NOTICE!
Make sure that the polarity is correct.
➤ Before starting up the appliance for the first time, check whether the operating
voltage and the battery voltage match (see type plate).
➤ Connect the refrigerator
– as directly as possible to the poles of the battery or
– to a 12 or 24 Vg socket.
Fit a fuse in the positive wire of 15 A (for 12 V) or 7.5 A (for 24 V) (fig. f 1,
page 8).
➤ Connect the red cable (fig. f rt, page 8) to the positive terminal of the battery.

NOTICE!
Disconnect the refrigerator and other electric loads from the battery
before connecting the battery to a quick charging device.
Overvoltage can damage the appliance electronics.
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).
