sure your order is complete.
Main Circuit Breaker Protection
Before beginning installation of your Matrix Mk.II dimmer rack(s), make sure a main circui t break er
cabinet or other readily accessible input power disconnect device is installed. See Appendix B: Matrix
MkII Rack Specifications, for individual rack power requirements.
WARNING:
Dimmer racks installed without an accessible power disconnect
device cannot be serviced or operated safely.
Obtain ETC Approval to Energize the System
Following installation, ETC approval is required to apply power to the dimming system. Pre-approval
may be granted for some installations during the purchase process, or following a wiring inspection by
an authorised ETC representative after the system is installed. Wiring errors in unauthorised
installations may endanger operators or cause system damage and failure.
WARNING:
CAUTION:
Energizing the system without ETC approval may result in serious

Local Requirements
European Requirements
Matrix II has been designed to European standards for electrical switchgear
EN60439. It is CE marked. See Appendix C: Matrix II Declaration of Conformity.
Ensure that all European electrical health and safety, and working directives are
met when installing Matrix II.
Power Supply Requirements
Standard Matrix II racks are designed for operation with a single 3-phase star
380V – 415V RSTNE supply. Special order delta wired racks and multiple feed
racks are outside the scope of this manual. Contact your local ETC distributor for
more information. Please see Appendix B: Matrix Mk.II+ Rack Specifications, for
electrical specification detail s.
Supply Cable Requirements
Main power supply cables must be suitable for the type of dimming installation, the
anticipated load (with diversity factor) and to meet local regulations. Single
conductor or stranded conductors in either copper or aluminium may be used with
suitable terminations. Phase bars include 10mm (M10) bolts for termination of
mains power.
Load Cable Requirements
Cables connecting the dimmer outputs to load sockets must be suitable for the
type of dimming installation, for the anticipated maximum load and to meet local
regulations. Matrix II is designed for 3-wire per circuit load wiring (phase, neutral
and earth). Installati ons with s har ed neutr al conn ect ion s can not be used w ith
modules incorporating RCD protection.
Data Cable Requirements
Ethernet data cables should be at least CAT5 rated, and CAT6 is recommended
for dimming installations due to its increased bandwidth and future upgrade
potential.

Ventilation
o The dimmer room requires adequate ventilation to accommodate the heat
generated by the dimming system and to maintain a working temperature of less
than 35degC. For planning purposes allow for a thermal output of 3% of the
available power. Air conditioning is recommended. Ventilation input is through the
rear door grille and a grille at the bottom of the front of the rack. The hot air
exhaust is through the front of each module.

Accessibility
Allowing space around the rack (Rear access racks)
Allowing space around the rack (Swing frame racks)
o Rear access racks require adequate space in front to remove and replace
modules (minimum 80cm, 150cm recommended) and rear access to allow the
rear door for ventilation purposes and so that the door can be opened fully for
installation and maintenance access (minimum 100cm, 180cm recommended).
o Racks may be positioned with their side to a wall surface, and may be located
side to side as required.
o Where top access is planned for cables, ensure space above the rack is
adequate to allow for the bend radius of the supply cable, or access for main
power supply cable or bus bar trunking and load cable trunking. Allow adequate
space to allow for future cable checking and maintenance access to trunking lids.
o Swing frame racks require adequate space in front to remove and replace
modules and sufficient space for the door to be hinged fully open for access to
wiring terminations inside the rack. A distance of 1.8m is recommended between
the front of the rack and the wall.
o Racks may be positioned with their side and rear to a wall surface, and may be
located side to side as required.
o Where top access is planned for cables, ensure space above the rack is
adequate to allow for the bend radius of the supply cable, or access for main
power supply cable or bus bar trunking and load cable trunking. Allow adequate
space to allow for future cable checking and maintenance access to trunking lids.
Please see section 2 for mechanical dimensions.
Cable Routing
o Load cables and supply cables can be routed through the top or base of the
racks. Protect all edges to avoid cable insulation damage.

Positioning of Racks
Description (Rear Access racks)
Rear access racks are available in 160cm or 200cm
high versions and are available in 4 standard module
configurations for each version. Both height versions
are 60cm wide and 80cm deep. Each rack is supplied
with two side covers. The supplied intermediate side
panels may be discarded between racks.
Adequate space is required to the front for removing
and replacing modules and the processor, and space
at the rear should be available for fully opening the
rear door and allowing adequate access for wiring.
The rear door panel is also the main air intake for
ventilating the dimmers and must not be obscured.

