Introduction
Welcome to the installation manual for the Unison
®
ERn rack mount external processing
enclosure. This manual contains the procedures for safe and efficient installation of ERn
series processing racks, including wire termination and option kit installation.
The ERn enclosure is available in two sizes, ERn2 and ERn4, which can be supplied for
surface mounting on a wall (reference the Unison ERn Wall Mount Enclosure Installation
Manual) or with rack mounting brackets for installation in a standard 19” equipment rack.
The ERn is available in three voltage options, 120, 230, and 240 VAC to meet your
installation requirements.
The ERn provides Unison architectural control to distributed Unison, Sensor3, or other
DMX512 dimming systems. Used stand alone or in multi-processor network systems, the
ERn series enclosure offers elegant low-profile rack mounting, integrated back-lit control
electronics, and the ultimate in architectural lighting control versatility.
The ERn2 enclosure provides two module slots, one slot for the Paradigm architectural
control processor (P-ACP) and one for use of the Paradigm station power module (P-SPM)
or a blank (air flow) module (ERn-BM). The accessory tray in the bottom of the enclosure
can be used for either an optional redundant rack power supply (ERn-RPS) or blank option
module.
The ERn4 enclosure provides four module slots, two slots which can be used for Paradigm
architectural control processor’s (P-ACP) and an additional two slots for use of option
modules such as the Paradigm station power module (P-SPM) or a Paradigm repeater
module (P-REP). Alternatively, the top two slots in the enclosure may be used for a dual
paradigm repeater module (P-DREP).The accessory tray in the bottom of the enclosure
can be used for either an optional redundant rack power supply (ERn-RPS) or the blank
option module.
