Risk of explosion due to excessive temperature rise
If the end of the conductor is not correctly enclosed by the end sleeve,
but is trapped by it, this can lead to overheating. The temperature class
of the machine can be exceeded. This can trigger ignition of an explosive
mixture. This can result in death, serious injury or material damage.
• Insert only one conductor end into each end sleeve. Attach the end

sleeve correctly.
NOTICE
Excessively high supply voltage
Material damage can occur if the supply voltage is too high for
the insulation system.
SIMOTICS machines can be operated with SINAMICS G converters
and SINAMICS S converters (uncontrolled and controlled infeed)
when maintaining the permissible peak voltages.
Carefully observe the values in the following tables.
Rise times tr > 0.1 μ s.
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).
