11 Wiring and Mounting
The Rnet cable is wired to the controller at the Rnet connector. The shield wire
(if available) and the ground wire should be inserted into the controller’s GND
terminal.
1.
Turn off the controller’s power.
2.
Pull the back plate off the ZS Sensor. You may need to turn the setscrews in
the bottom of the sensor clockwise until you can remove the back plate.
3.
Pull the Rnet communication cable through the slit in the insulated backing
material.(See Figure 9)
