- Mounting Options Modul Q-Series
-
Luminaires in the Modul Q series can be mounted in a variety of ways. (Example Modul Q 36)
Mounted luminaire for directing mounting
The luminaire mounting plate can be mounted easily and directly on suspended ceilings. The luminaire is fastened to the mounting ring via a unique magnetic support system, making it easy to align and adjust. A further installation option is to mount a magnetic plate on a standard in-wall junction box. The luminaire can also be fastened here magnetically.
Mounted luminaire for cavity mounting/HaloX-O
The cavity or HaloX bracket is mounted without tools in the recess in the suspended ceiling or in the fitting after the converter has been placed there. The converter cable is guided through the bracket and connected to the luminaire. The luminaire is clipped magnetically to the bracket.
Mounted luminaire for installation with surface-mounted housing
1) Surface-mounted housing for integrated converter:
Use this version if, for example, a 230V ceiling outlet is available. First of all, the housing is screwed to the ceiling. The integrated converter is connected to the ceiling outlet. The magnetic plate is then screwed to the stud bolts in the housing. The luminaire is clipped to the steel plate.
2) Surface-mounted housing without converter:
This version is appropriate if, for example, a 24V ceiling outlet is available, the converter can be placed in the ceiling or if the converter is not installed near the luminaire. The surface-mounted housing serves as a connection space. First the housing is screwed to the ceiling. The 24V connection is connected to the LED luminaire. The magnetic plate is then screwed to the stud bolts in the housing. The luminaire is clipped to steel plate.
- Other Methods of Mounting
-
Mounting Zen On
1) The Zen On can be mounted directly on an in-wall junction box – as used for switches/sockets. The converter is simply placed in the (existing) in-wall junction box.
The luminaire is screwed directly onto the wall mounting box. Alternatively, the luminaire can be screwed to the wall/cavity wall in the usual way.2) If a 24 V output is available, the Zen On can be mounted as shown here.
Situation for flush mounting in void
Thanks to their extremely compact design, the Modul Q36 In and Modul Q 64 In luminaires can be mounted almost flush in a suspended ceiling. Installation depth is minimal.
- Connecting LED Luminaires

Connecting up
Please use only converters with 24 V direct voltage for connecting up Nimbus LED.next luminaires. Standard transformers may not be used. When connecting luminaires to the converters please make sure the polarity (+/-) is correct. If you have more than one LED.next luminaire, they may only be connected in parallel (see sketch).

-
Cable lengths
The converter can be installed some distance away from the luminaire. However, the cable cross-section must of such a size that at least 23V reach the luminaire.
This table shows the maximum cable lengths between a LED luminaire/luminaires and the converter. The following applies as a general principle: The higher the LED output, the higher the cable cross-section must be.
Example: With a 24 W LED.next luminaire and a 1.0 mm² cable, the maximum cable length is 28 m.Possible cable lengths between luminaire(s) and converter:
W 0,75 mm² 1,0 mm² 1,5 mm² 2,5 mm² 3 W 168 m 224 m 336 m 560 m 6 W 84 m 112 m 168 m 280 m 12 W 42 m 56 m 84 m 140 m 24 W 21 m 28 m 42 m 70 m 60 W 8,3 m 11,1 m 16,7 m 27,8 m 100 W 5 m 6,7 m 10,1 m 16,8 m - Activation Capability EIB/KNX

Controlling LED luminaires via an EIB/KNX-BUS
The EIB/KNX signal is converted to a DALI/KNX bus signal using a gateway, thus controlling the DALI dimmer. Only one converter may be used for each dimmer.
- Dimming
-
Dimming poses no problems at all with Nimbus LED luminaires. The 24 V constant voltage requires special Nimbus dimmers with pulse width modulation (PWM). Pulse width modulation is beneficial in terms of energy, as it works with virtually no power loss. A number of dimmers can be connected to one Nimbus converter. The dimmer and converter cable determines the maximum number of LED luminaires that can be connected to each dimmer. Standard dimmers or (reverse) phase control dimmers may not be used under any circumstances.
Dimming control with rotary potentiometer
The Nimbus LED.next dimmer (003-906) only works with the accompanying rotary potentiometer. The 2-pole cable can be extended.
Dimming control with potentiometer or 1-10 V controller
Activation occurs via a 1 volt (minimum brightness) to 10 volt (maximum brightness) interference-proof DC signal. All control cables between system components must be designed for mains voltage of 230 volts. Make absolutely sure that the + and – wires of the 1-10V control cable do not get mixed up. Simple wiring with 5-pole standard cables is possible. Separate installation or shielded control cables are not necessary (according to DIN VDE 0100 520 section 6, main circuits and their associated auxiliary circuits may be installed together, even if the auxiliary circuits carry less voltage than the main circuits).
Dimming control with push button
A standard push button in the wall is used for dimming (designed as a N.O. contact). 5-core wiring able to withstand mains voltage must be in place between the push button and the luminaire (converter). These 5 conductors can be grouped in one cable. One short press on the button switches the luminaire on or off; holding the button down makes the light brighter or dimmer.
Dimming control with DALI-BUS
DALI (digital addressable lighting interface) is a standard used by all manufacturers for digital activation. Individual luminaires are assigned a digital address and can, for example, be grouped into switching or dimming groups and can be rearranged at any time. An installation which has already been set up need not be changed for this purpose. A DALI control unit is a central element in the set up and can be activated, for example, by radio-controlled switches, ambient light sensors or programmable remote control units. Any 5-core cable able to withstand the mains voltage can be used to connect a DALI dimmer (e.g. 5-core NYM). Activation then occurs via two wires from the DALI control unit. Attention need not be paid to the correct polarity of the DALI control cables.
Lighting control with DALI can also be integrated in complex building control systems. - Problem Solving
-
The following diagrams show what may go wrong when installing LED luminaires.
Attention must always be paid to the correct polarity when connecting LED luminaires ( positive pole; - negative pole).
Two or more LED luminaires may not be connected in series.
Two or more converters may not be connected in parallel at the output.
Two or more converters may not be connected in series at the output.
Normal transformers which supply alternating voltage may not be connected to LED luminaires.
Always connect PWM dimmers between converter and LED luminaires. (PWM dimmers dim the 24 V DC connection).
LED luminaires cannot be dimmed with a (reverse) phase control dimmer.
