This document specifies safety requirements for miscellaneous electronic circuits used with luminaires for use on DC supplies up to 1 500 V or on AC supplies up to 1 000 V at 50 Hz or 60 Hz. Miscellaneous electronic circuits used with luminaires covered by this document are control circuits of electronic controlgear (e. g. as specified in IEC 62386 series, IEC 63128 or IEC 62756); switching circuits used in association with daylight and/or presence sensors; circuits to assist EMC performance; intermittence and similar devices used with lighting chains; earth leakage or open-circuit protective devices used with neon transformers. This document does not apply to other circuits or devices for which specific IEC standards are published, such as the IEC 60669 series. Note: Such miscellaneous electronic circuits can also be used in luminaires producing optical radiation other than visible spectrum.
