2.2 Line reactors for Basic Line Modules
2.2.1

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 if several Basic Line Modules are operated in parallel.
A line reactor is not required if a single Basic Line Module is used and the effective supply
impedance equals uk > 3 %.

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.
