5.7.3. Noise filters
DVS drives are fitted with an EMI filter to limit radio frequency interference that could affect the mains.
Consult the Electro-Magnetic Compatibility Guide for further information on the subject of noise filters.
You can request a copy of the Electro-Magnetic Compatibility Guide from your nearest TDE office.
The Guide lists the power and control panel installation standards that must be followed to ensure EMC conformity according
to Directive 89/336/EEC. (These standards cover the installation, whenever necessary, of external filters and mains chokes,
cable shielding, ground connections, etc..)
The Guide also explains the background to EMC standards and lists the various conformity tests performed on TDE equipment.
