Line reactors for Basic Line Modules
2.3.1
Description
Line reactors limit low-frequency line harmonics and reduce the load on the semiconductors
in the Basic Line Modules. A line reactor must be used in connection with a line filter or if
several Basic Line Modules are operated in parallel.
If a Basic Line Module is operated singly and no line filter is used, and with an effective line
impedance uk > 3 %, the line reactor is not necessary.

Safety information
CAUTION
The 100 mm cooling clearances above and to the side of the components must be
observed.
Note
The connecting cables to the Line Module must be kept as short as possible (max. 5 m).
CAUTION
When using line reactors that have not been approved by SIEMENS for SINAMICS, the
following can occur:
• The Basic Line Modules may become damaged/faulty.
• Line harmonics may interfere with or damage other loads connected to the same line
The surface temperature of the line reactors can exceed 80 °C.
