3. INSTALLATION
3.1 Dimmer room
3.1.1 Preparation
Determine the dimensions of the dimmer room so as to place all EURODIM Twin Tech cabinets easily. Provide for an open space of approximately 90 cm in front of the cabinets to facilitate maintenance. Before attempting to move the rack(s) into the final position, check access routes to the dimmer room for space to manoeuvre through doorways and around corridor corners. The cabinets can be placed against a wall, side by side or back to back.
The supply cables and the load cables can enter the wiring compartment either from the top or bottom of the cabinet. See drawing for size and location of cable entries.
Dimmer Room Requirements
A clean (not dusty) temperature-controlled environment.
Restricted public access to prevent any unauthorised tampering with the dimmer settings.
Soundproofing or performance area separation to muffle ventilation fan noise.
Acoustic measurements are available from ADB Lighting Technologies.
Provide for a free space, minimum 30 cm above the EURODIM Twin Tech so as to facilitate the exhaust airflow. If an optional “Silencer” is used, then more space may be necessary. The dimensions and weight of the cabinets are included in the Chapter “Characteristics”. Plan for fire extinguishers in compliance with local regulations. The lighting of the area should be sufficient for maintenance and inspection. A level of 300 lux is considered satisfactory.
Plan for mains outlets in the room, independent of the supply of the dimmers.
Plan for an Ethernet network to the control room an d a cable for remote “CPU1 - CPU2” selection (if applicable).
EURODIM Twin Tech cabinets are professional equipment and relevant safety rules are applicable. EURODIM Twin Tech cabinets should be placed in areas that are accessible only to persons responsible for maintenance, surveillance or repair of the equipment.
Please refer to local regulations and requirements.
Such an area should be located as close as possible to the stage or studio, in order to reduce the length of the electrical cables, and therefore, the cost of installation. At the time of installation of the cabinets in the area, it should be completely unobstructed; that is, that all engineering work, wall or floor covering work, painting, electric lighting work, drilling, welding, etc., must be completed.
Do not install the plug-in modules until all wiring installation is completed.
EURODIM Twin Tech has been designed to European standards for electrical switchgear
EN60439. It is CE marked. See chapter 11.10 CE Declaration Document for EURODIM Twin
Tech. www.adblighting.com

EURODIM TWIN TECH
3.2 Ventilation of the dimmer room
The dimmer room should be dry at all times, free from dust and ventilated in such a manner as to comply with the following:
- Relative humidity: 5% to 90% without condensation.
- Temperature between + 5 °C and + 35 °C (ideal: + 20 °C).
In order to size the air-conditioning equipment required for the dimmer room, refer to the following dissipations:
- Cabinet electronics including
- Thyristor modules: o 4 x 3 kW modules : o 3 x 5 kW modules : o 1 x 10 kW modules :
150 W global value for CPU(s), PSU and fans
37 W per dimmer (worst case)
69 W per dimmer (worst case)
170 W per dimmer (worst case)
- Sinewave modules: o 4 x 2.5 kW modules : 60 W per dimmer (worst case)
- No-load losses of sine wave dimmers: o Sine wave dimmers have a no-load loss of approximately 4 W per dimmer.
In practice, you may consider a utility factor of 0.6: that is, on the average, 60% of the dimmers are at full load, while 40% are off.
3.2.1 Example No. 1
A dimmer room with a EURODIM Twin Tech cabinet equipped with 128 thyristor dimmers of
3 kW and a second cabinet with 96 thyristor dimmers of 5 kW. The cabinets are fitted with a back-up power supply for the processor unit. Utility factor = 0.6
1) Cabinet N°1
Electronics: 1 x 150 W
Dimmers 128 x 37 W x 0.6 = 2841 W
2) Cabinet N°2
Electronics: 1 x 150 W
Dimmers 96 x 69 W x 0.6 = 3974 W
ROOM TOTAL: 7115 W (1 W = 0.86 kcal/hour) or 6119 kcal/hour.
In this example, it will be necessary to evacuate approximately 7115 W of losses. www.adblighting.com

The weight and dimensions of the cabinets are included in Chapter “Characteristics”. Prior to positioning each cabinet, ensure that the floor is flat and horizontal to ensure a good weight distribution.
It is the responsibility of the system integrator or installer to check if the cabinet weight load can be supported by the building structure!
After you have positioned the cabinets:
- Do not remove the plastic, so as to keep a protection during the cabling works.
- Cut the plastic to have an access to the cabling areas.
- Remove the doors of the contractor's areas by simply opening the door hinges.
CAUTION! The doors are grounded / earthed.
Gently remove this grounding connection WHICH MUST BE
RESTORED when the door is eventually put back in place.
During the cabling works, leave the doors in a clean area and covered with a protection. www.adblighting.com

