Page 11: Wiring The Toxic Gas Transmitter
CAUTION:Do not route power and transmitter wiring through the same controller conduit hub. The power cable may disrupt the transmission of the transmitter signal to the controller. 11. Connect the wires to the applicable detector/transmitter terminal strip at the controller as shown in Figure 5. 65-2340RK Toxic Gas Transmitter • 11... - Page 12 12. If shielded cable is used, connect the cable’s drain wire to an available chassis (earth) ground at the controller. RKI controllers typically have a ground stud that can be used to ground the cable’s drain wire. 12 • 65-2340RK Toxic Gas Transmitter...
