Ok that is easy to do, I have some huge stranded ground wire from a CT
scanner... I've attached my updated drawing of the VFD panel.
The monitor can only run on 120v so it is necessary to transform from
240 to 120 for the PC and monitor.

Not sure how I might isolate the VFD from the chassis at this moment.
Well I could machine some delrin standoffs... I have a machine shop.
No problem. If you ensure that the chassis connection is firm and
electrically sound, then you just ommit the earth wire (my comment in
the drawing).
One more comment. If you are unsure that the internal earth/chassis
connection in the VFD controller holds, then you usually see a
connection as seen in the attached image. A short thick wire is run from
the earth screw connection to one of the chassis mounting bolts.
