Notes
(1) EW 40°C; LW 45°C; Dt 5°C; ambient conditions: 7°CDB/6°CWB
(2) For water Dt 5°C
(3) Sound level is valid in free field condition because it is measured in a semi-anechoic room. Measured value under actual installation conditions will be higher due to environmental
noise and sound reflections.
(4) Values are sound pressure values measured at all sides (front, back, left, right, top) at 1m distance. The values do not occur simultaneously on all mentioned sides.
(5) Sound levels are measured at: EW 55°C; LW 65°C
(6) Sound levels are measured at: EW 70°C; LW 80°C
(7) In accordance with EN/IEC 61000-3-11, it may be necessary to consult the distribution network operator to ensure that the equipment is connected only to a supply with Zsys
(system impedance) ≤ Zmax
(8) EN/IEC 61000-3-11: European/international technical standard setting the limits for voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for
equipment with rated ≤ 75A
(9) EN/IEC 61000-3-12: European/international technical standard setting the limits for harmonic currents produced by equipment connected to public low-voltage system with input
