Control wires terminate to the right and left I/O boards in the
DRd rack enclosure.
Control wires can enter the dimmer rack from the top, bottom, or
either side, although ETC recommends that you pull control
wires into the rack from the bottom since all control terminations
are located near the bottom of the rack.

enclosures and includes terminations for:
•
24 Vdc Auxiliary Power input and output connector
•
LON Link Power connector

UL 924 emergency contact input for control bypass
•
Auxiliary rack (Dual Rack) cross-bussed interconnection
•
(2) DMX connections and a DMX pass-through connection
•

thru option (URTO) / Unison battery pack option (UBPO)
The left I/O board is required only when using
a Paradigm Architectural Control Processor
(P-ACP).
The left I/O includes terminations for:
•
Ethernet

The rack door has
been removed from
this graphic for clarity
of this procedure.
Load wires terminate to the load lugs on the
right side of the rack.
Load neutral and load ground wires terminate
on the neutral and ground bus bars located on
the back panel of the rack enclosure. An
exception to this is made for the DRd rack with
CE neutral disconnect. Neutrals are
terminated to the neutral disconnect on the left
side of the rack.
