Installation and Assembly
Balancing
Noise emission
The rotor is dynamically balanced.
For shaft ends with featherkeys, the balancing type is specified using the following
coding on the face of the shaft end:
•= Code "F" means balancing with a complete featherkey (standard version).
•= Code "H" signifies balancing with half a featherkey (this is a special version
which must be specifically ordered). this means, in order to maintain the
balancing quality, it is necessary to cut back the part of the featherkey that
protrudes out of the drive element and the shaft profile if the motor has a short
power take-off element.
Please make sure that the power take-off element is correctly balanced e.g. halfcoupling,
pulley, etc. Power take-off element may only be fitted or removed using
suitable equipment.
Warning
The featherkeys are only secured against falling out during transport. If the motor
has two shaft ends, and a power take-off element is only fitted to one end, steps
must be taken to prevent the featherkey at the other end from being slung out. If
the rotor has the type of balance "H", the featherkey must be cut back to roughly
half of its normal length.
Caution
Remove the rotor shipping brace, if fitted.
Pay attention to the information on the shaft end.
Power take-off elements may only be fitted or removed using suitable equipment.
When assessing the noise that is emitted at the workplace, it should be taken into
account that the A-weighted mean sound pressure level, measured in accordance
with DIN EN 21680-1, namely 70 dB(A), can be exceeded when the motor is
operated under load.
