SIMODRIVE 611 Configuration Manual (PJU) – 02/2012 Edition
When the requirements regarding system fault level are observed and when
using the appropriate line supply filters, the harmonics fed back into the line
supply lie below the compatibility level of Class 3 of the electromagnetic envi-
ronment of industrial plants and systems according to EN61000–2–4:2002.
When the recommended SIEMENS line filter is used and the EMC mounting/
installation regulations are complied with, the noise emission limits according to
EN50081–2 Electromagnetic Compatibility (EMC) – Generic Standard, Noise
Immunity/emission – Part 2: Industrial environments (1993) are complied with.
Notice
If line filters are used that SIEMENS has not certified for use with SIMODRIVE
6SN11xx/6SLxx, this can result in harmonics being fed back into the line
supply. These harmonics can damage/disturb other equipment connected to
this line supply. Certification, e.g. CE is invalid.
Certificates from Siemens are invalid, for example CE , UL. You are responsible
for generating/obtaining the certificates for this new combination.
It is not permissible to connect additional loads after the line filter

Line supply connection conditions for NE modules
Module
Description
The NE modules are designed for symmetrical 3–phase line supplies with grounded neutral point: TN systems. No further
consumers with asymmetric load (single–phase) may be connected for transformers with non–loadable neutral point.
The line supply specifications according to EN 50178 are complied with as a result of the series (upstream) line reactor (for
5 kW and 10 kW UI, these are integrated in the module).
Notice
The described minimum line supply fault level is needed to trigger the fuses in the case of ground fault and short–circuit within
the prescribed time in order to protect the plant and prevent damage and faults at other devices.
An insufficient system fault level (short–circuit power) increases the triggering and also prevents the triggering of the fuses.
This can cause, for example, arcs with the consequent fire of danger.
The following applies for several converters connected to one line supply:
The S
K
of the line supply must as a minimum, be sufficient for the highest rating converter connected to it. When selecting
and dimensioning the protective elements, Chapter 7.3 must be carefully observed!
The required apparent power of the line supply for each NE module is Sn = P
n
1.27. When operating one infeed alone on
a matching transformer, as a minimum, an S
K
of 0.73 times the value from the table is permissible.
