WIRING
• If LCD is present, deactivate the 24 Vac/dc power supply until all connections are made to the device to
prevent electrical shock or equipment damage. Follow proper electrostatic discharge (ESD) handling
procedures when installing the device or equipment damage may occur.
• Use 22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit
with wiring used to supply inductive loads such as motors. Connect the cable shield to ground at the
controller only. Make all connections in accordance with national and local codes.
• Connector layout is shown in Figure 9. The diagram shown includes all options, if an option is not
ordered, the connector will not be present.
WITH PCB
The PCB must be removed from the base to access the mounting
holes. Follow usual anti-static procedures when handling the PCB and
be careful not to touch the sensors. The PCB is removed by pressing
the enclosure base to unsnap the latch near the bottom edge, then
the PCB can be lifted out of the base as shown in Figure 4.
Set the PCB aside until the base is mounted on the wall. For added
protection, place the PCB in the supplied anti-static bag.
Mount the base by screwing it to an electrical box or directly to the
wall as shown in Figure 5.
After the base is screwed to an electrical box or the wall using the appropriate holes, remove the PCB from
the anti-static bag, feed connection wires through center hole and place the top of the PCB into the PCB
holders on the backplate and snap the bottom of the PCB into place as shown in Figure 5.
Make wire connections as per the Wiring Illustrations on pages 2 and 3. Re-install decorative cover by
placing the top of the cover into the cover holder on the top of the backplate and snapping the bottom
into place as shown in Figure 7. Tighten security screw with a screwdriver.
