Line-side power components protect the connected components against transient or continuous overvoltages and ensure that specified limit values are maintained.

To limit the emitted interference, the converters are equipped as standard with a radio interference suppression filter that conforms to the limits defined in Category C3. SINAMICS G130 converters equipped with a line filter also meet the limits for use in the first environment (Category C2) according to EN 61800‑3 ¹⁾.

SINAMICS G130 converters comply with the noise immunity requirements defined in this standard for the first and second environments.

In conjunction with line reactors, line filters limit the conducted interference emitted by the Power Modules to the limit values of Category C2 defined in product standard EN 61800‑3. Provided that the system has been set up in accordance with the EMC installation guidelines, the limit values at the installation location will be in accordance with the requirements for environment 1.

The line filters are suitable for grounded systems (TN or TT systems with grounded neutral point).
