VSD earthing

MrJack96
Hi I’m abit confused as to VSD earthing. I know they carry high leakage currents but have seen invertors not being directly earthed at the chassis of the VSD as the incoming earth and out going earth are connected elsewhere in the panel is there any benefits or problems with doing this? I know in BS7671 it states about having two PE for equipment with high leakage currents just trying to understand if it related to VSDS and the chassis needing to be earthed(with two conductors/or not) 


thanks for your help guys.

    There are also cases where the VSD is supplied via an isolating transformer, to limit the effect of the high protective conductor currents to the outgoing side, effectively the drive and motor, but in that case usually the incoming and outgoing PE are bonded together, and to the isolating transformer outgoing Neutral.
