Installing and connecting the refrigerator
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. d, page 9.

NOTICE!
Make sure the polarity is correct.
➤ Before starting up the device for the first time, check whether the
operating voltage and the battery voltage match (see type plate).
➤ Connect your refrigerator to a plug socket which is fuse-protected with at
least 15 A (at 12 V) or 7.5 A (at 24 V) (fig. e 1, page 9).
➤ Connect the red cable (fig. e rt, page 9) to the positive terminal of the
battery.
➤ Connect the black cable (fig. e sw, page 9) to the negative terminal of
the battery.
