CRX50DC, CRX65DC, CRX80DC, CRX110DC
You can connect the refrigerator to 100 – 240 Vw AC power if you use the MPS 35
rectifier (accessory).
The MPS35 rectifier features a priority circuit which conserves the battery connected. When a 100 – 240 Vw mains connection is used, the rectifier automatically
switches from battery to mains operation.
• Never handle plugs and switches with wet hands or if you are standing on a wet surface.
• If you are operating your refrigerator on board a boat with an
AC mains connection using a shore connection, you must install a
residual current circuit breaker between the AC mains supply and
the refrigerator.
Seek advice from a trained technician.
When disconnected from the 100 – 240 Vw mains supply, the rectifier automatically
switches back to battery operation. Mains operation via the rectifier always takes priority over battery operation.
In mains operation the output voltage of the rectifier will always be 24 V. When the
rectifier is in 12 V or 24 V battery operation, the input voltage will be passed through
so that the output voltage equals the input voltage.
Proceed as follows when you connect the refrigerator to the AC supply:
➤ Attach the rectifier on the back of the refrigerator.
➤ Connect the rectifier as shown in fig. h, page 12.
➤ Connect the refrigerator to the rectifier (fig. h 2, page 12):
– Red cable: positive battery terminal
– Black cable: negative battery terminal
➤ Plug the connector into the AC socket (fig. h 1, page 12).
