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 50 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
16 A. This is the only way to ensure that the battery is being
charged even though consumers are being supplied.
