RUC Refrigerator
The device does not cool, power is present, error indicator appears
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 V | 24 V | |
|---|---|---|
| Cut-off voltage | 10.4 V | 22.8 V |
| Cut-in voltage | 11.7 V | 24.2 V |
2
Determine the required cross section of the cable
Determine the required cross section of the cable in relation to the cable length according to the figure above.
| Coordinate axis | Meaning | Unit |
|---|---|---|
| l | Cable length | m |
| ∅ | Cable cross section | mm² |
NOTICE!
Make sure the polarity is correct.
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
Connect the cable to the refrigerator DC terminal block (1).
5
Connect the refrigerator
Connect the refrigerator
– as directly as possible to the poles of the battery
– with fuse protection fitted to the positive (+) side of the supply cable of 15 A (at 12 V) or 7.5 A (at 24 V).
