NOTE: Do not turn on the inverter or the power source until the inverter and the power source
are grounded.
To ground the inverter:
Turn off and disconnect the inverter.1.
Locate the chassis ground screw below the negative terminal on the left side of the 2.
inverter.
Remove the outer hex nut and loosen the second hex nut.3.
Strip the insulation of the #8 AWG copper wire back 1.5” and wrap the bare end of the 4.
wire around the ground screw between the two washers.
While holding the wire in place, tighten the hex nut securely. Then, replace the other 5.
hex nut and tighten it securely.
Attach the other end of the wire to a properly grounded location:6.
VEHICLE: Connect to the chassis, unpainted frame part, or engine block of the vehicle.
BOAT: Connect to the boat grounding system.
FIXED LOCATION: Connect to a ground rod or other appropriately rated ground.
Inverter Connection:
Locate the Positive and Negative plastic terminals located on the left side of the inverter. 1.
Using a standard (athead) screwdriver, unscrew the positive (red) and negative (black)
terminal screws just enough to be able to insert the bare end of the connector cables.
Insert the bare end of the positive (red) cable into the positive (red) terminal. Insert the 2.
bare end of the negative (black) cable into the negative (black) terminal. Tighten each
terminal screw so that the cable cannot come loose.
Connecting Inverter Cable to 12V Battery or 12V Power Source:
RISK OF CONTACT WITH BATTERY ACID. BATTERY ACID IS
A HIGHLY CORROSIVE SULFURIC ACID.
A SPARK NEAR THE BATTERY MAY CAUSE A BATTERY EXPLOSION. TO
REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
Keep hands, hair, clothing and jewelry clear of battery terminals.1.
Wear eye protection and clothing protection.2.
For a negative-grounded vehicle, connect the POSITIVE (RED) terminal from the 3.
inverter to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect the
NEGATIVE (BLACK) terminal to the vehicle chassis or engine block away from the
battery. Do not connect the terminal to the carburetor, fuel lines or sheet-metal body
parts. Connect to a heavy gauge metal part of the frame or engine block.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) terminal from the 4.
inverter to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the
POSITIVE (RED) terminal to the vehicle chassis or engine block away from the battery.
Do not connect the terminal to the carburetor, fuel lines or sheet-metal body parts.
Connect to a heavy gauge metal part of the frame or engine block.
To disconnect the inverter, reverse the above steps.5.
NOTE: The internal speaker may make a brief “beep” when the inverter is being connected to
or disconnected from the 12 volt power source.
Failure to make the correct connections will result in blown fuses and
permanent damage to the inverter.
