Prepare for Installation 7
Chapter 1
Prepare for Installation
Unpack and Inspect
Before you begin installation, check your shipment and confirm it arrived complete and undamaged.
Step 1: Check the shipping container for physical damage.
Step 2: If you find damage, document it to help with a claim against your shipper.
Step 3: Unpack your order and check the contents against the packing list to be sure your order
is complete.
Step 4: If you discover a problem, contact your dealer or nearest ETC office.
Main Circuit Breaker Protection
Before beginning installation of your Sensor3 dimmer rack(s), make sure you have installed a main
circuit breaker cabinet or other readily accessible input power disconnect device. See Appendix A:
Sensor3 CE Rack Specifications, page 36 for individual rack power requirements.
Energising the System
Sensor3 racks should only be energised by an authorised ETC representative. Wiring errors in
unauthorised installations may endanger personnel or cause system damage and failure.
Use 90°C Copper Wire
Use only 90°C-rated copper wiring installed in accordance with all applicable electrical codes.
.
WARNING: Dimmer racks installed without an accessible power disconnect
device cannot be serviced or operated safely.
WARNING: Do not attempt to energise the system without proper approval.
Energising the system without correct inspection may result in
serious injuries.
CAUTION:
Energising your system without proper inspection may result in equipment
damage that may not be covered under your warranty!
CAUTION:
A two-wire circuit with separate phase and neutral conductors is
required for every branch circuit that will be connected to the dimmer rack.
Shared neutral circuit arrangements are not recommended for phase-control
dimming systems due to harmonics and potentially elevated neutral currents
in a shared neutral arrangement.
For retrofit installations where shared neutral circuits are already installed, or
track lighting installations where the track has a shared neutral, consult ETC
Technical Services for rack installation guidelines.
The Neutral of the supply to the dimming system should have at least the
same cross-sectional area as the phase conductors

8Sensor3 CE Rack (ESR3) Installation Manual
Where to Mount the Rack
Sensor3 dimmer racks require 25 cm of top clearance for proper
airflow through the cabinet. To allow the door to open
sufficiently to install and remove modules, install the rack with
41 cm of front clearance and 15 cm clearance to the left of the
door hinge from walls or other equipment.
Dimmer Room Requirements
• A main circuit breaker cabinet or other readily accessible
input power disconnect device.
• A clean (not dusty) temperature-controlled environment
• Restricted public access to prevent tampering
• Soundproofing or performance area separation to muffle
ventilation fan noise
Please see Appendix A: Sensor3 CE Rack Specifications, page
36, for environmental details.
ESR3-12 racks are normally wall-mounted. ESR3-24 racks can be
wall or pedestal mounted. ESR3-36 and ESR3-48 racks are
designed to be free standing.
Install racks with the CEM3 about 100 cm from the floor. In
ESR3-12 and ESR3-24 racks, the CEM3 is in the bottom slot. In ESR3-36 and ESR3-48 racks, the CEM3
slot is in the middle.
Wire Routing
Sensor3 racks have access panels at the top and bottom, and conduit knockouts at the side. Line and
load wiring can enter from the top or bottom. Control cables can enter from the top, bottom or side.
Signal and power wiring must be run in separate conduits.
Note:
Additional Sensor3 racks of the same size are the
single exception to the 15 cm left clearance rule.
They can be installed side by side without
problems.

Installation of Racks
Mounting the Rack
• ESR3-12 racks are normally wall-mounted.
• ESR3-24 racks can be mounted to a wall or floor-mounted on an optional pedestal.
• ESR3-36 and ESR3-48 racks are floor standing.
Mounting Racks on a Wall (ESR3-12 and ESR3-24)
The wall must be strong enough to hold the racks. Please see Appendix A: Sensor3 CE Rack
Specifications, page 36 for rack and module weights.
Step 1: Determine where your rack will be installed using Figure 1: Sensor3 rack clearances on
page 8 and use the appropriate diagram from Figure 1 to mark your mounting holes.
Step 2: Use the mounting slot dimensions to mark the hole locations. You must supply your own
M10 mounting hardware.
Step 3: Drill the holes and install the hardware.
Step 4: Attach the rack to the wall.

