6.6 Connecting the converter
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 G converters and SINAMICS S
converters (uncontrolled and controlled infeed) when maintaining the permissible peak
voltages.
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).
