To test the gas safety shut off, follow these steps:
Start the refrigerator without connecting to 1.
120V AC.
Check that the gas flame is lit. In AUTo mode,
2.
the AUTo mode indicator lamp is on.
Follow steps 3-11 in the previous instruction.

electrical connection
120 V aC connection
The refrigerator is equipped with a grounded three-prong plug
for protection against shock hazards. It should be plugged di-
rectly into a properly grounded three-prong receptacle. Do not
cut or remove the grounding prong from this plug!
The free length of the cord is 2 feet. It should be routed to
avoid direct contact with the burner cover, flue cover or any
other components that could damage the cord insulation.
To allow easy access through the vent door, it is recommended
that the receptacle is placed like this:

12V dC connection
RM2451, RM2551, DM2652 & DM2852 : These refrigerator
models are not designed for 12V DC operation of the cooling
system. However, 12V DC must be supplied to operate the
controls.
RM2354, RM2454, RM2554, DM2662, DM2663, DM2862,
DM3862 & NDM1062 : These refrigerator models require a
continuous 12V DC supply to maintain the automatic energy
system.
The connection is made to the positive (+) and negative (-)
terminals of the terminal block on back of the refrigerator.
Correct polarity must be observed when connecting to the DC
supply. Do not use the chassis or vehicle frame as one of the
conductors. Connect two wires at the refrigerator and route to
the DC supply. Ensure the connections are clean, tight and free
from corrosion.
Ensure that the wires from the battery to the refrigerator are
able to handle the load. The distance the current must travel
from the battery to the refrigerator dictates the AWG wire size
to be used. Inadequate wire sizes can result in a voltage drop
which affects the refrigerator performance.
For 3-way models, the voltage drop affects the wattage output
of the 12V cartridge heater and the refrigerator performance.
The 12V DC heater is fused with a 30 amp. in-line blade fuse.
