    Tips: How to connect the inverter with star delta starter?

    The original motor line is disconnected from the power frequency power supply, directly connected to the output of the inverter, and the auxiliary contact of the contactor switched to the delta is used as the starting signal of the inverter to complete the transformation of pure inverter control.

    If power/variable frequency switching is required, an interlocked switching contactor or a manual air switch should be added between the original power frequency power supply and the output of the inverter.
