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 wire as recommended 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.
Television and Audio Suggestions
Although these inverters are shielded and filtered to minimize signal interference, some
interference with your television picture may be unavoidable, especially with weak signals.
However, here are some suggestions that may improve reception.
1. First, make sure that television antenna produces a clear signal under
normal operating conditions. Also, ensure that the antenna cable is properly shielded and
of good quality.
2. Change the positions of the inverter, antenna cables and television power cord.
3. Isolate the television, its power cord and antenna cables from the 12 volt
power source by running an extension cord from the inverter to the television set.
4. Coil the television power cord and the input cables running from the 12 volt power source
to the inverter.
5. Attach a "Ferrite Data Line Filter" to the television power cord. More than one filter may be
required. These filters are available at most electronic supply stores.
Note:
z Inexpensive sound systems may emit a "buzzing" sound when operated with the inverter.
This is due to inadequate filters in the sound system. There is no solution to this problem
short of purchasing a sound system with a higher quality power supply.
