Overview

The Unison® Heritage Button Station connects to the LinkConnect station
communication bus. LinkConnect is based on Echelon® LonWorks™ with
LinkPower bidirectional protocol, and uses one pair of wires (data+, data–).

LinkPower is topology free and polarity independent; you can install your
LinkPower data runs in any desired combination of bus, star, loop, and home-run.
ETC recommends using Belden 8471 (or approved equal) wire. The total
combined length of a LinkPower wire run may not exceed 1,640 feet (500m), with
a maximum distance of 1,312 feet (400m) between any two devices. The Heritage
Button Station may be installed into an industry standard single gang backbox
(provided by others) or a surface mounted backbox (sold separately and available
from ETC).

All control wiring should be installed and terminated by a qualified installer and
should follow standard wiring installation practices. Leave approximately 10 inches
(254mm) of wiring in the backbox for connection and to allow slack for future
service needs.

Installing the Heritage Button Station

Installation should follow local codes
and standard practices. The backbox
should be installed square for best
results. Ensure that the backbox is clean
and free of obstructions and that all
wiring is installed correctly.

Heritage stations ship with a termination
kit containing a LinkPower pigtail, a
ground wire pigtail, spacers, and all
required connectors for installation.

Connecting the Wiring

Step 1: Pull all required wiring to the backbox.
Step 2: Terminate and connect LinkPower. LinkPower is topology free and

polarity independent. You may install LinkPower in any combination
of bus, loop, star, or home-run.

a: Locate the LinkPower pigtail and two WAGO CAGE CLAMP

®

connectors from the termination kit.

b: Strip 3/8” (9-10mm) from the ends of each LinkPower wire

(both pigtail and installed LinkPower wire).

c: Use the WAGO CAGE CLAMP connector to connect the

installed control wire to the connectorized pigtail wires
provided. Open the terminal levers on the WAGO connector
and insert the installed (typically black) Belden 8471
LinkPower wire and the black lead from the LinkPower pigtail

into the terminals.
d: Close the levers onto the wires.
e: Repeat for the installed (typically white) Belden 8471

LinkPower wire and remaining pigtail wire using a new WAGO

connector.
f: Install the LinkPower connector onto the Heritage Button

Station control board.

Step 3: Terminate the ESD drain (ground)

wire. This connection is required
only when the control cable is not
installed in grounded metal conduit.
a: Locate the ground wire pigtail

and one WAGO CAGE CLAMP

connector from the termination

kit.
b: Strip 3/8” (9-10mm) from the

end of each ground wire (both

the provided pigtail and the

installed wire).
