NOTICE!
Disconnect the refrigerator and other consumers from the battery
before charging the battery with a quick charging device.
Over voltages can damage the electronics of the refrigerator.
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).
