We recommend a fuse of type “CNL”, mounted on a fuse holder, type “CNL.” Plug one terminal of the small and the long cable’s
sections on the fuse holder, as illustrated in figure 5, and install the fuse. Without tightening them too much, the terminals must be
solidly fixed onto the fuse holder, and must not be able to move around.
CAUTION!
Not installing a fuse can result in fire that may cause severe injuries and/or damages.
3.6.2 Preparation of the cable connected to the negative side
Determine and cut the length of cable which you need to connect the negative side (-) of the battery to that of the inverter, without
forgetting the necessary length to allow movements due to the suspension of the cabin. Strip approximately a half-inch of insulation
from the two ends of the cable, insert the cable through the second PVC strain relief, and install good quality tin plated terminal lugs on
the stripped sections. Crimp the terminals with a hand held crimping tool (the use of a locked plier (Vice-Grip) is not recommended)
until the whole cable is crimped and then cover each section of stripped cable with good quality BLACK shrinkable tubing (refer to
Figure 4).
3.7 Connecting the Inverter
The next step is to make sure that the inverter is turned OFF. Insert the rubber insulators (included with the inverter) on the terminal
lugs and connect the cables (terminal lugs) to the inverter’s DC input terminals: the terminal covered with the RED shrink tube to the
positive (+) pole and the terminal covered with the BLACK shrink tube to the negative (-) pole. Make a secure connection using the
nuts included with the inverter. The terminal must not move around on the DC terminal, but it must not be too tight either. T he rubber
insulators will protect the DC connections and will prevent the terminal from being touched by other metallic pieces.
CAUTION!
Never put a washer or a nut between the terminal lugs and the 24 volts DC input terminals; this results in
poor conductivity and may cause the inverter to overheat and cause a fire.
Tighten the PVC strain relief nut on the cables until the rubber seal is properly compressed and the cables cannot move. Run the cables
under your cab and cover them with plastic loom to prevent damage from road debris. Fasten both cables together every 4 inche s with
plastic cable ties; try to run both DC (24 volts) cables as close as possible together to reduce the risk of interference with your
television or CB radio. While keeping in mind to allow cables to move with your cabin air suspension, secure the cables to the chassis
from the cabin’s floor to the batteries with several metallic clamps covered with rubber. These clamps will prevent the cables from
being cut or damaged by the vehicle’s vibrations.
3.8 Connection of the batteries
If you are working with a multiple battery bank, choose a battery with no accessory connected, as it will extend your battery’s life.
Before going further, it is important to correctly identify the cable connected to the positive terminal of the inverter, and the one
connected to the negative terminal. The cables must go from the positive terminal of the inverter to the positive terminal of the
battery, and of the negative terminal of the inverter to the negative terminal of the battery. Incorrectly connecting the battery
and inverter will damage your inverter permanently and is not covered by the warranty. Always connect the positive terminals
before the negative.
CAUTION!
Reversing the polarity when connecting the DC cables will permanently damage your inverter. THIS IS
NOT COVERED BY THE WARRANTY.
3.8.1 Positive Terminal
Always connect the positive terminals before the negative. Plug the small section of the cable connected to the positive terminal of the
inverter to the positive terminal of the battery, by solidly fixing the terminal with the nut. Without tightening them too much, the
terminals must not be able to move around.
3.8.2 Negative Terminal
The last step is to connect the cable between the negative terminal of the inverter to the negative terminal of the battery, by solidly
fixing the terminal with the nut. Without tightening them too much, the terminals must not be able to move around.
