7. Electrical Installations
- If the automatic circuit breaker goes off abruptly again, there is
either a short circuit or an earth fault.
Devices that set off during operation show that there is a
defect; they must be checked and/or repaired by an electrical
engineering specialist.
Switching it back on again and again will do no good. The
automatic circuit breaker also goes off when the rocker
switch is held firmly in place.
Operation when the motor is running
As soon as the motor is running, a relay connects the starter
battery and the motor home battery in parallel. Therefore, the
dynamo charges both batteries. If the vehicle engine is issued,
both batteries are disconnected from each other again. In this
way, the starter battery cannot be discharged by equipment in
the motor home.
Always turn the motor off before hooking up the 230V
mains connection via the CEE external socket.
The 12 V supply for the refrigerator only functions when you
are driving. If the motor has stopped, the 12 V operation of the
refrigerator is automatically turned off again.
To optimally charge a discharged modular battery while
driving, as many 12V electrical devices as possible should
be switched off.
Checklist
• Turn off the motor.
• Switch on the 12 V master switch.
• Turn off all equipment that uses 12 V.
• Start the motor.
The voltage of the motor home battery must rise if
- the engine speed is above the idling speed,
- the vehicle's battery is not completely discharged.
The control panel shows whether or not the generator has been
charged. If this is not the case, please check the following:
• Is the 50A fuse in the supply line to the ancillary battery
near the motor battery functioning properly?
• Is the "Motor running" signal on the input module on?
