NOTICE
Material damage caused by an excessively high supply voltage
Material damage can occur if the supply voltage is too high for the insulation system.
• Observe the values in the following tables.
SIMOTICS machines can be operated with SINAMICS converters (uncontrolled and controlled
infeed) when maintaining the permissible voltage peaks.
The insulation system of SIMOTICS machines corresponds to the specifications laid down in
IEC 60034-18-41 according to voltage stress category C (IVIC C = high stress).
