This part of IEC 61347 specifies particular safety requirements for electronic control gear for use on a.c. and d.c. supplies up to 1 000 V at 50 Hz or 60 Hz with operating frequencies deviating from the supply frequency@ associated with fluorescent lamps as specified in IEC 60081 and IEC 60901@ and other fluorescent lamps for high-frequency operation. Performance requirements are the subject of IEC 60929. Particular requirements for electronic control gear with means protection against overheating are given in Annex C. For emergency lighting operation@ particular requirements for control gear operated from a central supply are given in Annex J. Performance requirements appropriate to the safe operation of emergency lighting are also contained in Annex J. Requirements for emergency lighting control gear operating from non-centralised power supplies are given in IEC 61347-2-7. NOTE Performance requirements detailed by Annex J are those considered to be safety-related with respect to reliable emergency operation.
