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.
5. Wipe unit surfaces thoroughly with a dry cloth.
6. Resume operation.
