Driving mode: power supply from the 12 V battery with motor
switched on
In driving mode, the starter and supply battery are electrically connected
when the light system is active. This means the supply battery can be
charged from the light system.
Starter batteries may not be discharged as much as supply batteries. To pre-
serve the starter battery, the charging current distributor separates the starter
battery from the supply battery, if the charging voltage in the starter battery
drops below 10.5 V. This also ensures that the starter battery is charged
before the supply battery.
If the charging voltage regulator cuts the connection to the supply battery due
to low voltage, it switches off the compressor in the roof air conditioner at the
same time. The inverter remains active and has voltage in its socket.
As soon as the voltage in the supply battery has reached the switch-on point
in the charging current distributor, the compressor in the roof air conditioner
switches on again.
If the voltage in the supply battery drops further and goes below the 10.5 V
switch-off point for the inverter, the inverter switches off (chapter "Driving
mode: power supply from the 12 V battery with motor switched off" on
page 27).

NOTE
Observe the maintenance and cleaning instructions in the
operating manuals of the individual components.
➤ Check the power supply lines for abrasion or defects regularly.
➤ Have the system checked regularly by a specialist.
➤ If you find any faulty fuses, have the system checked by a specialist.
