Selection and Installation
Check the supply voltage at the installation against the 190–264Vac input range. Confirm the LED modules accept the specified DC output, and compare mounting points, wiring terminals and load requirements with the existing unit. Allow for temperature derating above +50°C. The manufacturer PDF lists a 32A derated output without auxiliary heat dissipation and requires an aluminium substrate in its environmental notes; follow the specified thermal mounting requirements.
