6.3 Connecting the refrigerator to the power supply
Connecting the refrigerator to 12 – 24 V
A
The refrigerator can be operated with a 12 V or 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 the figure above.
NOTICE!
• To avoid voltage drops and loss of performance, keep the
connection cable as short as possible and uninterrupted.
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.
