Cause : Inrush current limit circuit fault comes when the inverter trips when the resistor of the inrush current limit circuit is overheated. The inrush current limit circuit failure.

1. Check that frequent power ON/OFF is not repeated.
2. Check if the input side fuse (5A) in the power supply circuit of the inrush current limit circuit contactor (FR-F840-
   03250(132K) or higher) is blown
3. Check that the power supply circuit of inrush current limit circuit contactor is not damaged.
