Siemens SINAMICS G115D Operating Instructions Manual page 385

Second environment - category C2
Conducted and radiated interference emissions
The converters meet the limit values of IEC 61800-3 Category C2 with regard to conducted
and radiated interference emissions under the following conditions:
• EMC compliant installation and configuration by qualified technician
• Operation on TN or TT line supply with grounded neutral point
• Permissible motor cable length
• Shielded motor cable with low capacitance
• Shielded external braking resistor cable with low capacitance
• Pulse frequency ≤ factory setting
• Converters with integrated C2 line filter
Note
The SINAMICS G115D converter is designed for operation in the second environment
(industrial area) and may not be used in the first environment (residential area) unless the
appropriate noise suppression measures have been adopted.
Note
A power drive system consisting of multiple units connected together in daisy-chain may
require further measures to meet EMC requirements.
