Battery charger
The battery charger (marked “3” in the figure) automatically charges the batteries B1 and B2 when
connected to the 230 V power supply. (See “Establishing the 230 V power supply” and “Charging the living
room battery B2”.)
Circuit breakers B1, B2 and heating
The circuit breakers B1, B2 (marked with “5” and “6” in the figure) can be used to interrupt the current
between starter battery B1/living room battery B2 and the connected consuming units, e.g. to prevent
deep discharge if the vehicle is not used for an extended period of time. A dedicated circuit breaker is
provided for operating the heating (marked with “7” in the figure) so only the heating can be supplied
with power if required. Before the living room battery B2 is disconnected from the circuit, the control
panel for the heating has to be switched off. (Also see “Laying up for winter”.)
Charging the living room battery B2
If the voltage of the living room battery B2 has dropped below the critical value of 10.5 V, it has to be
charged. To do this, establish the connection to the 230 V power supply. (See “Establishing the 230 V
power supply”.) The symbol “control light for battery charging with external cable” now lights up.
