1. The motor and control cables are selected as specified in this manual. The EMC
recommendations are obeyed.
2. The maximum motor cable length does not exceed the specified maximum.
See EMC compatibility and motor cable length (page 168)
3. The drive is installed according to the instructions (IEC) given in this manual.
This product can cause radio-frequency inference. In a residential or domestic
environment, supplementary mitigation measures may be required in addition to
the requirements listed above for the CE compliance.
WARNING!
Do not install a drive with the internal EMC filter connected to a grounding
system that the EMC filter is not compatible with (for example, an IT system).
The supply network becomes connected to ground potential through the
internal EMC filter capacitors, which can cause danger or damage to the
drive.
WARNING!
To prevent radio-frequency interference, do not use a category C2 drive on
a low-voltage public network that supplies domestic premises.
￭
Category C3
The drive has an internal EMC C2 filter as standard. No EMC C3 filter for category
C3 is available.
￭
Category C4
If the provisions in category 2 or 3 are not met, the requirements of the standard
can be met as follows:
1. It is ensured that no excessive emission is propagated to neighboring
low-voltage networks. In some cases, the inherent suppression in transformers
and cables is sufficient. If in doubt, the supply transformer with static screening
between the primary and secondary windings can be used.
