Vitronics oven corner grounded delta? | 15 November, 2011

I have a new (to me) Vitronics XPM3 oven which we're hooking up. It requires 480V, and I only have real 208V in the facility. I have a transformered up 480 subsystem, but its corner grounded rather than center grounded.

The XPM3 manual suggests that the high leg needs to be connected to L3 on the input, suggesting it is expecting center grounded 480 delta. Does anyone know if it'll be just as happy corner grounded, or if I'm going to have to go through some electrical contortions to get a center grounded service?

Thanks!
