This part of IEC 61347 specifies particular safety requirements for d.c. supplied electronic ballasts for maintained and non-maintained emergency lighting purposes.
It includes specific requirements for ballasts and control units for luminaires for emergency lighting as specified by IEC 60598-2-22.
DC supplied electronic ballasts for emergency lighting may or may not include batteries.
This standard also includes operational requirements for ballasts which, in the case of other d.c. supplied electronic ballasts, are regarded as performance requirements. This is because
non-operational emergency lighting equipment presents a safety hazard.
NOTE Annex J of IEC 61347-2-3 applies to a.c. supplied ballasts (normal operation) that are also suitable for emergency lighting operation from ac/dc supplies.
