Note:
z Loose connections can result in a severe decrease in voltage, which may cause damage to
the wires and insulation.
z Failure to make a proper connection between the inverter and the power source will result in
reverse polarity. Reverse polarity will blow the internal fuses in the inverter and may cause
permanent damage to the inverter. Damage caused by reverse polarity is not covered under
the warranty.
z Making the connection between the Positive terminals may cause a spark as a result of
current flowing to charge capacitors within the inverter. This is a normal occurrence. Due to
the possibility of sparking, however, it is extremely important that both the inverter and the
12-volt battery be positioned far from any possible source of flammable fumes or gases.
Failure to heed this warning could result in fire or explosion.
3. Locate the Ground Lug Terminal at the rear of the inverter. Run a wire from this terminal to a
proper grounding point using the shortest practical length of wire as decribed on the last
page of this manual. You can connect this wire to the chassis of your vehicle or to the
grounding system in your boat. As an alternative when in remote locations the ground wire
can be connected to the earth (one way to accomplish this is to attach it to a metal rod
driven into the ground). Before connecting the ground, make certain that the inverter is
turned off.
Operating the inverter without correctly grounding the unit may result in electrical shock.
4. Turn On (I) the inverter. Make certain that the Over Load LED Indicators are not lit.
5. Turn OFF (0) the inverter. The Over Load and LEDS may briefly "blink". This is normal. The
internal audible alarm may also sound a short "chirp" This is also normal.
6. When you have confirmed that the appliance to be operated is turned off, plug the appliance
into one of the two 110v AC Outlets on the front panel of the inverter.
7. Turn the inverter on.
8. Turn the appliance on.
Note:
z The audible alarm may make a momentary "chirp" when the inverter is turned OFF(0). This
same alarm may also sound when the inverter is being connected to or disconnected from
the 12-volt power source.
z When using an extension cord from the inverter to the appliance
the extension cord should be no more than 50 feet long. At this
length there should be no measurable decrease in power from the inverter.
Operating a Microwave oven with Your Power Inverter
The power rating used with microwave ovens is the "cooking power" which qualifies as the
power being "delivered" to the food being micro waved. The actual operating power requirement
rating is higher than the cooking power rating. This is usually referenced on the back of the
microwave. If the operating power requirement cannot be found on the back of the microwave,
check the owner's manual or contact the manufacturer.
