Installation Manual 10
Connect the 240 volt AC supply:
Connect the AC power cord only to a grounded three-prong power point. Do not remove the earth pin
from the power cord. Do not use a two-prong adapter or an extension 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 into a grounded three-prong power point:
- Make sure the power point is 100-150 mm above the floor of the enclosure and is positioned within easy reach of the lower intake
vent.
- Make sure the power cord 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 volt DC supply (3-way models only):
As the distance from the vehicle battery to the refrigerator increases, the correct wire size and fuse size also increases. If the wire
size is too small for the distance, a voltage drop occurs. The voltage drop decreases the output of the system heater and causes poor
cooling performance.
1. Determine the min. wire size and the max. fuse size to use:
If you use an incorrect wire size and/or fuse size, electrical fire can result.
- Measure the distance from the vehicle battery to the refrigerator and use the following size wire and fuse:
Distance
Models
Min wire size
Fuse size
5 m
N304M
4 mm²
20 Amp
N404M/N504M
4 mm²
30 Amp
8 m
N304M
6 mm²
30 Amp
N404M/N504M
6 mm²
40 Amp
- If the wire is larger than the min. size, use the correct fuse per local codes.
The wire connections must be clean, tight and free of corrosion. If any of these items are not correct:
- A voltage drop to the refrigerator will occur.
- The voltage drop will reduce the cooling performance of the refrigerator.
The terminals for connecting the DC power supply are marked positive (+) and negative (-). Make sure that:
- Each DC power supply wire is attached to the correct polarity terminal.
- The chassis or the vehicle frame is not used as one of the conductors.
- The DC power supply wires including the fuses are routed directly from the battery to the refrigerator.
2. Connect the D.C. power supply wires:
- Attach a fully insulated 6.35 mm Quick Connect terminal to each DC power supply wire.
- Push the positive (+) DC power wire onto the terminal block tab with the 12V (+) mark.
- Push the negative (-) DC power wire onto the terminal block tab with the 12V (-) mark.
- Make sure each DC power supply wire is on the correct polarity terminal.
