Material damage can occur if the supply voltage is too high for the
insulation system.
The machines can be operated with line voltages ≤ 500 V with
SINAMICS G converters and SINAMICS S converters (uncontrolled and
controlled infeed) when maintaining the permissible peak voltages.
The maximum permissible voltage rate of rise (gradient) is 9 kV/µs.

For VSD machines, the following data apply:
Û
conductor-conductor
≤ 1600 V, Û
conductor-ground
