88 Caravan - 10-12 - EN
If the vehicle is not connected to the 230 V power supply, the requisite power
supply is provided by the battery of the towing vehicle, as long as contact 9 "Con-
stant positive" is connected to the towing vehicle socket (see connection diagram
at the end of this chapter). The 12 V living area lamps, the refrigerator, the cassette
toilet and the water pump can be used.
If the vehicle is connected to the 230 V power supply, the power pack switches the
power supply in the living area automatically from the towing vehicle battery to
mains operation. For Dometic type I the power pack must also be turned on.
Switched-mode power
supply
The power pack (Fig. 85,5 or Fig. 86,1) is mounted next to the 230 V automatic cir-
cuit breaker (Fig. 85,1 or Fig. 86,4).
A main switch (Fig. 85,4) (only Type I), several fuses (Fig. 85,2 or Fig. 86,2) and the
overload protection are integrated in the power pack. If an LED underneath the
fuse (Fig. 85,2 or Fig. 86,3) lights up red, this indicates a defective fuse or a short cir-
cuit.
The overload protection switches all 12 V appliances in the caravan off, if the power
pack overheats. The power pack can overheat, if the ventilation apertures are cov-
ered by clothing or if many 12 V appliances are operated for a long time.
Switching on the power pack
(only type I):
 Press the lower part of the main switch (Fig. 85,4): Position "ON". The green LED
(Fig. 85,3) lights up when 230 V voltage is present.
Switching on overload
protection (only type I):
 When the overload protection triggers, allow the power pack to cool.
 Press the upper part of the main switch (Fig. 85,4) first: Position "OFF".
 After about 60 seconds, switch the main switch back to position "ON".
