Line reactors for Power Modules

2.1.1

Description

The line reactors limit low-frequency line harmonics and relieve the semiconductors in the
Power Modules. For this reason, line reactors must always be provided when Power
Modules are used.
2.1.2

Safety information

Caution
The 100 mm clearances above and to the side of the components must be observed.
Note
The connection lines to the Power Module must be kept as short as possible (max. 5 m).
Caution
Using line reactors not approved by SIEMENS for SINAMICS:
- Can damage/destroy Power Module.
- Line harmonics that may interfere with or damage other loads connected to the same line
supply.
Caution
The surface temperature of the line reactors may exceed 80 °C.
