NOTICE
Damage to the main insulation
In systems where direct drives are connected to controlled infeeds, electrical oscillations
can occur with respect to ground potential. These oscillations are, among other things,
influenced by
• The lengths of the cables
• The size of the Active Line Module infeed unit
• The size of the motor
• The winding design of the motor
• The type of line supply
• The place of installation
The oscillations lead to increased voltage loads and may damage the main insulation!
• To dampen the oscillations we recommend using the associated Active Interface
Note
The corresponding Active Interface Module must be used when operated with an Active Line
Module controlled infeed unit.
