Prior to installation, please note:
To ensure correct mounting and installation of the luminaire, the luminaire base must be installed on an even surface.
IMPORTANT : For installation and dismantling of the luminaire top, a clearance of 60 mm is required on each side in the area of the two lateral luminaire caps (hexagon socket screw, wrench size 1.5).

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 base from its packaging. Pass the power connecting cable through the cable entry into the luminaire base. Drill mounting holes into the mounting surface – spacing 900 x 81 mm
Attach the luminaire base on the installation surface using the material supplied or other suitable mounting material.
Shorten the power connecting cable to max. 150 mm and strip the coating to 100-120 mm. Carefully remove the luminaire top from its packaging and guide the back side against the luminaire base.
Establish earth conductor connection and make the electrical connection to the terminals. For digital control please use the connecting terminal DA, DA.
In case this terminal is not used the luminaire will be operated at full light output.

NOTE : To make it easier to secure the luminaire top on the luminaire base, it is helpful to pre-shape the rigid connecting wires – see diagram.

IMPORTANT : To guarantee the luminaire’s safety class, make sure that the pre-shaped connecting wires are within the rectangular sealing area and not protruding out of it.
Guide the mounting sockets of the luminaire top exactly onto the installation bolts of the luminaire base – in the process, check the sealing area of the connecting wires.
Applying even pressure on both sides, lock together the luminaire top and luminaire base. Screw in the two hexagon socket locking screws (wrench size 1.5) approximately 1.5 mm deeper than the cover surface.
This ensures a secure connection between the luminaire top and luminaire base.

Dismantle the luminaire in reverse order. Loosen the hexagon socket locking screws. Insert a screw driver into the flat opening at the edge of the two front covers and lift the luminaire top on both sides away from the luminaire base against the resistance of the locking mechanism.

Replacing the LED module
The designation of the LED module is noted on a separate label in the luminaire or on the underside of the specific LED module.
It is also listed in the spare parts overview at the end of these instructions for use.
The light colour and light output of BEGA replacement modules correspond to those of the modules originally fitted. The module can be replaced by a qualified person using commercially available tools.
Disconnect the system from the power supply.

Unscrew both side hexagon socket locking screws (SW 1.5) by about 3 mm from the covers of the wall luminaire.
Insert a screw driver into the flat opening at the edge of the two front covers and lift the luminaire top on both sides away from the luminaire base against the resistance of the locking mechanism.
Remove the wires on the power connecting cable from the terminals marked (L), (N), DA DA.
Position the luminaire top on a soft surface (e.g. on both thighs).

Please note:
The side cover of the luminaire in the area of the connection terminal is braced by a spring mechanism.
The screw of the spring mechanism is accessible via the rectangular opening on the back of the luminaire top.

IMPORTANT : The following work step requires the force of both hands in order to evenly exert pressure on the screw and counterpressure on the spring mechanism! While you loosen these screws, press down with your hand from the top on the Torx screwdriver (TX 20) and generate lateral counterpressure ( ! ) on the screwdriver at the same time using several fingers of the other hand in order to slowly relieve the spring force.

Pull the side cover off the synthetic cover in the area of the rectangular recess and unhook it. Pull the synthetic cover off the remaining cover and carefully guide it away over the electrical LED unit.
Remove the LED module.
Install the replacement LED module.
Follow the installation instructions for the LED module.
In case of a defect, the PSU can be replaced in this work step.
Carefully guide the synthetic cover over the LED unit.
Make sure not to damage the LED module.
A defective luminaire cover must be replaced.

The LED support profile is equipped with a locking device.
This locking device must be inserted with its insertion opening first over the latching sleeve of the luminaire top (in the area of the rectangular opening).
Press the side cover of the LED support profile into the synthetic cover of the luminaire top. Make sure the gasket is correctly seated.

NOTE : In order to install the second side cover safely, it is recommended to place the luminaire top on a soft surface (e.g. on both thighs).
To apply counterpressure on the first side cover (of the LED support profile), a 2nd person is helpful.

Push the screw of the spring mechanism as far as it will go in the direction of the cover to be braced.
Pick up the side cover and guide it with the inner hole over the suspension pin of the spring mechanism.
Insert the cover and press it sideways against the synthetic cover of the luminaire top as far as it will go.
Make sure the gasket is correctly seated.
As before, the following work step again requires the force of both hands in order to evenly exert pressure on the screw and counterpressure on the spring mechanism!

Guide the Torx screwdriver (TX 20) onto the screw of the spring mechanism.
Press down with your hand from the top on the Torx screwdriver and generate lateral counterpressure ( ! ) on the screwdriver at the same time using several fingers of the other hand.
Tension the spring against the tensile force until the stop is reached.
Tighten the screw in the end position.
Make the electrical connection and reinstall the wall luminaire in reverse order as described under “Installation”.

Cleaning · Maintenance
Clean luminaire regularly with solvent-free cleansers from dirt.
