7.6 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:
•12V: fig.d
NOTICE! DANGER OF DAMAGE
• 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.
