wires here
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 data - (typically black) EchoConnect wire, the
black lead from the EchoConnect pigtail, and any
continuing EchoConnect (typically black) wire together
and secure with a wire nut.
c: Repeat the above steps for the data + (typically white)
EchoConnect wire and the ESD ground wire.
Orient the smooth 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.
Secure the mounting plate to the junction box using the
screws provided (both short and long screws are provided for
convenience).
Strip each wire 5/16" (8mm) and terminate the EchoConnect
(white and black wires) and the ground wire (green/yellow) to
the EchoConnect terminal block located on the sensor
controller. Torque each termination to 3.1-3.5 in-lb.
a: Terminate the white incoming wire to the data +
terminal.
b: Terminate the black incoming wire to the data - terminal.
c: Terminate the green/yellow (ground) wire to the ground
terminal.
