Main Circuit Breaker Protection
Before you begin installing the Unison® ERn enclosure, make sure you have installed a main circuit
breaker cabinet or other readily accessible input power disconnect device in the same room or in close
proximity of the installed ERn enclosure.
Lockout/Tagout
Equipment should be locked out while being repaired. Accidents which occur because machinery that
is being repaired and not locked out often result in serious injuries like amputations, fractures, and
even death. Locking out and tagging power at its source is important while repairing or adjusting
equipment because it ensures that power does not reach the equipment being serviced.
• To lockout means to place a lock on a device that prevents the release of energy. Locking out is
intended to prevent the unexpected startup or energizing of machinery and equipment during
service and maintenance operations.
• To tagout means to place a tag on a switch or other shut off device which warns others not to
start the piece of equipment. Tagout should only be used with lockout, unless locking out the
equipment is impossible.
General Lockout/Tagout Procedures:
• Notify all affected employees that a lockout/tagout procedure is ready to begin.
• Turn off the equipment at the control panel.
• Turn off or pull the main disconnect. Be sure all stored energy is released or restrained.
• Check all locks and tags for defects.
• Attach your safety lock or tag on the energy isolating device.
• Try to restart the equipment at the control panel to ensure that it is secured.
• Check the machine for possible residual pressures, particularly for hydraulic systems.
• Complete the repair or servicing work.
• Remove the safety lock and adapter.
• Let others know that the equipment is back in service.
WARNING: Enclosures installed without an accessible power disconnect device cannot be
serviced or operated safely. Follow all local codes and restrictions.
When the disconnect device is not located near the installed enclosure, the
disconnect must allow for proper lockout / tagout.

Data Types and Topologies
LinkConnect
LinkConnect is the station communication bus from the architectural control processor to the stations.
LinkConnect is based on Echelon® LonWorks™ with LinkPower bidirectional protocol, and uses one
pair of wires (data +, data - ). You should pull an additional 14 AWG (2.5mm2) wire for grounding
when not installed in grounded metal conduit.
Paradigm products are compatible only with the Paradigm ACP, Paradigm station power modules,
Paradigm architectural control stations, and Paradigm touchscreens.
LinkConnect is topology-free and polarity independent, you can install your LinkConnect data runs in
any desired combination of bus, loop, star, and home run. ETC recommends the use of Belden 8471
(or approved equal) wire. The total combined length of a LinkConnect wire run cannot exceed 1,640
feet (500m) with a maximum distance of 1,312 feet (400m) between any two devices.
DMX (Digital Multiplex)
DMX can address up to 512 channels of control. DMX is installed in a daisy chain topology and includes
one pair of wires (data+ and data-) plus an ISO ground. ETC recommends the use of Belden 9729 (or
approved equal) wire with a single end of line termination (90-150 For best DMX performance,
twist the wires together as close to the pluggable connector as possible.
Auxiliary 24 Vdc
Auxiliary power is required when you are installing powered Unison control stations. ETC recommends
using two 16 AWG (1.5mm2) stranded wires for 24 Vdc auxiliary power to the control station(s).
Auxiliary power is topology-free. Maximum auxiliary voltage runs are dependant by the wire gauge and
the distribution of auxiliary load determined by installation. The auxiliary supply is capable is of 36W
(1.5A at 24Vdc).
Note:
Repeater modules may be used to extend the Unison LinkPower station data bus an
additional 1,640 feet (500m) total wire, with a maximum distance of 1,313 feet
(400m) between the repeater and any station.
Note:
Terminate LinkConnect station wiring and the auxiliary power wiring to the rear
panel of the ERn that will host the Paradigm station power module (P-SPM).

DMX Input Termination: Screw Terminals Connector
DMX Input/Output Termination: Insulation Displacement Connectors
The graphic below illustrates DMX termination layout for an insulation displacement connector (IDC).
This connector type is intended for use with Belden 1583A (or approved equal, such as Category 5, 5E,
or 6) cable type.
The insulation displacement connector kit (IDC) may be requested from the factory but is not supplied
as standard. Request the IDC Pluggable Connector Termination kit, part number 4100A1013. Be
aware that cable other than Belden 1583A may have different color code for its wire pairs.
Terminate LinkConnect Control Wiring
Unison control stations communicate with the Paradigm architectural control processor using the
Echelon® LinkPower network. Termination is available for up to six home runs of LinkConnect data runs
utilizing Belden 8471 cable (or its equivalent) plus one 14 AWG (2.5mm2) ESD drain wire when the
data cable is not installed in grounded metal conduit.
LinkConnect wiring is topology-free and polarity independent utilizing a LonWorks network. Wiring
may be bus, star, loop, home run, or any combination of these. The total combined length of
LinkConnect data runs cannot exceed 1,640 feet (500m), with a maximum distance of 1,313 feet
(400m) between any two (un-repeated) communicating devices. Without a repeater, no device may be
more than 1,313 feet (400m) away from the Paradigm ACP.
Standard LON interoperability requires that there should be a maximum of only one repeater between
any two LON devices. This means that only one repeater module, whether a Paradigm repeater module
(P-REP) or a Paradigm dual repeater module (P-DREP), may be used per Paradigm ACP. Each individual
topology-free network can have no more than 62 stations with a repeater option and Paradigm ACP.
Note:
All low voltage control cables must run in separate conduit from power wires.

