TROUBLESHOOTING

PROBLEM: Low or No Output Voltage

Reason/Solution

1.Poor contact at terminals. Unplug and reinsert PI-140.

2.Equipment being operated is drawing too much power.

Use a higher capacity inverter or do not use the device.

3.Inverter is too hot (thermal shut down).

Allow inverter to cool. Check for adequate ventila- tion. Reduced the load on the inverter to rated continuous power output.

4.Fuse blows.

A blown fuse is usually caused by reverse polarity or a short circuit within the device being operated. To replace:

Disconnect the device immediately.

Find the source of the problem, and repair it.

Install a new 15-amp fuse. Do not tighten the fuse cap too far; finger tight is sufficient.

Note: Installing a fuse higher than 15-amps may cause damage to the inverter.

5.Inverter may be defective.
