When I see three modules labelled with 15 Amp fuse I have doubts that a single phase supply would be enough to activate all three effectively.The L1,L2 and L3 labels are a further hint that 3 phase was the intent.If you have manuals for the machine there might be some advice.What Hp is the spindle?I would think that alone would exceed a single phase circuit.For better guidance,your location and the nature of the normal single phase supplied to the area would help.
