65-2301RKSS Toxic Detector • 9
5.
Connect the two wires to the detector using the terminal block.
CAUTION:
If using shielded cable, leave the drain wire insulated and disconnected at the detector. You will
connect the opposite end of the cable’s drain wire at the controller.
6.
Secure the junction box cover to the junction box.
7.
Route the cable or wires leading from the toxic detector through one of the conduit hubs at the
controller housing. Use appropriate conduit fittings and construction technique for the
environmental rating of the controller. RKI controllers are typically rated NEMA 4X.
CAUTION:
Do not route power and detector wiring through the same conduit hub. The power cable may
disrupt the transmission of the detector signal to the controller.
8.
Connect the wires to the applicable controller terminal strip. See the controller operator’s manual
and the controller’s detector head specification sheet for the 65-2301RKSS detector.

9.
If using shielded cable, connect the cable’s drain wire to an available chassis ground at the
controller. RKI controllers typically have a ground stud that is a convenient grounding location.
10. Reinstall the junction box cover.
