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 preserve 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 roof air conditioner at the same time. The
inverter remains active and has voltage in its socket.
As soon as the voltage in supply battery has reached the switch-on point in the
charging current distributor, 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 15).
• B3200
If the charging voltage regulator cuts the connection to the supply battery due
to low voltage, it switches off the inverter at the same time using the MCR9
remote control. There is no voltage in the socket for the inverter.
As soon as the voltage in the supply battery reaches the switch-on point in the
charging current distributor, it restores the connection between the starter and
supply battery and switches the inverter on again using the MCR9 remote
control. There is voltage in the socket again for the inverter.
The air conditioning starts again automatically.
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 15).

Switching off the system
➤ First of all, switch off the air conditioning.
➤ Switch off the inverter using the remote control.
