Echo Relay Panel Feedthrough Installation Manual
Step 1:
Pull Belden 8471 (or an equal type) control wiring and a 14 AWG (2.5mm
2
) ground into
the Echo Relay Panel through conduit.
Step 2:
Strip 5/16” (8mm) of insulation from the ends of each wire pair.
Step 3:
Remove the EchoConnect connector (J6) from the termination I/O board.
Step 4:
Loosen the terminal screws for as many wire pairs as you are terminating.
Step 5:
Insert each white wire (typical) from the pairs into the “+” terminal on the connector and
tighten the screws firmly to secure the wire into the connector.
Step 6:
Insert each black wire (typical) from the pairs into the “-” terminal on the connector and
tighten the screws firmly to secure the wire into the connector.
Step 7:
The 14 AWG (2.5mm
2
) ground wire can terminate in one of three ways:
• Connected between stations using WAGO Lever-Lock connectors (ETC part
number J4629).
• Grounded to metal conduit.
• If grounded metal conduit is not installed, connect the ground wire to the Echo
Relay Panel ground bus (same as the loads are grounded) and to the green/yellow
striped wire connected to the Echo Preset Station using a WAGO Lever-Lock
connector. Reference the related station installation instructions for details.
Step 8:
Replace the EchoConnect connector to J6 on the termination I/O board.
Using Category 5 Cable
When using EchoConnect over Cat5 cable, the bus uses all pairs in the Cat5 cable plus a
separate ESD ground wire. the combined length of an EchoConnect wire run using Cat5
cable cannot exceed 1000’ (300m).
To terminate Category 5 cable to the Echo Relay Panel, you will need to use a Unison
EchoConnect Cat5 ERP Termination Kit, ETC part# 7186A1208. For instructions on installing
this kit, please reference the
Echo Relay Panel Cat5 Termination Kit Installation Guide
. ETC
manuals can be downloaded at

.
Note:
If you are using Cat5 (or Cat5e) wiring, an external Echo Cat5 Termination Box is
required. Contact ETC for ordering details. Control wiring instructions between the
termination box and this Echo Relay Panel will be provided with the Cat5 Termination
Box installation instructions. For restrictions while using
