I recently received a Marathon Electric phase converster with my CNC machine and I noticed it has a low & a high wiring setup. the markings on the motor are as follows:
Model # AD215TTDR7215AA
HP - 5/1.3
Frame = 215T Type=TDR-BE
DES=B PH=B Code=G
2 speed 2WDG Var Torque
RPM =1765/880 Cycle=60
Serial # 990008
Volts=230 Amps = 13.2/5.4
Max. Amp = 40 Duty=Cont.
Shaft = 77507 Off End Bearing =77505
SF= 1.15

So my question is which setup should I use? the CNC is a Bridgeport Interact 412 and has a 7.5HP motor. The guy I bought it from said I would need leveling capacitors. I do I know if I need them and the proper sizes?

thanks in advance
Ben
