4.12 Line reactors for Basic Line Modules
4.12.1

Description

Line reactors for Basic Line Modules limit low-frequency line harmonics to permissible
values. For this reason, line reactors should always be used.
4.12.2

Safety information

CAUTION
A clearance of 100 mm must be maintained around the reactor 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 Manual must be used.
The following can occur if line reactors are used that have not been approved for
SINAMICS S120 by SIEMENS:
- The Line Modules may become damaged/faulty.
- Line reactions can occur that can damage or interfere with other loads powered from the
same network.
The surface temperature of the line reactors may exceed 80 °C.
