11. 12 VOLT DC CONNECTION
2-WAY REFRIGERATOR MODELS
On 2-way refrigerator model RM2552, DC must be con-
nected to the refrigerator to provide power for operation of
the automatic reignitor. On this unit there is one terminal
block marked 12 volts, located on the back of the refrigera-
tor cabinet. (See FIG. 6A).

3 amps / 14 AWG
3-WAY REFRIGERATOR MODELS
WITH AUTOMATIC REIGNITOR
On 3-way refrigerator models with automatic reignitors,
there are two terminal blocks for DC. The DC terminal block
on the back of the refrigerator cabinet is for the reignitor;
and the DC terminal block located under a plastic cover on
the back of the refrigerator is for the refrigerator heater. See
FIG. 6A.
The refrigerator must be connected by a separate circuit
to the battery with two wires of adequate capacity to avoid
voltage drop when the DC heater is being operated. The
wire gauge should be chosen with consideration to the
length; refer to the Table below for wire size. The DC circuit
must be fused; refer to the Table for fuse size.

NOTE: The refrigerator Model RM2452 does not have an
automatic reignitor. The 3-way model has only one 12 volt
DC terminal block located on the back of the refrigerator.
DO NOT use the body or chassis of the vehicle as a
substitute for either of the two conductors. DO NOT
connect any other electrical equipment or lighting to
the refrigerator circuit.

DO NOT operate the refrigerator on 12 volt DC when
the vehicle is parked. The amperage draw of the 12 volt
DC heating element can discharge a battery in a very
short time. The installation of a 12 volt DC operated
refrigerator requires a relay to be installed on the tow
vehicle or in the caravan. The relay will automatically
shut off the 12 volt DC power to the refrigerator when
the ignition is turned off. (See FIG. 11).
