installation or revamping.
The recessed opening is covered by the frame of the luminaire housing.
Fixing of the luminaire in the structure is achieved by using two adjustable
claws.

A recessed opening of ø 128 mm with a minimum installation depth of 105 mm is
required.
The external power supply unit requires a minimum of 90 mm clearance above the
ceiling.
The claws grip behind the ceiling cladding.
The minimum thickness of the ceiling cladding is 12 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.
