Introduction
Welcome to the installation manual for the Unison
®
ERn Enclosure. This manual contains
the procedures for safe and efficient installation of wall-mount ERn series control
enclosures, including wire termination and option kit installation.
ERn series enclosures provide Unison architectural control to distributed Unison, Sensor+,
or other DMX512 systems. Used stand alone or in multi-processor network systems, the
Wall Mount ERn series offers elegant low-profile surface mounting, modular back-lit control
electronics, and the ultimate in architectural lighting control versatility.
The ERn enclosure is available in two sizes, ERn2 (single processor) and ERn4 (dual
processor), The ERn is available in three single phase voltage options, 100-120, 230 CE,
and 240 VAC to meet your installation requirements.
ERn External Processing Rack
The ERn2 enclosure supports a single Paradigm Architectural Control Processor (P-ACP)
and one Paradigm Station Power Module (P-SPM) or a blank module (ERn-BM). The
accessory tray in the bottom of the enclosure can be used for an additional accessory
option including a 5-port Ethernet Switch (ERn-NET) or a Redundant Rack Power Supply
(ERn-RPS).
The ERn4 enclosure supports up to two Paradigm Architectural Control Processors (P-
ACP) and two Paradigm Station Power Modules (P-SPM) or a Paradigm Repeater Module
(P-REP). Alternatively, the top two slots in the enclosure may be used for a Paradigm Dual
Repeater Module (P-DREP). The accessory tray in the bottom of the enclosure can be used
for an additional accessory option including a 5-port Ethernet Switch (ERn-NET) or a
Redundant Rack Power Supply (ERn-RPS).
