FAULT DESCRIPTIONS
FAULT CLEARING
Once the cause of the fault condition has been corrected, the fault can be cleared with the on/off switch.
First turn the switch to the off position and then back to the on position in order to reset the inverter. If
a fault is sustained the inverter will not reset, and will continue to report the fault. Once the fault clears,
the red LED will turn off and the yellow LED will remain lit.
FAULT DESCRIPTIONS AND TROUBLESHOOTING
(1) IPM Over Current Fault (0x0002)

Short circuit in output AC line.
•
Low supply voltage to IPM control circuit.
•
