This part of IEC 61347 specifies particular safety requirements for electronic controlgear for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz and/or d.c. supplies with operating frequencies deviating from the supply frequency, associated with fluorescent induction lamps as specified in IEC 62532 and IEC 62639, for high-frequency operation. For emergency lighting operation particular requirements for controlgear operated from a central supply are given in Annex J of this part. Performance requirements appropriate to the safe operation of emergency lighting are also contained in Annex J. Requirements for emergency lighting controlgear 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 198 reliable emergency operation.
