My apologies for the delay, was trying to get a picture of the jumper.
The manual shows this:
1.Live to Terminal 1 on top of starter
2. Neutral to terminal 5 on top of starter
3. You connect a wire as a jumper from Terminal 2 on the overload
and run up to Terminal 3 on the starter
4. Then connect the motor Live to Terminal 4 on the overload
5. Motor neutral to Terminal 6 on overload.
What you are doing, since it is a single phase motor, is to have the power
run through the overload on the unused leg to insure the overload
sees 3 phases of amperage to operate by and not just 2 or else it would
not sense properly to trip out.
