INVERTER POWER SWITCH TURNED ON
Resetting the Unit
When a thermal shutdown problem occurs, the inverter will reset and turn back on automatically after it cools.
WARNING: To reduce the risk of injury or property damage: If the appliance stops working, even
momentarily, turn off the appliance and disconnect from the inverter until the cause is identified and
corrected.
CARE AND MAINTENANCE
Storage
1. Ideal storage temperature range is 50-68°F (10-20°C).
2. Store and use the inverter in a cool, dry place with adequate ventilation.
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.
Refer to the “Service Information” section of this Instruction Manual.
Preventive Maintenance
Inverters require minimal maintenance. For optimum performance, the manufacturer recommends periodically
performing the following preventive maintenance.
1. Turn OFF the inverter using the front panel ON/OFF Power Switch.
2. Remove the DC power fuse.
3. Check and tighten all electrical connections, including the ground.
4. Using a non-metallic vacuum cleaner hose, vacuum the air slots and fan area.
5. Clean the outside of the unit using a damp (not wet) cloth.
6. Wipe unit surfaces thoroughly with a dry cloth.
7. Re-insert the fuse and resume operation.
Trouble/Indication Possible Cause Suggested Remedy
No AC output — DC input is below 10 volts Recharge or replace battery.
red LED lit
Excessive appliance load Turn unit OFF. Reduce the load, wait for the
— thermal shutdown inverter to cool down, then turn the unit ON
again.
No AC output — Fuse(s) open Check DC input — fuse(s) in vehicle. Replace
green LED not lit the fuse with one of the same type and
rating if necessary.
Low battery alarm Low battery voltage Recharge battery. Remove load from the
sounds continuously inverter while recharging battery.
Bad connection or wiring Tighten all DC connections.
Motorized power tool Excessive start-up load If appliance does not start, appliance is
will not start drawing excessive current and will not work
with inverter.
Motorized power tool Purely inductive load Make the load not purely inductive. Operate
does not operate at an incandescent lamp at the same time as
correct speed motor.
Television/radio Snow in picture, Keep inverter and antenna distant from each
interference “buzzing” sound other. Use shielded antenna. Connect antenna
to amplifier.
