• It is recommended that electrical terminations and connections are
carried out by a marine electrical technician.
• Negative terminations, and Positive terminations must be to the same
numbered studs i.e. both Negatives must be connected to studs num-
bered “1”, or both Negatives connected to studs numbered “2”. Failure
to do this will result in short circuit or fi re!
• These battery switches are for isolation purposes and are not designed
for switching under load. Ensure there are no circuits with high
inductive loads directly connected to the switch in order to prevent any
sudden in-rush of current which may cause damage to the switch.
• Although specially selected chemical resistant materials have been
used, it is recommended that for maximum product life only plastic
safe corrosion inhibiting sprays are used.
• Ensure all cables are sized correctly for the loads they carry - refer to
www.bepmarine.com to calculate correct cable sizes.
• Ensure all electrical connections are correctly tightened to prevent any
damage to the battery switch.

This innovative (patent pending) switch combines the functionality of three battery switches (House,
Start & Emergency Parallel) into one by simultaneously controlling two battery banks and two loads.
In the unlikely case of engine malfunction, a unique safety position isolates one load (e.g. House
ON/Start OFF) so emergency radios call can be made. With improved access for cabling and three
mounting options, the 772-DBC battery switch offers signifi cant savings in space and installation time.
