Thor,
The leads are called "T" leads. You connect them to a 3 wire supply (unless you are counting your equipment ground).
480 volt supply
Phase A-B-C = leads 1-2-3
Splice together 4-7, 5-8, 6-9
That is the standard, you should see a wiring diagram on the side of your motor to confirm this, and give you other connection for multi-voltages if it is designed for it.
