Electromagnetic Compatibility (Emc) - Siemens S120 PM240-2 Manual

4 ELECTROMAGNETIC COMPATIBILITY (EMC)

Together with a system configuration in conformity with EMC standards, the line filters limit the conducted
interference emitted by the Power Modules to limit values according to standard EN61800-3, which defines
the installation Ambient and the Category of Drive Systems from C1 (best) to C4 (worst).
All POWER MODULES (PM) delivered are provided with line filter, and they are in conformity with category
C3 (industrial) in accordance with the standard EN 61800-3.
For PM Block Size this is obtained by mains integrals filters,
The PM with a suitable line filter shall correspond to the category C2 for domestic installations, provided that:
- they are installed and put into service by a specialist (according to the definition given by the
normative), in compliance with the limit values for electromagnetic compatibility
- the below shown additional requisites are respected:

Connection by use of a shielded cable at reduced capacity

Motor cable shorter than 25 m in PM Blocksize

Pulse frequency ≤ 4 kHz in the PM Blocksize

Current ≤ nominal input current in the technical data
