Run the positive and negative cables next to
each other to limit the electromagnetic field
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.

CAUTION!
According to local regulations an
RCD/Breaker (also known as
GFCI) must be placed in the AC
input circuit of the ChargeMaster
Plus.
For Australia and New Zealand, the
wiring rules are in accordance with
AS/NZS 3000.
