400V two phase
Bryan, after reading this brochure once again for the ummmpth time, I have to correct something I posted previously regarding the correct voltages.
These machines are either suited for 400V or 240V, both TWO phase or one phase circuits. Check the specifications on page 6: for instance 415V/2N/50 actually means "415 Volts, 2 live plus 1 neutral wires, 50Hz", and 240V/1N/50 means "240 Volts, 1 live wire plus 1 neutral wire, 50Hz. Of course "your" machines are special order 60Hz. These are not three phase machines.
I hope this helps on your decision.
