Connect Wiring
1. Pull all required wiring into the back box. As needed, pull an
additional ESD ground wire (required only when the Interface is not
installed in grounded metal conduit).
2. Terminate the ESD ground wire pigtail.
a. Strip 11 mm (0.4 in) of insulation from the ends of the ESD ground
wire pigtail provided in the termination supplies and the incoming
ground wire.
b. Use one WAGO 221 Series LEVER-NUTS
®
(provided) to connect the
ESD ground pigtail and the incoming ground. Installations using
grounded metal conduit, connect the ground pigtail to the metal
back box ground location.
c. Install the ESD ground wire pigtail FASTON connector to the
mating receptacle on the Interface electronics.
3. Terminate EchoConnect wires. EchoConnect is topology free, you
may install the wires in any combination of bus, star, loop, or home-
run.
a. Strip 11 mm (0.4 in) from the ends of each EchoConnect power
pigtail wire (black and white wire pair), provided in the
termination supplies, and the installed control wires.
b. Use the WAGO connectors (provided) to connect the EchoConnect
pigtail wires and the installed Belden 8471 control wires. One
WAGO should be used for the white wire pair (data +) and one for
the black wire pair (data -). Open the terminal levers on the WAGO
connector and insert the installed Belden 8471 wire and the lead
from the power pigtail into the terminals, and then close the
levers.
c. Install the two-pin connector from the EchoConnect pigtail to the
mating receptacle on the station electronics.
