Page 10: Where To Install The Enclosure
Where to Install the Enclosure Unison auxiliary 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 enclosure at least 914.4 mm (36 in) off the floor surface. Clearance Requirements Unison DRd enclosures require 305 mm (12 in) top clearance for proper airflow through the cabinet. -

• Soundproofing or performance area separation to muffle ventilation fan noise. Wire Routing and Specification Unison AX series enclosures have conduit knockouts on both sides of the cabinet for feed through to the adjacent DRd enclosure(s). The top and bottom are intentionally left blank to allow holes to be punched to match the incoming conduit. - Page 12 AX and AX12X Auxiliary Enclosure It is required that line feed enters from the top or bottom panels of the enclosure. The side knockouts are provided for cross-bussing and data interconnect feed through to the adjacent DRd dimming enclosure(s). The corresponding number of chase nipples with integral bushings are included. Wire Wire Access Interconnect wiring to...

Page 13: Install Enclosures
Chapter 2 Install Enclosures Mounting Auxiliary and DRd Enclosures Together One DRd may be bussed to the AX series auxiliary enclosure, which contains a main circuit breaker (MCB) for power distribution to the adjacent DRd enclosure. Two DRd12 enclosures may be cross-bussed to an AX12X which is designed to provide main lug or main breaker input feed termination to the adjacent DRd12 enclosures. - Page 14 Remove the knockouts from the side conduit plug on the DRd and auxiliary enclosure before installation. Only remove the knockouts that are adjacent to another enclosure. Install the DRd first, following the instructions as outlined in the DRd Enclosure Installation Manual.

Follow all local codes and restrictions. CAUTION: Load wires used with ETC dimming systems must be copper. Do not use wire containing aluminum. Line wires for the AX enclosures can be aluminum or copper. - Page 18 Main Lug Main Circuit Breaker Phase lugs Neutral lugs Neutral lugs Ground lugs Phase lugs Ground lugs Pull the line phase, neutral, and ground cables to the enclosure through the conduit openings previously prepared. Strip one inch of insulation from the end of each cable and terminate them to the lugs. Line connections are labeled L1, L2, L3 (for three-phase) and N.
