Installation

Luminaire housing must not be installed in heat-insulating material. LED are high-quality electronic components! Please avoid touching the light output opening of the LED directly during installation or relamping. The recessed opening will be covered by the frame of the luminaire. Fixing of the luminaire is achieved by using 2 adjustable wedge-shaped claws.

Installation into false ceilings
A recessed opening of ø 68 mm is necessary to accept the luminaire housing. Free space depth min. 60 mm (see sketch). The claws catch the panel from the reverse side. If the minimum thickness of the panel is less than 3 mm it must be reinforced from the reverse side. The maximum thickness of the panel must be no more than 20 mm. Remove cover of the external LED power supply unit. Loosen set screws of cable strain relief. Tightening zone for strain relief: max. Ø 12mm. Connecting terminals for mains supply: max. 2,5@. Terminal DALI: max. 1,5@. Strip the wires 6 mm. Lead mains supply cable through the cable strain relief and fix set screws. Make an electrical connection. The connection of the control cables is achieved by means of both leads marked with – DALI. In case these leads are not used the luminaire will be operated at full light output.

Close case cover of the external LED power supply unit and press it until it is locked. Push external LED-power supply unit and luminaire housing into ceiling cut-out. Luminaire housing and external LED power supply unit must not be installed in heat-insulating material. Hand-tight screws of claw fasteners evenly.
