Electromagnetic compatibility (EMC) of the system
Category C1
In the following conditions, the Power Modules comply with the limit values of category C1:
● An external line filter provided for the Power Modules PM240-2 FSA, FSB, FSC 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 stated in the Technical Data
Power Modules that comply with the limit values of Category C1 are intended for use in the
first environment.
In the following conditions, the Power Modules comply with the limit values of category C2:
● An internal 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 stated in the Technical Data
Power Modules with an additional line reactor with a line impedance U
k
≥ 4 % or a low
harmonic filter (LHF) meet the requirements for the first environment. Without these
measures, Power Modules of Category C2 can only be operated in the second environment.
Power Modules with an integrated line filter comply with the limit values for category C3. The
Power Modules of the Blocksize series are all available in variants with an integrated line
filter.
The Power Modules of Category C3 and can only be used in the second environment.
Unfiltered Power Modules meet Category C4 and can only be used in the second
environment.
