Electromagnetic Compatibility (Emc) Of The System - Siemens SINAMICS S120 Equipment Manual

Mains connection and line-side power components
4.6 Line filter
NOTICE
Damage due to multiple loads being connected to the same line infeed point
Components can be damaged if several loads (consumers) are connected to the same line
infeed point.
• Suppress interference on the additional loads using appropriate line filters.
NOTICE
Line filter damage due to interchanged connections
Interchanging the input and output connections will damage the line filters.
• Connect the incoming line supply cable to LINE L1, L2, L3.
• Connect the outgoing cable to the Power Module at LOAD/LAST L1´, L2´, L3´ (U, V, W).
NOTICE
Damage to loads due to the incorrect line filter
Unsuitable line filters can cause line harmonics, which damage or destroy loads connected
to the same line supply.
• Only use line filters released by Siemens for SINAMICS.

Electromagnetic compatibility (EMC) of the system

An explanation of the EMC environment and EMC Categories is provided in Chapter
"Environments and categories (Page 368)".
Category C1
Under the following conditions, the Power Modules comply with the limit values of Category
C1:
● A Power Module blocksize PM240-2 FSA, FSB, FSC with external line filter is used.
● A shielded motor cable with low capacitance is used.
● The motor cable is shorter than 50 m. The pulse frequency is less than or equal to the
rated pulse frequency.
● The current is less than or equal to the rated input current listed in the Technical data
Power Modules that comply with the limit values of category C1 are intended for use in the
first environment. For more details, see Chapter "Interference emissions and interference
immunity (Page 370)".
