I'm powering up a EMCO PC 155 Turn. I have a 3 phase converter. Emco Specs. voltage not to exceed 10%. Current voltage 460V 15% above Spec. on high leg. My question is has anyone out there ever hooked up or currently running a EMCO PC 155 with voltage over Specs? Emco uses the neutral for the 230V. That one leg could bite me because it is 260V to neutral. The 400V reference to high leg is 460V. Not willing to start burning up components. My Miyano, Centurian and Hardinge/Omniturn run great. They don't use neutral/ground reference for voltage like EMCO.
