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.
Dimensions and Weights
N o t e : Additional Unison dimming and auxiliary enclosures of the same size are the
exception to the 6” (152mm) hinge side clearance rule. Unison enclosures are
designed for side by side installation.
