Your within a 5% voltage difference so you definitely have no worries Some machines can start have issues above 10%.Our plants 600v system is at 640v and we have never had any problems.We did call the POCO and found they had run out of taps when we opened the kiosk.All plc's.drives and motors should be happy as long as your within 10%.The machines manual will probably recommend a 5% variance in voltage.Many Canadian built machines get sent to the U.S for the Big Three wired just as you describe.
cheers
