marinco 772-DBC Installation Instructions

Dual Bank Control Battery Switch
772-DBC 400A Dual Bank Control (Retail Packed)
772-DBC-B (Bulk Packed)
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.

• High temperature reinforced plastics
Specifi cations:
• Continuous rating: 400A*
• Intermittent rating: 600A* (5min)
• Cranking rating: 1500A* (10sec)
• 12-48V DC (Higher voltage applications on request)
• Connection stud size: M10 (3/8")

Installation Instructions: IMPORTANT! Read before installing
• 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

• 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.
