9.6 Electrical Connection
All electrical connections and wiring must comply with normally-
accepted 12 VDC wiring practices, local regulations and
ABYC/RVIA standards. Only a qualified electrical installer should
complete the wiring. All field wiring is to be in accordance with
CSA Standard C22.1, Canadian Electrical Code Part l or the
National Electrical Code, ANSI/NFPA 70.
WARNING
12 VDC
• Primary DC power to the module should originate after the
master disconnect switch from a dedicated connection on the
house battery bank.
• The power connection to the module from the power supply
is through the Distribution Module Zone Control Board itself.
A 25 amp fuse or breaker must be included inline from the
power source to the positive connection on the zone board.
The primary power wire gauge must be sized to permit no
more than a 3% voltage drop from the power supply to the
zone board. There are no direct 12 VDC power connections
onto the Distribution Module itself. Refer to Figure 9-9:
Distribution Module Wiring.
