Operation In The First Environment - Siemens SINAMICS G120 Hardware Installation Manual

● You use an inverter with integrated line filter.
Inverters with integrated filter comply with the requirements of the second environment,
Category C2 with reference to interference emission.
● If you use inverters without integrated filter, then you are responsible for verifying that the
interference emission is limited.
You can use a dedicated radio interference suppression filter for each inverter - or a
common filter for several inverters.
Interference emission - operation in the second environment, Category C4
When connected to IT line supplies, only filtered inverters are permissible. Use external filters
without capacitors with respect to ground to limit symmetrical interference emission. When
necessary, contact one of our Solution Partners

Operation in the first environment

Interference immunity
You do not have to take any additional measures regarding interference immunity.
Interference emission - operation in the first environment, Category C2
In order that you may operate the drive system in the first environment, Category C2, then in
addition to the requirements for use in the second environment, you must also observe the
limit values related to harmonic currents.
Note
Maintaining the limit values for harmonic currents
With respect to the compliance with limits for harmonic currents, the EMC product standard
EN61800‑3 for PDS refers to compliance with standards EN 61000‑3‑2 and EN 61000‑3‑12.
Inverters with an LO base load input current ≤ 16 A:
These devices are not subject to any limit values, and as a consequence can be connected
to the public low-voltage grid without any prior consultation.
