The RFI filters are designed for the following conditions:
ƒ
6 interconnected devices,
ƒ
each with a 10 m motor cable,
ƒ
EMC category C2.
In applications with a different number of interconnected devices or different motor cable
lengths, the filters may have to be specially dimensioned.
Note!
To observe EMC category C2, measures must be carried out on the
device-internal EMC filters of the drive components in the network system.
The measures for the individual devices are described in the chapter ”Wiring”,
section ”Earthing of internal EMC filters”.
When using the mains filters assigned, conditions must be observed for compliance with
EMC class C2:
ƒ
The measures for the use on IT systems must be applied to all axis modules in the
interconnection (separation of internal filter components from PE).
ƒ
The maximum sum total of all motor cable lengths (Σ l
mot
) for the filter used must
be observed.
