My recollection is the Mazak is 480.

I recall there is a 480 panel and a 240 panel.  I think Roland 
has a dry transformer inside the building to get the 240.  The 
240 may not be available from the bus duct, only 480.

A 5 KVA single-phase transformer isn't all that big, but in 3 
phase they start to get pretty heavy to lug around.

I have a 2 KVA single-phase step-down transformer.  Would that 
be needed?  I can bring it along.