Installation of Racks

Positioning Racks
It is important to ensure that the rack is located on a horizontal,
and closing correctly.
The racks are heavy, so it is advisable to prepare carefully before moving the racks into their final
position to avoid having to reposition racks if something is not ready, or the racks are not positioned in
the correct order. Check the delivery documents and installation drawings in advance to ensure that
the racks are positioned in the correct order because there are three versions of wiring and it is
difficult to differentiate between the versions visually without detailed internal inspection. Racks placed
in the wrong order can be inconvenient to change subsequently and if incorrectly placed will affect the
logical arrangement of module positions and channel numbering in the dimmer room.
Because the permitted module combination for similar size racks is not immediately obvious, it is
recommended that each rack version is initially identified by part number (see pages 1-3). If a mixture
of different modules is to be used, such as 4-c han nel and 6-channel modules or a combination of
3kW/16A and 5kW/32A modules or fluorescent or special modules, the different versions of racks will
have to be arranged to match the required module and channel numbering preferences.
Make sure the floor is clean, horizontal, flat and sound, and if several racks are to be located together,
mark out the floor in advance.
stable floor surface so that the rack is exactly vertical, as even a
minor amount of structural distortion in the framework can prevent
CAUTION:
Before attempting to move or position a rack, it is recommended that the side and top panels and rear
door are removed as this reduces the weight of the rack considerably (each rear access rack’s side
panel weighs approximately 35kg). Repla ce the panels as needed, after positioning.
For installations where bottom-access cable access is planned, prepare a suitable computer floor or
position optional rack plinths (100mm or 200mm high). If plinths are used, bolt these to the dimmer
room floor ensuring that they are in line and horizontal. Remove intermediate blanking plates to allow
for free cable access. Extreme care is required when lifting Matrix II racks into position. Bolt the racks
to their plinths when they are in place.
For top-access cable installations, and If racks are to be placed in a group side by side, there is no
requirement to bolt them together as the weight and cable infrastructure will ensure they won’t move.
If rigid fixing is preferred, the lifting eye bolts at the top of each rack can be used with custom-made
straps to lock adjacent racks together.
the modules from being inserted or removed easily. This is
particularly important in the case of swing frame racks, as any
distortion of the chassis frame will prevent the swing frame opening
Installing cable infr a s tructure
With the racks situated in the correct location, the next step is to position and fix the supply and load
access. The style and method of this depends local wiring regulations, licensing authority preferences
and electrical contracting techniques. The main supply to each rack may be a single tri-rated 400A 3phase armoured cable, 3-phase bus bar trunking with tap-off points for each rack, or individual
conductors in trunking or within the computer floor or optional rack plinths. Similarly, load cables may
be routed to each rack by individual cable ways, or trunking, or shared trunking with multiple tap-off
points. The installation of the external cable routing is not within the scope of this handbook.
Cable entry points are available through the top of the rack (the removable top panel may be cut as
required), or through the base of the rack where two panels are removable to provide access to space
beneath the rack. It is recommended that where possible the cable entry covers are removed from the
rack to reduce the risk of debris affecting the multi-pin connectors and terminations in the rack.
Protecting the racks during install at io n work
The dimmer modules and processor unit of a Matrix II rack should not be unpacked or installed until
all building preparation, rack installation and wiring work is complete. It is strongly recommended that
the internal sockets, terminals and associated PCBs are protected against damage from building
debris, dust ingress, metal shavings during the period until the dimmer room is finally cleaned and
tidy.

WARNING:
Matrix II racks may be ordered with a 400A internal bus bar/fuse assembly which is located on the
right side of the rear of the rack (rear access racks) or on the left side from the front (swing frame
racks). The bus bar may be used for either top or bottom cable access points and is factory fitted for
bottom cable access as shown here.

POSSIBLE TO ACCIDENTALLY APPLY POWER TO THE RACK
• Determine desired cable entry point (top or bottom).
• Remove the fuse cover panel (rear access rack) or the bus bar
termination cover (swing frame rack).
• Dress the feeder cables neatly into the rack and support them using
the perforated strap bars in the side of the rack to reduce
mechanical stress on the bus bar terminations.
• Once the cables are run to the desired termination point, strip the
cables and terminate the lugs to them, following the instructions
from the lug manufacturer.
• Secure the lug to the phase bar using the provided M10 bolt and
spring washer (see diagram).
• Tighten the bolt to 55 N-m (40 lb-f) using a torque wrench. (The
55Nm torque is the suggested tightness for standard engineering
steel bolts.)
• Repeat for all phase and neutral connections.

