their respective slots. The Architectural Control Processor installs into the

above the ACP.
N o t e :
All DRd enclosures are shipped with a dimmer module retention bar installed. The
dimmer module retention bar prohibits installed modules from being removed from
the enclosure without the use of a tool.
Before installing modules into the DRd, loosen the screws retaining this bar in
place, then slide the bar to the left side of the enclosure (door hinge side).
Complete the final installation procedure outlined below, then reengage the
module retention bar (see
). This bar is required to be installed in all
enclosures in order to maintain proper CE rating and NFPA70 compliance.
