to make a start or stop. (Refer to section 6.10.4.)
Fig. 3-17: Start and stop of the inverter
When the power supply is 400V class, install a step-down transformer.
Handling of the inverter output side magnetic contactor
Switch the magnetic contactor between the inverter and motor only when both the inverter and
motor are at a stop. When the magnetic contactor is turned on while the inverter is operating,
overcurrent protection of the inverter and such will activate. When an MC is provided for switch-
ing to the commercial power supply, for example, switch it on/off after the inverter and motor
have stopped.