Terminals for the load wiring are located to the left of the rack at the rear and are accessible when the
rear door is opened. The terminals for 3kW circuits are arranged in groups of three (L, N, E)
corresponding to the number of channels in each row (3 modules) of the cabinet. Terminals for 5kW
and 12kW circuits are located in pairs with the earth terminals located separately but adjacent to the L
and N terminals. The load terminals are wired in groups for each row of modules. Load wires may be
stripped to bare ends or (better) stripped and fitted with crimp ferrules before insertion into the
terminal blocks.

Routing load cables
When drawing load cables into the
rack, ensure that no insulation is
damaged by edges of trunking or
access apertures. If the wiring has
been pre-designated and includes
temporary labelling to identify circ uit
numbers, be careful not to dislodge
labels during the wiring process.
Dress and terminate the wires neatly
and avoid leaving extra wire or
discarded sleeving in the rack. The
horizontal bars behind each tray are
perforated to accommodate cable ties
for this purpose. Load wiring should
not place any strain on the terminal.
In the diagram right, the load cables

when routing the load cables so they
do not obstruct the load terminal
screws. Data cables (d) are similarly
routed and clipped to the trays.
Load wiring should not cross between

are made at the rear of the processor module, on the data PCB that can be identified by the attached
ribbon cable. There is one data PCB per rack. Use provided lance and forms as a tie off for DMX and
Ethernet cables in the swing frame racks.
Data PCB at the rear of the Matrix II Processor tray.

b) DMX 2
c) Ethernet 1 RJ45
d) Ethernet 2 RJ45
Ethernet
Two standard RJ45 Ethernet sockets are provided on the data PCB, one for
the reporting connection (Dimstat) and one for the control data connection
(Merger). These sockets accept standard 10- or 100-base-T network
connections and receive dimmer intensity levels and transmit dimmer status
information using the DimSt at proto col.
Discrete DMX
Separate data terminals are included for DMX for those installations which are
not using an Ethernet data network. Two sets of terminals are included (see
diagram opposite). The terminals are PCB plug and socket type and may be
removed for wiring. DMX-1 includes the RS422 connections to DimSTAT and
DMX-2 is for DMX only.
DMX wiring should follow the standards and topology as defined by the USITT
standard. Wiring a Matrix II connector is as shown to the right. Unplug the
terminal section for wiring.

Finishing Installation
Visual inspection
After the supply, load and data terminations are completed, the rack should be checked as follows:
o Check all terminals and fuses have been tightened, especially the earth bonding
points
o Tidy all internal cables and add cable ties where needed
o Remove excess or unwanted wiring
o Fit the bus bar cover panel
o Secure all removable panels
o Remove all temporary protective covers
Cleaning
Before installing any electronic s modul es, en sure t hat the rack is free from dust, any building debris.
ETC recommends that the inside of the rack is vacuum cleaned to remove any debris from the wiring
installation process. Special attention should be paid to the multi-pin sockets used to connect to the
processor and modules.
When the rack is clean and ready for use, close and lock the rear door.

CAUTION:
Identify the modules used in the system and separate the processor from the Matrix II modules.

installation process. If different styles of module are planned for racks within the system, refer to the
installation documentation to identify which modules are to be used in each rack.

modules into the Matrix rack, ensure that all
terminals have been correctly tightened, the rack is
clean and any protective plastic has been removed.
Identifying modules
There is a wide range of modules available with the Matrix II system as listed in pages 2 and 3, and it
is important to fit them in the correct slot if a selection of modules has been specified with the system.
Each type of module sharing the same capacity and quantity of channels will fit the same appropriate
slot in the rack, but modules of different capacity and quantity of channels are prevented by keyways
in the multipin sockets.
In mixed installations where, for example, sinewave dimmers are specified for particular circuits and
SCR dimmers for others, it is important to ensure they are in the correct slot for operat iona l reaso ns.
Before starting to install the dimmer modules, check system schematics and design documentation for
a schedule of which module fits in each slot.

