Cautions
and
Warnings
!WARNING Turn ON the input power supply only after mounting the front cover, terminal covers,
bottom cover, Digital Operator, and optional items. Not doing so may result in electri-
cal shock.
!WARNING Do not remove the front cover, terminal covers, bottom cover, Digital Operator, or
optional items while the power is being supplied. Not doing so may result in electrical
shock or damage to the product.
!WARNING Do not operate the Digital Operator or switches with wet hands. Doing so may result in
electrical shock.
!WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
!WARNING Do not come close to the machine when using the error retry function because the
machine may abruptly start when stopped by an alarm. Doing so may result in injury.
!WARNING Do not come close to the machine immediately after resetting momentary power inter-
ruption to avoid an unexpected restart (if operation is set to be continued in the pro-
cessing selection function after momentary power interruption is rest). Doing so may
result in injury.
!WARNING Provide a separate emergency stop switch because the STOP Key on the Digital
Operator is valid only when function settings are performed. Not doing so may result
in injury.
!WARNING Be sure to confirm that the RUN signal is turned OFF before turning ON the power
supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so while
the RUN signal is turned ON may result in injury.
!Caution Be sure to confirm permissible ranges of motors and machines before operation
because the Inverter speed can be easily changed from low to high. Not doing so may
result in damage to the product.
!Caution Provide a separate holding brake when necessary. Not doing so may result in injury.
!Caution Do not perform a signal check during operation. Doing so may result in injury or dam-
age to the product.

product.
