Installation in concrete ceilings:
To accommodate the luminaire and the external power supply unit we recommend using the installation housing 10 444.

Installation in suspended ceilings:

• A recessed opening of ø 240 mm with a minimum installation depth of 160 mm is required.
• The external power supply unit requires a minimum of 90 mm clearance above the ceiling (see drawing).
• The claws grip behind the ceiling cladding.
• The minimum thickness of the ceiling cladding is 5 mm.
• If the thickness is less, and if installation is to be effected in plasterboard ceilings, the back of the ceiling cladding must be reinforced in the region of the claws.
• The electrical connection must be made on site in the appropriate safety class on the LED power supply unit connecting cable. A distribution box must be used.
• Ensure the correct assignment of the connecting cable. Establish the mains connection on the brown (L) and blue (N) wires.
• The two connecting terminals marked DA, DA are provided for digital control purposes.
