Safety information

NOTICE
If line filters are used that SIEMENS has not certified for use with SINAMICS S120, this can
result in harmonics being fed back into the line supply. These harmonics can
damage/disturb other equipment connected to this line supply.
It is not permissible to connect other loads after the line filter.
NOTICE
If the system fault level is too low, this can result in faults/disturbances at the SINAMICS
Line Module. It can also result in faults and damage to other equipment and devices that
are connected at the same point of the line supply as the Line Module.
Note
If, for Line Modules, a transformer is used, this does not replace the external line reactor.

Module
Basic Line Module
Smart Line Module
Active Line Module
If a TN line supply is required on the secondary side, for example when using a Wideband
Line Filter, a transformer with grounded neutral point must be used. However, the loop
resistance must be small enough to trigger the fuses as fast as required.
See the section entitled "Fuses".
Vector group
Suggestion: Dyn0 or Yyn0; this means either a delta or star circuit on the primary side and
star circuit on the secondary side where the neutral point is brought-out.
