Were there any diagrams supplied with the units? If so, do you have a way of posting them here?
220V 3ph seems to indicate 220/380V wye to me, if you only have 220V between phases the motor would have to be delta connected (and I mean ungrounded delta).
If you're referring to the generator fed locations you talked about in the other thread I have a strong feeling the easiest thing would be to get a 230/400 or 220/380V 3ph 50Hz generator set and run them as intended.
