The tow vehicle

is not wired to provide HC+, HC-, and D+ inputs to

the trailer.

The trailer

is wired to accept HC+, HC-, and D+ inputs from the tow

vehicle.

Trailer Wiring:

Red :

out to HC+

Orange :

out to engine run (D+)

Purple (LC+) : to house / leisure battery (positive)

Black (LC-) : to house / leisure battery (negative)

The refrigerator will not operate in DC mode with

this wiring configuration.

Part No. 636313A (10/9/2013)

The tow vehicle

is wired to provide HC+, HC-, and D+ inputs to the

trailer and the trailer

is wired to accept HC+, HC-, and D+ inputs

from the tow vehicle.

D+ is an “engine run” signal that is only present

while the engine of the tow vehicle is running.

Tow Vehicle Wiring:

HC+ : a fused wire from the vehicle battery (positive)

HC- : a wire from vehicle battery (negative)

D+ : a wire from D+ of alternator (+12V when engine is

running)

Trailer Wiring:

White :

out to HC-

Red :

out to HC+

Orange :

out to engine run (D+)

Purple (LC+) : to house / leisure battery (positive)

Black (LC-) : to house / leisure battery (negative)

NOTICE

The tow vehicle

is not wired to provide HC+, HC-, and D+ inputs to

the trailer.

The trailer

is not wired to accept HC+, HC-, and D+ inputs from the

tow vehicle.

Trailer Wiring:

White :

not wired

Red :

not wired

Orange :

not wired

Purple (LC+) : to house / leisure battery (positive)

Black (LC-) : to house / leisure battery (negative)

The refrigerator will not operate in DC mode with

this wiring configuration.

NOTICE

Refrigerator theory of operation:

At any time, while the engine of the tow vehicle is

running, the refrigerator will operate in Auto DC mode.

If the engine of the tow vehicle stops running, the

refrigerator will automatically change to the Auto Gas

mode.

When the engine of the tow vehicle

stops running (the D+ signal is no

longer available) the refrigerator gas

valve and igniter outputs cease for

15 minutes. After 15 minutes, the

refrigerator gas valve and igniter

outputs resume.

If the trailer is connected to shore power, the

refrigerator will operate in Auto AC mode.

Refrigerator theory of operation:

When the trailer is connected to shore power, the

refrigerator will operate in Auto AC mode.

When the refrigerator is disconnected from shore

power, the refrigerator will operate in Auto Gas mode.

Because the tow vehicle

is not wired to provide HC+,

HC-, and D+ inputs to the trailer, the refrigerator

will

not operate in DC mode.

Recommended Trailer Wiring - Norcold N3100 Series Refrigerators

Wiring Scheme 1

This figure shows the recommended trailer and

tow vehicle wiring and

does let the refrigerator

operate in all three (3) modes.

Wiring Scheme 2

This figure shows the recommended trailer wiring

only and

does not let the refrigerator operate

in DC mode. It

does let the consumer change

the tow vehicle wiring, to match that of Wiring

Scheme 1, at a later date.

Wiring Scheme 3

This figure shows optional trailer wiring and

does

not let the refrigerator operate in DC mode. It

also

does not let the consumer change the tow

vehicle wiring, to match that of Wiring Scheme 1,

at a later date.
