Commissioning

The automatic charger is operational as soon as it is connect-
ed to the mains supply.
Before disconnecting or interrupting the DC voltage connec-
tions, e. g. the charging cable to the battery, the device needs
to be switched off at the mains. Disconnect the mains plug!
Batteries with short circuits may not be charged. There
is a risk of explosion caused by the generated detonat-
ing gas!
Prerequisites
The battery must have a rated voltage of 12 V and a minimum
capacity of 200 Ah. Batteries below this minimum capacity
will not be adequately charged. Batteries with capacities that
are too high will be charged too slowly.
Charging process
The battery is charged automatically. After any mains power
failures, the main charging process is automatically restarted.
The main charging process is stopped when the battery
voltage has reached 14.4 V. At the end of the aftercharging
phase, the charging process switches to trickle charging at a
constant 13.8 V.
Parallel operation
In parallel operation, the current drawn up by electrical equip-
ment should be less than the maximum charging current of
60 A. This is the only way to ensure that the battery is being
charged even though consumers are being supplied.

Mains supply mode on ferries

The main supply voltage on ferries can be prone to heavy fluc-
tuations. Therefore do not connect the device to this voltage.

Generator mode

Please observe the handling instructions in the manufacturer's
2
operating instructions. The generator must satisfy the 230 V
mains power connection values. Only connect the device to
the generator if this runs stably and disconnect the device
3
from this before you turn it off. The voltage peaks generated in
the start-up and shutdown phases can damage the device.
