4 EMC-COMPLIANT INSTALLATION (EMC)
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.
For PM 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:
1. they are installed and put into service by a specialist (according to the definition given by the norma-
tive), 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
Pulse frequency ≤ 4 kHz
Current ≤ nominal input current in the technical data
The shield connection kit allows easy and efficient connection of the necessary shield to achieve EMC-
compliant installation of the inverter. If no shield connection kit is used, you can alternatively mount the de-
vice and additional components on a metal mounting plate with excellent electrical conductivity and a large
contact area. This mounting plate must be connected to the cabinet panel and the PE or EMC bus bar.
The following diagram shows an example of EMC-compliant installation of the inverter frame size C.
Shielding method
The following illustration shows an example with and without the shielding plate.
