18.3 EMC: LMV5... system – VSD
The functional and EMC tests of the LMV5... system were conducted and successfully
completed with the following types of VSD:
Siemens: - SED2-1.5 / 35 B
Danfoss: - VT2807
In operation, VSDs produce electromagnetic interference. For this reason - to ensure
EMC of the entire system - the instructions provided by the manufacturers must be ob-
served:
Siemens: - Operating Instructions
→ EMC-compatible installation
Danfoss: - Technical Brochure → Radio Interference
Suppression Filters
- Data Sheet of Danfoss EMC filter for long
motor cables
When using other types of VSD, compliance with EMC regula-
tions and correct functioning are not ensured!
