Unison DRd enclosures are available in 6 or 12 module enclosures and are available for an
input voltage range of 85-300 V AC, 47-63 Hz. Enclosures are pre-wired and supplied with
three phase, 4 wire and ground, main lugs which are easily converted for split phase, 3 wire
and ground, operation without the need for additional materials.

Note:

DRd enclosures are available in 12, 24 and 48 circuit configurations.

In 48-circuit configurations, two DRd12-24 enclosures are cross-bussed to an
AX12X series main lug or main circuit breaker auxiliary enclosure. A single
Architectural Control Processor (Echo, Paradigm, or SmartLink ACP) provides
control for both enclosures.

DRd enclosures are supplied pre-wired for the specified voltage for your installation. All
enclosures operate at specified voltages within a frequency range of 47-63 Hz. Phases
within the enclosure may be bused together provided the maximum supplied current does
not exceed that of a three phase connection.

Chapter 1

Prepare for Installation

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 the ETC Systems Group the closest office of

purchase. See “Contacting ETC” on page 2.

Main Circuit Breaker Protection

Before you begin installing the DRd enclosure, make sure you have installed a main circuit
breaker cabinet or other readily accessible input power disconnect device. In certain
bussed and cross-bussed systems, this disconnect device may be the Unison AX series
auxiliary enclosure with a main circuit breaker.

WARNING:

DRd enclosures installed without an accessible power disconnect device
cannot be serviced or operated safely. Follow all local codes and
restrictions.

Before removing dimmer or control modules for service, de-energize main
feed to DRd and follow appropriate Lockout/Tagout procedures as
described in NFPA Standard 70E. It is important to note that electrical
equipment such as dimmer enclosures can present an arc flash safety
hazard if improperly serviced. This is due to available large short circuit
currents on the feeders of the equipment. Any work on energized equipment
must comply with OSHA Electrical Safe Working Practices.

Using 90° Copper Wire

To comply with UL requirements:

Use Copper Conductors Only, the torque rating for each Non-Class 2 field-wire
connector, and “Use 90°C conductors at the 75°C Ampacities”, where readily visible in
the field wiring compartment; Class 2 adjacent to each Class 2, field-wiring connector.

Use only 90°C-rated copper wiring installed in accordance with all applicable local electrical
codes.

CAUTION:

A two-wire circuit with separate hot and neutral conductors is required for every
branch circuit that will be connected to the DRd enclosure. Shared neutral (multi­wire) branch circuit arrangements are not recommended for phase control
dimming systems due to harmonics and potentially elevated neutral currents in a
shared neutral arrangement.

For retrofit installations where shared neutral circuits are already installed, or
enclosure lighting installations where the enclosure has a shared neutral, consult
ETC Technical Services for installation guidelines.

6 DRd Enclosure Installation Manual

Where to Install the Enclosure

Unison DRd enclosures are designed to be surface mounted on load bearing walls in an
electrical closet or a room with restricted public access. When required, an optional
semi-recessed installation kit is also available. It is recommended that you install the
enclosure at least 36” (915mm) above the finished floor to ensure clear view of the control
processor (E-ACP, S-ACP, or P-ACP) for programming and operation. Alternatively, DRd
enclosures may install to a floor standing pedestal (model DRd-Ped).

Clearance Requirements

DRd enclosures require 12” (305mm) top clearance for proper airflow through the cabinet.
For sufficient door clearance, install the enclosure with at least 17” (432mm) of front
clearance and a 6” (152mm) clearance to the left of the door hinge from walls or other
equipment.

• For your own safety, install a main circuit breaker cabinet or other readily accessible
power disconnect in the same area as the DRd enclosure. For cross-bussed
installations, this device may be the auxiliary enclosure. Main breakers not in the same
room must have a physical means to be locked off. ETC recommends adopting lockout
/ tagout procedures for your facility and following appropriate Lockout/Tagout
procedures as described in NFPA Standard 70E.

• A clean (not dusty) temperature-controlled environment with an ambient temperature
of 32-104°F / 0-40°C and ambient humidity of 10-90%, non-condensing.

CAUTION:

HVAC systems must at all times maintain the specified ambient temperature at the
enclosure. Dimming systems operating within 10°F (5°C) of the upper or lower
temperature limits must strictly follow installation and operation guidelines to
operate reliably.

• Restricted public access to prevent tampering.

• Soundproofing or performance area separation to muffle ventilation fan noise is
recommended.

• All CE equipment is tested to EMC category B environment.

