Page 7: Drd Rack Components
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. - Page 8 • The use of a station power module provides power nd control for architectural control stations. • Use a SmartLink station power module (S-SPM) in a DRd rack enclosure to provide power for up to 16 SmartLink architectural control stations when used with the SmartLink ACP.

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. -
Page 10: Maximum Current Draw Of Racks
Wire bending space limits the feed to the AX12X-MCB rack to 400A maximum. ETC installs a 100% rated two pole breaker (or two poles from a three pole breaker) in the AX12X-MCB, for a total deliverable current of 400A in a single phase (split phase) configuration. -
Page 11: Where To Install The Rack Enclosure
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. -
Page 12: Installation Environment Requirements
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. -

(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. - Page 15 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 (90- 150).

Page 17: Mounting Individual Drd Rack Enclosures
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. -
Page 18: Mounting A Drd Rack Enclosure On A Pedestal
Mounting a DRd Rack Enclosure on a Pedestal The Unison DRd rack pedestal is designed with the same footprint as the Unison dimmer rack. The acceptable conduit access in the bottom of the DRd rack overlaps the floor stand access panel for contractor wiring and installation convenience. It is recommended to secure a DRd rack installed on a pedestal to a wall for greater stability. -
Page 19: Mounting Auxiliary And Drd Rack Enclosures Together
Mounting Auxiliary and DRd Rack Encl osures 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. - Page 20 Step 7: Install the ETC supplied 2 1/2” (64mm) nylon insulated chase nipple and 2 1/2” (64mm) locknut between the auxiliary and DRd rack enclosures. Step 8: For cross-bussed DRd12-24 rack installations, install the second DRd12-24 by following steps 4 through 7 above.
