5 OPERATING INSTRUCTIONS
5.1 Introduction
The Mastervolt ChargeMaster Plus is a fully
automatic battery charger. This means that
under normal circumstances it can be left
switched on with AC power and batteries
connected. The ChargeMaster Plus is suitable
for charging of Li-ion and lead-acid batteries,
which may include maintenance-free, low
maintenance, AGM, gel or deep-cycle batteries.
It operates on both 240V and 120V.
WARNING!
The MLI charging voltages on this
charger fit the Mastervolt Li-ion
(MLI) batteries but do not necessa-
rily fit other Li-ion batteries! Always
follow the instructions provided by
the battery manufacturer!
5.2 Switching on / off
The ChargeMaster Plus is activated by keeping
the ON/OFF button pressed for approximately 3
seconds. The MODE LED will illuminate green. If
necessary and if AC power is available, the
ChargeMaster Plus will start to charge the
batteries.
Note: Once switched on, the ChargeMaster Plus
automatically resumes operation after it
was disconnected from an AC source
temporarily.
By holding the ON/OFF button pressed again for
approx. 3 seconds, the ChargeMaster Plus will
switch off: the ChargeMaster Plus stops and the
MODE LED illuminates red. When the
ChargeMaster Plus was switched off, it can only
be activated by pressing the ON/OFF button
again.
WARNING!
Switching the ChargeMaster Plus off
or “stand-by” does not cut off the
connection to the batteries or the AC
source. This means that voltages are
still present inside the apparatus.
5.3 Status display
The status display at the front side of the
ChargeMaster Plus enables you to control the
charger and monitor the charging process.
Note: The ChargeMaster Plus can also be
monitored from a remote panel like the
Touch 5 (in a CZone network) or the
EasyView 5 (in a MasterBus network). See
section 4.2 for details.
