DRd Rack Components

Unison DRd racks are available in 6 or 12 module enclosures and are available for an input voltage range of 85-300 VAC, 47-63 Hz. Racks 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.

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

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

• 100 / 200 VAC, 47-63 Hz, 1Ø

• 100 / 173 VAC, 47-63 Hz, 3Ø

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 Unison® rack 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 rack with a main circuit breaker.

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.

WARNING:

Rack 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 dimmer rack and follow appropriate Lockout/Tagout procedures as described in NFPA Standard 70E. It is important to note that electrical equipment such as dimmer racks 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.

CAUTION:

A two-wire circuit with separate hot and neutral conductors is required for every branch circuit that will be connected to the DRd rack enclosure. Shared neutral (multi-wire) 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 track lighting installations where the track has a shared neutral, consult ETC Technical Services for installation guidelines.

Where to Install the Rack Enclosure

Unison DRd rack enclosures are designed to be surface mounted on load bearing walls in an electrical closet or a room with restricted public access. It is recommended that you install the rack at least 36” (915mm) off the floor surface to ensure clear view of the Architectural Control Processor (S-ACP or P-ACP) for programming and operation. Alternatively, DRd racks may install to a floor standing pedestal (model DRd-Ped).

Clearance Requirements

Unison dimmer racks require 12” (305mm) top clearance for proper airflow through the cabinet. For sufficient door clearance, install the rack 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.

Rack Dimensions and Weights

Note:

Additional Unison® dimming and auxiliary racks of the same size are the exception to the 6” (152mm) hinge side clearance rule. Unison racks are designed for side by side use without issue.

Installation Environment Requirements

• For your own safety, install a main circuit breaker cabinet or other readily accessible input power disconnect device in the same area as the Unison DRd rack enclosure. For cross-bussed rack installations, this device may be the auxiliary rack. 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 follow 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.

• 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 rack, notice that conduit knockouts are provided only on the sides of the unit. These knockouts are primarily used for bussing to an auxiliary rack 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 rack wiring guidelines below for recommendations.

CAUTION:

HVAC systems must at all times maintain the specified ambient temperature at the rack. 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.

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 rack enclosures must be copper. Load wires may either be stranded (preferred) or solid core. The use of aluminum wire is not allowed in DRd rack enclosures.

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

Control Specifications

The riser below is typical of a small Unison system utilizing SmartLink Architectural Control Processors (S-ACP) for control and SmartLink architectural control stations for preset recall and sequence activation. A DMX input into the DRd racks provide an additional level of system control and integrates the architectural and theatrical lighting control systems.

Note:

Split phase applications require a simple field adjustment to the phase bussing.

10 Unison® DRd Rack Enclosure Installation Manual

The riser below is typical of a Unison system utilizing Paradigm Architectural Control Processors (P-ACP) for control and Unison architectural control stations for user controls. Paradigm systems provide a DMX input into the system for larger system integration and control. A Paradigm system also utilizes Net3 networking for an additional level of system wide control.

Control Wire Specification

The following table lists the recommended control wire types used in Unison DRd rack installations and the maximum length (aggregate) of wire runs allowed.

Data Types and Topologies

LinkConnect with LinkPower

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 (1.5mm

)wire for grounding 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 architectural control stations, and Paradigm touchscreens.

Throughout this manual LinkConnect is referred to by the protocol it uses, LinkPower.

Note:

DRd rack enclosures are shipped with the lugs installed in a top feed orientation by default. You may change the lug orientation to a bottom feed as needed.

1 Prepare for Installation 11

LinkPower 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.

Auxiliary 24 Vdc

Auxiliary power is required when you are installing powered 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:

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 1,312 feet (400m) between any two devices.

Note:

It is required that you terminate SmartLink / LinkPower station wiring and the auxiliary power wiring in the rack with the station power module installed.

Mounting Individual DRd Rack Enclosures

Unison DRd rack 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 rack may be mounted on a pedestal (DRd-Ped). It is recommended that rack enclosures installed on the pedestal floor stand also be secured to the wall for greater stability.

Mounting Individual Racks on a Wall

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

“Modules Specification,” on page 56.

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

requirements detailed in “Where to Install the Rack 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 rack.

• 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 rack unit fully populated with modules.

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

Step 4: Attach the rack enclosure to the wall.

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

Mounting Auxiliary and DRd Rack Enclosures Together

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

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

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

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

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

locations for the mounting hardware.

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

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

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

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

Step 4: Remove the conduit knockouts from the mating side conduit plugs on the DRd

and auxiliary rack enclosures before installation. Only remove the knockouts that are adjacent to another rack.

