5.
Using two no. 6-32 x 1 mounting screws (provided with the sensor) secure the sensor to the
electrical box.
6.
Use 20 gage wire to connect the sensor to the controller. The wire is suitable for distances of
up to 500 ft. Use a three-conductor shielded cable for the sensor and setpoint adjustment
connections. The standard CCN communication cable can be used. If the setpoint adjustment
(slidebar) is not required, then an unshielded, 19 or 20 gage, two-conductor, twisted pair
cable can be used.
The CCN network service jack requires a separate, shielded CCN communication cable.
Always use separate cables for CCN communication and sensor wiring. (Refer to Figure 2 or
3 for wire terminations.)
7.
Replace the cover by inserting the cover at the top of the mounting plate first, then swing the
cover down over the lower portion. Rotate the two Allen head screws counterclockwise until
the cover is secured to the mounting plate and located in position.