ERn Rack Mount Enclosure Installation Manual
1: Pull Belden 8471 (or approved equal type) control wiring to the rear panel of the ERn enclosure.
2: Strip 3/16” (5mm) of insulation from the ends of each wire pair.
3: Remove the LinkConnect connector (labeled LON).
• Notice the LinkConnect connector is labeled to indicate that
the connector is split between two segments, allowing three
station wire home runs per segment. This is effective only
when a Paradigm dual station repeater module (P-DREP) is
used. With the standard Paradigm station repeater module (P-
REP) you may connect up to six station home runs to the
connector for the single control segment.
4: Loosen the terminal screws for as many wire pairs you are
terminating. Keep in mind that the connector is split into two
segments. Be sure to terminate each wire pair to the correct
segment.
5: Insert each white (typical) wire from the pairs into an “A”
terminal on the connector and tighten the screw firmly to secure the wire into the connector.
6: Insert each black (typical) wire from the pairs into an “B” terminal on the connector and tighten
the screw firmly to secure the wire into the connector.
7: The 14 AWG (2.5mm2) ground wire can terminate to the ground bus located on the rear panel
of the ERn enclosure. Connect the other end of the ground wire to the green/yellow striped wire
connected at the architectural control station using a WAGO connector. Reference the related
station installation manual for further details.
8: Replace the connector to the rear panel I/O.
Note:
When utilizing a Paradigm station repeater module (P-REP) or Paradigm dual station
repeater module (P-DREP), terminate the repeated segment(s) and auxiliary power
wiring to the related rear panel I/O board.

Terminate Auxiliary Power
Auxiliary power is required when you are installing powered Unison control stations. ETC recommends
using two 16 AWG (1.5mm2) stranded wires for 24 Vdc auxiliary power to the control station(s).
Auxiliary power is topology-free. Maximum auxiliary voltage runs are dependant by the wire gauge and
the distribution of auxiliary load determined by each installation. the auxiliary supply is capable of 36W
(1.5A at 24 Vdc).
The auxiliary power connector (labeled Aux Power) provides termination
for up to 20 wires in the ten position pluggable connector. Each terminal
allows up to two 16 AWG (1.5mm2) wire and provides 24 Vdc power to
Unison control stations when used with the Paradigm ACP.
1: Pull auxiliary control power wiring (typically 16 AWG (1.5mm2) red /
black wire pair) to the ERn enclosure rear panel.
2: Strip 3/16” (5mm) of insulation from the ends of each wire pair.
3: Remove the auxiliary power connector from the I/O board.
4: Loosen the terminal screws for as many auxiliary wire pairs as you are
terminating.
5: Insert the black (typical) auxiliary power wire from the pair into a
“-” terminal on the connector and tighten the screw to secure the
wire into the connector.
6: Insert the red (typical) auxiliary power wire from the pair into a “+” terminal on the connectors
and tighten the screw to secure the wire into the connector.
7: Repeat steps 5 and 6 for all auxiliary power wires in the enclosure.
8: Replace the connector to the rear panel I/O.
Status Indicators
When power is applied to the ERn enclosure, the Paradigm repeater module LEDs located on the front
panel illuminate, indicating the status of the auxiliary power, LinkConnect control network, and
connected stations.
The Aux Power and LinkPower LEDs indicate in green when the Paradigm station power module is
connected properly and Aux and LinkPower are present. When there is an imbalance in LinkPower the
fault indicators illuminate. This condition typically means that the station wiring is at fault, however it
could mean a connected device is having an issue. A technician should inspect the system wire and
terminations first, then proceed to disconnecting devices to pinpoint the fault and correct it. The power
supply will update the fault indicators automatically when the fault condition is cleared.
• If the NET A line has a fault (is shorted or has leakage to ground), the Fault + LED lights.
• If the NET B line has a fault (is shorted or has leakage to ground), the Fault - LED lights.
• If neither fault LED is illuminated the data connections are properly installed and the stations are
receiving the data and power required for operation.
Note:
It is required that you terminate LinkConnect station wiring and the auxiliary power
wiring to the ERn enclosure rear panel I/O board that will host the Paradigm station
power module (P-SPM) or Paradigm station repeater module.
