Product Information

Safety	The installation and operation of this luminaire are subject tonational safety regulations. Installation and commissioning mayonly be carried out by a qualified electrician. The manufactureraccepts no liability for damage caused by improper use orinstallation. If subsequent modifications are made to theluminaire, the person responsible for these modifications shall beconsidered the manufacturer.
Overvoltage Protection	The electronic components installed in the luminaire areprotected against overvoltage in accordance with DIN EN 61547. Toachieve an additional protection against e.g. transients, etc. werecommend separate overvoltage protection components. You can findthem on our website at www.bega.com.
Installation	Luminaire housing must not be installed in heat-insulating material. 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 two adjustable claws. Installation in concrete ceilings: To accommodate the luminaire and the external power supply unit we recommend using the installation housing 10 441. Installation in suspended ceilings: A recessed opening of ø 128 mm with a minimum installation depth of 105 mm is required. The external power supply unit requires a minimum of 90 mm clearance above the ceiling. The claws grip behind the ceiling cladding. The minimum thickness of the ceiling cladding is 12 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. Luminaire housing and external LEDpower supply unit must not be installed in heat-insulating material. 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).
