Electrical system
Battery charger
The central control panel display
The battery charger is fitted behind a service
cover below the coolbox. Do not attempt to
remove the service cover yourself. Maintenance
work on equipment behind the service cover
must always be carried out at a qualified spe-
cialist workshop.
As soon as the 230 V power supply is connected
and the residual current circuit breaker is
switched on, the battery charger automatically
starts charging. It charges the additional battery
and also supplies the 12 V power supply. When
the battery is fully charged, its charge is main-
tained at an almost constant level.
The central control panel display shows the
charge status of the additional battery as a bar
graph =. The bars flash one after the other dur-
ing the charging process.
If the following conditions are fulfilled, the bat-
tery charger also charges the starter battery of
the vehicle:
the voltage of the starter battery must be
R
between 9.5 V and 13.85 V
the voltage of the additional battery must be
R
at least 13.9 V
i
This is an auxiliary charge (4 A) which com-
pensates for the self-discharging of the bat-
tery and which ensures that the vehicle can be
started. The starter battery is not fully
charged.
