BEP 720-MDO - SPECIFICATIONS; Wires For Standard Connection; Wires For Advanced;Optional Connections

Motorised Battery Switch
Model: 720-MDO (Version 8)
OPERATION AND INSTALLATION INSTRUCTIONS
The 720-MDO Version 8 offers a number of advanced installation options, whereby the motor/circuit board
can be fed from an independent 12V or 24V supply, so the switch contacts are fully isolated and can:
• Stillbeoperatedincasetheswitchedbatteryisat
• Control higher voltage circuits e.g. 32 or 48 volt circuits
• Control negative cables in circuits (e.g. full isolation in metal hulled craft)
• Ensure engine electronics are fully isolated from all loads
• NoteVersion8720-MDO’scanbeidentiedbythe7coreconnectioncablewith3coresterminatedinthe
Wago plug, and 4 cores crimp-terminated
Typical installation is with a
key-operated switch at the helm
station and with the motorised
battery switch installed as close
as practical to the battery bank.
Although any switch may be used
BEP offer the specially developed
80-724-0006-00 key switch
(pictured at right).
Another option is to use BEP’s Wireless Remote
Control. This is similar to a car remote, and
provides access from up to 80m. Working
through a 4 channel relay, the wireless
remote (part number 80-911-0045-00)
canbeconguredtocontrolitemssuch
as motorised battery switches, entry
lights, hatch lifters etc in order to
offer safe, easy entry to your vessel
(pictured at right).
