Introduction 1

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.

Warnings and Notice Conventions

These symbols are used in ETC documentation to alert you to danger or important
information:

P-DREP 7182A1004

Paradigm Dual
Station Repeater
Module

The Paradigm DREP module extends the system station bus
length 3,280 feet (1,000m) through two separate topology­free Echelon segments, each supporting 1,640 feet (500m).

• Tool-free installation into and ERn4 enclosure.

• The dual repeater module also adds support for up to 30
additional Unison architectural control stations.

• For use in an ERn4 enclosure only.

URTO 7180A1410

Unison Ride Thru
Option Kit

The URTO kit provides power for one Paradigm architectural
control processor in the host enclosure for a limited time
(minimum of 12 seconds) during brief power outages or drop
outs.

• If installed in an ERn4 enclosure, one URTO is required per
Paradigm ACP.

ERn-RPS 7180A1401

ERn Redundant
Power Supply

The ERn RPS provides an additional rack power supply that
powers the ERn enclosure if the primary rack power supply
fails.

Note:

The redundant power supply (ERn-RPS) is not supported in ERn4 enclosures at 230
VAC. Instead the ERn4 at 230 VAC is shipped from the factory with a rack power
supply installed in the top (normal) position and in the lower option module slot as
standard.

Note:

Notes are helpful hints and information that is supplemental to the main text.

CAUTION:

A Caution statement indicates situations where there may be undefined or
unwanted consequences of an action, potential for data loss or an equipment
problem.

WARNING:

A Warning statement indicates situations where damage may occur, people
may be harmed, or there are serious or dangerous consequences of an action.

Prepare for Installation

Preparations

Unpack and Inspect

Before you begin installation, check your shipment and confirm it arrived complete and undamaged.

Main Circuit Breaker Protection

Before you begin installing the Unison® ERn enclosure, make sure you have installed a main circuit
breaker cabinet or other readily accessible input power disconnect device in the same room or in close
proximity of the installed ERn enclosure.

Lockout/Tagout

Equipment should be locked out while being repaired. Accidents which occur because machinery that
is being repaired and not locked out often result in serious injuries like amputations, fractures, and
even death. Locking out and tagging power at its source is important while repairing or adjusting
equipment because it ensures that power does not reach the equipment being serviced.

• To lockout means to place a lock on a device that prevents the release of energy. Locking out is
intended to prevent the unexpected startup or energizing of machinery and equipment during
service and maintenance operations.

• To tagout means to place a tag on a switch or other shut off device which warns others not to
start the piece of equipment. Tagout should only be used with lockout, unless locking out the
equipment is impossible.

General Lockout/Tagout Procedures:

• Notify all affected employees that a lockout/tagout procedure is ready to begin.

• Turn off the equipment at the control panel.

• Turn off or pull the main disconnect. Be sure all stored energy is released or restrained.

• Check all locks and tags for defects.

• Attach your safety lock or tag on the energy isolating device.

• Try to restart the equipment at the control panel to ensure that it is secured.

• Check the machine for possible residual pressures, particularly for hydraulic systems.

• Complete the repair or servicing work.

• Remove the safety lock and adapter.

• Let others know that the equipment is back in service.

WARNING:

Enclosures installed without an accessible power disconnect device cannot be
serviced or operated safely. Follow all local codes and restrictions.

When the disconnect device is not located near the installed enclosure, the
disconnect must allow for proper lockout / tagout.

Maximum Current Input

The ERn enclosure draws a maximum current of 3 amps when fully populated.

Rack Mounting Specifications

An ERn configured for installation in a 19” equipment rack requires 5U of rack space for an ERn2 and
8U of rack space for an ERn4. ERn enclosures are provided with rack mounting brackets attached to
the ERn enclosure at shipment. The locking door attaches to the equipment rack for a secure
installation.

Dimensions and Weights

Installation Environment Requirements

• For your safety, you should install a circuit breaker cabinet or other readily accessible input power
disconnect device in the same area as the Unison ERn enclosure. Breakers not in the same room
must have a physical means to be locked off.

• A clean (not dusty), temperature controlled environment with the following conditions:

• ambient temperature of 32-104°F / 0-40°C

• ambient humidity of 10-90%, non-condensing

• Restricted public access to prevent tampering.

• All CE equipment is tested to EMC category B environment.
