Installation

Must be installed by a qualified electrician in line with the current edition of BS 7671 (IET Wiring Regulations). Mean Well’s data sheet notes that this model does not meet the EN 61000-3-2 harmonic limits for lighting equipment, so for lighting on 230V public mains your electrician may specify a power-factor-corrected LED driver instead.
