NOTICE
Damage to the system caused by line reactors that are not permissible
Line reactors that are not permissible can damage the Line Modules.
Line harmonics that damage/disturb other loads connected to the same line supply can also
occur.
• Only use line reactors or Active Interface Modules described in this manual.
Note
Malfunctions through magnetic fields
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 connection 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).
You must use shielded connection cables, whose cable shields are attached at both ends.
Shielding can only be omitted if the following conditions are met:
• The cables do not exceed 1 m in length.
• The cables are laid flush with the rear metal wall of the control cabinet.
• The cables are laid in a way that keeps them physically separate from signal cables.
Cables must be routed with a minimum clearance of 200 mm to the filter.
