Recommended power supply units and tables for calculating the current consumption for the
assembly with SINAMICS S120 modules can be found in the "Cabinet Construction and
EMC Booksize" chapter in the
Note
A primary-side voltage dip for 20 ms must not cause the voltage on the secondary side
(24 V) to fall below the minimum permissible input voltage for the control unit.
