Cause : Power Supply Overvoltage comes when the input power supply voltage became equal to or higher than the Input Power Supply Overvoltage Detection Level.

1. 200 V Class: Approximately 277 Vac
2. 400 V Class: Approximately 554 Vac

  • The input power supply voltage is too high.
  • Reduce the voltage to within the range in the power supply specifications.
