Connect The 120 Volts Ac Supply; Connect The 12 Volts Dc Supply; Connect The Propane Gas Components; Connect The Propane Gas Supply System - Norcold 1200 Installation Manual

WARNING:
The rear of the refrigerator cooling system
has hot surfaces and sharp surfaces that can damage
electrical wiring. Make sure that there is a good clear-
ance between all electrical wiring and the cooling system
of the refrigerator. Position any electrical wiring within the
refrigerator enclosure opposite the burner side of the
refrigerator. Do not put any electrical wiring through the
roof exhaust vent. Failure to correctly position electrical
wiring can result in electrical shock or fire.

Connect the 120 volts AC supply:

WARNING:
Connect the AC power cord(s) only to a
grounded three-prong receptacle. Do not remove the
round ground prong from the AC power cord of the
refrigerator or the ice maker (optional). Do not use a two
prong adapter or an extension cord with either AC power
cord. Operation of the refrigerator without correct ground
can cause dangerous electrical shock or death if you are
touching the metal parts of the refrigerator.
Put the AC power cord(s) into a grounded three-prong recep-
tacle:
- Make sure the receptacle is positioned within easy reach of
the lower intake vent.
- Make sure the power cord(s) does not touch the burner
cover, the flue pipe, or any hot component that could
damage the insulation of the power cord.

Connect the 12 volts DC supply:

The refrigerator controls operate on 12 VDC power. As the
distance from the vehicle battery to the refrigerator increases,
the correct AWG wire size and fuse size also increases. If the
wire size is too small for the distance, a voltage drop occurs.
Use a minimum of 18 AWG wire and a maximum 6 Amp fuse. If
the wire size is larger than the min. size, use the correct fuse
per RVIA A119.2 standard or local codes.
1. Install a fuse in DC power supply wires between the battery
and the refrigerator:
- Put fuse as close to the battery as possible.
2. Connect the DC power supply wires (See Art01748):
- Attach a 1/4 inch Quick Connect terminal to each DC power
supply wire.
NOTE: Do not use the chassis of the refrigerator or the
vehicle frame as one of the conductors.
- Connect the positive DC power wire [50] to the teminal on
the power board [49] that is marked 12VDC.
Installation Manual 8
- Push the DC ground wire [51] onto the terminal of the power
board [49] that is marked GND.
- Make sure each DC power supply wire is on the correct
polarity terminal.

Connect the Propane Gas Components

Propane Gas Operation
Propane gas
(11 inches water column pressure)
12 volts DC control voltage
(10.5 volts min. - 15.4 volts max.).
This refrigerator operates on these energy sources. Operation
out of these limits can damage the refrigerator electrical circuit
parts and will void the warranty

Connect the propane gas supply system:

WARNING:
Be very careful when working on or near
the propane gas system.
- Do not smoke, or use an open flame near the propane
gas system.
- Do not use an open flame to examine for leaks.
- Do not connect the refrigerator to the propane gas tank
without a pressure regulator between them.
- To avoid a propane gas leak, always use two
wrenches to tighten or loosen the propane gas supply
line connections.
- Leaking propane gas can ignite or explode and result
in dangerous personal injury or death.
Connect the gas supply line to the refrigerator:
- Make sure that all tubing and fittings obey all local, state,
and national codes about size and type.
- Make sure that all flexible metal connectors obey the current
CAN1-6.10 Standard.
- Make sure that the materials used for the gas supply line
obey both the current ANSI A 119.2 (NFPA 1192) and CSA
Z240 Standards on Recreational Vehicles. Norcold
recommends the use of 3/8 inch copper tubing as the gas
supply line and requires a 3/8 inch SAE (UNF 5/8-18) male
flare fitting as the connection to the refrigerator.
- Put the propane gas supply line up through the floor of the
enclosure.
