The BMS01 is a battery master switch designed for dangerous goods road vehicles complying with international ADR regulations. Environmental protection and the intrinsically safe control circuitry of the BMS01 are in accordance with ADR 2009. The battery switch must be installed between the battery and the vehicle's electrical system. It is operated on and off by means of a control switch in the driver's cab, additional control switches can be sited around the vehicle as required. The BMS01 is a double pole device, but can be connected as 1-pole version (see connection diagram). An integral safety barrier permits siting of the BMS01 in hazardous areas. Additional auxiliary contacts are provided for disconnection of the ignition circuit, de-energisation of the alternator field winding, or a controlled shutdown of the CANBUS system followed after a delay by disconnection of the battery.
