CEI EN 61347-2-7/A2 PDF

This part of IEC 61347 specifies particular safety requirements for electric source for safety services (ESSS) supplied electronic controlgear for maintained and non-maintained emergency lighting purposes.

It includes specific requirements for electronic controlgear and control units for self-contained luminaires for emergency lighting as specified in IEC 60598-2-22.

It is intended for controlgear for fluorescent lamps and other lamp types for example incandescent lamps, high pressure discharge lamps and LEDs.

This document covers the emergency mode operation of a controlgear. For controlgear with a combination of normal and emergency lighting operation, the normal lighting operation aspects are covered by the appropriate Part 2 of the IEC 61347 series.

DC supplied electronic controlgear for emergency lighting can (or not) include the electric source for safety services (ESSS).

This document does not apply to d.c. supplied electronic controlgear for emergency lighting, which are intended for connection to a centralized emergency power supply system. A centralized emergency power system could be a central battery system.

NOTE Annex J of IEC 61347-2-3:2011/AMD1:2016 applies to a.c., a.c./d.c. or d.c. supplied electronic controlgear for connection to centralized emergency power supply systems that are also intended for emergency lighting operations from a.c./d.c. supplies.
