Notice prior to installation:
The installation of the luminaire must be carried out by 2 persons!
When mounting the luminaires, it must be ensured that the ceiling surface has
sufficient load-bearing capacity.
Please check the secure mounting of the luminaires after installation.
Installation
LED are high-quality electronic components!
Please avoid touching the light output opening of the LED directly during
installation or relamping.
Remove the luminaire housing (installation housing) from its packaging.
Depending on on-site requirements, the steel wire affixed to the top of the
luminaire housing can be secured to a non-flammable building component (see
drawing).
Cover the recessed opening with the stop ring of the luminaire housing.
The luminaire housing is then fixed in the recessed opening via four
adjustable springs.
IMPORTANT:
Place the four protective adhesive foils in the areas where the fastening
springs will be screwed into the luminaire housing. This will protect the
inner surface of the luminaire housing during installation in the recessed
opening.
Installation into inserted ceilings:
A recessed opening of 885 mm with a minimum depth of 205 mm is required.
Push luminaire housing into the ceiling cut-out and tighten evenly the hexagon
socket head screws (wrench size 4) of the four mounting springs.
The mounting springs catch the ceiling facing from the back side. The minimum
thickness of the panel must be 12 mm and the maximum thickness 25 mm. If the
ceiling facing has a thickness of less than 3 mm, the facing thickness in the
region of the mounting springs must be increased from the back side.
Pass the power connecting cable through the opening in the installed luminaire
housing.
Unpack luminaire.
IMPORTANT: In order to prevent deformation caused by the luminaire’s own
weight, do not place it on its curved synthetic cover when outside the
packaging!
Remove the adhesive protective foils and replace them with an offset below the
four openings on the edge of the housing.
Position the luminaire in such a way that the LED power supply unit at the
back of the luminaire is facing up.

Guide the LED power supply unit through the opening of the luminaire housing
and position it on the suspended ceiling.

taking care not to damage the coloured surface.
The four retaining plates of the luminaire must fit exactly into the four
openings on the top edge of the housing. Secure the luminaire by lifting it
over the locking pins and with a twist to the right until you feel a stop.
