12 V outputs
Consumer
The output to the consumers (fig. 4, pos. 7, contact 1 to 3)
only carry +12 V, if the user relay has switched on. The consu-
mer relay only switches if there is a control current of +12 V
on the contact no. 4 of the 7-pin plug (fig. 4, pos. 8). The con-
sumer circuits are each fitted with a 20 A fuse.
Heating and immediate light
Heating and immediate light are supplied independently of the
consumer relay. They are connected to the continuous current
(contact 4) and fitted with a 20 A fuse.
Water pump
The freshwater pump (contact 5) is supplied via the pump
relay. It is protected with a 10 A fuse. This circuit is regulated
from the control panel via contact no. 7 of the 7-pole plug
(fig 4, pos 8).

When the engine is running, the refrigerator is supplied with
power via the generator of the vehicle. After the engine is
switched off, the refrigerator relay disconnects the refrigera-
tor from the supply battery. The control action is via the cable
from the D+ of the generator. Thus, operating the refrigerator
at 12 V is only possible during journeys. When the vehicle
is parked, the refrigerator can only be run on gas or mains
voltage. This prevents the supply battery running down. This
circuit (contact 6) is protected by a 20 A fuse.

The refrigerator is supplied with continuous current if the main
switch on the operating panel is switched on.
