Operating
Procedures
WARNING: Be sure to turn ON the input power supply only after closing the front case. While
the inverter is energized, be sure not to open the front case. Otherwise, there is the danger of
electric shock.
WARNING: Be sure not to operate electrical equipment with wet hands. Otherwise, there is
the danger of electric shock.
WARNING: While the inverter is energized, be sure not to touch the inverter terminals even
when the motor is stopped. Otherwise, there is the danger of electric shock.
WARNING: If the Retry Mode is selected, the motor may suddenly restart after a trip stop. Be
sure to stop the inverter before approaching the machine (be sure to design the machine so that
safety for personnel is secure even if it restarts.) Otherwise, it may cause injury to personnel.
WARNING: If the power supply is cut OFF for a short period of time, the inverter may restart
operation after the power supply recovers if the Run command is active. If a restart may pose
danger to personnel, so be sure to use a lock-out circuit so that it will not restart after power
recovery. Otherwise, it may cause injury to personnel.
WARNING: The Stop Key is effective only when the Stop function is enabled. Be sure to
enable the Stop Key separately from the emergency stop. Otherwise, it may cause injury to
personnel.
WARNING: During a trip event, if the alarm reset is applied and the Run command is present,
the inverter will automatically restart. Be sure to apply the alarm reset only after verifying the
Run command is OFF. Otherwise, it may cause injury to personnel.
WARNING: Be sure not to touch the inside of the energized inverter or to put any conductive
object into it. Otherwise, there is a danger of electric shock and/or fire.
WARNING: If power is turned ON when the Run command is already active, the motor will
automatically start and injury may result. Before turning ON the power, confirm that the RUN
command is not present.
WARNING: When the Stop key function is disabled, pressing the Stop key does not stop the
inverter, nor will it reset a trip alarm.
WARNING: Be sure to provide a separate, hard-wired emergency stop switch when the appli-
cation warrants it.
