In order to have safe and reliable LED driver operation, the LED luminaires will 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 drivers 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 datasheet. Specifications of the LED driver may never exceed the operating conditions as per the product datasheet. Wiring considerations Installation & operational considerations Wire type and cross section Maximum tc temperature Please refer to datasheets connections & mechanical data Reliable operation and lifetime is only guaranteed if the maximum tc point temperature is not exceeded under the conditions of use. Wiring insulation Strain Relief for independent use According to recommendations in EN 60598 Maximum wire lengths Some of the Helvar LED drivers allow use both inside the luminaire and outside the luminaire, via a strain relief. The strain Please refer to datasheets connections & mechanical data relief provides reliable fastening method for the mains and LED output wiring. Wire connections Ensure that the LED driver does not exceed temperature higher Please refer to datasheets connections diagram than specified on the product datasheets. Miniature Circuit Breakers (MCB) The general preferred installation position of LED drivers is to have the top cover facing upwards. Type-C MCBs with trip characteristics in according to EN 60898 are recommended. Current setting resistor The Helvar LL2x35 driver platforms feature an adjustable constant LED driver earthing current output. LED drivers are designed to support different luminaire An external resistor can be inserted in to the current setting classifications, like Class I or Class II fittings (no earth required). terminal, allowing the user to adjust the LED driver output Please check the individual LED driver type for its exact safety current. class rating. When no external resistor is connected, then the LED drivers will For Helvar LED drivers to have a reliable operation and EMC operate at their default lowest current level. performance, the luminaires are expected to have an earth connection. A standard through-hole resistor can be used for the current setting. To achieve the most accurate output current it is When using a SELV-rated LED driver, then the SELV driver output recommended to select a quality low tolerance resistor. has to be insulated from the luminaire earth connection (ref. EN60598-1 luminaire standard). For the resistor / current value selection, please refer to the enclosed table below.
