Wiring Diagram
Please refer to Figure 1 below for the recommended wiring configuration.
CAUTION – Potential Hazard
If the DC+ and DC- sense wires are at risk of mechanical damage in their installed
location, appropriately rated in-line fusing is highly recommended due to the potential
fault currents available from the connected battery bank.
The EarthGuard is internally fused at 50mA. As such, operational current on DC+ and
DC- will never exceed 50mA even in the event of an internal failure. External in-line
fusing is purely for protection from a short circuit occurring between the DC+/- sense
wiring as high potential fault currents (Fire Hazard) are present.
