Siemens SINAMICS S120 Device Manual page 31

Active Line Modules are always used in conjunction with an Active Interface Module. Active
Interface Modules include the required pre-charging input circuit for the Active Line Module,
in addition to a Clean Power Filter.
These two components are considered to be an integral unit for SINAMICS S120 Cabinet
Modules NEMA and are supplied together.
For a compact configuration, Line Connection Modules with input currents of up to 3000 A
are available. Two Active Line Modules with their associated Active Interface Modules can
be operated in parallel on these Line Connection Modules.