Installing ESR3-36 and ESR3-48 Racks on the Floor
Step 1: Determine where your rack will be installed using Figure 1: Sensor3 rack clearances on
page 8 and use the appropriate diagram from Figure 2 to mark your mounting holes.
Step 2: Drill the holes and install your own M10 mounting hardware.
Step 3: Position the rack in the desired location.
Step 4: Adjust the leveling feet with an open ended 12 mm spanner until the rack is level and
vertical.
Step 5: Secure the rack to the floor using your mounting hardware.
Pedestal Mounting an ESR3-24 Rack
Step 1: Use Figure 2 to mark the location of the ESR3-24 mounting holes. The ESR3-24 pedestal
has the same floor mounting dimensions as the ESR3-24 rack.
.
Step 2: Drill holes or mount floor hardware and position the pedestal on them.
Step 3: Secure the pedestal base to the floor.
Step 4: Position the rack on the pedestal and align the mounting holes.
Step 5: Bolt the rack into place.
Note:
Sensor3 racks of the same size are the single exception to the 15 cm left clearance
requirement. They can be installed side by side without problems.
Note:
Sensor3 installation racks are tall, narrow, and heavy. Use caution to keep racks
stable until the rack is secured to the floor or wall.
Note:
You must supply M10 mounting hardware. The pedestal has four mounting holes
into the floor and four securing the rack.

Installation of Racks 11
Securing Sensor3 Racks to a Wall
Racks installed on the floor or a pedestal can also be secured to a wall for greater stability.
Step 1: Prepare the rack for floor or pedestal mounting (Installing ESR3-36 and ESR3-48 Racks
on the Floor on page 10 or Pedestal Mounting an ESR3-24 Rack on page 10).
Step 2: Mark the locations for your securing hardware on the wall.
• For ESR3-12 or ESR3-24 racks, use the diagram in Figure 1 to determine where you
need to install your hardware.
• For ESR3-36 and ESR3-48 racks, put the rack in position and mark the holes
directly.
Step 3: Drill holes or install mounting hardware in the marked locations.
Step 4: Finish mounting the rack to the floor or pedestal.
Step 5: Attach the rack to the wall with your securing hardware.
WARNING: Make sure the holes for the mounting hardware are located where
the hardware cannot come into contact with electrical wiring. Make
all modifications in accordance with your country’s electrical codes.

stability.
Step 2: Align the center of the fitting over the hole locations from the diagram. Mark the
position for two fitting bolts for each vibration pad (the middle holes are recommended).
Step 3: Drill the holes and secure the fittings to the wall. You must supply your own M10
mounting hardware.
Step 4: Remove the included bolt and washer from each vibration fitting.
Step 5: Position the rack on the wall so the centers of the vibration fittings align with the wall
mounting slots.
Step 6: Secure the rack to its vibration pad with the included bolts and washer.
Note:
Be sure this mounting method complies with
your countries building and electrical codes.
Note:
ETC’s wall mount vibration pads (ETC Part#
HW6111) attach to racks with the provided
bolts that are slightly larger than the top of
the keyhole slots. The bolt works fine
installed in the lower portion of the slot, but
the rack will mount slightly higher (approx.
10 mm) than the diagram indicates.
CAUTION:
Unless the all mounting and connections are done in a flexible manner, the
effectiveness of the vibration pads will be reduced or completely negated.
This includes the use of at least 30 cm of flexible conduit or flexible cable for
all of the electrical connections to the rack(s).

