Installation guidelines of EMC filter
Install the EMC filter as close as possible to the AMD2000 drive.
A shielded cable is recommended if the distance between mains filter and drive exceeds 30cm.
Minimize
cross talk of “clean” lines (mains supply to filter input) to “noisy” power cables by
careful routing and cable segregation.
Ensure filter is installed on an unpainted metal gear tray to provide a low impedance return
path. Otherwise connect filter to gear tray with minimal length flat copper braid strap
Connect the filter to PE for safety requirements, but note that PE cable does not provide a low
impedance return path for common mode currents due to cable length and skin effect of
conductors. Best EMC equipotential bonding is achieved using careful mounting or use of
braided earth straps.
Minimize motor cable length, and use correctly shielded motor cables. For longer cable lengths
a ferrite ring on the drive output will reduce EMC noise
Ensure that the EMC filter is used with a mains line inductor to reduce rms currents. Otherwise
the current rating of the EMC filter may be exceeded.
