9. Turn the appliance on.
Attention:
Loose connections can cause a large voltage drop to occur which may result in damage to the wires and
insulation. If you do not make a secure connection between the inverter and the power source, a reverse
polarity will occur. The green LED Indicator briefly flashing when you first turn the inverter ON is a sign that
there is a short circuit within the power supply.
Damage caused by reverse polarity is not covered under the warranty.
When connecting the RED (positive, (+)) terminal to the 12 volt power source's
POSITIVE (+) terminal, a spark may occur as a result of current flowing to charge capacitors within the inverter.
This is a normal occurrence.
Because of the possibility of this sparking, it is critical that both the inverter and the 12 volt battery be placed
well away from any possible source of flammable fumes and/or gases.
Failure to heed this warning could result in fire or explosion
Grounding the Inverter
Locate the Grounding Lug on the inverter. Run a wire of 0 AWG from the Grounding Lug to a proper
grounding point. You may connect this wire to the chassis of the vehicle. Also, grounding may be done by
running the wire to an earth ground. Before connecting the ground ensure the inverter is turned off. Operating
the inverter without properly grounding may result in risk of electrical shock.
Using the Inverter to Operate a TV or Audio Appliance
This inverter is shielded and filtered to minimize signal interference. Despite this, some interference may
occur with your television picture, especially with weak signals. Below are some suggestions to try and improve
reception.
1. Make sure the television antenna produces a clear signal under normal operating conditions (i.e., at home
plugged into a standard 110 AC wall outlet). Also, ensure that the antenna cable is adequately shielded and of
good quality.
2. Try altering the positions of the inverter, antenna cables, and television power cord.
3. Add an extension cord from the inverter to the TV so as to isolate it, its power cord and antenna cables from
the 12 volt power source.
4. Try coiling the television power cord and the input cables running from the 12 volt power source to the
inverter.
5. Affix one or several "Ferrite Data Line Filters" to the television power cord. Ferrite
Data Line Filters can be purchased at most electronic supply stores.
Some inexpensive audio systems may discharge a slight buzzing sound when operated by the inverter.
This is caused by deficient filters in the audio system. This is unavoidable in some cases.
Operating a Microwa ve
The power rating of a microwave oven is the "cooking power"which is being delivered to the food. The actual
operating power requirement rating is higher than the cooking power. This is usually referenced on the back of
the microwave. If the operating power requirement cannot be found on the microwave itself check the User
Manual.
Attention:
Although it is not necessary to disconnect the inverter when turning over the engine, it may briefly cease to
operate as the battery voltage decreases.
When the inverter is not supplying power, it draws very low amperage from the battery. The inverter may be left
connected to the battery for up to three hours.
It is recommended that the inverter always be disconnected when not in use.
Safety Features
The GREEN LED Indicator light will turn OFF; the RED LED Indicator light will turn ON and the inverter will
automatically turn itself off when:
1. The power input from the battery drops to 10 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 volts.
3. The continuous load demand from the equipment or appliance being operated exceeds 5000 watts.
4. The circuit temperature exceeds 165°F (74°C)
