3 Operating Data
3.1 Electrical Operating Data
3.2 Electrical Features
3.3 Aerodynamics
Measurement
conditions:
Measured with a double chamber intake rig.
Normal air density = 1,2 kg/m3; Temperature 23°C +/- 3°C;
In the intake and outlet area should not be any solid obstruction within 0,5 m. Motor shaft
horizontal.
The information is only valid under the specified test conditions and may be changed by the
installation conditions. If there are deviations from the standard test conditions, the
characteristic values must be checked under the installed conditions.
3.4 Sound Data
Measurement
conditions:
Sound pressure level: 1 meter distance between microphone and the air intake.
Measured in a semianchoic chamber with a background noise level of Lp(A) < 5 dB(A)
For further measurement conditions see chapter aerodynamics.