4.1 Controller Electronics - CPU/ PSU crate
The CPU/ PSU crate is already mounted in our factory. If a removal is required, loosen the 4 screws and remove the complete crate gently. Replace the connected flat cables with caution.
4.2 Supply voltage
The high voltage/low voltage power transformer MUST ABSOLUTELY provide a three phase star system with available neutral (3NPE-400), and rated line voltage 380 V to 415 V between phases and 220 V to 240 V rated voltage between each phase and neutral. See
“Protections” for more details.
The supply cable must have the four current-carrying power conductors (not necessarily the
PE conductor) twisted under the same sleeve, in order to reduce the electrical noise induced by large dimmed currents.
The neutral conductor must be of equal or larger size than the phase conductors.
See the Appendix to this manual for more details about power supply systems for dimmer systems. www.adblighting.com
Installation manual - Page 11
Version 1.2
4.3 Supply busbar
EURODIM TWIN TECH
The three phase connection points are labelled L1 (phase No. 1, phase R), L2 (phase No. 2, phase S) and L3 (phase No. 3, phase T).
The Neutral is labelled N and the colour code for the Neutral is blue, as per IEC
Recommendation 446.
The Phase and Neutral connection bars have 2 holes of Ø 13 mm, with 22 mm distance between centres. Connections are suitable for size M 12 bolts and nuts, for connection of up to four supply conductors. The conductors must be fitted with cable lugs. www.adblighting.com
Installation manual - Page 12
Version 1.2
EURODIM TWIN TECH
4.3.1 Protected Earth (PE)
4.4 Connecting power supply cables.
The Protective Earth (PE) on the busbar connection is a bolt and nut, size M10. Colour code: green/yellow. The equipotential connection, connecting the metal frame, is provided at the top of the supply cabling compartment. This connection is already wired to the busbar PE. An additional PE connection is provided on the cabinet’s bottom of the supply compartment. All necessary nuts and washers are included.
Supply cables can be wired in parallel, whilst each of these cables must contain the three phases and the Neutral under the same sleeve. This cable must be protected in the switchboard. The total size of the conductors must be chosen depending on the total power of the dimmers, the utility factor, the general protection on the supply side, the voltage drop in the line and local regulations. We suggest the use of several cables placed in parallel, to facilitate the work of the contractor: the cables usually have a bending radius of min. 15 times their external diameter. Respect an angle of 30 degree to connect the supply cable in order to achieve necessary distance between the cables and busbar. Use the wholes on bottom and top to connect the cable wraps for stress relief. www.adblighting.com

5. SEQUENTIAL DIAGNOSTICS (Optional)
In case the client has ordered the option:
One Sequential Diagnostics kit must be installed for each dimmer cabinet in the installation.
The sequential diagnostics function is similar in function to the diagnostics already used in the EURODIM 3. The dimmer channels are examined one after the other (sequential) and the value is reported either to the local Human Interface or a remote program running the
TTD Management Software.
The communication to a single remote reporting pc is done via the proprietary ADB ADN protocol based on an Ethernet Network to a Personal Computer with the Windows Operating
System running the TTD Management Software. The Ethernet information is generated by each EURODIM Twin Tech controller and physically available for each individual controller on dedicated RJ45 connectors (Two possible per cabinet if double controller options are used).
The TTD Management Software and the necessary hardware are available as option for the
EURODIM Twin Tech cabinet, which shall be ordered separately installation.
Standard functions include
Presence of Mains and DMX signal
Processor (active) check
Over Temperature
Fan Failure (Information per FAN!)
DMX Control Levels
Local test of a dimmer (steady, flash or chaser)
Automatic self-test of control electronics.
Error messages and all events/parameters are available for display locally on the EURODIM
Twin Tech Human Interface Controller and/or remotely on the TT Dimmer Manager PC connected via an Ethernet Network. (use of ADN protocol)
Scan Load and the related functions are pre-show

