OK, I really do appreciate your time here



That is what I have got, if I can isolate the actual spindle 2230v supply, I can use a 750watt UPS to protect the electronics I guess.

Exactly.

See that switch on the left of the VFD. I believe that is what feeds the VFD with 230V, cause i see no other reason for this in the enclosure or it is for the whole enclosure. Turn it off and see if the BOB is powered, if not, then dont touch it . Just follow the VFD input cable and terminate it where possible at some other connection. Then fit a longer cable and a plug.
If you turn off the switch and the BOB is still powered and the drives are still powered, that means its only for the VFD. Then remove the input cable follow it to some connection and remove it from that side. The fit a new cable with plug directly to the switch.
