CROSS-SECTIONS

The D+ (alternator) is a signal cable and therefore 1-1.5 mm

2

is suffi cient. Connection to 12V + and - must be done with a 

10 mm

2 

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 fi tted 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 

with those given in the following table:

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:  

Slide the panel from the bottom of the door 

into the grooves on the vertical edges of the 

door.
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.
Put the decoration strip across the door and 

fasten it with three screws from the parts 

bag.

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 qualifi ed 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.

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 fl oor. This allows easy access 

through the vent door. The cord should 

be routed to avoid direct contact with 

the burner cover, fl ue 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.

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.
