Installation Guide | SISO LCL and LC Filters
Loose or improperly mounted connections can damage the performance of the filter.
Make sure that all connections are tightened according to the instructions.
l
Cabling between inductors and capacitor banks must not be longer than 2 m.
l
Before connecting cables to the terminals, make sure that the surfaces of the terminals are properly cleaned.
l
If 2 cables/phase are used, it is recommended to connect cables to both sides of the terminals.
l
When routing the cables, avoid abrasion against sharp edges in inductor terminals and the frame of the enclosure.