NEUTRAL (blue) cable from the cabinet power supply must pass through.
Overview of EDTT cabinet - Supply Compartment
All the hardware installations are to be performed in the left hand contractor department. This is where the EURODIM Twin Tech cabinet receives the power supply. It is advisable to mount the hardware before you introduce the power supply cables, because there is more space for the installation left.
The only cable which shall pass through the TI (power coil) is the neutral cable (blue) - the other supply lines pass on the outside of the TI. The TI coil has a latching mechanics allowing to open the coil and to pass the (large) neutral cable through it. There is a cable
(approx. 150 cm) with grey and blue wire. This cable is to be brought to the upper right hand side of the cabinet, where the PCB 3015 is to be mounted. www.adblighting.com

The black lines are ETHERNET connections between the EURODIM Twin Tech, Switch and
PC running the TTD Management Software. This software must only be installed one time.
At the same time a lighting control desk (which must support ArtNET communications protocol) may be connected to the ETHERNET Switch. To simplify the image the control desk has not been included in the drawing. Both the PC running TTD Management Software and the lighting control desk (e.g. ADB LIBERTY, FREEDOM or MENTOR desks) may operate simultaneously and there is no influence, since both systems work with different protocols. Alternatively the control desk may be connected to one of the DMX inputs of the
EURODIM Twin Tech cabinet. (Instead of using ArtNET protocol). The ETHERNET switch is connected with suitable communication cables (e.g. CAT5) to handle the dimmer information as well as the ArtNET communication. www.adblighting.com

6.1 Outputs to the loads
The cabling compartment with output terminals is on the right hand side. The load terminals are mounted next to the relevant module. The numbering is shown on self-adhesive labels.
These terminal blocks are suitable for cable sizes up to 10 mm². Special Adaptors are available for cables up to 25 mm² when installing 10 kW circuits. Grey = L ; blue = N.
The load cables must be sized in accordance with local regulations. Increased sizes may be required in order to reduce the voltage drop on the line to the luminaire. We suggest limiting the voltage drop to 3%.
Pay attention when fasting the load cables and tightening the terminal screws!
Do not over tighten the screws, do not use power tools (e.g. electric drill machines) – this may damage the terminals, and they will need to be replaced. This is a time consuming operation!
The data cables may follow the power cables on the condition that they are minimum
250 mm apart or in a separate shielded trunking (e.g. steel tube). Sound and video cables must be kept at a minimum distance of 500 mm from all power cables. If cables or ducts have to cross, then a crossing at right angles will reduce interferences.
6.2 Identification of the dimmers
The dimmers in a cabinet are identified by [slot number].[dimmer in the module].
Example: dimmer 2.3 is the third dimmer in the second module of the cabinet.
The preprinted label also shows the module’s supply phase. Custom labelling of the terminals is possible, e.g. the outlet or channel number.
6.3 Load terminals for 4 x 2.5 / 3 kW modules
Use all four pairs (L+N) of output terminals.
Please also see drawing N° 3500.01.650
6.4 Load terminals for 3 x 5 kW modules
Use only the first three pairs (L+N) of output terminals.
Do not use the fourth pair, labeled x.4.
6.5 Load terminals for 2 x 3 kW fluo modules
Each fluo dimmer comes with a dimmed output and a direct output on the second set of output terminals. This can be compared to a standard 4 x 3 kW module. All 4 circuits need to be patched to a DMX adress.
Your Fluo circuitry should be connected as follows:
- fluo dimmer 1 DIM: dimmed phase output on output e.g. 15.1 LINE
- fluo dimmer 1 DIM: dimmed neutral output on output e.g. 15.1 NEUTRAL
- fluo dimmer 2 DIM: dimmed phase output on output e.g. 15.2 LINE
- fluo dimmer 2 DIM: dimmed neutral output on output e.g. 15.2 NEUTRAL
- fluo dimmer 1 DIRECT: direct phase output on output e.g. 15.3 LINE
- fluo dimmer 1 DIRECT: direct neutral output on output e.g. 15.3 NEUTRAL
- fluo dimmer 2 DIRECT: direct phase output on output e.g. 15.4 LINE
- fluo dimmer 2 DIRECT: direct neutral output on output e.g. 15.4 NEUTRAL etc… www.adblighting.com
Installation manual - Page 24
Version 1.2
EURODIM TWIN TECH
Tripping the MCB of a fluo dimmer will disconnect the dimmer and its associated direct output. The direct output can be patched to an independent DMX channel.
Please also see attached drawing N° 3500.01.710
6.6 Load terminals for 10kW modules
Each 10 kW module is shipped with a special adaptor allowing the user to connect cables with up to 25mm² in diameter. The adaptor is screwed on to the edge of the cable bar and the four cables are connected to the terminals leading to the module.
Attention: All four cables must be connected!