Installation of Racks 13
Floor Mounting Racks Using Vibration Pads
ESR3-36 and ESR3-48 racks can be floor mounted on optional
vibration damping fittings (ETC Part# HW6109).
Step 1: Determine where your rack will be installed using
Figure 1: Sensor3 rack clearances on page 8.
Step 2: Use the appropriate diagram from Figure 2: Hole
diagrams for mounting racks to the floor on
page 11 to mark your hole locations.
Step 3: Align the center of the vibration fitting over the
hole locations from the diagram. Mark the
positions for two bolts for each vibration pad.
Step 4: Drill the holes and secure the pads to the floor. You must supply your own M8 mounting
hardware.
Step 5: Remove the included bolt and washer from each vibration pad.
Step 6: Position the rack on the pads so the center holes of the pads align with the mounting
holes in the base of the rack.
Step 7: [Optional] If required, secure the rack to a wall using wall mount vibration pads (ETC
Part# HW6111). If the vibration pads have been requested for the installation, they are
included with the rack.
• Follow instructions from Securing Sensor3 Racks to a Wall on page 11 to drill holes
in the back of the rack for wall mounting.
• Mount the rack to the wall using the procedure from Wall Mounting Racks Using
Vibration Pads on page 12, above.
Step 8: Secure the rack to the pads with the included bolts.
Note:
Be sure this mounting method complies with
local building and electrical codes.
Level racks before marking the hole positions.
CAUTION:
Unless the all mounting and connections are done in a flexible manner, the
effectiveness of the vibration pads will be reduced or completely negated.
This includes the use of wall vibration pads when mounting to the floor and
at least 30 cm of flexible conduit or flexible cable for all of the electrical
connections to the rack(s).

Securing Multiple Racks (Optional)
Multiple racks can be connected to each other for greater stability.
Step 1: Use M8 spin lock bolts and lock nuts in the front and at the back to bolt the racks
together at the bottom.
Step 2: (ESR3-36 and ESR3-48 only) Remove six screws from the tops of adjacent racks, as
shown below.
Step 3: (ESR3-36 and ESR3-48 only) Place a rack splice plate over the empty screw holes and
replace the screws you removed in Step 2 as shown above.
Step 4: Repeat Steps 1, 2 and 3 until you have secured all the racks.
Note:
If you want to install the control cable through the side of the racks, you should
remove the side cable knockouts before connecting the rack.
Note:
The front bolt is difficult to reach – you may need a magnetic bolt-driver or socket
extension.

Installation of Racks 15
Rack Cabling Access
ESR3 racks have removable top and bottom access panels.
Conduit Connections
Step 1: Remove the desired access panel from the rack.
Step 2: Cut access holes in the top and bottom access panels.
Step 3: Install your cabling into the holes.
Step 4: Re-install the access panel so that there are minimal air gaps. See “Sealing Rack Air
Leaks” on page 30. for more information
.
Trunking or Wire Trough Connections
Step 1: Remove the desired access panels.
Step 2: Cut suitable openings to mate with the trunking or trough using a jigsaw or hacksaw.
Step 3: Reinstall panel on to rack
Step 4: Install a fiche paper lining or grommeting material in the access panel opening.
Step 5: Position the trunking or wire trough above the prepared opening.
WARNING: Cutting holes in the rack plates in situ may introduce metal debris
into the dimmer cabinet.
Note:
Wire openings must have fittings or linings to protect cable insulation from damage
by sharp metal edges.

Connect Line Power Wiring
ETC recommends routing line (feeder) cables first, load neutral
and load earth wires next, and load phase wires last.
Preparing Line Feed Cable
Line cable and power wire should enter the rack through the
designated top and bottom access points.
Line feed wires connect on the rack’s line phase, neutral and
earth bus bars. Each bus bar has one or two 12 mm studs to
secure a lug connection for the line feed wires. The installer
must provide the line feed connecting lugs.
Pull the line phase, neutral and earth cables to the rack
through the openings you prepared previously. See “Rack
Cabling Access” on page 15.
Step 1: Pull the line phase, Neutral and Earth cables to
the rack through the openings you prepared
previously.
Step 2: Cut the wires to length such that they reach the
correct stud
Step 3: Prepare the end of the wire and fit the desired
termination.
Step 4: Attach the lug to the correct phase, neutral or
earth stud as shown in Figure 8: Line and Load
Connections on page 16.
Step 5: Tighten the lugs to 59.5Nm.
CAUTION:
Line and load wires used with Sensor3
dimming systems must be copper. Do not
use wire containing aluminium or other
metals.
CAUTION:
Dress wires neatly and avoid leaving
extra wire inside the rack. Too much
clutter (especially along the right side of
the rack) can restrict air circulation and
reduce cooling efficiency. If cabling
interferes with airflow during operation,
the rack may shut down due to
overheating.
