Installation and conformity -freeddm in Conformity & standards General and safety requirements LC1x25-CC LED driver is suited for built-in Luminaire usage. In order to have safe and reliable LED driver operation, the LED luminaires wilt need to comply with the relevant standards and regulations (e.g. IEC/EN 60598-1). The LED luminaire shall be designed to adequately protect the LED driver from dust, moisture and pollution. The luminaire manufacturer is responsible for the correct choice and installation of the LED drivers according to the application and product datasheets. Operating...