Step 5: Install the DRd rack first (follow instructions as outlined in “Mounting Individual

Racks on a Wall,” on page 13. Remember to install the DRd rack enclosure to

either side of the auxiliary rack in cross-bussed applications.

Step 6: Align the auxiliary rack against the DRd rack enclosure and mount it to the

previously installed hardware. Keyholes in the DRd and auxiliary rack enclosures are aligned with each other for mounting to Unistrut or Kindorf. With conduit holes mated, the bolt spacings are on 16” (406mm) centers (top left DRd and top left Ax rack) for installation convenience.

Rough-in Conduit to the DRd Rack

Line feed wires terminate on the main lugs provided.

The DRd12 rack is shipped from the factory with the main lugs in a top feed orientation. The lugs can be changed to a bottom feed orientation by removing the lug mounting bolt, rotating the lug 180°, and re-mounting the lug in the opposite lug mounting PEM. This is true for all DRd12 rack models.

The DRd6 rack phase lugs are both top and bottom feed by default and don’t require any change, but the neutral and ground lugs will require re-orientation for bottom feed.

When utilizing an auxiliary rack with the DRd rack, line feed wires from the auxiliary rack enter the DRd rack through the top side conduit knockout. For cross-bussed installations the line feed wires will be fed to the DRd rack through the conduit knockout on the adjoining side of the auxiliary rack.

Connect Line Power Wiring

Connect Line Feed in an Individual DRd Rack Installation

Line feed cables are terminated on the rack’s main phase lugs. It is best to route line (feeder) cables first, load neutral and ground/earth wires next, load phase and control wires last. In multiple rack installations, load neutral and ground/earth wires must terminate in the same rack as the matching load phase wires.

The bus bars are different for each rack type (DRd6 or DRd12) and each rack voltage (120, 230 or 240-277). Rack graphics are located on the next page for reference.

Step 1: Pull the line phase, neutral and ground cables to the rack through the openings

(conduit or other fittings) previously prepared.

Step 2: Strip the insulation from the end of each cable and terminate them to the lugs.

Reference the table below for wire stripping lengths.

• Line and neutral connections are labeled L1, L2, L3 and N. The equipment grounding/earthing lug is labeled with the universal grounding symbol for easy identification.

WARNING:

All rack terminations must be done with the power off. Dimmer racks installed without an accessible power disconnect device cannot be serviced or operated safely. In some instances, this device may be an auxiliary rack with a main circuit breaker. Follow all local codes and restrictions.

Before servicing, de-energize main feed to dimmer rack and follow appropriate Lockout/Tagout procedures as described in NFPA Standard 70E. It is important to note that electrical equipment such as dimmer racks 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.

CAUTION:

Line and load wires used with the Unison DRd racks must be copper. Do not use aluminum wire.

Note:

For DRd6 and DRd12 main lug, main breaker, and cross-bussed applications, reference the Unison Auxiliary Series Rack Installation Manual.

Connect Load Wires

Load wires are terminated to the load lugs on the right side of the rack. In 120 VAC and 240/277 VAC DRd racks, load neutral and load ground wires are terminated to the terminal strips on the back panel of the rack. In 230 VAC rack types, load neutrals are connected to the left side of the rack, stacked on top of the input feeds to maintain a true neutral disconnect.

Phase balancing of the loads is set from within the Architectural Control Processor (ACP) “Dimmer Setup” menu. Reference the related Architectural Control Processor configuration manual for details.

WARNING:

Use of emergency modules (ED15AFE or ER15AFE) in CE 230V DRd rack enclosures require the neutral (N) lug in place of the neutral jumper per module.

CAUTION:

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

Step 1: Route the load wires to the DRd rack(s) through the conduit previously installed.

Step 2: Prepare the load wires for termination:

a: Label each wire in the set with circuit designation.

b: Separate load circuit wires into ground, neutral and hot/live wire bundles.

Step 3: Strip 5/8” (16mm) of insulation from the end of each load wire.

Step 4: Route each load hot/live wire to its individual load output connection.

Step 5: Strip the neutral wire to the length indicated in the table above and terminate to

the neutral terminal assembly. Torque to the recommended value also indicated in the table above. For 230 VAC DRd racks, the neutral bus is located on the line input feed side of the rack.

Step 6: Strip the ground/earth wires to the length indicated in the table above and

terminate to the ground bus terminal. Torque to the recommended value also indicated in the table above.

Note:

Plan load wiring appropriately to avoid splicing wiring in the racks. Only one load wire per load terminal.

