Line reactors for Power Modules

2.1.1

Description

The line reactors limit low-frequency line harmonics and reduce the load on the
semiconductors in the Power Modules. A line reactor is not required where 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 Power 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 Power Modules could be damaged/destroyed.
• 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.
