Connecting the refrigerator to DC voltage

A
NOTICE! Damage hazard
• 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. 7, page 6.

NOTICE! Damage hazard
Make sure the polarity is correct.
➤ Connect your refrigerator to a plug socket which is fuse-protected with at least
15 A (at 12 Vg) or 7.5 A (at 24 Vg) (fig. 8 1, page 6).
➤ Connect the red cable (fig. 8 rd, page 6) to the positive terminal of the battery.
➤ Connect the black cable (fig. 8 bk, page 6) to the negative terminal of the
battery.