EURODIM TWIN TECH
DMX and Ethernet terminals
All control signals are connected to the data input board PCB3031, located at the top of the right-hand cabling compartment.
PCB 3031
6.6.1 DMX Connection – type of cable
Use data cable with two twisted pairs + 1 conductor (can be from a third pair) + overall screen. Use data cable which is suitable for digital data transmission (EIA 485 / RS 485;
250kBaud). The data cable must meet the DMX512-A specification (ANSI E1.11 – 200x). Do not use audio cable for DMX, as this has the wrong capacitance and impedance and WILL
NOT reliably transmit DMX signals. The DMX signal uses fairly high frequencies, well above
1000 kHz.
Cable model LIYCY 3 x 2 x 0.35 + shield is suitable for this purpose. Two pairs are used for data transmission, and one conductor for the 0V (common) GND. The cable shield is connected to the PE.
Use of Ethernet cables for DMX
It is allowed to use Cat5 (or higher) STP and FTP Ethernet cable for DMX.
STP = shielded twisted pair.
FTP = foil twisted pair.
UTP = unshielded twisted pair.
WARNING: UTP Ethernet cable is not suitable for DMX.
Each EURODIM Twin Tech processor is equipped with two physical DMX inputs, and one
Ethernet port. For cabinets with optional ‘instant back-up’, each processor has its own independent data connectors.
Identification of the ports
The DMX ports of the top processor (Processor No. 1) are identified CPU1 –DMXA and
CPU1 –DMXB.
The DMX ports of the optional second processor (Processor No. 2) are identified CPU2 –
DMXA and CPU2 –DMXB.
Each DMX port has an Input and a through (link).
All pin numbering information is also indicated on the data port PCB3031. www.adblighting.com
Installation manual - Page 26
Version 1.2
EURODIM TWIN TECH
Screw connector in parallel with RJ45-for-DMX
For the convenience of the contractor, each physical DMX input has two types of connector in parallel: a pluggable screw terminal block, and a RJ45.
Use one, never use both.
The RJ45 are very convenient to use off-the-shelf STP cables for daisy-chaining between dimmer cabinets, and connection to RJ45 DMX patchfields.
6.6.2 Pin numbering
For standard DMX cables (2 pairs + screen), the connectors X1 through X8 are connected as follows:
1
2
COM
DMX-
0 Volt conductor (different from the screen) data 1- (DMX)
3
4
5
DMX+
AUX-
AUX+ data 1+ (DMX) data 2- (second data pair) data 2+ (second data pair)
6 PE screen in the DMX cable and connection to PE.
(For optimum EMC (Electro-Magnetic Compatibility) performance we recommend to separate
0V from PE)
All screens in all cables should be interconnected.
One end only should be connected to PE, to prevent an earth loop.
Pin configuration of the RJ45-for-DMX:
- pin 2
- pin 1
- pin 6
- pin 3
= data 1- (DMX)
= data 1+ (DMX)
= data 2-

6.6.3 DIP switches SW1 – termination of the DMX data lines
On PCB3031, SW1 switches 1 through 4 allow termination of the cabinets four DMX inputs.
To terminate CPU1-DMXA: set Switch 4 to ON.
To terminate CPU1-DMXB: set Switch 3 to ON.
To terminate CPU2-DMXA: set Switch 2 to ON.
To terminate CPU2-DMXB: set Switch 1 to ON.
DIP switches instead of link cables
On PCB3031, SW1 switches 5 and 6 connect “DMX1A Through” with “DMX2A In”.
Similarly, SW1 switches 7 and 8 connect “DMX1B Through” with “DMX2B In”.
This is a convenient and reliable alternative for short jumper cables. www.adblighting.com

