15 Echo ACP Configuration Manuall
Install the Echo ACP
The Echo ACP is designed to slide in the bottom module slot of a Unison DRd enclosure.
All data terminations used with the Echo ACP are terminated to the left and right I/O boards
in the DRd enclosure.
Install the Echo ACP only after the DRd enclosure has been installed and all wires have
been terminated properly.
Step 1: Open the enclosure door.
Step 2: Rest the Echo ACP on the bottom lip of the enclosure, aligning both left and right
edges with the module slots.
W A R N I N G : Rack enclosures installed without an accessible power disconnect device
cannot be serviced or operated safely. Follow all local codes and
restrictions. Before installing or removing dimmer or control modules for
service, de-energize main feed to the rack and follow appropriate Lockout/
Tagout procedures as described in NFPA Standard 70E. It is important to
note that electrical equipment such as dimmer racks can present an arc
flash safety hazard if improperly serviced. This is due to available large
Short Circuit Currents on the feeders of the equipment. Any work on
energized equipment must comply with OSHA Electrical Safe Working
Practices.
N o t e : DRd enclosures are shipped standard with a module retention bar which secures
all dimmer and control modules into the enclosure, requiring a tool for module
removal.
Before installing the Echo ACP module or any other modules, be sure to release
the retention bar first, install the modules, then reengage and secure the retention
bar.
W A R N I N G : Never power up or operate the Unison DRd enclosure without all modules
installed. Failure to comply exposes you to dangerously high voltages that
may result in death by electrical shock.
Step 3: Slide the Echo ACP into the rack.
Step 4: Press gently on each corner of the
processor to ensure proper
connection with the card edge
connectors on the left and right I/O
boards.
Step 5: Install the remaining dimmer
modules into their corresponding
module slots.
Step 6: Slide the module retention bar to
the right and tighten the screws to
secure it in place.
Step 7: Close the DRd enclosure door and
follow the final installation and
power up procedures defined in the
DRd Enclosure Installation Manual.
When power is applied, the status
LEDs will illuminate and the ACP
will load the operating software.
