This document specifies electric safety requirements for protection against electric shock and thermal incidents of electric propulsion systems and conductively connected auxiliary electric systems of-electrically propelled mopeds and motorcycles when used in normal conditions. It is applicable to a maximum working voltage of the on-board electrical circuit up to 1 000 V alternating current (a.c.) or 1 500 V direct current (d.c.). This document does not provide comprehensive safety information for manufacturing, maintenance and repair personnel. NOTE Requirements for conductive connections of electrically propelled mopeds and motorcycles to an external electric power supply are described in ISO 18246.
