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.
. 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.
