Installation
LED are high-quality electronic components! Please avoid touching the light
output opening of the LED directly during installation or relamping.
Remove mounting plate from the luminaire housing. Unplug the earth conductor
connection (plug contact).
Please note:
If the luminaire is to be mounted onto a metallic, electroconductive
surface, it is mandatory to make sure that the mounting surface is connected
conductive to the earth conductor of the luminaire! Lead the power connecting
cable through the
mounting plate. Fix the mounting plate with enclosed or any other suitable
fixing material onto the mounting surface.
Establish the earth conductor connection on the earthing screw ( ) of the
mounting plate. Establish the earth conductor connection to the luminaire
housing (plug contact). Push silicone sleeves over the lines and establish the
electrical connection to the terminals marked (L) and (N). 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.
MPORTANT:
To ensure secure connection, the luminaire housing must be positioned
precisely in relation to the mounting plate. Make sure that the vertical bar
inside the luminaire housing is positioned precisely in the area of the
mounting hole on the long bar of the mounting plate. Press the luminaire
housing firmly against the mounting plate and turn it clockwise firmly against
the stop.
Screw enclosed trim ring with attached reflector into the luminaire housing by turning it clockwise.
