11.4.2 Selection of the mains filter
IT systems
TN systems Based on the application, use an mains filter from the following table.
1)
With lower output at continuous operation, filters with lower rated currents can be used too. Filters with higher
rated currents are necessary in case of using the overload capacity of the mains inverters cyclically. If over-
current is only needed one-time and non-recurrently (once per hour, for a maximum of 60 s), then the filters
suggested for operation at the rated power are sufficient.
NOTE!
EMC limit values are not defined for transient emission in power systems without
grounded star point (IT system). A fault state (motor ground fault) can lead to the
damage of the mains filter.
It is not recommended to use mains filter in IT systems. The transient emission can
exceed the limit values of category C3.
