1. Pull the Belden 8471 (or equivalent) and 2.5 mm
wire to the mounting location. Strip each wire 11 mm (7/16 in).
2. Temporarily remove the sensor cover to gain access to the
configuration switches and mounting access holes. Hold the sensor
in one hand while gently twisting the cover clockwise.
3. Prepare the ceiling tile.
a. Align the flat side of the sensor to the finished side of the
ceiling tile and mark the center access hole for wire pass-
through.
b. Remove the ceiling tile material from marked access hole.
c. Pull all incoming wires through the access holes of the ceiling
tile.
4. Secure the sensor in place.
a. Insert the soft ceiling tile adapters through the provided
pinholes on the sensor, one set located on each side of the
sensor near the mounting keyholes.
b. Push the adapters through the ceiling tile, and then bend each
tine over in opposite directions for a secure fit.
5. Connect the EchoConnect wires from the sensor to the installed
wires.
a. Connect the data– EchoConnect wire (black) from sensor to the
incoming data– EchoConnect (typically black) wire using a
WAGO wire termination connector (provided).
b. Repeat the above step for the data+ EchoConnect wires (white),
and again for the ESD ground wires (green/yellow). Use a new
WAGO connector for each termination type.
