I am currently modernizing an old Otis car that has a 7.5 HP, 208 volt 1200/300 RPM motor. The motor has 12 leads 1 through 6 and 1S through 6S. Am I correct in assuming that the 1-6 leads are the high speed winding and the 1S-6S leads are the low speed? For both sets of leads 4,5and 6 are joined together and 1,2 and 3 go to the respective high and low contactors. I am installing an MCE 4000 controller and my plan is to abandon the 1S-6S leads and use the 1-6 leads to go to the new drive. Can anyone tell me if this is correct?

Thanks