Section 9
Preventative Maintenance
ETC Matrix II dimming systems are designed for long and reliable service, but will benefit from annual
checks of parts of the system. This section outlines the sort of checks which should be part of any
regular maintenance regime.
Fuses
o With power switched off, remove each fuse and inspect for corrosion or any signs
of arcing
o Replace any fuse carriers which appear cracked or damaged in any way
o Replace the fuses and check they are tight in the fuse carriers and are not
inserted at an angle to the bus bars
o Replace all fuses every 5 years to prevent nuisance failure through aging
Terminations
o With the main supply isolated from the rack, check the bus bar fixings are tight.
o Check the tightness of all load terminations.
o Check all data cables and make sure they are correctly located in their sockets.
Ventilation
o On each module, depress the test button (on the front panel) for 5 seconds to test
the operation of the fan.
o Replace the fan if it does not run, or if it is noisy
General
o Clean all modules, fans and the rack.

Troubleshooting
Power loss
Total power failure
If all power to the rack fails (if it is not already obvious, the processor’s three phase
indicators will be off when there is a total power loss) initially check if the main
supply breaker has tripped. If not, check if there is any other equipment supplied
from the same source and whether or not that is working correctly. If other
equipment is working correctly, trace the supply route back to where the supply
splits to the rack and investigate the cause for the loss at that point.
Single or dual phase failure
Due to Matrix II’s distributed fusing design within the rack, a loss of one or two
phases could be caused by several different faults.
o If the processor indicates a phase has been lost, and yet all modules in the rack
are displaying power on, switch off all power to the rack and check the processor
supply fuses at the rear (top row of the fuse panel).
o If the processor indicates a phase has been lost, and the cor respo ndi ng colu mn
of modules appear to have switched off (indicator LEDs are off), check the mains
supply for a tripped phase breaker or fuse.
Single module power failure
If all power is lost to one module only, initially check the module supply fuse (63A)
on the Matrix fuse panel (only check with the main power off) and replace it if
necessary.
Single channel power failure
RCD tripping
RCD tripping on installation
RCD tripping after previously working correctly
If there is no output from one channel only (this will be reported by DimSTAT, on
the Processor and the module), it can indicate that the MCB or RCBO has tripped,
or there is an electronic failure within the module.
If an RCD trips during initial testing of the rack, it is almost certain there is a load
wiring problem. It is vital that both the live and neutral conductors of each channel
are routed together and connected to the corresponding phase and neutral outputs
from the same module. If the cause is not obvious, check first that there is no load
plugged into the circuit (the load may be at fault). With the load wiring isolated,
check there are no loose strands between terminals that could allow a leakage
current between the phase, neutral or earth connection.
Check that the load plugged into the circuit is not at fault by performing a PAT test
on the luminaire. If the load is not at fault, recheck the circuit to make sure there
isn’t another load connected in parallel which could be experiencing a leakage
current between L and E or N and E.

Fan not working
With Matrix II, the ventilation fans are located in each module. They are activated only when the
module reaches a pre-set internal temperature of 35degC, and they increase in speed in proportion to
the amount of heat present. To check the operation of the fan, depress the test button on the module
for about 5 seconds, after which time the fan will switch on. If it does not switch on, the fan may need
replacing.
Data loss
Data loss at the processor
No data present at the processor is displayed on the processor panel by an X
against the DMX legend. If this is the case, test the output from the control system
through any intermediary buffers, routers or switches.
If the data is correct, disconnect power from the rack and at the rear of the
processor swap the connections between inputs 1 and 2 (Ethernet 1 and 2 or DMX
1 and 2 depending on the data used) to see if the problem can be traced to the
different internal processing routes. If the data signal appears on the alternative
channel, the problem may be in the processor. If the second input does not
respond to the data signal, there is a problem with the data wiring to the rack.
Data loss at a single module
In the first instance, simply exchange the module with no data with an adjacent
module of the same type to check if the replacement responds to data. If it does,
the module is at fault. Check the module’s data cable (flat ribbon cable) to make
sure it is not damaged and is firmly located in its socket.
Data loss at a row or column of modules
If data is present at the processor but one row of modules has lost data, the
problem may be with the data connection PCB which is accessible from the rear of
the rack. Data is connected vertically through the rack via a ribbon cab le, so in the
first instance check that the cable connection is corr ect ly made and the ribbon
cable is locked in place.
