However, for additional protection against transients, it is recommended to use separate overvoltage protection components, which can be found on the manufacturer’s website. The product features LED technology, and it is important to avoid touching the light output opening of the LED directly during installation or relamping.

Product Usage Instructions

Ensure that the luminaire is installed and operated in compliance with national safety regulations.
Have a qualified electrician carry out the installation and commissioning.
Do not make any modifications to the luminaire without proper authorization from the manufacturer.
For additional protection against transients, consider using separate overvoltage protection components available on the manufacturer’s website.
Avoid touching the light output opening of the LED directly during installation or relamping.
When installing the luminaire in heat-insulating material, ensure that the rated temperature and ambient temperature are within the specified limits.
Refer to the module designation for information on connected wattage, colour temperature, colour rendering index, module luminous flux, luminaire luminous flux, and luminaire luminous efficiency.
For any accessories required, request separate instructions for use.
If any spare parts are needed, refer to the provided part numbers for spare glass, LED power supply unit, LED module 3000 K, and reflector.

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.

Installation

LED are high-quality electronic components! Please avoid touching the light output opening of the LED directly during installation or relamping.
The recessed opening is covered by the frame of the luminaire housing.
Fixing of the luminaire in the structure is achieved by using three adjustable wedge-shaped claws.

Installation in concrete ceilings:
To accommodate the luminaire and the external power supply unit we recommend using the installation housing 10 443.

Installation in suspended ceilings:

A recessed opening of ø 202 mm with a minimum installation depth of 140 mm is required.
The external power supply unit requires a minimum of 90 mm clearance above the ceiling (see drawing).
The claws grip behind the ceiling cladding. The minimum thickness of the ceiling cladding is 5 mm.
If the thickness is less, and if installation is to be effected in plasterboard ceilings, the back of the ceiling cladding must be reinforced in the region of the claws.
The electrical connection must be made on site in the appropriate safety class on the LED power supply unit connecting cable. A distribution box must be used.
Ensure the correct assignment of the connecting cable. Establish the mains connection on the brown (L) and blue (N) wires. 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.
Pull cover ring (magnetic) off the installation ring of the pivoting housing.
Connect plug part of the luminaire with power supply unit.
Push external LED power supply unit and luminaire housing into the ceiling cut-out. Tighten guide screws.
When tightening the screws, the fixing claws must swivel onto the inside of the suspended ceiling. The luminaire is fixed.
When undoing the guide screws, the fixing claws swivel back and the luminaire can be removed.

Adjustment of the direction of radiation:
Undo both hexagon socket head screws and remove transportation lock. Adjust tilt angle and beam direction of the LED. Tighten latching screw.
Mount the cover ring onto installation ring of the housing (magnetic).
