Installing and connecting the refrigerator
7.7 Connecting the refrigerator to DC voltage
A
NOTICE!
•
To avoid voltage drops and loss of performance, keep the
connection cable as short as possible.
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 DC voltage supply (12/24 Vg).
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 Vg) or 7.5 A (at 24 Vg) (fig. e 1, page 10).
