electrical connection
120 v ac connection
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 three prong recep-
tacle. Do not cut or remove the grounding prong from this
plug!
The free length of the cord is 3 feet. It is recommended that the
receptacle is located to the right side of the refrigerator (viewed
from the rear).
The receptacle should be 3" (from the
bottom of the plastic receptacle) above
the refrigerator mounting floor. This
allows easy access through the vent
door. The cord should be routed to
avoid direct contact with components
that could damage the cord insulation.
12v dc
The refrigerator requires a continuous 12V DC supply to
maintain operation. The DC supply connection is made to the
positive (+) and negative (-) terminals of the terminal block on
the 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. It is important that the wires to the 12V DC
terminal is of proper wire size.
The following table displays the recommended size and length
of the conductor wires.
maximum total conductor wire length
Wire length
17 ft (5 m)
27 ft (8 m)
Example: If the distance between the refrigerator and the
12V DC supply is 17 ft, the total wire length is 34 ft and a wire
size of 14 AWG should be used.

alternator (d+) connection
D+ connection is only valid for models with the
automatic door locking system. The refrigerator requires the
connection of a signal wire from the alternator (D+) in order
to maintain the automatic door travel latch and the temporary
gas lockout function. The gas operation will automatically
be locked out for a period of 15 minutes when the engine is
switched off. This will prevent gas operation e.g. when stop-
ping at a refueling station.
Connect the vehicles alternator (D+) to the D+ on the
terminal block.
