Thank you for posting your question here on Fixya.com.
I am not sure what you mean by "center wire". For 230V single phase you should have 2 hot line leads (115V each) and a ground wire. Set the motor leads as the nameplate shows for the high voltage connection and attach your line leads where the two lines are indicated. If you have a 3+Grd wire drop DO NOT connect the neutral, insulate it and leave it unconnected. It will not matter which line lead connects to which motor line wire as far as rotation direction. To change rotation, if the motor allows it, you reverse the start winding leads as directed on your nameplate.
