ELECTRICAL CONNECTION

The electrical installation must be carried out by authorised personnel.

NOTE! For mains voltage operation, it is important that the circuit to and in the motorhome is effectively earthed.

The refrigerator is equipped with a three-prong (grounding) plug for your protection against shock hazards and should be plugged directly into a properly grounded threeprong recep- tacle. DO NOT cut off or remove the grounding prong from this plug.

If the supply cord is damaged, it must be replaced by the manu- facturer, its service agent or similarly qualified persons in order to avoid a hazard.

230-240V SUPPLIES

Check that the voltage stated on the data plate is the same as the main voltage in use (230-240V).

NOTE! Electrical leads must be routed and secured so that they cannot come into contact with hot or sharp parts of the refrigerator.

CROSS-SECTIONS

The D+ (alternator) is a signal cable and therefore 1-1.5 mm2 is sufficient. Connection to 12V + and - must be done with a 10 mm2 wire if the total wire length (+ and - wire together) is maximum 12 m. If longer leads are needed, bigger dimensions are required.

MOUNTING INSTRUCTIONS

REPOSITIONING THE HINGES

The refrigerator is equipped with reversible doors. A special door reversing kit must be used to reverse the doors. For further information, contact your dealer.

MOUNTING THE DOOR PANEL

Door panels can easily be fitted or changed. RM 2455, RM 2555 and RM 4605 are delivered with door panel(s) wheras RM 2355 is delivered without.

Before starting the mounting work, read the instructions thor- oughly and check that the panel dimensions are in compliance

The free length of the cord is 1 m. It is recommended that the receptacle is located on the left side of the refrigerator (viewed from the rear) and approximately 150 mm from the floor. This allows easy access through the vent door. The cord should be routed to avoid direct contact with

the burner cover, flue cover or any other components that could damage the cord insulation.

12V AND “D+” CONNECTION

The 12V connection of the refrigerator is shown in Fig. 19. The (+12V) and (-) pole have to be connected directly to the “house battery”. Do not use the chassis for the return lead.

12V supply must not be connected to a voltage controller or similar device as the AES itself monitors the DC voltage.

+12V should be permanent attached, and must not be cut out when the ignition key is turned off. All connections should be screwed or soldered to keep voltage drop to a minimum. The 12V DC heater is fused with a 30 A in-line fuse.

The connection D+ (alternator) has to be connected to the corresponding outlet of the vehicles electrical system, either a 12V or a 24V DC alternator.

D+D+

Only 12V DC to the PC board. Under no circumstances can 24V DC be connected to the PC board.

12V or a 24V DC alternator

NOTE! Only 12V DC can be connected to the PCB.

Please consult a specialist, if you are not familiar with the 12V electrical system in your motor home.

826±1 mm (lower door)

We recommend that the panel is mounted before the refrigerator is installed in the enclosure. The lower decoration strip and parts bag are taped inside the door.

To mount the door panel, follow these steps:

1.

Slide the panel from the bottom of the door

into the grooves on the vertical edges of the

door.

2.Push the panel upwards. Take the two plastic panel stops from the parts bag and put them in the two holes at the lower door frame.

3.Put the decoration strip across the door and fasten it with three screws from the parts bag.
