1. Pull the Belden 8471 (or equivalent) and 2.5 mm
2
(14 AWG) ) ground
wire to the mounting location and 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 the sensor wires through the access holes to the unfinished
side 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 on the unfinished
side of the ceiling tile.
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 wire (white)
and for the ESD ground wire (typically green/yellow), using a new
WAGO connector for each termination type.
