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 similar sites. This part of 61439 defines the specific requirements of ACS as follows: ?C 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.; ?C ASSEMBLIES where the nominal primary voltage and the nominal secondary voltage of transformers incorporated in ACS are within the limits specified above; ?CASSEMBLIES 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 (buildings) or civil engineering (public works) or excavation or any other similar operations are carried out; ?C 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 individual 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 rooms@ 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.
