E/One Grinder Pumps: Wiring a Buck Boost Transformer for use with an E/One Station

E/One pumps are rated for 240V. They require 240V +/- 10% or (216V - 264V) and will not run reliably on 208V.
In situations where the available power supply is 480 wye/277 volts, 60 Hz, 3 phase, a Buck Boost transformer is required to boost power up 32V to 240V.

pardon my ignorance...if i have 277V coming out of the wall, but i want to power up a parking lot fixture in my lab (for a thermal test) rated at 480V (white, black, green)...what transformer would you recommend?

No neutral? Neutral no grounded?
