stopped.
•
Check the power voltage.
•
Check the power input line for discon-
nection.
•
Check the terminal block screws for
looseness.
%U
flashing
Main circuit overvoltage (OV)
The DC voltage of the main circuit
exceeded the overvoltage detection
level when the Inverter was stopped.
•
Check the power voltage.
%h
flashing
