Transformer H
The 230 V automatic circuit breaker (Fig. 89,1), the overload protection (Fig. 89,2)
and the main fuse (Fig. 89,3) are integrated in the power pack.
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.
When the overload protection triggers, the control button springs out ("OFF" posi-
tion).
Switching on overload
protection:
 Allow the power pack to cool.

overload protection are integrated in the power pack. If an LED underneath the
fuse (Fig. 90,2 or Fig. 91,3) lights up red, this indicates a defective fuse or a short cir-
cuit.
