NOTICE
Damage to the line filter due to interchanging the input and output
The line filter can be damaged if the input and output connections are interchanged.
• Connect the incoming line supply cable to LINE L1, L2, L3.
• Connect the outgoing cable to line reactor at LOAD L1´, L2´, L3´.
NOTICE
Damage or fault to other loads when no line reactor is present
If the SINAMICS line filter is directly connected to the S120 Combi and not connected via
the associated line reactor, other loads can be damaged or destroyed.
• Connect the line filter to the S120 Combi via the associated line reactor.
• Connect additional loads upstream of the SINAMICS line filter (if required, vi
a a
s
eparate line filter).
NOTICE
Damage caused by third party filters
According to product standard IEC 61800-3, RFI suppression commensurate with the
relevant rated conditions is required. Line filters and line reactors are required for this
purpose.
The use of filters of other makes can lead to limit value violations, resonances,
overvoltages and irreparable damage to motors or other equipment.
• Only use line filters which are listed in this Manual.
• The machine manufacturer must provide verification that the machine equipped with th
e
dr
ive products and the installed suppression elements, e.g. line filters, is EMC-compliant
before the machines are placed in the market.
NOTICE
Damage caused by line filters which are not approved for the SINAMICS S120 Combi
The integrated infeed can be damaged or destroyed when using line filters that have not
been approved by SIEMENS for the SINAMICS S120 Combi Power Modules. Furthermore,
line harmonics can occur that damage or destroy loads connected to the same line supply.
It is not permissible to connect other loads after the line filter.
• Only use line filters which have been approved for the SINAMICS S120 Combi.
Note
System fault level at the infeed point
In order to comply with EMC limit values, Cate
gory C2 according to EN 61800-3, the system
fault level at the infeed point must be at least a factor 70 higher than the rated power of the
integrated infeed.
