Description

Line reactors for Smart Line Modules limit low-frequency line harmonics to permissible
values. For this reason, line reactors should always be used.

Safety information

Caution
A clearance of 100 mm must be maintained around the reactor in order to minimize the
influence of magnetic fields in other components and cables.
Note
The connection cables to the Line Module must be as short as possible (max. 10 m).
If possible, they should be shielded.
Unless it can otherwise be avoided, cables must be routed past the line reactor at a
minimum distance of 150 mm.
Caution
Only the line reactors described in this Equipment Manual must be used.
When using line reactors that have not been released by SIEMENS for SINAMICS S120, the
following can occur:
- can damage/destroy Line Modules.
- cause line reactions that can damage or destroy other loads powered from the same
network.
Caution
The surface temperature of the line reactors may exceed 80 °C.
