Welcome. My name is ***** ***** would be glad to assist.
Are you just wanting to reverse the motor and run one direction all the time?
or set the motor for reversing switch where you change it constantly, like on a lathe?
Post how you have it wired now:
Black to P1
White to ?
Leads that are tied together?
Let me know and we can continue,
Thanks

reverse one time
Expert:  AssuredElectrical replied 1 year ago.
Ok, thanks.
Let me post all the wiring below.
First will be for 120 volts and the second for 230 volts.
There are 2 ways to wire on each one, so pick the one you need, this way you can print them out and use for the future.
For 120 volts operation see the options below:
First Clockwise
Black from breaker to P1
White from neutral bar to T2,T4 and T8
P2,T3 and T5 all joined together
Second Counter Clockwise
Black from breaker to P1
White from neutral bar to T2,T4 and T5
P2,T3 and T8 all joined together
If you notice, the difference in the two, is the location of the
T5 and T8 motor leads.
Those are the leads that change the motors direction.
This is most often the case.

If you want to operate the motor at 230 volts see the below options:
First Clockwise
Black from breaker to P1
White from breaker to T4 and T8
T3,T5 and T2 all joined together
P2 is capped off, not used
Second Counter Clockwise
Black from breaker to P1
White from breaker to T4 and T5
T3,T8 and T2 all joined together
P2 is capped off, not used
Let me know anything further needed, just reply.
Thanks
