resistors or of one of the converters can, for example, result in an impermissible increase in
the thyristor reverse voltages.
For this reason, the maximum input voltage depending on the device types (according to the
following table) must not be exceeded by any device:
If higher input voltages are present, SINAMICS DC MASTER Control Modules should be
used in connection with suitable external power units in order to achieve the required proof
voltage. The corresponding systems are available on request.
