Preparations
Unpack and Inspect
Before you begin installation, check your shipment and confirm it arrived complete and
undamaged.
Step 1: Check the shipping container for physical damage.
Step 2: If you find damage, document it to help with a claim against your shipper.
Step 3: Unpack your order and check the contents against the packing list to be sure
your order is complete.
Step 4: If you discover a problem, call ETC Systems Group at (608) 831-4116.
Main Circuit Breaker Protection
Before you begin installing the Unison® external processing rack 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 to the installed ERn enclosure.
WARNING:
Lockout / Tagout
Note:
Equipment should have power disconnected and be locked out while being repaired.
Accidents which occur because equipment that is being repaired and not locked out can
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.
Rack 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 rack enclosure,
the disconnect must allow for proper lockout and tagout.
While ETC does not intend to qualify your facility Lockout/Tagout procedures, we
have provided a generic guide below for your reference as needed.
6 Unison® ERn Wall Mount Enclosure Installation Manual
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.

Data Types and Topologies
LinkConnect
LinkConnect is the station communication bus from the Architectural Control Processor to
the stations. LinkConnect is based on Echelon
protocol, and uses one pair of wires (data +, data -). An additional 14 AWG (2.5mm
for grounding is required when not installed in grounded metal conduit.
ETC uses two types of LinkConnect networks, for SmartLink and Paradigm systems. While
the wiring for LinkConnect in SmartLink and Paradigm systems are the same, the two
communication and control types are not interchangeable. SmartLink products are
compatible only with the SmartLink ACP, SmartLink Station Power Module, and SmartLink
Architectural Control Stations. Paradigm products are compatible only with the Paradigm
ACP, Paradigm Station Power Modules, Unison Heritage Control Stations, and Paradigm
Touchscreens.
LinkConnect is topology-free and polarity independent, you can install your LinkPower 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 LinkPower
wire run cannot exceed 1,640 feet (500m) with a maximum distance of 1,312 feet (400m)
between any two devices.

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 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. DMX devices manufactured by ETC are compliant with the USITT DMX512A
standard.
Auxiliary 24 Vdc
Auxiliary power is required when you are installing powered Unison control stations. ETC
recommends using two 16 AWG (1.5mm
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).

When utilizing a Paradigm Station Repeater module (P-REP) or Paradigm dual
station repeater module (P-DREP), terminate the affected LON segment(s) and
associated auxiliary power wiring to the top right I/O board in the ERn4 enclosure.
Step 1: Pull Belden 8471 (or approved equal) control wiring into the ERn4 enclosure
through the conduit opening previously prepared.
Step 2: Strip 3/16” (5mm) of insulation from the ends of each wire pair.
Step 3: Remove the LinkPower connector
(labeled LON) from the top right I/O
board.
• Notice the LinkPower connector
is labeled to indicate that the
connector is split between two
segments, allowing six 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 twelve station home runs connect to
the single control segment.

Step 4: Loosen the terminal screws for as many wire pairs you are terminating. Keep in
mind that the connector is split into two segments when used with a Dual
Repeater Module. Be sure to terminate each wire pair to the correct segment.
Step 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.
Step 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.
Step 7: The 14 AWG ground wire can terminate to the ground bus located inside the ERn
enclosure.
• If grounded metal conduit is installed a ground wire may not be required for
termination. Reference the related station installation manual for details.
Step 8: Replace the connector on the top right I/O board.
Terminate Auxiliary Power
Note:
Auxiliary power is required when you are installing powered Unison control stations. ETC
recommends using two 16 AWG (1.5mm
2
) 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 powering up to four Paradigm Touchscreen
Stations and 28 interface stations.
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(1.5mm
2
wire and provides 24 Vdc power to Unison control stations when used with the Paradigm
ACP.
When utilizing a Paradigm Station Repeater Module (P-REP) or Paradigm Dual
Station Repeater Module (P-DREP) in an ERn4 rack, terminate the repeated LON
segment(s) and auxiliary power wiring to the top right I/O board.
Step 1: Pull auxiliary control power wiring (typically 16 AWG (1.5mm
2
) red / black wire
pair) into the ERn enclosure through the conduit opening previously prepared.
Step 2: Strip 3/16” (5mm) of insulation from the ends of each wire pair.
Step 3: Remove the auxiliary power
connector from the right I/O board.
Step 4: Loosen the terminal screws for as
many auxiliary wire pairs as you are
terminating.
Step 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.
Step 6: Insert the red (typical) auxiliary power wire from the pair into a “+” terminal on the
connector and tighten the screw to secure the wire into the connector.
Step 7: Repeat steps 5 and 6 for each auxiliary power wire in the enclosure.
Step 8: Replace the connector on the right I/O board.

Status Indicators
When power is applied to the ERn enclosure, the Paradigm Station Repeater Module LEDs
located on the front panel illuminate, indicating the status of the auxiliary power, LinkPower
control network, and connected stations.
The Aux Power and LinkPower LEDs indicate in green when the Paradigm Station Power
Module is connected properly and auxiliary power and LinkPower are present. When there
is an unbalance in LinkPower the fault indicators illuminate. This condition typically means
that the station wiring has a fault, however it could mean a connected device is having an
issue. A qualified 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.

Install Redundant Power Supply
Install the Redundant Rack Power Supply in the bottom
option slot of the ERn enclosure and secure it in place
with the two captured screws.
The ERn Redundant Power Supply (ERn-RPS) is an additional rack power supply that
powers the ERn enclosure if the primary rack power supply is removed or fails.
Note:
The Redundant Power Supply (ERn-RPS) is not supported in an ERn4 rack
enclosure at 230 VAC. Instead, the ERn4 rack at 230 VAC requires two rack
power supplies installed in the top (normal) position and in the lower rack option
module slot as standard.
Status Indicator
When the Redundant Power Supply is installed properly, and power is applied to the ERn
enclosure, the LED will indicate in green if the supply is powered. If the LED is off but the
primary rack supply status indicator is on, the Redundant Power Supply requires servicing.
Alternatively, if the primary rack supply status LED is off, but the Redundant Power Supply
is on, the primary rack supply requires service. Contact ETC Technical Services for
assistance. See “Contacting ETC” on page 4.
