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).
C l e a r a n c e R e q u i r e m e n t s
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.
