Safety

The installation and operation of this luminaire are subject to national safety regulations.
Installation and commissioning may only be carried out by a qualified electrician.
The manufacturer accepts no liability for damage caused by improper use or installation.
If subsequent modifications are made to the luminaire, the person responsible for these modifications shall be considered the manufacturer.

Overvoltage protection

The electronic components installed in the luminaire are protected against overvoltage in accordance with DIN EN 61547.
To achieve an additional protection against e.g. transients, etc. we recommend separate overvoltage protection components.
You can find them on our website at www.bega.com.

Please note:
Contact with the inner surface of the luminaire reflector should be avoided in order to permanently protect the special stray lightminimising properties of the nano-coating.

Installation

LED are high-quality electronic components!
Please avoid touching the light output opening of the LED directly during installation or relamping.

Undo hexagon socket head screws (wrench size 3 mm) at the mounting box and remove mounting plate.
Pass the power connecting cable through the cable entry in the mounting plate.
Note position of application of the mounting plate “arrow down”.
Fix the mounting plate with enclosed or any other suitable fixing material onto the mounting surface.
Be sure to use the gasket rings supplied.
Make earth conductor connection.
Push silicone sleeves over the lines and make electrical connection to terminal (plug connection).
For digital control please use the 2-pole plug connector DA, DA.
In case this connector is not used the luminaire will be operated at full light output.
Push plug into coupler as far as it will go.
Make sure that gasket is positioned correctly.

Adjustment of beam direction:
Undo joint screw (hexagon socket head
wrench size 5 mm) and set the desired beam
direction.
Tighten the joint screw.
Torque = 7Nm.

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.
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.
Open the floodlight:
Loosen the back locking pin (hexagon socket wrench size 2) in the trim ring.
Remove the trim ring along with the safety glass and reflector by twisting it anti-clockwise.
Please note:
Contact with the inner surfaces of the louvres and luminaire reflector should be avoided in order to permanently protect the special stray light-minimising properties of the nano-coating.
Grasp the louvres from the outside and lift them out. Loosen the three mounting screws (Torx drive T20) and lift the lens holder (with the loosely inserted lenses) upward horizontally out of the housing.
Replace LED module.
Please follow the installation instructions for the LED module.
Install in reverse order.
When installing the lens holder, make sure that the LED connecting cable is not pinched.
Inspect and, if necessary, replace the luminaire gaskets.
Defective glass must be replaced.
Place the trim ring with glass and reflector on the floodlight housing so that the notches in the trim ring and luminaire housing sit on top of each other.
Twist on the trim ring clockwise as far as the stop. Screw in the locking pin.
