Functions
The transformer/rectifier has the following functions:
z
The transformer/rectifier charges the living area battery. The transformer/
rectifier charges the starter battery with a float charge only.
z
The transformer/rectifier monitors the voltage in the living area battery.
z
The transformer/rectifier distributes the current to the 12 V circuits and
secures them. Devices with a maximum of 10 A can be connected to the
sockets.
z
The transformer/rectifier provides connections for a solar charge regulator,
an auxiliary charging unit, as well as other control and monitoring functions.
z
When the engine is turned off, the transformer/rectifier separates the
starter battery electrically from the living area battery. This prevents the
12 V living area appliances from discharging the starter battery.
The transformer/rectifier only works in conjunction with a panel.
The power in the transformer/rectifier (> 18 A) is divided into charging current
and current to the appliances. The charging current is always just the portion
that is not being used by any appliances. If the current to the appliances
exceeds the current available, then the living area battery is discharged.
Position
See chapter 16.
8.5.1
Battery separation
The battery separation switches off
all
12 V appliances in the living area, even
inactive ones. Even appliances such as the entrance step, basic lighting or the
refrigerator will stop working. This prevents the living area battery from slowly
discharging if the vehicle is not used for a longer period of time (e.g. temporary
lay-up).
If the vehicle is connected to the 230 V power supply, the batteries can then
be charged from the transformer/rectifier, even if the battery separation is acti-
vated.
This also applies for charging via a solar installation or fuel cell.
Activating/deactivating
See section 8.8.2
8.5.2
Battery selector switch
Z
Also switch off a refrigerator with automatic power selection system. The
refrigerator will otherwise switch to gas operation.
Z
After deactivation of the battery separation, it may be necessary to reset
the date and time. The remaining settings will be saved at the activation of
the battery separation and will be maintained.
X
If the battery selector switch is set incorrectly, there is the danger of the
formation of detonating (oxy-hydrogen gas). Danger of explosion!
Z
Incorrect setting of the battery selector switch damages the living area bat-
tery.
Z
The factory settings of the battery selector switch must not be changed.
