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 (i.e., at home plugged into a standard 110V AC wall outlet). 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.
Inverter Protection Features.
The RED LED Indicator light will turn on and the inverter will turn itself off automatically when:
1. The power input from the battery drops to 9.5 volts.(When the power input drops to 10.5
volts, an alarm will sound for an extended period).
2. The power input from the battery exceeds 15.5 volts.
3. The continuous draw of the equipment or appliance being operated exceeds 800 watts.
4. The surge draw of the equipment or appliance being operated exceeds 1600 watts.
5. The circuit temperature exceeds 165°F.
Note:
z The inverter is equipped with a cooling fan, which is designed to run for several seconds
upon startup, but will turn off until the temperature reaches 50°C - 60°C (122°-140°F) while
the inverter is operating, at which time it will turn on again to cool the inverter. Automatic
shut down caused by high circuit temperatures will occur when the cooling fan is unable to
maintain a cool enough temperature for safe operation of the inverter.
z In the event of automatic shut down or continuous audible alarm, turn the inverter rocker
switch to the OFF(0) position until the source of the problem has been determined and
resolved.
Safety Precautions.
For best results place the power inverter on a reasonably flat surface.
z Keep the inverter dry. Do not expose it to rain or moisture.
DO NOT operate the inverter if the inverter, device being operated or any other surfaces that
may come in contact with any power source are wet. Water and many other liquids can
conduct electricity, which may lead to serious injury or death.
