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.
Be sure not to operate electrical equipment with wet hands. Otherwise, there
is the danger of electric shock.
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.
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.
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.
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.
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.
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.
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.
When the Stop key function is disabled, pressing the Stop key does not stop
the inverter, nor will it reset a trip alarm.
Be sure to provide a separate, hard-wired emergency stop switch when the
application warrants it.
