Additional measures for EMC improvement
Depending on the application, the following measures can improve the EMC-dependent values:
NOTE: If using an additional input filter, it should be mounted as close as possible to the drive and
connected directly to the supply mains via an unshielded cable.
EMC measures Objective
Operate product on mains with grounded neutral point. Enables effectiveness of mains
filter.
Surge arrester if there is a risk of overvoltage. Reduces the risk of damage
caused by overvoltage.
EMC measures Objective
Use mains reactors Reduces mains harmonics,
prolongs product service life.
Use external mains filters Improves the EMC limit values.
Additional EMC measures, for example mounting in a closed control cabinet with
15 dB shielding attenuation of radiated interference
