Wiring the Oxygen Detector to a Controller
WARNING: Always verify that the power to the controller is off before you make
wiring connections.
1. Turn off the controller.
2. Turn off or unplug incoming power to the controller.
3. If the detector is mounted remotely from a controller using the junction box, proceed
to step 4.
If the detector is mounted directly to a controller, it is normally factory wired. Confirm
that the detector’s white and green wires are connected to the appropriate controller
detector terminals and skip to “Start Up” on page 5. See Figure 2, the controller
operator’s manual, and the controller’s detector head specification sheet for the
65-2511RK detector for the wiring connections.
4. Remove the junction box cover.
5. Guide a two-conductor, shielded cable or two wires in conduit through the top
conduit hub of the junction box. Use appropriate conduit fittings and construction
technique for the environmental rating of the junction box. The junction box is rated
NEMA 4X.
