Overvoltage Protection
Electronic components are protected against overvoltage according to DIN EN 61547. For additional protection against transients, separate overvoltage protection components are recommended (available on the BEGA website).
Safety
National safety regulations must be observed for installation and operation. Installation and commissioning must be performed by a qualified electrician. Fuse protection via a residual current circuit breaker is recommended. BEGA is not liable for damage caused by improper use or installation. Modifications made by others render them the manufacturer.
Installation and Mounting
Notice Prior to Installation: A proper foundation is required to withstand the maximum pressure load of 3,000 kg (~30 kN). The foundation must be on firm subgrade. The luminaire housing must be concreted in for stability.
Installation: Position the luminaire housing on the foundation and fix it securely. Electrical connection must be made on-site according to protection class and safety class requirements. Distribution boxes 70 730 or 71 053 are recommended for connection. Ensure correct wiring: Phase to brown wire (L), Neutral to blue wire (N), and Earth to green-yellow wire (?). After ground work, remove the protective foil from the luminaire cover. Tighten screws in the trim ring evenly crosswise to a torque of 4 Nm.
Cleaning and Maintenance
Initial cleaning after installation is necessary to remove building dust, adhesive residues, paint splashes, and rust film. Do not use high-pressure cleaners, steel brushes, or steel wool, as they can cause extraneous rust. Use only solvent-free cleaners. Ensure the luminaire housing is completely clean and dry. Stainless steel cleaners should be used according to their instructions. Cleaning agents must be free of hydrochloric acid and chlorides. Regular cleaning is recommended.
