a) Connection to a Voltage/Current Supply
Attention!
Always connect the charger to the voltage/current supply rst; only then must a rechargeable battery be
connected to the charger.
The charger offers two different options for operation:
• Operation via the mains voltage (100 - 240 V/AC, 50/60 Hz)
• Operation via stabilised direct voltage (11 - 18 V/DC, e.g. via an external vehicle lead battery or a mains adapter)
Never use both operating modes at the same time. This may damage the charger. Loss of guarantee/war-
ranty!
The charger has a maximum total charging output of 300 W. If the charger is to be operated via the direct voltage
input, the power supply strength must be chosen depending on how high the actually used charging output is (depend-
ing on the rechargeable battery type, cell number and the charging current set).
When fully using the maximum total charging output of 300 W, the conversion loss increases power intake
by about 20 - 30%.
If the charger is not to be operated at a 12 V vehicle lead battery, but via a xed voltage mains unit, it must
be able to supply a correspondingly high current.
When using the direct current input, observe the correct polarity when connecting (plus/+ and minus/-).
The charger will switch on automatically after connecting to the voltage/current supply. The three displays light up and
the starting message appears. The charger emits a brief signal.
The charger is then ready for operation.