CAUTION:

Dress and terminate wires neatly and avoid leaving extra wire inside the rack. Too much clutter (especially along the right side of the rack) can restrict air circulation and reduce cooling efficiency. If cabling interferes with airflow during operation, the rack may be forced to shut down due to overheating.

Load wires should not cross between racks. Instead, they should enter the rack in which they will be terminated. Hot/Live and neutral load wiring must follow the same conduit/path for each circuit.

Step 7: Repeat steps 5 and 6 for each auxiliary power wire pair in the rack.

Step 8: Replace the connector on the right I/O board.

SmartLink™ / LinkPower (LON) Control Wiring

SmartLink and Unison control stations communicate with the Paradigm Architectural Control Processor using the LinkConnect 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-).

Throughout this document, LinkConnect is referred to by the protocol it uses, LinkPower.

Termination is available for up to six home runs of LinkPower (LON) data runs utilizing Belden 8471 cable (or approved equal) plus one 14 AWG (2.5mm

) ESD drain wire when the data cable is not installed in grounded metal conduit. LinkPower wiring is topology-free and polarity independent, you can install your LinkPower data runs in any desired combination of bus, star, loop, and home run (up to six home run termination points available), or any combination of these. The total combined length of LinkPower wire run 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 Architectural Control Processor.

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 station repeater module (P-REP) or a Paradigm dual station repeater module (P-DREP), may be used per Paradigm Architectural Control Processor (P-ACP). Each individual topology-free TP/FT-10 LonWorks network can have no more than 62 LON stations with a repeater option and Paradigm Architectural Control Processor (a maximum of 64 total devices).

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 architectural control stations, and Paradigm touchscreens.

Step 1: Pull Belden 8471 (or an equal type) control wiring and a 14AWG ground into the

DRd rack 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 LON connector from the right I/O board.

Step 4: Loosen the terminal screws for as many wire pairs you are terminating.

Step 5: Insert each white wire (typical) from the pairs into a “B” 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 an “A” terminal, next to the

previously installed “B” terminal on the connector and tighten the screws firmly to secure the wire into the connector.

Note:

It is required that you terminate LinkPower station wiring and the auxiliary power wiring in the rack the station power module will be installed.

Step 7: The 14 AWG (2.5mm2) ground wire can terminate in one of three ways:

• Connected between stations using Scotchlok™ connectors (3M® #314 insulation displacement connectors, ETC part number J4166).

• Grounded to metal conduit.

• If grounded metal conduit is not installed, connect the 14 AWG (green) ground wire to the DRd rack ground bus (the same as loads are grounded to) inside the DRd rack, and to the green/yellow striped wire connected to the control station using a Scotchlok connector. Reference the related station installation manual for details.

Step 8: Replace the connector to the right I/O board.

UL 924 Listed Panic Input

Termination is available for a UL 924 Listed dry contact input for control bypass. The two pin panic connector, labeled “PANIC”, accepts 16 AWG (1.5mm

) wire.

Step 1: Pull panic wiring into the DRd rack through the conduit

opening previously prepared.

Step 2: Strip 3/16” (5mm) of insulation from the ends of each

wire.

Step 3: Remove the 2 pin Panic connector from the right I/O board.

Step 4: Loosen the terminal screws.

Step 5: Insert each wire into the terminals on the connector and tighten the screws firmly

to secure the wires into the connector.

Replace the connector to the right I/O board.

Terminate DMX

DMX requires 120 termination at the last DMX device in the control run. Since a DRd rack with a Paradigm module installed can utilize up to two DMX inputs (2 DMX runs) the right I/O board provides convenient termination switches for use.

Notice the two termination switches labeled DMXA and DMXB. Each switch has three termination positions:

• Source - reserved for RDM termination (future

development).

• Off - no termination, DMX will pass through this device on to the next DMX device in

the data run.

• End - termination is on. Used for the last DMX device (DRd rack) that is physically

connected in the daisy-chained DMX In data run.

When a Paradigm processor is used in an Unison DRd rack enclosure, port B will be configured as an output and cannot be changed. port A is configured as either a DMX input or output. When used as an output the DMX termination should always be set to “Off”.

When a SmartLink processor is utilized in the Unison DRd rack enclosure, port A is automatically configured to be a DMX input and cannot be changed, port B is not used.

The Digital Addressable Lighting Interface option kit (DRd-DALI) controls 24 loops of 64 DALI compatible fluorescent ballasts in a broadcast mode. Each of the 24 DALI loops are linked one to one with a rack circuit for power control. For example, DALI loop 1 is controlled by DRd rack dimmer 1, DALI loop 2 is controlled by DRd rack dimmer 2, etc.

