must be used to connect the controller to the pump
starter circuit.
1. Route a wire pair from the pump relay into the
controller housing.
2. Connect one wire to the terminal labeled COM (8).
Connect the remaining wire to the terminal labeled

Make sure the power source is OFF prior to con-
necting the controller.
1. Route the power and equipment ground wires from
the power source, through the conduit and into the
controller transformer compartment.
