Most of 50Hz lands are 400V(3-phase)/230V(single phase), and usually TN-C/S grounding or in fewer cases TT grounding.
You need to make sure that it is compatible. In most Europe, three phase is preferred, almost obligatory in industrial plants.
When my company supplies equipment, if it is not specifically required by customer, the electrical enclosure will have on input 3 phases and Protective Earth, without Neutral and there will be 400V/230V transformer for control voltage, so there will be no way to connect single phase motor.