To control DALI fluorescent ballasts, the rack circuit must be populated with a dimmer module and assigned to DALI dimmer mode within the ACP software. Reference the related Architectural Control Processor programming guide for instruction to change dimmer mode.

Note:

A single DRd rack supports the use of either the DALI Option kit or the FLO Option kit, but not both in the same rack.

In addition, a single DRd rack supports the use of either the Unison Ride Thru Option (URTO) or the Unison Battery Pack Option (UBPO), but not both in the same rack.

Note:

The DALI ballast is powered by an external DALI loop power supply (supplied by others). This supply is connected externally of the DRd rack. Each DALI loop requires its own power supply and possibly more than one power supply depending on the load.

It is important to label the DALI fluorescent ballast load and control wiring sets with the circuit designation. Control wires terminate on the associated DALI board output loop terminal.

For example: If circuit 1 is configured as a D20 in DALI dimmer mode, DALI fluorescent ballast control wiring should terminate to the DALI board loop output terminals labeled “1”.

Step 1: Remove the DALI bus connector for loop outputs 1-6.

Step 2: Strip each wire in the pair back 1/4 inch (6mm).

Step 3: Using a small 3,35mm or 1/8” flat blade screwdriver, loosen the terminals and

insert each wire into the data “+” or data “-” terminals for the specific circuit loop. Data wires in the wire set are polarity independent.

Step 4: Tighten the terminal screw until the wire is held snugly.

Step 5: Repeat steps 1 through 4 for the remaining DALI loops through loop 6.

Step 6: Replace the DALI bus connector on the DALI board and repeat for the remaining

Checking the Rack Installation before Installing Modules

It’s a good idea to look over the entire installation before installing modules or applying power to the rack.

Step 1: Clean out dust, metal scraps or other debris from the rack interior.

• ETC recommends vacuuming the rack interior before installing modules.

Step 2: Check for loose connections, bare wires and damaged insulation.

Step 3: Manually spin the top cooling fan in both directions to be sure it is not obstructed.

Step 4: Correct air leaks caused by misaligned or removed conduit panel openings or

empty screw holes. For complete instructions for this procedure reference

Sealing Rack Air Leaks, page 52.

Step 5: Check resistance between phases, Neutral and Earth for short circuits. With the

power connector to the Power Supply/Dimming Engine still removed from the rack (this was accomplished prior to installing conduit and terminating any wires, see Remove the DRd Rack Power Supply/Dimming Engine Access Panel, page

18), and the all modules removed from the rack enclosure, including the Station

Power Module, check resistance between phases, neutral and ground busses with a digital voltmeter (DVM).

a: Phase to Phase; resistance should be 10M ohm or higher.

b: Phase to Earth (ground); resistance should be 10M ohm or higher.

c: Neutral to Earth (ground); resistance should be less than 1 ohm.

d: Phase to Neutral; resistance should be 10M ohm or higher.

Step 6: Check Load Wiring. Check resistance between the load terminals and the

Neutral buss.

a: Above 1M ohm is normal when no load is connected.

b: Between 6-300 ohm is a reasonable reading when loads are connected.

c: Below 1M ohm indicates a dead short in the load wiring and an infinite

reading indicates no load or an open circuit

WARNING:

Power must be turned OFF when you perform this procedure.

Before service, de-energize main feed to dimmer rack and follow appropriate Lockout/Tagout procedures as described in NFPA Standard 70E. It is important to note that electrical equipment such as dimmer racks 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.

CAUTION:

A dead short can cause module damage.

Page 56

52 Unison® DRd Rack Enclosure Installation Manual

Sealing Rack Air Leaks

After you have attached all the conduit to the rack and connected all wiring, you must seal any air leaks in the rack enclosure that was created during the installation process. ETC recommends use of urethane aerosol foam to fill air gaps in conduit fittings.

• Seal all conduit access holes.

• Completely cover all conduit openings with fiche paper and/or urethane aerosol foam or duct seal.

• Seal any air gaps caused by bent access panels.

• Fill in any gaps inside partially filled wiring conduit.

• Fill in other gaps or holes in the cabinet created during installation.

• Any rack enclosures that are installed side - by - side (bolted together) should only have minimal airflow between them.

CAUTION:

Air leaks can cause dimmer racks to overheat during operation and shut down. Air leaks can also cause a rack to shut down via an overtemp error, meaning that too little air is flowing through the front of the rack where it is needed to cool the dimmers.

