Noise emissions
Noise emissions
During operation, the machine's noise emission levels can exceed those permitted at the
workplace, which can cause hearing damage.
• 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.
The following measures may help to reduce noise.
– Covers
– Noise insulation
– Hearing protection measures

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.
4.11
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 – or for some versions, on a supplementary plate.
Operate the machine in continuous operation in Zone A. Prolonged operation in Zone B is
not recommended:
• Exceeding the permissible tolerances for voltage and frequency can lead to an impermissibly
high temperature rise of the winding. This can result in long-term damage to the winding.
• Limit exceptions of this sort with regard to the values that arise, how often, and for how long
they occur.
• Where possible and within a reasonable time take corrective actions such as reducing the
power. In this way you can avoid that the service life of the machine is reduced as a result of
thermal aging.
