Arburg Moulding Machine Supply Spec

[Mtronics]

Does anyone know how to spec a supply for an Arburg 270c 400 100?it has a total 29kW load, 55 Amps(Both Stated on Nameplate), im wondering is this spread across three phases? supply 400Volts ac. 16 sq mm cable.on the spec sheet it says electrical connection prefused 63 amps, but that its evenly spread across phases.does this mean its 29000/400*root3 for the amps per phase?

Power factor < 1 might also be a solution to the mystery. Especially as I'd expect that the main load of an injection moulding machine is an an induction motor.
