This inverter uses a nonsinusoidal waveform. Therefore we do not recommend you use it to power the following devices:

1.Switch Mode Power Supplies;

2.Linear Power Supplies;

3.Class 2 Transformers;

4.Line Filter Capacitors;

5.Shaded Pole Motors;

6.Fan Motors;

7.Microwave Ovens;

8.Fluorescent and High Intensity Lamps (with a Ballast); and

9.Transformerless Battery Chargers.

Doing so, may cause the device to run warmer or overheat.

4.CONNECTING INVERTER CABLES

The inverter and power source must be in the OFF mode.

Make sure you connect your inverter to a 12-volt power supply only.

Inverter connection:

1.Locate the positive and negative plastic terminals located on the back of the inverter and remove the terminal caps completely.

2.Install the positive (red) cable ring lug onto the positive (red) terminal screw. Install the negative (black) cable ring lug onto the negative (black) terminal screw. Tighten each terminal so that the cable cannot come loose.

Connecting inverter cable to a vehicle (120 watts maximum):

1.Remove the cigarette lighter from its outlet.

2.Push the 12-volt power plug firmly into the outlet.

Connecting inverter cables to 12v battery or 12v power source:

1.Keep hands, hair, clothing and jewelry clear of battery terminals.

2.Wear eye protection and clothing protection.

3.Connect the positive (red) inverter terminal cable to the power source positive (+) or battery terminal. Make sure the connection is secure.

4.Connect the negative (black) inverter terminal cable to the power source negative (-) or battery terminal. Make sure the connection is secure.

5.To disconnect the inverter, reverse the above steps.
