E94AZRP0294 E70ACPSx0304x
E94AZRP0824 E70ACPSx0604x
The RFI filters are designed for the following conditions:
ƒ 6 interconnected devices,
ƒ each with a 50 m motor cable,
Mains filters DC power supply module
E94AZMP0294 E70ACPSx0304x
E94AZMP0824 E70ACPSx0604x
The mains filters are designed for the following conditions:
ƒ 10 interconnected devices,
ƒ each with a 50 m motor cable,
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".
Constellations with unfavourable or intensifying parasitic couplings
Compliance with EMC category C2 may also be interfered with by other circumstances:
ƒ Distribution of the axis modules over several control cabinets without efficient HF
equipotential bonding between the mounting plates
ƒ No use of Lenze system cables or cables with the same specifications
ƒ Poor connection of motor cable shields
ƒ Motor cable interruptions
ƒ Other interference sources (e.g. switched−mode power supplies)
ƒ Isochronous switching of the inverter output stages