Page 57

6 Final Installation and Power Up 53

Final Installation

Step 2: Reconnect the three cable assemblies to the unit.

a: For the cable bundle on the left side, insert the connector into receptacle until

you hear a click.

b: For the ribbon cable on the right rear side; insert the connector into the

receptacle. Press gently on both sides until it clips into place.

c: For the two-wire cable on the right side, gently press the connector straight

into the receptacle. This connection is also keyed and can only install one way.

Step 3: Rotate the access panel closed, then slide the panel up approximately one inch

to align the panel to the captured screws.

Step 4: Tighten the two captured screws, securing the access panel in place.

Step 5: Install modules into the rack.

a: Align each dimmer module with the correct module slot and firmly press into

place. The face of the dimmer module should be flush with the DRd rack enclosure.

b: Install the Station Power Module and Architectural Control Processor into

their respective slots. The Architectural Control Module (either SmartLink ACP or Paradigm ACP) installs into the lowest module slot. The Station Power Module installs into the slot directly above the ACP.

Note:

All 230 VAC DRd racks are shipped with a dimmer module retention bar installed. The dimmer module retention bar prohibits installed modules from being removed from the rack without the use of a tool.

Before installing modules into the rack, remove this dimmer module retention bar from the left side of the enclosure (door hinge side). Complete the final installation procedure outlined below, then Engage Module Retention Bar again. This bar is required to be installed in all 230 VAC DRd rack enclosures in order to maintain proper CE rating.

Step 6: Power up the rack. Before installing or removing dimmer or control modules for

service, de-energize main feed to dimmer rack and follow appropriate Lockout/ Tagout procedures as described in NFPA Standard 70E. It is important to note that electrical equipment such as dimmer racks 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.

Step 7: Switch all module circuit breakers to the “On” position.

Step 8: Reference the related Architectural Control Processor Programming Guide for

rack configuration setup and operation.

Control Bypass (Test Mode)

Test load circuits connected to the DRd rack enclosure by switching the “Control Bypass” switch to the “Test” position. The Control Bypass switch allows testing of lighting loads and provides temporary lighting before complete system commissioning. Return the switch to its “Normal” setting after the test is complete.

WARNING:

Never power up or operate the Unison DRd rack without all modules installed. Failure to comply exposes you to dangerously high voltages that may result in death by electrical shock.

Note:

CAUTION:

Turning the Control Bypass switch to the “Test” position with all module circuit breakers “On” will bring all lighting loads to full. To select only certain lighting loads for test, switch “Off” undesired module circuit breakers in the DRd rack enclosure.

CE 230V Emergency Modules

230V CE Emergency modules are non-standard for Unison DRd 230V Rack. On the occasion that your installation requires use of these modules, refer to the information outlined below for installation.

About Emergency Modules

The 230V CE Emergency modules provide two live outputs, one of which is dimmed or switched, and one of which is live whenever the breaker is turned “On”. This setup allows the modules to control battery-backed lighting, which requires both a constant and a switched or dimmed feed.

ETC offers two varieties of Emergency Modules - ED15AFE (15A Dimmer), and ER15AFE(15A Relay), painted red for easy identification.

Wire Termination

The constant output from the module is connected to the Neutral lugs at the left of the rack. Therefore, unlike Neutral Disconnect modules, Emergency modules provide a live output at these lugs, not a neutral connection.

Step 1: Locate the module slot in the rack where the Emergency module is to be fitted.

Step 2: Terminate the outgoing dimmed line to the terminals at the right hand side of the

rack.

Step 3: Terminate the outgoing (constant feed) line to the terminals at the left side of the

rack.

Step 4: Terminate the outgoing (Earth) line to the earth bar terminals.

Note:

When configuring the dimmer modules at the Architectural Control Processor (SmartLink ACP or Paradigm ACP), configure as either the ED15 or the ER15 module type.

Note:

ETC does not offer a Neutral Disconnect or RCD version of the emergency modules.

Step 5: Terminate the Neutral as described in the following section, dependant on your

rack type.

Non Neutral Disconnect Racks

For racks which have neutral jumpers fitted, the Neutral of the load, fed by the Emergency module, should be connected to the Neutral terminal of an adjacent module.

In racks without neutral jumpers (Neutral Disconnect racks), the Neutral of the load should not be connected to another load’s Neutral terminal. This can cause unwanted tripping of

RCD modules.

Instead, an auxiliary Neutral terminal must be fitted to the neutral plate and the loads should be connected to the terminal. If your rack was ordered with Emergency modules from the factory, the auxiliary neutral terminal will be factory fitted. If you require an auxiliary neutral terminal for field installation, please contact ETC as shown using the details in Contacting

ETC, page 2.
