Installation
A separate power supply unit is required to operate the luminaire. For connection to external LED-power supply unit – accessory 13 144 or 13 169 – the luminaire is equipped with a 2-pin connector. Note operating instructions of the LED-power supply units. LED are high-quality electronic components! Please avoid touching the light output opening of the LED directly during installation or relamping. The recessed opening is covered by the frame of the luminaire housing. Fixing of the installation housing in the recessed opening is achieved by using two adjustable springs.
Installation into inserted ceilings:
A recessed opening of 146 mm is necessary to accept the installation housing.
Recessed depth min. 105 mm. Compress the fastening springs of the installation
housing against their spring pressure on both sides towards the housing and
slide the installation housing into the recessed opening. The fastening
springs catch the ceiling panel from the back side. Minimum thickness of the
ceiling panel is 5 mm. If minimum thickness of the panel is less than 5 mm it
must be reinforced from the reverse side. Maximum thickness of the ceiling
panel must be no more than 25 mm.
Push the enclosed threaded rods through the two inside openings of the
installation housing and guide the clamping angle of the threaded rods
downwards onto the suspended ceiling. Clip the threaded rods into their guide
grooves and screw them in by hand as far as possible. Fix in end position with
screwdriver (TX 10). This clamp fixing prevents the installation housing from
turning and dropping. Connect to the LED power supply unit. Route the LED
power supply unit through the installation housing and place it in the
suspended ceiling. Connect the 2-pin plug connector between luminaire and
external LED power supply unit.
Press together the two internal fixing sliders inside the luminaire housing.Push the luminaire housing to the end of the installation housing and then release the fixing sliders. This mechanism ensures that the luminaire housing sits securely inside the installation housing. Fix crystal glass with cover ring and dispersing lens into the luminaire housing by turning it clockwise.
