Using the Active Line Modules Chassis-2 in line supplies in conformance with the standard
EN 61000-2-4, Class 2
When using Active Line Modules Chassis-2 in line supplies in conformance with Standard
EN 61000-2-4, Class 2, the following conditions must be carefully observed:
• With the factory preset step-up factor (= 1.5) and an R
4 kHz, the Class 2 of the EN 61000-2-4 is adhered to.
• For a step-up factor ≥1.5, the pulse frequency of Active Line Modules Chassis-2 must be
set to 8 kHz.
When used in the TN system and during operation of the Active Line Module Chassis 2 or
the connected Motor Module with increased pulse frequency, you will receive the
permitted cable lengths upon request.
Note
In complying with the limit values according to standard EN 61000-2-4, Class 2 and Class 3,
the evaluation of the conductor-conductor voltage in a frequency range of <9 kHz is
assumed.
Use of the Active Line Modules Chassis-2 in weak grids
When the Active Line Modules Chassis-2 are used in weak grids (R
must be activated (parameter p5200.0 = 1) to suppress increased line harmonic distortions.
Note
Activation of the band-stop filter
The "Additional control" function module must be activated to enable the band-stop filter. For
additional information, see "SINAMICS S120 Function Manual Drive Functions".
After the band-stop filter is activated, no further settings are necessary. It can be operated
using the factory parameterization.
When using an Active Line Modules Chassis-2 on strong grids (R
should not be activated (parameter p5200.0 = 0) to avoid unfavorable overshoots. For more
information, see Configuration Manual Low Voltage.
