WARNING!
On first connecting to power, make sure the
ChargeMaster Plus is in a well-ventilated area
as it might spark.
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 or the
chassis.
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.
For a safe installation the correct wire cross section must
be applied. Don’t use a cross section that is smaller than
indicated. See the following table to select the appropriate
