INSTALLATION (continued) Step Six
4. Mechanical connection to conduit: All wiring between a controller and sensors should be in conduit.
The power entrance of the controller is a standard ½” NPT female fitting that will attach to standard
electrical conduit, either plastic or metal, as specified by local codes. Keep in mind that the housing
may have to be unscrewed from the sensor for periodic cleaning of the sensor. For this reason the use
of flexible conduit, providing enough slack for easy access is recommended.
5. Connect the extension wiring:
Before making connections, make sure all power to the system (controller, motor, valve, alarm, etc.)
is OFF with a safety lockout on the circuit breaker.
a. The extension wiring to controller should take into account long cable runs. If the run is long, it
may need to be a slightly thicker gauge so the series resistance is kelp within allowable limits.
b. Thread the extension wiring through the power conduit entrance of the housing.
c. Strip ¼” of the insulation from the ends of the wires.
d. Loosen the appropriate terminal screws. Insert the extension wires into the corresponding
terminals, matching the sensor wires.
e. Tighten the terminal screws.
f. Return the wire protector to its location and restore the final screw which holds the wire
protected and PCB in its place.
g. Replace the cap.
Note: In some cases, additional user‐provided components may need to be attached to the terminals. If
so, make sure that both wires and/or components entering the terminal are secure after the screws are
tightened.
Note: Always tighten the controller from the wrench flat located on the
swivel base. Never tighten from the body of the controller.
