EMC test results

Emission

Subsequent test results have been obtained using a
system with a VLT frequency converter (with RFI filter
module) a screened control cable and control box
with potentiometer, unscreened motor cable and mo-
tor.
Standard
EN 55011
gr.1 Class A 150 KHz - 30 MHz
EN 55011 Enclosure
gr.1 Class A 30 MHz - 1 GHz
1 Using RFI and motor filter for unscreened motor cable. Max.100 m, see page 88.
2 RFI and motor filter not available for VLT 2040-2050, 3 x 208-240 V
3 VLT 2040-2050, 3 x 208-240 V are not available with built-in RFI filter.
4 VLT 2000 up to 415 V versions are available with built-in RFI filter.
With the purpose of minimising the cable-conducted
interference to the mains supply and the radiated
interference from the frequency converter system, the
motor cables should be kept as short as possible.
According to experience, most installations represent
only a slight risk of any interference from radiation.
