Mounting
About this task:
For wall mounting, select a suitable mounting area away
from windows or doors that open, and avoid areas subject
to high vibrations or excessive moisture. The enclosure
has a hinged cover with a latch. The enclosure offers two
entry points for wiring, one on top and one on bottom,
and one rubber grommet installed in the bottom wiring
hole. The hole provided is for conduit or cable gland
mounting and is 0.86 in. (21.38 mm) in diameter.
To install the sensor, complete the following steps:
1. To open the cover, pull slightly on the latch on the
right side of the enclosure. See Figure 3.
2. To mount the device directly to a flat surface, use
the four integrated mounting holes provided on
each corner of the enclosure using screws, not
provided.
3. Ensure the sensor pods point downwards. See
Figure 3.
4. Route the installation wire through the top or
bottom hole and place the grommet in the unused
hole. See Figure 4 for locations of wiring holes.
5. To wire the connections, see Figure 9 and Figure 10.
6. When you complete the wiring and device setup,
close and latch the cover. The enclosure also
includes a hole for the use of an anti-tamper
device.
