Try this solution

Reset the error code by pushing and holding the encoder button for 3 seconds

Possible cause: Cable cross-section too small or cable too long.

Replace the cable according to the Step-by-Step Guide below.

1

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).

12 V24 V
Cut-off voltage10.4 V22.8 V
Cut-in voltage11.7 V24.2 V

3

Check if the operating voltage and the battery voltage match

Before starting up the device for the first time, check whether the operating voltage and the battery voltage match (see type plate).

4

Connect the cable to the refrigerator DC terminal block (1).

5

Connect the refrigerator
