*1 This magnetic contactor is provided to prevent an automatic restart when power is restored after a power failure. Use the start
signal (ON or OFF of STF) to make a start or stop.
*2 When the power supply is 400V class, install a step-down transformer.
*3 Set [Pr. 75 = 1] "Reset can be made only when a fault occurs" to disable resetting the inverter during normal operation.
(If the inverter is reset during normal operation, the motor coasts to a stop. This setting is made to prevent the inverter from
resulting in an alarm if the motor is still coasting when the inverter has returned from the reset status.)
