Note:
This Solid State starter is wired at the factory for in-delta operation on 6 and 12 lead motors only! If you
have a 9 lead delta motor, you must run it as the “In Line” configuration show on the following page. If you have a
submersible application where only 3 motor leads are brought to the starter, you may elect to run the starter “in line”
also. When running “in line”, the correct size starter must be used. The following pages show how to connect the
starter in the “In Line” configuration.

T6, T4, and T5
