3.6.2Three-Phase Motors - IMPORTANT! BEFORE STARTING THREE-PHASE MOTORS STEPS

1.Prime pump before applying power to avoid damage to the pump and motor.

2.Check the direction of rotation.

Three-phase motors can run in either direction, depending on how they are connected to the power supply. When the three cable leads are first connected to the power supply, there is a 50% chance that the motor will run in the proper direction. To make sure the motor running in the proper direction, carefully follow the next procedure:

Changing Motor Rotation

STEPS

A.Start the pump and note the pressure and flow rate developed at the pump discharge.

B.Stop the pump and interchange any of the two leads (Figure 3.6, Changing Motor Rotation).

C.Start the pump again and re-check the flow rate and pressure.

D.Compare the results observed. The wire connection that yielded the highest pressure and flow rate is the proper con- nection. Interchange the two leads again only if necessary.
