NOTE: DO NOT USE ALUMINUM WIRE.
Attention: To meet full compliance with FCC Part 15
Subpart B and CENELEC EN 55011, shielded motor
cable should be used between the drive motor output and
the motor. Using shielded cable provides the maximum
filtering to reduce radiated & conductive emissions which
can cause interference with other devices.
CONTROLLER INSTALLATION PROCEDURE
1. Disconnect electrical power at the main breaker
2. Drain the system (if applicable)
3. Install pressure switch or transducer - the pressure switch
or transducer has a 1/4 - 18 National Pipe Thread (NPT)
connection.
4. Remove the controller cover by removing the lid screws.
Attach the unit to the wall using mounting screws (not
included).
Wiring Connections
1. Verify that the power has been shut off at the main
breaker.
2. Verify that the dedicated branch circuit for the controller is
equipped with the correct rating of circuit breaker.
3. Remove the controller lid.

4. Feed the motor and ground leads thought the appropriate
knockout on the bottom right side of the unit and connect
them to the terminal block positions. Submersible
3-Phase or 3-Wire 1-Ph motors: follow colors as marked:
Red (RED), Black (BLK), Yellow (YEL) and (W).
Submersible 3-Phase or 3-Wire 1-Ph motors: follow
colors as marked: Red to RED, Black to BLK, Yellow

1-Ph motors: Connect motor leads to BLK, YEL and
Green Ground wire (W).
Above Ground Motor (3-Phase Only): L1 to RED,
L2 to BLK, L3 to YEL and Green Ground wire (W)
Verify motor rotation to avoid damage
to pump & motor.

- For Switch (VS Drive Kit): Connect the red and black
lead wires to the terminals marked "S1" and "S2"
(interchangeable) on the display board terminal strip with
a small screwdriver (provided).
