WARNING!
Positive
Negative
Risk of Fire!
The positive battery
terminal connection
must be the LAST
connection and must
be done with the
Ground
inverter’s switch off.
Connection
For the power inverter to work properly, your power source must provide 12 volts DC,
and the power source must provide enough current (i.e., 46 amps to operate the load
of 560 Watts or under).
Caution:This inverter must only be connected to batteries with a nominal out-
put voltage of 12 volts. Lower voltage will not operate the inverter properly, and
more voltage could damage the inverter or the device being powered. If more
than one 12 volt battery is to be used, the batteries must be connected in a
parallel circuit; batteries connected in a series circuit will produce too much
voltage.
1. Place the Power Inverter on a flat surface. Make sure it has adequate ventila-
tion and is not in direct sunlight. Fasten the inverter securely to the surface,
using screws or some other means. If holes are to be drilled, follow safe, proper
installation techniques.
2. Connect the Battery Cable (not included;#2 AWG or larger cables recommended)
lugs to the (Positive) red and (Negative) black terminals on the back of the
Inverter, see BACK above. Connect the Ground Cable (not included;#4 AWG or
larger cable recommended) lug to the Ground terminal, see BACK above. Se-
curely tighten.
3. The Power Inverter can be used either while the engine is running or off. Con-
nect the Battery Cables (not included) to the Negative (black) and Positive (red)
terminals of the battery.
4. Connect the Ground Cable to the appropriate location below:
a. If this unit is mounted within a vehicle with a grounded metal chassis,
attach the Ground Cable to a nearby location on the chassis.
b. If this unit is mounted in a boat or vehicle with an ungrounded chassis,
attach the Ground Cable to the vehicle’s grounding system.
c. ONLY if this unit is being used outside a vehicle,
attach the Ground Cable to the Negative Terminal of the Inverter.

Operation
Warning: NEVER operate this inverter unless it is properly grounded.
1. Plug the 115VAC device(s) you wish to power into the 3-prong AC Receptacles.
See FRONT above.The appliance(s) must not use more than 1,000 (total) watts
during continuous operation, otherwise it may overload the Inverter.
Caution:Some rechargeable appliances may damage the Power Inverter or the
appliance. When first using a rechargeable device, check the inverter’s tem-
perature for the first 10 minutes. If it becomes abnormally hot, do not use this
device with the Inverter.
2. Flip the Power Switch to the ON position to turn on. Do not use the appliance
until the switch illuminates.
3. Turn on appliance. If an alarm sound is heard, turn off the appliance.
Caution: It is recommended that the vehicle be started every hour to recharge
the battery. Doing this will help prevent any unexpected shutdown of the equip-
ment. This will also help ensure that there will be enough battery power to start
the vehicle. Due to the risk of carbon monoxide inhalation (see Warning # 22 on
page 4), do not run the vehicle’s engine within an enclosed area.
4. After use, disconnect the appliances and flip the Switch to the OFF position.

Troubleshooting Tips
1. If the low battery alarm sounds, this means that the input voltage is below the
necessary 10.5 V. The battery needs recharging. You should stop using the
appliance and then recharge the battery. If this is not done, the Inverter will shut
off automatically at around 10 V.
2. If you are unsure if the inverter will have the proper amount of current to run the
device, use this rough guideline: Take the power consumption of the load in
watts and divide it by 12 (input voltage). The result will be the approximate
number of amps needed to power your device.
Example: Load is rated at 312 watts. 312 watts / 12 V = 26 amps needed. You
could use this device with the inverter.
3. If your television will not start, it is important to keep in mind that some appli-
ances (including many televisions) may require two to six times their wattage to
start up.
4. If your audio system buzzes while using this inverter, it is because some sound
systems can not filter out the modified sine wave produced by the inverter. Use
a sound system that incorporates a higher quality power supply.
5. This inverter is made to minimize the interference with TV signals. However,
especially with weak TV signals, some interference may still be visible. To
correct this, place the inverter as far away as possible from the television an-
tenna and it’s cables. Next, adjust the orientation of the inverter to the antenna
cables and TV power cord to minimize the interference. Also, use a shielded
antenna cable.
6. If the low battery alarm is on all the time, try these corrective measures: Re-
charge battery if in poor condition. Next, check the battery connection. You
may need to clean the connectors.
7. If you are getting a low output voltage, try reducing the load to minimize watts.
You may have overloaded the inverter. Reduce your load to 950 watts. Also,
keep input voltage above 10.5 volts to maintain a constant flow of power.
8. If you are not getting any power output, turn the power switch Off and On again,
until the green power light comes on. Your devices may draw too much power to
operate them. The inverter may be in thermal shutdown. Let it cool down and
make sure there is adequate ventilation around the unit.
