Preparations for use

4.11 Noise emissions

Danger if there is no support at the NDE
If the machine has no support at the NDE, the flange cannot hold the weight of the machine.
The machine or machine parts may loosen.
This can result in death, serious injury or material damage.
● Use an appropriately sized support base.

● Ensure that nobody is in the area of increased noise emissions during machine operation.
● Take steps to reduce noise so that the machine can be operated safely within your system.
4.12

Rotational speed limit values

Excessive rotational speed can lead to serious damage to the machine. This can result in
death, serious injury, or material damage.
● Avoid operation above the permissible speed by using the appropriate control function.
● Observe the speeds stamped on the rating plate.
4.13

Voltage and frequency fluctuations during line operation

Unless otherwise stated on the rating plate, the permissible voltage/frequency fluctuation is
corresponds to Zone B in IEC / EN 60034‑1. Permissible fluctuations that go beyond this are
indicated on the rating plate.
