WARNING!  
Risk of Fire!  
Ground  
Negative  
Positive  
The positive battery  
terminal connection  
must be the LAST  
connection and must  
be done with the in-  
verter’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  
output 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 ventilation  
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. ConnecttheBatteryCable(notincluded;#2AWGorlargercablesrecommended)  
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.  
Securely tighten.  
3. The Power Inverter can be used either while the engine is running or off.  
Connect 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. Open the rubber cover on the receptacle(s) and plug the 115 VAC device(s)  
you wish to power into the 3-prong AC Receptacles. See FRONT above. The  
appliance(s) must not use more than 2,000 (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  
temperature 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 (I) position to turn on. Do not use the appliance  
until the green power LED indicator is on.  
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 system. Doing this will help prevent any unexpected shutdown  
of the equipment. 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, flip the Power Switch to the Off (O) position,  
and put the rubber covers back in place over the receptacles.

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 appliances  
(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 weakTV signals, some interference may still be visible. To correct  
this, place the inverter as far away as possible from the television antenna 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:  
Recharge 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 1,900 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.  
9. If the green light turns red, one of the following has happened:  
A. Input voltage is too low. B. input voltage too high C. Short circuit D. Inverter  
is near overload.
