Wideband Line Filter for Active Line Modules
2.4
2.4.1
Description
The damping characteristics of Wideband Line Filters for Active Line Modules not only
conform with the requirements of EMC standards for the frequency range of 150 kHz to
30 MHz but also include low frequencies as of 2 kHz. As a result, these line filters have an
extended function area, which means that they can, to a certain extent, be used regardless
of the machine installation location and any unknown line properties (e.g. line impedance).
With these line filters, the limit values in accordance with Class A1 acc. to EN 55011 or
Category C2 acc. to EN 61800-3 for equipment, Group 1, are complied with.
The total cable length must be less than 350 m (motor cables, power supply cable between
line filter and Line Module).
2.4.2
Safety information
Caution
Line filters are only suitable for direct connection to TN systems.
Danger
The 100 mm clearances above and below the components must be observed. The mounting
position must ensure that cool air flows vertically through the filter. This measure prevents
thermal overloading of the filter.
Caution
The terminals must be correctly connected:
Incoming line cable to LINE/NETZ L1, L2, L3.
Outgoing cable to the line reactor to LOAD/LAST U, V, W.
Non-observance may damage the line filter.
Notice
The associated line module may only be connected to the SINAMICS line filter via the
associated line reactor. Additional loads must be connected in front of the SINAMICS line
filter (if required, via a separate line filter). If this is not observed, other loads could be
damaged or disturbed.
