requirements of the different electrical devices can be coordi-
nated with the charging of the battery.
The charge state of the battery, age or remaining time until
discharge are all shown on the TFT display of the control panel.
Charging is carried out gently in accordance with the steady-
state principle by an "intelligent" charger.
The battery sensor is protected by a 10 A .
• Always charge the ancillary battery for at least 24 hours before
each journey, directly after each journey and before you take
the motor home temporarily out of service.
- Before each journey, please check that the battery is
charged (see p. 96). If necessary, connect it to the
mains to start charging the battery.
- The battery is only charged if it has a minimum
voltage of 8 V.
- Use every opportunity during your journey to charge
the battery.
• If the vehicle is not in use for a longer period of time, the batte-
ry should be disconnected after it has been optimally charged
by switching the battery circuit breaker on.
• The battery loses its capacity after having been used
for a while and at low temperatures.
- A warning will go off if the battery ages to a value less
than 50% of its nominal capacity.
• When operating the battery for the first time, the IBS must first
collect measurement data (this process takes approx. 3 hours).
- During this time, the battery's open circuit voltage is
determined.
- A charging/discharge current of < 150 mA is
required to do so.
Battery circuit breaker
Position of the battery circuit breaker
The battery circuit breaker is located directly by the front right
passenger seat.
A circuit breaker has been installed to protect the modular batte-
ry from being exhaustively discharged when the motor home is
not being used. When the switch is opened, the modular battery
is completed disconnected from the 12 V mains.
"Off" position = disconnected from 12V mains.
