wires here
1. Pull the Belden 8471 (or
equivalent) and one 2.5 mm
2
(14 AWG) ground wire to the
mounting location (junction
box or finished surface).
2. If you are installing the
sensor in series with other
sensors or stations
(continuing the data run),
use the provided
EchoConnect and
ESD ground wire pigtails.
Termination connectors are
not provided. If you are not continuing the data run, direct
termination to the sensor controller is recommended, skip this step
and proceed to step 3.
a. Strip each wire to the appropriate length, depending on the wire
nut or other termination used (wire nuts are not provided).
b. Twist the incoming data - EchoConnect wire (typically black) and
the data - wire (black) from the EchoConnect pigtail as well as any
continuing data - EchoConnect wire together and secure with a
wire nut.
c. Repeat the above step for the data + EchoConnect wire (typically
white) and for the ESD ground wire (typically green/yellow), using
a new wire nut for each termination type.
3. Orient the flat side of the mounting plate to the junction box and pull
the EchoConnect wires or terminated pigtail from the junction box
through the provided holes near the center of the mounting plate.
4. Secure the mounting plate to the junction box using the screws
provided.
5. Terminate EchoConnect and ESD ground wires to the terminal block
on the sensor controller. Torque each terminal 3.1-3.5 in-lb.
a. Strip each wire 8 mm (5/16 in).
b. Insert the data + (typically white) EchoConnect wire into the
data + terminal and secure.
c. Insert the data - (typically black) EchoConnect wire to the data -
terminal and secure.
d. Insert the green/yellow (ground) wire into the ground terminal
and secure.
