Keep children away. Children must never be allowed in the work area. Do not
let them handle machines, equipment, or extension cords.
6.
Use the right inverter for the job. Do not attempt to force a small inverter or
attachment to do the work of a larger industrial inverter. There are certain applications for which this Inverter was designed. It will do the job better and more
safely at the rate for which it was intended. Do not modify this Inverter and do
not use this Inverter for a purpose for which it was not intended.
7.
Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically nonconductive clothes and nonskid footwear are recommended when working. Wear restrictive hair covering to contain
long hair.
8.
Always wear eye protection. When working around lead acid batteries, always
wear ANSI approved safety impact eye goggles, full face shield and work gloves.
When working under the vehicle’s hood, always be careful of hot engine parts.
9.
Do not overreach. Keep proper footing and balance at all times. Do not reach
over or across running machines.
10. Maintain inverters with care. Keep inverters clean for better and safer performance. Follow instructions for changing accessories. Inspect inverter cords
periodically and, if damaged, have them repaired by an authorized technician.
11. Disconnect power. Unplug inverter when not in use.
12. Avoid unintentional starting. Be sure the switch is in the Off position when
not in use and before plugging in any appliance.
13. Stay alert. Watch what you are doing, use common sense. Do not operate any
inverter when you are tired.
14. Check for damaged parts. Before using any inverter, any part that appears
damaged should be carefully checked to determine that it will operate properly
and perform its intended function. Check for alignment and binding of moving
parts; any broken parts or mounting fixtures; and any other condition that may
affect proper operation. Any part that is damaged should be properly repaired or
replaced by a qualified technician. Do not use the inverter if any switch does not
turn On and Off properly.

Guard against electric shock.
Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures during installation.
Connect all wires securely.
Store metal objects away from the inverter.
19. People with pacemakers should consult their physician(s) before using
this product. Electromagnetic fields in close proximity to a heart pacemaker
could cause interference to or failure of the pacemaker.
20. Keep the Inverter well-ventilated. Do not place any objects on top of or next to
the Inverter or allow anything to cover the cooling fans; doing so can cause the
Inverter to overheat, causing a potential fire hazard and/or damage to the Inverter. Leave adequate ventilation space underneath the Inverter as well; thick
carpets or rugs can obstruct air flow, causing the Inverter to overheat.
21. A vehicle’s engine must never be used in any sealed structure. Carbon
monoxide is produced during operation and is DEADLY in a closed environment. Early signs of carbon monoxide poisoning resemble the flu, with
headaches, dizziness, or nausea. If you have any of these signs, get fresh air
immediately.
22.
Risk of explosion! Hydrogen gas is explosive. NEVER smoke when
working with batteries. Lead acid batteries generate hydrogen during normal operation, and more is generated while the battery is charging.
23. Proper Battery Care: Battery leakage may occur under extreme usage or temperature conditions. If Battery fluid comes in contact with skin, wash with soap
and water and rinse with lemon juice and vinegar. If the fluid comes into contact
with the eyes, flush with water for several minutes and contact a doctor immediately. Never burn the Battery, as it can explode in a fire. Do not use the Battery
Charger on a vehicle with a leaking Battery. Contact local solid waste authorities for instructions on correct disposal or recycling of the Battery.
Note: Performance of this unit may vary depending on the available battery power or
appliance wattage.
Warning: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions and situations that may occur. It
must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

Connection
For the power Inverter to work properly, your power source must provide 12 volts DC,
and enough current (i.e., 32 amps to operate a load of 384 Watts or under).
Warning: This Inverter must only be connected to batteries with a nominal output voltage of 12 volts. 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.
Strip the insulation off of the last 3/4” of each Battery Cable (not included; #4-#0
AWG cable recommended). Insert the Cables into the (Positive) red and (Negative) black terminals on the back of the Inverter. Securely tighten the Screw on
top of each connection. Connect the Ground Cable (not included; #6 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 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,

Troubleshooting Tips
1.
If the low battery alarm sounds, this means that the input voltage is below the
necessary 11 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 weak TV 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 490 watts. Also,
keep input voltage above 11 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.
