Procedure

WARNING:

Power must be turned OFF when you perform this procedure. Before service,
de-energize main feed to dimmer enclosure and follow appropriate Lockout/
Tagout procedures as described in NFPA Standard 70E.

It is important to note that electrical equipment such as dimmer enclosures 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.

Step 1: Turn off power to the DRd enclosure.

WARNING:

Failure to disconnect all power to the DRd before working in the enclosure
could result in serious injury or death.

Step 2: Loosen screws on the module retention rail on the left side of the DRd enclosure and slide

the rail to the left.

Step 3: If installed, remove the Architectural Control Processor, Station Power Module, and at

least three dimmer modules from the lower portion of the enclosure to provide work space
inside the enclosure.

Step 4: Use a digital voltmeter and verify that power is off by checking voltages for all

combinations between the phase bars, neutral, and ground (earth).

Echo Network Termination Kit

Step 5: If the Category 5 cable running to the enclosure does not have a female RJ45 connector,

reference the included Ethernet Cat5 Termination Kit Setup Guide to terminate
Category 5 wiring to the provided Cat5 mounting box and connector.

• When installing, attach the Cat5 mounting box at the back of the enclosure, left of
the neutral lug and at least one inch from any exposed copper.

WARNING:

Failure to properly space the mounting box from the exposed power lugs could
result in damage to the DRd and its components and poses a serious safety
risk.

Install the I/O card

Step 1: Align the network termination card to the mounting studs at the lower left of the enclosure.

Step 2: Use four of the included screws to secure the card to the enclosure.

Step 3: Connect the included Ethernet patch cable from the previously installed Cat5 termination

box to the receptacle on the network termination card.

Step 4: Tie back and secure the Ethernet patch cable neatly inside the enclosure to ensure it does

not interfere with module installation and DRd operation.

Step 5: Replace the dimmer modules, Station Power Module and Architectural Control Processor

into the slots they were previously removed.

Step 6: Slide the module retention bar to the right and tighten the screws to secure it in place.

WARNING:

Step 7: Supply power to the DRd enclosure.

Step 8: Unless structural changes are being made to the existing system, no dimming or

result in death by electrical shock.

architectural re-configuration should be necessary. If the system is being modified,
