What to do if my Fuji Electric FRENIC-Multi Inverter shows an enable circuit failure?
- MMelissa LucasJul 30, 2025
If your Fuji Electric Inverter shows an enable circuit failure, first ensure the interface PCB is correctly mounted. If that's not the issue, check that the safety switch output levels (EN1/EN2) are consistent (both High/High or Low/Low). Power cycle the inverter to clear the alarm. If the problem persists and a single enable circuit failure is detected, the inverter requires repair; contact your Fuji Electric representative, as the 'Reset alarm' terminal command RST won't resolve it.
