Connecting the refrigerator to DC voltage

A
NOTICE!
To avoid voltage drops and loss of performance, keep the
connection 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.
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. d, page 10.

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 at 15 A
(at 12 V) or 7.5 A (at 24 V) (fig. e 1, page 10).