8. PLUG IN MODULES
Before inserting the plug in modules in the cabinet, check that the 16 screws of the card cage
have been mounted and are fastened. (See chapter: 4 Contractors Compartment)
8.1 DimSwitch - Thyristor Technology
4 x 3 kW:
3 x 5 kW: this module contains 4 dimmers of 3 kW (13A) this module contains 3 dimmers of 5 kW (20A)
1 x 10 kW: this module contains one 10 kW dimmer (50A)
2 x 3 kW Fluo: this module contains 2 dimmer of 3 kW. The second output from the module supplies direct mains voltage (same phase) for the pre-heating of the fluorescent lamps, or for electronic ballasts. (See drawing below)
EURODIM Twin Tech DimSwitch modules are thyristor based, thereby eliminating the problems associated with the arcing of electromechanical contacts. Thyristor switching is at zero crossing. Contrary to many Solid State Relays, EURODIM Twin Tech DimSwitch modules have no ‘minimum load’ requirement.
8.2 Sine Wave Technology
4 x 2.5 kW: this module contains 4 dimmers of 2,5 kW
8.3 NON-DIM (Feed Through) modules
4 x 3 kW:
3 x 5 kW:
NONDIM module with 4 MCB’s of 13 A
NONDIM module with 3 MCB’s of 20 A
NON-DIM modules are direct feed through with no remote control. They cannot be switched from the lighting control desk.
8.4 Blank Panels
Panels are available to cover one or eight slots. These modules contain no dimmer.
8.5 Distribution of the dimmers over the phases
The supply phases alternate: next slot = next phase.
Modules 1, 4, 7, 10 etc. are supplied by L1.
Modules 2, 5, 8, 11 etc. are supplied by L2.
Modules 3, 6, 9, 12 etc. are supplied by L3.
The Module number appears on the right of the module.
8.6 Protections – types, number of poles
EURODIM Twin Tech is a standard cabinet to suit all installation types (IEC 60364). All configurations relay on the used plug in modules. www.adblighting.com
Installation manual - Page 31
Version 1.2
EURODIM TWIN TECH
Switch Off before unplugging
Since a dimmer module is rated above 32 A, hot patching of modules is forbidden by IEC EN 60439 and local regulations such as
NF C 15-100.
It is highly advised that one must switch off the dimmer protection
(MCB, RCD, RCBO) before withdrawing or positioning a module.
Additionally, the breaking of the contacts is sequential: first control, then power, and Earth last.
ADB has taken precautions that there is a minimal impact in case this rule is forgotten. When a module is plugged into the cabinet – first the protection earth is connected, then the supply and load supplies are connected and finally the control wiring connection is performed. This is to avoid that any sparks are pulled because the dimmer has been accidently fired.
8.7 Dimmer module protection by HRC fuse
Each power module is protected by a High Rupturing Capacity supply fuse (HRC, 63 A,
50 kA). This HRC fuse is located in the supply cabling compartment, on the left hand side of the cabinet.
Each individual circuit is supplied through an MCB or RCBO (MCB+RCD), in the module.
See next paragraph.
The protection in the main switchboard must be selected to ensure a proper fault current protection in relation with the line distribution short circuit current.
8.8 Dimmer protection by MCB
All ADB EURODIM Twin Tech power modules are standard equipped with MCBs per dimmer channel. The MCBs comply with EU rules and protect the wiring against overload and shortcircuit.
Please note that in unfavourable fault conditions, both the dimmer MCB and the HRC supply fuse may trip. In the event of severe damage to the thyristor modules, additional protection circuitry may intervene and will limit the fault to the dimmer cabinet.
The dimmer module should be removed or repaired first. Other elements should only be checked after the faulty dimmer is removed or repaired.
8.9 Residual Current Devices (RCD Ground Fault Protection)
EURODIM Twin Tech DimSwitch Thyristor modules are optionally available with an RCD per module, or an RCBO (MCB+RCD) per dimmer.
Warning: RCDs and common Neutral wires.
To solve a particular problem, or with some multicore lay-outs, you may consider using a single (large size) Neutral wire for a group of dimmers.
If the RCD protection is provided, then the following rule applies: the
“common neutral” should be common only to dimmers supplied by the same RCD. Failing to do so will invariably result in nuisance tripping of an RCD. www.adblighting.com

8.10 Installing Dimmer Modules
When inserting dimmer modules in to the crate please do so carefully. If the modules are forced into the crate, the connectors on the back may be damaged, or in the worst case the backplane PCB of the dimmer cabinet is damaged.
This will make a replacement of the large PCB necessary by dismantling the entire cabinet.

