Operating and loading the auxiliary battery
If the caravan is not connected to the 230 V mains supply, the auxi-
liary battery will supply the electrical system with 12 V DC voltage.
Since the battery only has a limited capacity, the electrical devices
should not be operated for a longer period of time without charging
the battery or connecting the caravan to the 230 V mains connection.
The battery is charged via the battery charger from two possible
input sources:
- 230V mains connection
- generator in the base vehicle
the source of input with the highest input voltage supplies the charge
current for the connected battery.
Battery Sensor
An Intelligent Battery Sensor (IBS) has been connected to the battery
terminal. It monitors the actual current and the actual voltage in a
highly precise manner.
It is possible to precisely predetermine the operating time of the
battery based on the actual consumption. The IBS ensures that the
battery will be changed in good time and assists in providing active
energy management so that the performance requirements of the
different electrical devices can be coordinated 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.
Pushbutton
A pushbutton is located directly on the battery container. It is
j
used to disconnect the battery from the 12 V electrical system. At
the same time, this button serves as a 30 A automatic circuit breaker.
If the caravan is not used for a longer period of time, please discon-
nect the battery from the electrical system in order to prevent the
battery from being excessively discharged.
• Always charge the ancillary battery for at least 10
hours before each journey, directly after each jour-
ney and before you take the trailer temporarily out
of service:
- Before each journey, please check that the battery
is charged (see p. 71). If necessary, connect it to
the mains and press the main switch to start char-
ging the battery.
- The battery is only charged if it has a minimum
voltage of 8V.
- Use every opportunity during your journey to char-
ge the battery.
- Leave the main switch on whenever the trailer is
being used so that the battery is charged regularly.
