6.6 Line reactors
Description
Line reactors are interfaces on the line side for the Smart Line Modules. They limit line harmonics
to permissible values. For this reason, line reactors must always be used when operating the Line
Modules.

Safety information

Burns resulting from high surface temperature of the line reactor
The line reactors can become very hot. You can get seriously burnt when touching the surface.
• Mount the line reactors so that contact is not possible. If this is not possible, attach clearly
• To prevent adjacent components from suffering damage due to these high temperatures,
Note
Malfunctions through magnetic fields
Line reactors produce magnetic fields that can disturb or damage components and cables.
• Arrange the components and cables at a suitable distance (at least 200 mm) or shield the
magnetic fields appropriately.
Note
Length of connecting cables
The connecting cables between line reactor and Line Module, as well as between line reactor
and line filter, must be kept as short as possible (max. 10 m).
Use shielded connecting cables and connect the cable shields at both ends.
Shielding is not required if the following preconditions are satisfied:
• The cables do not exceed 1 m in length.
• The cables are laid flush with the rear metal panel of the control cabinet.
• The cables are laid in a way that keeps them physically separate from signal cables.
All signal cables must be laid separately from the line reactor and from unshielded connecting
cables of the reactor with a minimum clearance of 200 mm.

CAUTION
visible and understandable warning notices at hazardous positions.
maintain a ventilation clearance of 100 mm on all sides of the line reactors.
