Due to the increased load requirements and large increases in the cost of copper battery cable, the MD range of battery switches allows you to install the battery switch very close to the battery, reducing cable lengths to the starter motor. They are also ideal for remote isolation of bow thrusters. The 720-MDO has been enhanced to include internal optical sensors providing even more operational functionality to this innovative master switch. Remote operation Battery switch can be mounted alongside battery, reducing cable lengths and cable sizes to starter motor. (Large cost saving in copper cables) Reduced installation labour, due to shorter battery cable runs Manual override option to meet CE requirements Power Draw: Switch off: 12mA. Switch on: 15mA, switch operating 120mA for 3 seconds @ 12V nominal LED status identification for remote control switch Same capacities/specifications and mounting options as standard BEP�Ѣ battery switches Uses same interchangeable 8-91340 labelling system as BEP�Ѣ battery switches Optical sensor benefits (720-MDO only) Can be used to switch in positive or negative lines Low stand by current draw (7mA) (zero if aux control switch used, see instruction sheet) Main contacts isolated from control circuit allowing operation via another battery source
