It does not apply to low-voltage switchgear and controlgear assemblies which are dealt with in IEC 60439.

NOTE – In certain clauses or subclauses of this standard, the equipment covered by this standard is also referred to as ²device², to be consistent with the text of such clauses or subclauses.

The object of this standard is to state those general rules and requirements which are common to low-voltage equipment as defined in 1.1, including for example:

– definitions;

– characteristics;

– information supplied with the equipment;

– normal service, mounting and transport conditions;

– constructional and performance requirements;

– verification of characteristics and performance.

Digital inputs and/or digital outputs contained in switchgear and controlgear, and intended to be compatible with programmable controllers (PLCs) are covered by Annex S.
