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

Category C3
Drive systems with a rated voltage < 1000 V, which are intended for use in the second
environment and not for use in the first environment.
Drive systems which correspond to category C3 may only be installed in the second
environment.
Category C4
Drive systems with a rated voltage ≥ 1000 V with an output current ≥ 400 A or for use in
complex systems in the second environment
Drive systems which correspond to category C4 may only be installed in the second
environment.
Note
Expert
An expert is a person or organization with the necessary experience for installing and/or
commissioning drive systems (Power Drive Systems - PDS), including the associated EMC
aspects.

Electromagnetic compatibility (EMC) of the system

Category C4
Unfiltered Power Modules meet Category C4 and can only be used in the second
environment.
Category C3
Power Modules with an integrated or similar external line filter meet the limit values for
Category C3.
Many of the Blocksize Power Modules are also available as variants with integrated line
filters. One exception is the PM340 Power Module frame size FSA for line voltage 3-phase
380 VAC to 480 VAC. An external line filter must be used for this Power Module.
External line filters are available for Chassis Power Modules.
The Power Modules of Category C3 and can only be used in the second environment.
Category C2
To ensure that the Power Modules with the appropriate line filter meet the limit values of
Category C2, the following conditions must be met:
● A shielded motor cable with low capacitance is used.
● The motor cable is
