Category C2
This is applicable to drives with an internal EMC C2 filter.
The drive complies with the standard with the following provisions:
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 132) .

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.
