CRD0050 Installing and connecting the refrigerator
17
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).
Connecting the refrigerator to AC power (accessory)
D
You can connect the refrigerator to 100 – 240 V AC power if you use the MPS35
rectifier (
accessory ).
The MPS35 features a priority circuit which conserves the battery connected. When
a 100 – 240 V
w
mains connection is used, the rectifier automatically switches from
battery to mains operation.
When disconnected from the 100 – 240 V
w
mains supply, the rectifier automatically
switches back to battery operation. Mains operation using the rectifier always takes
priority over battery operation.
Proceed as follows when you connect the refrigerator to the AC supply:
➤
Affix the rectifier in its intended position behind the refrigerator (fig.
9
, page 6),
as shown.
➤
Protect the AC circuit using a slow-blow fuse (250 V/4 A) (fig.
9
3, page 6).
➤
Connect the rectifier as shown in fig.
9
, page 6.
➤
Connect the refrigerator to the rectifier (fig.
9
2, page 6):
– Red cable: positive battery terminal
– Black cable: negative battery terminal
➤
Plug the connector into the AC socket (fig.
9
1,page 6).
12 V 24 V
Cut-off voltage 10.4 V 22.8 V
Cut-in voltage 11.7 V 24.2 V
DANGER! Danger of fatal injury!
•
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 a mains
connection of 230 V using a shore connection, you must install a
residual current circuit breaker between the 230 V mains supply and
the refrigerator.
Seek advice from a trained technician.
