7.4 Connecting the refrigerator
Connecting the refrigerator to DC voltage
A
The refrigerator can be operated with a 12 V or a 24 V DC voltage supply.
For safety reasons, the refrigerator is equipped with an electronic system to
prevent the polarity being reversed. This protects the refrigerator against
reversed polarity when connecting to a battery and against short circuiting.
To protect the battery, the refrigerator switches off automatically if the voltage
is insufficient (see table below).
➤
Determine the required cross section of the cable in relation to the cable
length according to fig.

➤
Before starting up the device for the first time, check whether the operat-
ing voltage and the battery voltage match (see type plate).
NOTICE!

To avoid voltage drops and loss of performance, keep the con-
nection cable as short as possible and not be interrupted.
Therefore avoid additional switches, plugs or power strips.
 Disconnect the cooling device and other electric consumers
from the battery before you connect the battery to a quick
charging device. Overvoltage can damage the electronics of
the device.
