Charging contactor function The voltage application contactor for the charging connection and for options is controlled directly via the key switch. The charging contactor closes and applies voltage to the charging switch. The charging switch has a current limit to charge the capacitors in the controllers. The main contactor is only controlled when the capacitors have been charged and the controllers have successfully completed a self-test. All other consumers (e.g. transformer for options, cabin heating) are switched on via the charging contactor.
