Be sure not to operate electrical equipment with wet hands. Otherwise, there
is the danger of electric shock................................................................ ... 166
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. .........................................................................................................166
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. .............................................. 166
If the power supply is cut OFF for a short period of time, the inverter may
restart operating 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. .....................................................................................166
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. .......................................................................... 166
WARNING: During a trip event, if the alarm reset is applied and the Run com-
mand 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. .......................................................................... 166
Be sure not to touch the inside of the energized inverter or to put any conduc-
tive object into it. Otherwise, there is a danger of electric shock and/or fire.
.................................................................................................................... 166
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, con-
firm that the RUN command is not present. ...............................................166
When the Stop key function is disabled, pressing the Stop key does not stop
the inverter, nor will it reset a trip alarm. .................................................... 166
Be sure to provide a separate, hard-wired emergency stop switch when the
application warrants it. ................................................................................166
If the power is turned ON and the Run command is already active, the motor
starts rotation and is dangerous! Before turning power ON, confirm that the
Run command is not active. .......................................................................179
After the Reset command is given and the alarm reset occurs, the motor will
restart suddenly if the Run command is already active. Be sure to set the
alarm reset after verifying that the Run command is OFF to prevent injury to
personnel. .................................................................................................. 184
