Operating Tips
The inverter should only be operated in locations that are:
DRY — Do not allow water or other liquids to come into contact with the inverter.
COOL — Surrounding air temperature should ideally be 10-20°C (50-68°F). Keep the inverter away from direct
sunlight, when possible.
WELL-VENTILATED — Keep the area surrounding the inverter clear to ensure free air circulation around the
unit. Do not place items on or over the inverter during operation. The unit will shut down if the internal
temperature gets too hot. The inverter will auto-reset after it cools down.
SAFE — Do not use the inverter near flammable materials or in any locations that may accumulate flammable
fumes or gases. This is an electrical appliance that can briefly spark when electrical connections are made or
broken.
CARE AND MAINTENANCE
Storage
1. Ideal storage temperature range is 0-40°C (32-104°F).
2. Store and use the inverter in a cool, dry place with adequate ventilation for all-around air circulation.
3. Avoid locations that are exposed to heating units, radiators, direct sunlight, or excessive humidity or
dampness.
Fuse Replacement
This inverter is equipped with multiple internal fuses. Normally, these fuses will not “blow” unless there is a
serious problem inside the unit. Internal fuses are replaceable; however, only trained personnel should attempt
fuse replacement. If the unit is damaged during fuse replacement, the warranty may be voided.
The fuse in the DC Accessory Outlet Plug is user-replaceable. Make sure to first disconnect the Outlet Plug from
any 12 volt DC power source; then replace the fuse with one of the same rating and type.
TROUBLESHOOTING
Common Audio/Visual Problems
Problem: Buzzing Sound In Audio Systems
Some inexpensive stereo systems and boom boxes make a buzzing sound when operated from the inverter,
because the power supply in the electronic device does not properly filter the modified sine wave produced by
the inverter. The only solution to this problem is to use a sound system that has a higher quality power supply.
Problem: Television Interference
The inverter is shielded to minimize interference with TV signals. However, in some instances, some
interference may still be visible, especially when the TV signal is weak. Try the following to improve the picture:
1. Move the Inverter as far away as possible from the TV set, the antenna, and the antenna cables. Use a short
AC extension cord, if necessary.
2. Adjust the orientation of the antenna cables, and the TV power cord to minimize interference.
3. Make sure that the antenna feeding the TV provides an adequate (snow-free) signal and that high quality,
shielded antenna cable is used.
Fault LED Lights
The red Fault LED indicates inverter shutdown from an over-load or over-temperature fault and the yellow Fault
LED indicates an input fault. See the “Protective Features” and “Common Power Output Problems” sections.
Common Power Output Problems
Possible Causes
Recommendations
Battery voltage below 10.0 volts
Recharge battery or check DC power supply.
Equipment being operated draws too much power
Reduce load to maximum 200 watts.
Inverter in thermal shutdown condition
Allow inverter to cool down. Ensure there is adequate
ventilation around the unit, and the load is no more
than 200 watts for continuous operation.
AC output is shorted
Unplug the AC appliance. Disconnect the unit from any
12 volt DC power source, then reconnect the unit
BEFORE plugging the appliance back in.
