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.
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).
