around the cables. The negative cable should be
connected directly to the negative post of the
battery bank or the ground side of a current
shunt. Do not use the chassis frame as the
negative conductor. Tighten securely. The
positive battery cable must be fused and
connected to the positive post of the battery
bank.

WARNING!
The ground wire offers protection
only if the enclosure of the
ChargeMaster Plus is connected
to the safety ground. Connect the
ground terminal (PE / GND) to the
hull, chassis or Distribution
Apparatus.