12. Appendix C – Power Supply for Thyristor Dimmers – Basic
Principles for Safe Electrical Design
The global performance of a dimmer system depends on the dimmers and also on its electrical supply system: supply transformer, supply cabling to the dimmers. Planners and electrical contractors may not be fully aware that some rules which are valid for resistive loads and sinusoidal currents (heating systems, incandescent lighting) do not apply to a phase-control dimmer system. With this Technical Information we try to provide some basic technical information about lesser-known aspects of a dimmer system.
12.1 Phase-control dimmers
The broad principles of phase-control dimmers are as follows.
• In an ideal world, the input voltage of a dimmer is a pure sine wave, with a frequency of
50Hz or 60Hz. A phase-control dimmer reduces the voltage by switching off part of the sine wave. So the shape of the dimmer output voltage is no longer sinusoidal: it contains the fundamental frequency (50Hz) and also harmonics (odd multiples of the fundamental:
150Hz, 250Hz, 350Hz ...).
• The output voltage of the dimmer is applied to the lamp. A lamp is comparable to a resistor, so the current has the same shape as the dimmer output voltage: part of a sine wave. So the current contains the same harmonics as the dimmer output voltage.
Note: this current flows through all parts of the system: lamp, dimmer, supply cables, switchgear, supply transformer.
12.2 Use ‘true rms’ voltmeters only
For a correct measurement of the output voltage of a dimmer, you need a ‘true rms’ voltmeter. Other – cheaper – voltmeters are useless. They give a false reading when used on the output of a dimmer. They assume that the voltage is a sine wave.
12.3 Current in the Neutral
– Sine Wave
Equipment requiring more than say 10 kW is usually supplied from a ‘star’ (wye) three-phase system: three live Lines and a Neutral (and Protective Earth PE). The Neutral is the common return conductor for the three Lines. The symbols for the Lines are L1, L2, L3; Lines are sometimes called Phases.
The following rules are well-known
1. When you use only one phase of a three-phase system, then the current in the Neutral is identical to the current in the Phase.
2. When an identical linear load is connected to all three phases, we speak of ‘a balanced load’. In that case the actual current in the Neutral is 0. Indeed the sum of three sine wave currents, equal in amplitude, 120
out of phase, is zero.
3. for sine wave currents, the max. current in the Neutral is equal to - or lower than - the max. current in any Line. For sine wave currents it is never larger.
IMPORTANT
Rule No. 1 is also valid for dimmers. It is a sufficient reason to forbid the use of supply cables with a reduced-size Neutral.
Rules No. 2 and No. 3 are NOT VALID for systems with phase-control dimmers! That is because their currents are not sine wave. www.adblighting.com
Installation manual - Page 51
Version 1.2
EURODIM TWIN TECH
12.4 Current in the Neutral
– Dimmer Systems
The harmonics in each of the three phase currents add up in the Neutral. The current in the
Neutral can be higher (!) than the current in any Line.
Rule with phase-control dimmers
The max. current in the Neutral is 125% of the max. current in the Line.
Warning
Never use supply cables with a reduced-sized Neutral conductor. This is dangerous and not compliant with standards / regulations.
125% in the Neutral
– how can I see this for myself?
You can see this with a simple set-up which requires only basic equipment:
- any 3-phase dimmer, e.g. an ADB MEMOPACK or MICROPACK, connected to a threephase star supply (3P+N+E)
- three identical lamp loads e.g. 1 kW luminaires
- a true rms A-meter with 10 A range, or with a 10 A current clamp
- a lighting control desk e.g. an ADB MIKADO or LIBERTY lighting control desk.
Connect the lamps to dimmers on three different phases; e.g. dimmers 1, 2, 3 for
MEMOPACK 15 or MICROPACK. Connect the A-meter to measure the current in the supply
Neutral.
Try out various combinations of level settings, including combinations of: one dimmer @ 100%, one @ 70%, one @ 0%.
You’ll find that the Neutral current can reach 125% of the lamp current.
12.5 Practical implications
12.5.1 Example No. 1
If you want certainty for continuous duty and any combination of dimmer levels, then a
CEE63 (3P+N+E) plug is suitable for a dimmer unit of max. 34kW. Larger loads can overload the N pin for some combinations of levels.
Formula: Watts = 3 x 230V x (63 / 1.25) A.
12.5.2 Example No. 2
A 3-phase dimmer cabinet rated for a Line current of 100A, will/should have Line busbars rated for minimum 100 Arms and a Neutral busbar rated for minimum 125A rms.
12.5.3 Example No. 3
Existing installation, and the existing cable has a half-size N. The circuit-breaker which feeds the cable is a type with four sensing devices: three in the Lines and one in the Neutral (rated for half current). The sensitivity of the MCCB has been trimmed to e.g. 200A for each Line, and consequently 100A for N.
- if the load is a ‘balanced load’ without dimmers, then I neutral is approx. 0, and this installation is suitable for 138kVA. Formula: 3 x 230V x 200A.
- if the load is a dimmer system, with luminaires nicely distributed evenly over the three phases, then you risk tripping for a power as low as 55kW. Indeed, for the most unfavourable combination of dimmer level settings, a total load above 55 kW can result in a Neutral current above 100 A. The trip device in the N-pole of the MCB could react.
Formula: worst case I neutral
= 55000W / 3 / 230V x 1,25 = 100A rms

