Caution! Do not allow an AC device to be plugged into the Power Inverter when starting the
vehicle. Always remove the Power Inverter from the cigarette lighter socket when it is not in
use.
4. Connecting the Power Inverter for loads over 150 watts and less than 400 watts
Caution! You must connect the Power Inverter directly to a battery if you are going to
operate loads greater than 150 watts. Make sure the battery’s output voltage is within 10.5
to 15 volts. This Power Inverter will not operate if it is connected to a DC power lower than
10.5 volts. It will be damaged if it is connected to a DC power greater than 15 volts and
warranty will be voided.
1) Place the Power Inverter on a flat, secure and dry surface like the floor of your
vehicle.
(Picture 2, above)
2) Make sure the power switch (On/Off) on the front panel is off.
3) Take the cable with the battery clips and place the ring terminals over the two
DC input terminals on the back of the Power Inverter. Make sure to connect
to the right terminals, with red to red and black to black. Tighten the screws
on the DC input terminals.

4) Fasten the red (positive, +) clip to the positive battery post and then fasten the
black (negative, -) clip to the negative battery post. Please wear protective
eyewear and clothing when you use the Power Inverter or work with the
batteries. Do not contact the battery terminals with any metal tools or
personal metal objects like watches, rings and/or bracelets.

Caution! Please make sure positive clip to the positive battery post and negative clip to the
negative battery post. Reverse polarity connection will blow the fuse in the Power Inverter
and may permanently damage the product. Damage caused by reverse polarity connection
is not covered by warranty.
5) Turn on the power switch on the front panel. The Power Inverter’s green
LED indicator should light up. This signifies the Power Inverter is operating
properly and ready for use.
6) Plug the AC device(s) into the two three-prong receptacles and turn it on. If
you plug two devices at the same time, make sure they consume 400 watts or
less AC power together.
