Primary: 480 Delta

Secondary: 240 Delta / 120

This model comes with a center tap (AKA lighting tap) to run 1-phase 120v power off the secondary. The center tap can provide 10% of the total kVA rating without taking away from the overall capacity. 

This transformer can be reverse fed to achieve a step up from 240V to 480V, but the adjustment taps do not work if you do this, and the inrush is greater than using a specially designed step-up transformer.  You can buy a step-up transformer here.
