7.10 230 V fuse box with an RCD
The 230 V fuse box with RCD protects the 230 V circuit and is therefore fitted with a 25 A fuse. In addition,
an RCD is integrated that interrupts the current flow in the event of leakage currents and short circuits.
CAUTION
Risk of damaging the electrical system!
If the RCD is triggered (interruption of the current flow), the cause has to be identified.
● In this case, contact your authorised dealer or an authorised specialist workshop.
7.11 Circuit breakers B1, B2 and heating
The circuit breakers B1 and B2 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 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 section 13 “Laying up
for winter”.)
7.12 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 item 7.4 “Establishing the
230 V power supply”.) The symbol “indicator light for battery charging with external cable” now lights up.
CAUTION
Risk of deep discharge of the batteries!
If you will not be using the vehicle for an extended period of time, disconnect the power
supply to the 12 V consuming units with the B1, B2 and heating circuit breakers.
Check the state of charge of the batteries regularly using the control panel.
If the voltage of the living room battery B2 drops below the critical value of 10.5 V,
the control panel is switched off automatically. In this case, interrupt the current flow
with the three circuit breakers B1, B2 and heating. Charge the battery within 2 days using
the external 230 V connection and the connected battery charger.
WARNING
Risk of electric shock when replacing the battery!
● Contact with live parts poses a risk of death.
● Have the batteries in your vehicle replaced by an authorised specialist workshop.
