Location Depending on the model, the transformer/rectifier is situated either in the bench
or in the bedding box.
9.5.1 Battery selector switch
The battery selector switch is used to set the charger module in the transformer/
rectifier to the type of living area battery installed in the vehicle ("lead acid" or "dry-
fill" battery).
9.5.2 Charging the battery
During driving the towing vehicle generator charges the living area battery. If the
engine of the towing vehicle is switched off, the transformer/rectifier separates the
starter battery of the towing vehicle from the living area battery so that discharging
of the starter battery of the towing vehicle through usage of 12 V living area appli-
ances is not possible.
When the vehicle is connected to the 240 V supply, the transformer/rectifier
charges the living area battery.
Z Further information can be obtained from the separate instruction manual
"Transformer/rectifier".

gas) can form. Danger of explosion!
