Siemens SINAMICS G120C DP User Manual

Second environment - category C3
Immunity
The converters comply with the requirements of the standard.
Interference emission for un󹪝ltered converters
Converters with integrated 󹪝lter comply with the requirements of the standard.
Cable-conducted, high-frequency noise emission of an un󹪝ltered converter
Either install an external 󹪝lter for the converter - or install corresponding 󹪝lters at the system
level.
Further information is provided on the Internet:
Compliance with EMC limits with un󹪝ltered devices (https://
support.industry.siemens.com/cs/ww/en/view/109750634)
Field-conducted, high-frequency noise emission of an un󹪝ltered converter
When installed professionally in accordance with EMC guidelines, the converters ful󹪝ll the
requirements of the standard.
Second environment - category C2
Immunity
The converter is suitable for the "second environment".
Emitted interference
The converters ful󹪝ll the requirements of the standard when the following conditions are
satis󹪝ed.
• You are using a converter with an integrated 󹪝lter.
• The converter is connected to a TN or TT line supply with grounded neutral point.
• You use a shielded motor cable with low capacitance.
• You maintain the permissible motor cable length.
Maximum permissible motor cable length (Page80)
• Converter and motor have been installed in compliance with EMC, carefully taking into
consideration the installation notes.
• Condition for the converter pulse frequency:
– FSAA…FSC: Pulse frequency<4 kHz
– FSD…FSF: The pulse frequency is not higher than the value set in the factory.
First environment - category C2
To enable you to use the converter in the 󹪝rst environment, during installation you must observe
the limit values for the cable-conducted, low-frequency disturbance variables (harmonics)
in addition to the limit values for the "second environment - category C2".
