BEGA 85112K3 Compact Downlight

Product Information

This luminaire is designed with electronic components that are protected against overvoltage by DIN EN 61547. For additional protection against transients, it is recommended to use separate overvoltage protection components available on the manufacturer’s website.

It is important to avoid contact with the inner surface of the luminaire reflector to maintain the special stray light-minimizing properties of the nano-coating.

Specifications:

Lamp Module connected wattage: 25.2 W
Luminaire connected wattage: 28 W
Rated temperature: 25 – 35°C
Ambient temperature: max 25 – 35°C

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 by DIN EN 61547.
To achieve 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 to permanently protect the special stray light-minimising properties of the nano- coating.

Installation

Screw the floodlight G½ threaded connection firmly into the on-site G½ female thread or BEGA accessory.
G½ threaded connection torque = 40 Nm.
Secure the screw connection from loosening on site (if provided with locking screw S, see fig. A).
Check the earth conductor connection between the G½ threaded connection and the on-site G½ female thread.

$BEGA-85112K3-Compact-Downlight-Fig- $2$$

Adjust floodlight:
Undo the hexagon socket screw (wrench size 5 mm) and hexagon nut (wrench size 30 mm) and set the desired beam direction.

Torque:

Hexagon socket screw = 7 Nm
Hexagon nut = 35 Nm
Secure bolted connection Gß against loosening by tightening the hexagon socket screw (wrench size 2 mm) (see sketch B, C).
The electrical connection must be carried out with matching protection class and safety class, strain-relieved, with suitable connection terminals (not included in the scope of delivery) at the luminaire power supply cable.
Note the correct configuration of the main supply cable.
Make mains supply connection at the brown (L), blue (N) and green-yellow lead ( ).
The connection of the control cables is achieved using both leads marked with DALI.
In case these leads are not used the luminaire will be operated at full light output.

Cleaning And Maintenance

Clean the luminaire regularly with solvent-free cleansers from dirt and deposits.
Do not use high-pressure cleaners.

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 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 the 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.
The 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.
