3. Wiring Connections:
   • Connect the incoming power supply (230V, single phase) to the designated terminals within the control box.
   • Connect the 3-wire cable from the submersible pump motor to the corresponding terminals (typically L1, L2, and Ground for power, and a separate terminal for the motor's start winding). Refer to the wiring diagram inside the control box cover for precise connections.

6. Operation

The Franklin Electric 1/2 HP Submersible Water Pump Control Box is designed to automatically manage the starting and running of your 3-wire submersible well pump motor. Once properly installed and connected to a pressure switch or other control device, the control box will engage the motor when water demand is detected and disengage it when the demand is met.
