Thanks Guys,
As a "Conversion", I am hoping to keep it all inside the original box.
This would keep the neat and tidy appearance and go a long way to controlling the dust ingression.
Do you think the EMI filter inline on the AC Mains lines, won't be enough? (I am a humongous fan of over engineering!)
There is a good sized ferrite core on the output wires of the VFD & a smaller one for the Water-pump (direct AC).
Working with the fully enclosed path for now, would an IDC ribbon cable be suitable to extent to the front panel for the MPG Pendant?
