Installation

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!

IMPORTANT:
The mounting plate must be mounted so that the protective conductor screws of the mounting plate are parallel with the surface to be illuminated.
Pay attention to the required direction of the light emission when arranging the mounting plate
Installation

If the light is to be emitted from the luminaire in the opposite direction, the mounting plate must be rotated by 180°.

Lead the power connecting cable through the mounting plate.
Ensure correct directionality towards the area to be illuminated.
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 (1) of the mounting plate.
Establish the earth conductor connection to the luminaire housing (plug contact).
Push silicone hoses over connecting wires and make the electrical connection at the terminal 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
Installation

IMPORTANT:
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 as far as it will go.
The exact alignment is achieved by turning back the luminaire by max. 30°.

Cleaning · Maintenance

Clean luminaire regularly with solvent-free cleansers from dirt.
