I just bought a used Italian printing machine. Manufacturer says 400 volt monophase. Electric drawing shows all power takeoffs are phase to neutral at 230 Volt.
Existing plug on machine reads 250 volt 3 phase 20 amp. This was working in Ontario Canada. How do we wire this machine up?

I've got my answer, thanks.

Needed a single phase transformer to provide an isolated neutral.
