* The optional I/O Extension Module provides additional DIs and DOs which share the same technical specifications as
those on the SINAMICS V20 converter.
The input and output terminals, numbered 1 to 16, are safety extra low voltage (SELV)
terminals and must only be connected to low voltage supplies.
