CONNECTING THE INVERTER
Installation procedure:
1. Mount the inverter in a secure location. If the inverter is to be mounted on a wall, mount it
horizontally. Make sure that the front and rear of the inverter has free air flow.
2. Make sure the cables are the proper gauge and have the fuse holder as close to the battery
bank’s Positive (red) terminal.
3. Install the fuse in the Positive (red) cable.
4. Make sure the Power Switch located on the front panel of the inverter is in the Off position.
5. Locate the ground lug terminal on the inverter. Connect an insulated 10 gauge copper wire
to the terminal. The other end of the ground wire is connected to a “proper” grounding
point. Use the shortest practical length of wire. Connect this wire to the chassis of your
vehicle or to the grounding system in your boat. In a city, the ground wire can connect
to a metal cold water pipe that goes underground. In remote locations, the ground wire
can be connected to an “earth ground”. This can be an attachment to a foot long copper
clad metal rod driven into the ground. In the unlikely event of a short circuit, operating the
inverter without proper grounding can result in electrical shock. Do not directly connect
this ground wire to the Negative (black) DC Terminal of the inverter. As an alternative
grounding connection, use the Negative (black) terminal of the battery.
NOTE: Crimp-on ring terminals are required on all cable ends. The cable ends need to
be stripped of insulation for 1/2 inch before crimping on ring terminals. Select a crimp
terminal size to fit the gauge cable and inverter and battery terminal connectors. After
crimping make sure that the cable connectors are secure on the cables so there are no loose
connections.
6. Remove the terminal covers from the inverter. Slide the cable through the correct terminal
cover.
7. Connect the Negative (black) cable end to the inverter terminal and battery Negative
Terminal. Make sure you have good, secure connections.
8. Recheck and make sure the DC cable fuse is installed in the fuse holder.
CAUTION: Making an initial connection between the positive cable end and the inverter’s
positive terminal may cause a spark. This is a normal and is a result of capacitors in the
inverter starting to charge. Because of the possibility of sparking, it is extremely important
that both the inverter and the battery bank be positioned away from any source of
flammable fumes or gases. Failure to heed this warning can result in fire or explosion.
Do not make the positive terminal connection immediately after the batteries have been
charging. Allow time for the battery gasses to vent to outside air.
9. Attach the positive cable to the Positive DC connector on the battery and then the inverter.
Make sure the connections are tight and secure.
10. Turn on the inverter from the Front Panel Power Switch “|”
