CAUTION: Leave the cable drain (shield) wire insulated and disconnected at the transmitter. You
will connect the opposite end of the cable’s drain wire at the controller.
9. Secure the junction box cover to the junction box.
10. Route the cable or wires leading from the oxygen transmitter through one of the
conduit hubs at the controller.
CAUTION: Do not route power and transmitter wiring through the same conduit hub. The
power cable may disrupt the transmission of the transmitter signal to the
controller.
11. Connect the wires to the applicable transmitter terminal strip at the controller as
shown in Figure 3.
