Cause : 24 V external power supply operation comes when the main circuit power supply is off and the 24 V external power supply is being input.
- Power is supplied from a 24 V external power supply.
- Turning ON the power supply (main circuit) of the inverter clears the indication.
- If the indication is still displayed after turning ON of the power supply (main circuit) of the inverter, the power supply voltage may be low, or the jumper between the terminals P/+ and P1 may be disconnected.
