES for use in the administrative centres of construction sites (offices, cloakrooms, ASSEMBLY ro
45、oms, canteens, restaurants, dormitories, toilets, etc.). Requirements for electrical protection provided by equipment manufactured according 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-
