DANGER! Danger of electrocution
• 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 from the land, you must install a residual current
circuit breaker between the 230V mains supply and the refrigerator.
Seek advice from a trained technician.

NOTE
Always connect the refrigerator to the rectifier. Otherwise the priority
circuit for the refrigerator will be disabled.
The priority circuit reduces the load on a connected battery by the
rectifier always switching to mains operation if AC power is connected.
Proceed as follows when you connect the refrigerator to the AC supply:
➤ Fix the rectifier as shown in the location foreseen, behind the refrigerator (fig. g,
page 9).
➤ Protect the AC circuit using a slow-blow fuse (250 V/4 A).
➤ Connect the power cable to the AC power supply.
➤ Plug in the connecting cable to the AC socket (fig. g 1,page 9).
Proceed as follows when you connect the refrigerator to a DC supply when a rectifier
is fitted:
➤ Connect the loose DC cable (fig. g 2, page 9) to the battery:
– Red cable: positive battery terminal
– Black cable: negative battery terminal