Wire Routing and Specification

When planning wire entry into the enclosure, notice that conduit knockouts are provided
only on the sides of the unit. These knockouts are primarily used for bussing to an auxiliary
enclosure but may also be used for load or control wiring. Signal and power wiring must be
run in separate conduit per local code.

Due to the bend radii of certain size line feed wires and the location of terminations, special
attention is required for line feed wire entry. Reference the wiring guidelines below for
recommendations.

CAUTION:

Do not route line (input feed) wires through the back panel. Doing so requires bend
radii that violate NEC code, UL standards and because of undue stress at the wire
joint is likely to create a poor connection.

Line and load wire used with Unison DRd enclosures must be copper. Load wires
may either be stranded (preferred) or solid core. The use of aluminum wire is not
allowed in DRd enclosures.

Aluminum feed wires are supported only in the auxiliary (AX Series) enclosures.

Data Types and Topologies

LinkConnect and EchoConnect Control Wiring

Control stations communicate with the control processor using the LinkConnect or
EchoConnect station communication bus.

Termination is available for up to six home runs of LinkConnect / EchoConnect data runs
utilizing Belden 8471 cable (or approved equal) plus one 14 AWG (2.5mm2) ESD drain
wire. This wiring is topology-free and can be installed in any combination of bus, star, loop,
and home run. The total combined length of all wire runs cannot exceed 1,640 feet (500m).

CAUTION:

Note:

Auxiliary 24 vDC

Auxiliary power is required when you are installing certain Unison control stations. ETC
recommends using two 16 AWG stranded wires for 24 vDC auxiliary power to the control
station(s). Auxiliary power is topology-free.

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 +, data -) plus an ISO ground. ETC recommends the
use of Belden 9729 (or approved equal) wire with a single end of line termination (90­150). For best DMX performance, twist the wires together as close to the pluggable
connector as possible.

Note:

While the wiring terminations for LinkConnect, used in SmartLink and Paradigm
systems, and EchoConnect used in Echo systems, are similar, the communication
and control types are not interchangeable. Each product family requires a
dedicated station infrastructure that cannot be shared.

It is required that you terminate LinkConnect / EchoConnect station wiring and the
auxiliary power wiring in the same enclosure the station power module and
architectural control processor will be installed.

It is required that you terminate DMX control wiring in the same enclosure (rack 1)
where the architectural control processor will be installed.

Unison DRd enclosures are designed to be surface mounted on load bearing walls in an
electrical closet or a room with restricted public access. Alternatively the DRd enclosure
may be mounted on a pedestal (DRd-Ped). It is recommended that enclosures installed on
the pedestal floor stand also be secured to the wall for greater stability.

Mounting Individual Enclosures on a Wall

The wall must be strong enough to hold the enclosure fully populated with modules, conduit
and wire. See “Dimensions and Weights,” on page 7 and

“Modules Specification,” page 57.

Step 1: Determine where your enclosure will be installed using the weight and dimension

requirements detailed in “Where to Install the Enclosure,” page 7.

Step 2: Use the measured slot dimensions located in the graphic below to mark the hole

locations for the mounting hardware.

Step 3: Drill the holes and install the mounting hardware for each enclosure.

Step 4: Attach the enclosure to the wall.

Step 5: Check that the enclosure is level and plumb and tighten the mounting hardware.

• Four 3/8” (M8-M10) bolts or screws 2-4” (50-100mm) long, and suitable
wall plugs are suggested mounting hardware (lag bolts recommended).

• Both the surface and the mounting hardware must support the weight of
the enclosure unit fully populated with modules.

• Expose at least 1” (25mm) of threads for mounting the enclosure.

Mounting a DRd Enclosure on a Pedestal

The Unison DRd pedestal is designed with the same footprint as the DRd enclosure.
The acceptable conduit access in the bottom of the DRd overlaps the floor stand access
panel for contractor wiring and installation convenience. It is recommended to secure a
DRd enclosure installed on a pedestal to a wall for greater stability.

Unison DRd and AX auxiliary enclosures are designed to be surface mounted on load
bearing walls in an electrical closet or a room with restricted public access. One DRd
enclosure may be bussed to the AX series auxiliary enclosure, which may contain a main
circuit breaker or a main lug for power distribution to the adjacent DRd12 enclosure. Two
DRd12 enclosures may be cross-bussed to an AX12X auxiliary enclosure which is
designed to provide main lug or main breaker input feed termination to the adjacent DRd12
enclosures.

The wall must be strong enough to hold all enclosures fully populated with modules, conduit
and wire. Reference “Where to Install the Enclosure,” page 7 for weight, dimension and
clearance requirements.
