Line reactors for Smart Line Modules
2.5.1
Description
Line reactors limit low-frequency line harmonics and reduce the load on the semiconductors
in the Smart Line Modules. For this reason, line reactors must always be provided when
Smart Line Modules are used.

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