NOTE
1
Over All (dB):
(B, G, N is already rectified)
2
Operating conditons:
•
Power source: Y1: 380-415V 50Hz
3
Measuring place: Anechoic chamber (conversion value)
4
The operation sound is measured in anechoic chamber, if it is measured under the
actual installation conditions, it is normally over the set value due to enviromental
noise and reflection

1
Sound power level is an absolute value that a sound source generates.
2
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details, please refer to sound level
drawings.
3
Mentioned values are theoretical values based on sound results of individual installed units.
Possible deviations for sound values due to variety of installation patterns are not taken into account.
