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.

    Yeah most of the VSDS are within electrical panels and the incoming and outgoing Swas Are all connected together with internal cores terminated to a din rail. So one earth run to the chassis from the earth terminal is substantial?
