The installation and operation of this luminaire are subject to national
safety regulations.
Installation and commissioning may only be carried out by a qualified
electrician.

Installation
LED are high-quality electronic components!
Please avoid touching the light output opening of the LED directly during
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 three adjustable
wedge-shaped claws. Installation in concrete ceilings:
To accommodate the luminaire and the external power supply unit we recommend
using the installation housing 10 443.
Installation in suspended ceilings:
A recessed opening of ø 202 mm with a minimum installation depth of 140 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.
If these terminals are not assigned, the luminaire will work with full light
output.
Pull cover ring (magnetic) off the installation ring of the pivoting housing.
Connect plug part of the luminaire with power Push external LED power supply
unit and luminaire housing into the ceiling cut-out.
Tighten guide screws.
When tightening the screws, the fixing claws must swivel onto the inside of
the suspended ceiling. The luminaire is fixed.
When undoing the guide screws, the fixing claws swivel back and the luminaire
can be removed.
Adjustment of the direction of radiation:
Undo both hexagon socket head screws and remove transportation lock. Adjust
tilt angle and beam direction of the LED. Tighten latching screw.
Mount the cover ring onto installation ring of the housing (magnetic).
