2 – If this connection of the motor armature leads results
in motor rotation opposite of what is required,
reverse the A1 and A2 lead connections at the
motor.
3 – Connect Drive Terminal A2/S1 or S2 to Motor
Terminal A2.

9. Make certain power is turned off and locked out.
10. Switch armature leads connected A1 (+) and 45 ( – ). If it is
inconvenient to switch the armature leads, the field leads
connected at F1 and F2 may be switched instead on a straight
shunt motor only. Be sure to document the final connection.
11. Apply power to the Drive.
12. Repeat steps 6 and 7 and verify that the motor rotation is correct.
NOTE: If both the field and armature connections are reversed no
change in rotation direction will occur.
