Line-side power components
3.1 Line reactors for Power Modules
NOTICE
Damage to the system caused by the use of inappropriate and not approved line reactors
Inappropriate and not approved line reactors can damage the Power Modules.
Line harmonics that damage/disturb other loads connected to the same line supply can also
occur.
• Only use line reactors that are listed 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 lines between line reactor and Power Module must be kept as short as
possible (max. 5 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.
Do not route any cables near the line reactor. If this cannot be avoided, observe a minimum
clearance of 200 mm.
