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 oor 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 ue pipe, or any hot component that could damage the insulation of
the power cord.
Connect the 12 volt DC supply :
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 re 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 N314E.3F 4 mm² 20 Amp
N414E.3F/N514E.3F 4 mm² 30 Amp
8 m N314E.3F 6 mm² 30 Amp
N414E.3F/N514E.3F 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 supplies are marked positive (+) and ground ( ). 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 DC power supply wires:
These models have 2 connection points to prevent the battery from being discharged
by the refrigerator when the engine is not running. The DC terminal block accepts 1/4”
receptacles. (See Art02517)
High current supply Terminal one (-) and terminal two (+) for heating element.
Only turned on if signal on terminal ve, D+
Low current supply Terminal three (-) and terminal four (+) for electronics.
D+ signal Terminal ve (+) when engine runs.
Do not use the chassis of the refrigerator or the vehicle frame as one
of the conductors. Attach the DC power supply wires only to the
battery and the terminal block of the refrigerator.
