WARNING: Be sure to turn on the input power supply after closing
the front case. While being energized, be sure not to open the front
case. Otherwise, there is the danger of electric shock.
WARNING: Be sure not to operate the switches 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 during the trip stop. Do not approach 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 command to operate 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 Key separately from the
emergency stop. Otherwise, it may cause injury to personnel.
WARNING: After the operation command is given, if the alarm
reset is conducted, it will restart suddenly. Be sure to set the alarm
reset after verifying the operation 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: When the power is turned on when the running
command is already active, the motor will suddenly start rotation
and is dangerous. Before turning the power on, confirm that the
running command is not enabled.
WARNING: When the Stop key function is disabled, pressing the
Stop key does not cancel the stop and trip.
WARNING: Be sure to provide a separate, hard-wired emergency
stop switch. When the operation command source is a digital opera-
tor, this selection is ineffective.
WARNING: 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.
