Line supply connection conditions for line supply infeed
For technical data, refer to Chapter 6.3 and Tables 6-6/7-1.
SIMODRIVE infeed units are designed to be connected to line supplies with
compatibility level, Class 3 of electromagnetic environments in industrial plants
and systems according to IEC/DIN EN61000–2–4:2002.
When the EMC mounting/installation guidelines are complied with, noise immu-
nity values according to IEC/DIN EN61000–6–2 Electromagnetic Compatibility
(EMC) – Generic Standard, Noise Immunity/emission – Part 2: Industrial envi-
ronments (1999) are complied with.
SIMODRIVE units with 16–kW I/R module and 5–, 10–, 28–, 36–kW UI module
may be directly connected to TN line supplies with delayed tripping, selective
universal current sensitive RCCBs (type B) under the following limitations.
1. It is only permissible to use a delayed–tripping (selective) AC/DC–sensitive
RCCB.
2. It is not possible to connect RCCBs in series in order to implement selective
tripping.
3. The maximum permissible ground resistance of the RCCB must be main-
tained (83 Ohm maximum for RCCBs with a nominal differential current I
0.3 A).
4. The total length of all of the shielded power cables used in the drive group
(motor feeder cables including line supply feeder cables from line filters to
NE connection terminals) must be less than 350 m.
5. Only the line filters intended for the purpose may be used for operation of
the equipment.
6. Note: The currently widely established AC or pulse–current sensitive
RCCBs are definitely not suitable!
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, 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.
It is not permissible to connect other loads after the line filter.
