VFD Cable and 2.2kw spindle wiring

So Jazz, where do you connect the shield to?

This is how I'd do it... though there are other variations you could do...

I Always take shield back to the Star point like you have drawn for every shielded cable. And in the case of VFD's I take to the VFD sheild point BUT only if the VFD picks up it's earth from main star point. If not then I take separate wire back to star point.!

Actually On reflection now knowing Stephens using MDF for a frame then yes I probably would run an earth from spindle but back to the star point like you have drawn NOT the VFD unless VFD picks it's earth from the star point.
