Electromagnetic Compatibility - Siemens S120 Instructions Manual

4 ELECTROMAGNETIC COMPATIBILITY

Together with a system configuration in conformity with EMC standards (see norms EN 61000-6-2,
EN61000-6-4, EN60204-1), 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 (<180A), this is obtained by mains integrals filters, while for the PM chassis must be
coupled to a line filter.
The PM with a suitable line filter shall correspond to the category C2 for domestic installations, provided that:
1. 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
2. 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 (100m in PM Chassis)

Pulse frequency ≤ 4 kHz in the PM Blocksize (≤ 2 kHz in the AM Chassis)

Current ≤ nominal input current in the technical data
WARNING
For the PM chassis is required an additional impedance coil to reach the C2 class
