Design

SINAMICS S120 Active Line Connection Modules are Active Infeeds for four-quadrant operation. They consist of a
Line Connection Module and a liquid-cooled Active Line Module including the associated liquid-cooled Active
Interface Module.
Note:
By contrast with air-cooled S120 Cabinet Modules for which Line Connection Modules and Active Line Modules incl.
Active Interface Modules are available as separate Cabinet Modules, the Line Connection Modules and Active Line
Modules including Active Interface Modules for liquid-cooled S120 Cabinet Modules are only available as an
optimally coordinated, "all-in-one" module combination, referred to as the "Active Line Connection Module".
Active Line Connection Modules with output ratings from 630 - 900 kW for 400 V or 1100 - 1700 kW for 690 V are
available for liquid-cooled SINAMICS S120 Cabinet Modules.
Example of an Active Line Connection Module with degree of protection IP55
(Line Connection Module (on the left) + Active Line Module (on the right) incl. Active Interface Module (in the center))
The Line Connection Module (shown on the left in the picture) includes the line-side connections, the fuse switch
disconnector and main contactor (≤ 800 A) or circuit breaker (> 800 A) and connects the Active Interface Module to
the supply system.
The Active Interface Module (shown in the center in the picture) contains the liquid-cooled, line-side Clean Power
Filter for the Active Line Module, the Voltage Sensing Module VSM and the precharging circuit (precharging contactor
with precharging resistors).
The Active Line Module (shown on the right in the picture) has an actively pulsed, regulated rectifier / regenerative
unit.
