    Lenze's new VFD at our paper plant trips on earth fault immediately on receiving a start command. It happens even when no motor and leads are connected. What could be the reason for tripping? Would adding a ground fault sensor help?

    The drive probably has Internal EMC filter which will need disconnecting. Probably Screw on the side but the manual should tell you.

    there are 2 options not to open it.
    1 use higher protection current 500mA
    2 connect before protection device if possible

    reason as jazzcnc mentioned EMC filter
