Note: Cable size quoted is one way from battery to device, however suggested cable size is calculated with return run.
1)
Note: If solar panels are wired in Series (increased voltage), then typically 1 x 4mm2 cable run per series string
is suitable.

Based on 10% voltage drop.
Recommended Fuse Protection
From Alternator Battery
50amp Maxi Fuse or Circuit Breaker no greater than 20cm from source
battery.
From Solar Panels
Fusing recommended no greater than 20cm from input to DC2DC
Charger. Typically 15amps per solar panel (consult your panel
specications for further details).

•
On the temperature sensor end, simply connect the ring terminals to the negative terminal
of the main house battery bank.
Optional Remote Display Connection
To install the optional Remote Display in a specic location, a 6 pin standard RJ12 cable
(maximum length 7.5 meters) is required.
