All oneLED wall- and ceiling luminaires were designed for a direct installation on a in-wall junction box. If an on-wall installation is required, installation frames are available as an accessory for the respective designs. Even a cavity version of the direct ceiling luminaire can be provided.
Mounting on an in-wall junction box
|For flush-mounting installation||e.g. Kaiser-Elektro* 1555-04|
|For cavity wall installation||e.g. Kaiser-Elektro* 9064-01|
|For fire protection installation F90**||e.g. Kaiser-Elektro* 9464-01|
|For concrete installation||e.g. Kaiser-Elektro* 1260-40|
* Or of another manufacturer with the same specification.
** Only in combination with installation frame22.
All oneLED suspension luminaires are delivered with a standard suspension length of 160cm. The power supply cable is 240cm long. Of course, suspension as well as power supply can be shortened during, respectively after installation. Longer suspension ropes and/or power supply cable are available as accessories.
If you want to use the integrated dimming unit in the canopy, two different control systems are possible:
|Control via PUSH||It has to be observed that the three-core power supply cable (230V AC) has to be extended by 2 additional wires (for main voltage) to the push-button (refer to chapter dimming).|
|Control via 1…10V
|It has to be observed that addionally to the three-core power supply cable (230V AC) a further two-core cable is laid to the rotary potentiometer (refer to chapter dimming).|
If the suspended luminaire should be installed at a suspended ceiling, a cable outlet box can be mounted on a junction box instead of the canopy. The required converter as well as the dimming unit can be centrally placed in the building or within the ceiling, accessible by an access hatch (refer to chapter wire lengths and cable cross-sections).
All oneLED luminaires are connected to parallel 20-24V constant voltage.
The required converter can be installed as follows:
|Decentralised||The converter needed for an individual operation of a oneLED can be installed directly in the in-wall junction box or on-wall in combination with an installation frame48. Please be aware that this typ of installation allows no space for a dimming unit.|
|Centralised||The converter needed for one or more oneLED luminaires can be centrally installed in the room or building. Please consider cable cross-sections as well as the maximum wire lengths allowed.|
Dimming oneLED luminaires is without difficulties possible.
Specially designed puls width modulation dimming units (PWM) are connected between the 24V power supply and the oneLED luminaire. With one 24V power supply you can connect and operate one or more dimming units simultaneously.
However it has to be observed that those oneLED luminaires connected to one dimming unit do not exceed the maximum power of the PWM dimming unit, as well as all connected oneLED luminaires do not exceed the maximum power of the converter.
The cross-section of the cable between converter and oneLED luminaires has to be so dimensioned, that a minimum supply voltage of 20V energises the luminaire.
The following table indicates at which total power (against the cable cross-section), which wire lengths can be realised.
|Power||0.75 mm²||1.00 mm²||1.50 mm²||2.50 mm²|
|12 Watt||150 Meter||200 Meter||300 Meter||500 Meter|
|18 Watt||100 Meter||135 Meter||200 Meter||335 Meter|
|20 Watt||90 Meter||120 Meter||180 Meter||300 Meter|
|50 Watt||35 Meter||45 Meter||70 Meter||120 Meter|
|70 Watt||25 Meter||35 Meter||50 Meter||85 Meter|
|100 Watt||15 Meter||20 Meter||35 Meter||60 Meter|
|150 watt||5 Meter||10 Meter||20 Meter||30 Meter|
|240 watt||5 Meter||10 Meter||15 Meter|
For EMC reasons, a ferrit core should be installed behind the dimming module at dimmed systems with a wire length from 10 meters on.
