Noise emission
Prevention of hearing damage
If the permissible sound pressure level is exceeded, hearing damage can occur when
operating three-phase motors at their rated power.
The permissible sound pressure level is 70 dB (A).

Converter operation
4.7.1
Parameterizing the converter
• If the design of the motor requires connection to a particular converter type, the rating plate
will contain corresponding additional information.
• Correctly parameterize the converter. Parameterizing data can be taken from the machine
rating plates.
You can also find parameter data here:
– Operating instructions for the converter.
– SINAMICS Configuration Manuals.
• Do not exceed the specified limit rotational speed n
plate n
• Check that the machine is cooled sufficiently for commissioning purposes.
4.7.2
Converter input voltage
The insulation system of SIMOTICS LV machines always complies with the requirements of stress
category C (IVIC C = high stress). If voltage peaks higher than those specified according to IVIC C
can occur, contact the Service Center (Page 12).
• For a line supply voltage (converter input voltage) up to max. 480 V, and when controlled
from a SINAMICS converter with uncontrolled/controlled infeed: Comply with the guidelines
for configuring motor and converter.
• For line voltages (converter input voltages) higher than 480 V, motors have an appropriate
insulation system when ordered for converter operation.
• Operation with a converter from another manufacturer: Comply with the permissible voltage
peaks according to IEC 60034-18-41 in accordance with stress category C, dependent on the
particular line voltage (converter input voltage) and the motor insulation system.
