Environmental requirements

Noise levels

Smaller machines have a sound pressure level that not 

exceeding 70 dB(A).
The following table shows catalogue values of sound 

pressure levels at 1 m from the machine surface.

Values for specific machines can be found in the relevant 

product catalogues. Tolerance acc ± 3 dB(A).
The table values refer to 50 Hz sinusoidal supply

conditions.

For 60 Hz sinusoidal supply, add 4 dB(A) to the above

values.
For sound pressure levels with non-sinusoidal supplies,

contact ABB Sales Office.
Sound pressure levels for all machines in the above 

frame sizes having separate cooling systems and for

series M2F*/M3F*, M2L*/M3L*, and M2R*/M3R*, are

indicated in separate specific Machine Instructions.

Rewinding

Rewinding should always be carried out by qualified 

repair shops.
Smoke venting and other special motors should not be

rewound without first contacting ABB Motors.
