How to Connect a Power Inverter

Using the screwdriver, loosen the retaining screw on the power inverter Positive (red) wire insertion socket. Insert wire end firmly into wire socket, and tighten screw so that the Positive lead wire is firmly in place. Loosen retaining screw on the Negative (black) wire insertion socket and insert the end of the second wire firmly into the socket. Tighten the Negative wire insertion socket screw so that the wire is firmly in place.

Connect the third wire to the grounding point on the power inverter. Because the power inverter has a grounding bolt with a hex nut at the end, the stripped end of the wire must be curled with the electrical pliers into a hook to attach to the grounding bolt. Once the wire has been curled, remove the hex nut from the grounding bolt, and slide the hook over the grounding bolt. Install the hex nut, thus clamping firmly the wire hook to the grounding bolt.

Connect the ground wire to a properly grounded source. If the power inverter is to be used to power a permanent electrical fixture, the ground wire should be connected to a building electrical ground point. If the power inverter is to be used as a temporary power source, the ground point may be connected to a "chassis ground" point (such as the frame of an automobile, if the power inverter is connected to an automobile battery as the DC power source).

Connect the Negative wire--which is connected to the Negative (black) wire insertion socket--to the negative terminal (-) on the battery. Connect the Positive wire--which is connected to the Positive (red) wire insertion socket--to the positive (+) terminal on the battery. Turn on power inverter switch. The power outlets should be capable of supplying household electrical power.
