Some of you are right about part of this, but I think nobody hit it on the head. The nine leads are basically the ends of 2 sets of 3 windings. On one set, the other end is tied together. The voltage of this motor is 230/460 or nowadays 240/480 usually. It's easier to draw a picture than explain, but I will try. If you had two y's, with the tail end up, the tail would be 1. Going clockwise, the next leg is 2, then 3, etc., spiraling toward the middle. Like this:

The easiest way to remember how to wire it is series for high voltage, parallel for low voltage. For 460 (or 480) volts, you connect your power leads (L1, L2 & L3 usually) L1 to T1, L2 to T2, and L3 to T3. T4 goes to T7, T5 goes to T8, and T6 goes to T9. For 230 (or 240) volts, you connect L1 to T1 & T7, L2 to T2 & T8, and L3 to T3 & T9. T4, T5 and T6 are then tied together. The "T's" that I reference are the motor leads, which are printed on the lead sometimes with the number. If you look at the picture, you can see what I mean by series for high and parallel for low. The high voltage connection has it's windings in line with the other set. The low voltage connection has the two windings pretty much on top of eachother. And, there you go! Let me know if you have any questions about what I typed.
