My "new" mill has a two speed three phase motor. The wiring to the machine is 5 wire, with a neutral. The plug on the side of my old Transwave static converter has 4 wires.
Now the plug isn't a Transwave fitting (I put it on) so don't blame them but how should I sort this one out? Will there be a netrual in a static converter? If so where or do I just ignore it?
