WIRE BY WIRE DETAIL

BATTERY COMPARTMENT

The dual shunt is the current sensor for the Link 20. Its 50 mV @ 500 A rating means that when 500 amps flows through it, 50 mV is generated across it. The millivolt signal is translated into an amps display in the meter. For example: A 50 A load generates 5 mV across the shunt and would be displayed as 050 amps. Caution: In the diagram below, the darker wires represent primary wiring and should be able to carry full battery load current. Size appropriately!