12.6 Main transformer, cables, switchgear, busbar systems
The main transformer, the switchgear and the supply cables to the dimmer cabinet carry these non-sinusoidal currents.
This is valid for all phase-control dimmers (thyristor, triac, and some transistor dimmers), independent of brand and manufacturer.
A 'classic' recommendation is
- Inform the (future) supplier of the power transformer about the presence of thyristorcontrolled dimmers. He will select a suitable, type taking into account the extra losses due to the harmonics and the increased rms current in the N
- over-size the kVA rating of the main transformer; e.g. by 50% above the expected max. load.
12.7 Voltage distortion and 'short-circuit voltage' of the main transformer
Another aspect is that the harmonic currents cause distortion of the sine wave voltage. And with a distorted voltage wave-form, the dimmer electronics have a harder time to find the
'zero crossing'; unstable 'zero crossing' means that the light levels may flicker in some instances.
In more technical terms: the combination of the source impedance of the supply system
(transformer, switchboard, busbars, and supply cables) with the harmonic currents will distort the voltage at the input terminals of the dimmers.
Main transformer – recommendation
The transformer plays an important role. Its output voltage will show less distortion of the sine wave if the transformer's series impedance is low, i.e. if the transformer has a low 'shortcircuit voltage'. We recommend that the main supply transformer should have a 'short-circuit voltage' of max. 4%. Again, this recommendation is valid for all phase-control dimmers
(thyristor, triac, and phase-control transistor dimmers), of all brands and manufacturers. www.adblighting.com

13. Appendix D: Specification of Magnetic Circuit Breakers (MCB)
In this chapter we would like to discuss the dimension and types of MCB used for our dimmers. For 3 kW circuits ADB uses 13 A and for 5 kW circuits 20 A rated MCB with C
Curve. Below we will explain why we use these values; it has been carefully designed in our product, for your maximum safety and protection.
Now following the laws we have all learned:
P(Watt) = U(Volts) x I(Amperes)
By applying this formula and a Voltage of 230 V you will receive 2.990W
3
(13 A) and 4.600 W
(20 A) maximum loads. At first sight this may be not sufficient – be reassured this has been well thought of and is fully intentional as we will explain.
ATTENTION: This formula may not be applied as simple as that because there is a second factor to keep in mind and that is the curve of the selected line protection device. There are many different curves MCB may have depending on the application (Motors, General
Household applications etc…)
“C” curve type protection is used exclusively for lighting applications. Below you can see the graph depicting the current passing through the MCB. If you look carefully to the curve, you will notice that the MCB will hold the factor of minimum 1.13 (maximum 1.45) for an infinite amount of time.
The 13A nominative MCB will hold min. 14.69A (or 3.38kW) and the 20A nominative MCB will hold min. 22.6A (or 5.2kW) over an infinite amount of time.
ADB digital dimmers perform intelligent soft-starts when flashing the circuit by the lighting console to full. This clever programming algorithm of our digital dimmers prevents the MCB from tripping and helps you to save lamp life by inflicting less stress on the lamp filament!
Attention: But one must never plug in cold tungsten halogen loads in a dimmer (or even an undimmed circuit) at 100% Full. Large tungsten filament lamps may appear as short-circuit to any MCB exceeding by far the short-circuit current of 10x nominative value.
Result: the MCB will trip for sure!
Therefore always make sure that a dimmer circuit is turned off, or at least at a very low value when hardplugging luminaires.
Additional Safety Features for extremely high short circuit values:
ADB exclusively features 63A HRC fuses protecting the modules against any internal shortcircuit and improving the ICC value of the cabinet to 50kA. This is an additional safety feature may not be often found in competitor products.

All calculations are done with a supply current of nominative 230V in these examples.
