14.9 Wiring and Mounting a ZS Sensor
WARNING:
The Rnet cable is wired to the controller. Before wiring
and mounting sensor, the shield wire and the ground
wire should be inserted into the controller’s GND
terminal.
1. Turn off the controller’s power.
2. Pull the backplate off the ZS Sensor. You may need to turn the setscrews in the bottom of the sensor clockwise until you can remove the
backplate.
3. Pull the Rnet communication cable through the slit in the insulated backing material.
3.30 in.
(8.38 cm)

4. Use 2 screws to mount the backplate to the wall or outlet box.
5. Partially cut, then bend and pull off the outer jacket of the Rnet cable(s). Do not nick the inner insulation (Fig. 14).

6. Strip about .25 inch (.6 cm) of the inner insulation from each wire.
7. If wiring 1 cable to the ZS Sensor, cut the shield wire off at the outer jacket, then wrap the cable with tape at the outer jacket to cover the end
of the shield wire.
If wiring 2 cables in a daisy-chain con
fi
guration, twist together the shield wires, then wrap the shield wires with tape.
8. Insert the other 4 wires into the ZS Sensor’s screw terminal connector. If wiring 2 cables, insert like-colored wires into each terminal.

CAUTION:
Allow no more than .06 inch (1.5 mm) bare
communication wire to protrude. If bare
communication wire contacts the cable’s foil shield,
shield wire, or a metal surface other than the terminal
block, the device may not communicate correctly.

9. Attach the sensor’s cover and circuit board to the mounted backplate, inserting the top
fi
rst.
10. Turn the setscrews one full turn counterclockwise so that the cover cannot be removed.
11. Turn on the controller’s power.
Use the same polarity throughout the Rnet.
