30、hout this part, the abbreviation PSC-ASSEMBLY (see 3.1.101) is used for a power switchgear and controlgear ASSEMBLY. This part of IEC 61439 defines the specific requirements of power switchgear and controlgear assemblies (PSC-ASSEMBLIES) as follows: ASSEMBLIES for which the rated voltage does not ex
31、ceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; stationary or movable ASSEMBLIES with or without enclosure; ASSEMBLIES intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment
32、; ASSEMBLIES designed for use under special service conditions, for example in ships and in rail vehicles provided that the other relevant specific requirements are complied with; NOTE 2 Supplementary requirements for ASSEMBLIES in ships are covered by IEC 60092-302. ASSEMBLIES designed for electric
33、al equipment of machines. Supplementary requirements for ASSEMBLIES forming part of a machine are covered by the IEC 60204 series. This standard applies to all ASSEMBLIES whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity. The m
34、anufacture and/or assembly may be carried out other than by the original manufacturer (see 3.10.1). 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 standard
