Tables
1 Maximum A-weighted sound power level LWA in dB, at
no-load (excluding motors according to table 2) (Method
of cooling, IC code, see IEC 60034-6) (Degree of
protection, IP code, see IEC 60034-5)
2 Maximum A-weighted sound power level, LWA in dB at no-load
(for single-speed three-phase cage induction motors
IC01, IC11, IC21, IC411, IC511 and IC611)
3 Incremental expected increase, over no-load condition, in
A-weighted sound power levels in dB, (for rated load
condition for motors according to table 2)
