NOTE
• When starting up the system operation, press the RESET switch to reset the safety stop function first,
then turn ON the START switch to run the motor.
• In the above configuration, after resetting the of emergency stop button, the inverter will be in the safe-
state until the RESET switch is pressed.
Caution
 To prevent restart of the inverter when the power is restored after a power failure, 3-wire connection
is recommended for the START/STOP control. In case of 2-wire connection and using latching type
switch to short between STF and SD/PC for starting, ensure the compliance with safety standards for
the restarting when the inverter power is restored after a power failure.
