WARNING! This equipment contains components that tend to produce arcs or sparks. To reduce the risk of fire or
explosion, do not install in a compartment containing batteries or flammable materials, or in a location
that requires ignition protected equipment.
- Close to batteries:
Install the inverter as close as possible to batteries (but not in the same compartment) in order to minimize
the cable length required to connect the inverter to the batteries. It is better and cheaper to run longer AC
wire (between the inverter and your appliances) than DC cables (between the inverter and the batteries).
3.4 Mounting the inverter
When you have decided where to place it, mount the inverter on a flat surface using the mounting flanges. Mounting hardware should
be corrosion resistant, and 1/4” or larger. The inverter may be mounted horizontally on a vertical surface (the fans’ opening must not
point up or down) or on a horizontal surface. Upside down installation is not recommended, as it may put too much stress on the
housing of your power inverter.
Close to the inverter, drill two holes in the truck’s floor and install the two strain reliefs about 3 inches apart (Figure 3).

3.5 Ground
The inverter has a lug on the rear panel that must be connected, using a #10 AWG copper cable, to the chassis of your vehicle or to a
metallic panel connected to the chassis. This grounding procedure conforms to most electrical codes that require deriving AC sources
to ground in case of malfunctioning. To make sure that you found a good grounding point, run a 12 volt test light from the positive
terminal of your battery to your grounding point. If the light comes on, your installation is more than likely OK.
WARNING!
Do not operate the inverter if the ground screw of the inverter is not properly connected to the chassis of
your vehicle, it may result in electrical shock hazard.
3.6 Battery cables
Proper wiring is very important for safe and proper operation of the inverter. Since the inverter has a low voltage (24 volts) and a high
current input, low resistance wiring and connections between the batteries and the inverter is essential in order to deliver the maximum
amount of usable energy to your load. Don’t waste the investment you have made in a highly efficient inverter by using cheap and
undersized wires!
Use only covered, flexible, copper wires capable of withstanding temperatures in excess of 215° Fahrenheit. We recommend welding
cable as the best size & type for connection between the batteries and your inverter. Keep the cable length as short as possible, no
