Fault Protection and Troubleshooting Guide
Resetting the Inverter
After over-voltage or thermal automatic shutdown, your inverter will reset automatically. To manually reset the
inverter, turn the ON/OFF Switch to the off position, then back on.
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
Your 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 the inverter off using the front panel On/Off Switch.
2. Check and tighten all electrical connections, including the ground.
3. Using a non-metallic vacuum cleaner hose, vacuum the air slots and fan area.
4. Clean the outside of the unit using a damp (not wet) cloth.
PROBLEM/
INDICATION
POSSIBLE CAUSE
SUGGESTED SOLUTION
No AC or USB output —
Fault LED lit
DC input is below 10.7 volts
Excessive appliance load
Inverter hot
Recharge or replace (battery) power
source.
• Reduce load to inverter’s maximum
wattage output.
• Reset inverter by turning the Power
Switch off, then back on.
Disconnect all appliances from inverter.
Run inverter with no load for a few
minutes. Reconnect load.
No AC or USB output —
Power LED not lit
Bad connection or wiring
Check all connections to the (battery)
power source. Tighten if necessary.
Fault LED lights while
inverter is in use
Low (battery) power source voltage
Disconnect all appliances from inverter,
then recharge or replace (battery) power
source.
Power tool will not
operate when plugged
into inverter
Excessive start-up load
Power tool (or appliance) draws too
much voltage; and cannot be used with
your inverter.
Power tool will not
operate at correct speed
Purely inductive load
TH225:
Power tool cannot be used with
your inverter.
TH400/TH750:
Modify the load so that it
isn’t purely inductive; for example,
operate an incandescent lamp plugged
into the inverter’s other outlet at the
same time.
