Precondition: Plant manufacturers and operating companies agree on plant-specific measures in an
1)
appropriate EMC plan. If specified in the product documentation, the drive can also be operated on
ungrounded line supplies (IT line systems) in accordance with product standard IEC 61800‑3
More information
To comply with product standards of plants and/or machines, when integrating the drive in
plants or machines, additional measures may be required. The additional measures are the
responsibility of the plant builder or machine OEM.
Disturbance-free operation of the drive is only guaranteed when specialist personnel carry
out the installation work in strict compliance with EMC regulations.
4.13.4

Limit values for current harmonics in the industrial supply

Description
IEC 61800‑3 does not define any current harmonic limits when converters are operated on
industrial line supplies. A system evaluation according to IEC 61000‑3‑14 or
IEC 61800‑3 Annex B.4 is recommended.
More information
We recommend using the "TIA Selection Tool" configuring software to calculate the current
harmonics of the converter.
More information about the "TIA Selection Tool" is available on the Internet:
