• 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 (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).

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 firmly against the stop.
• The desired half beam angle of the luminaire can be set by turning the adjustment ring with the marked cam.
• The range of the half beam angles on the trim ring includes a tolerance of ± 2.5°.
