ABB ACS180, Hardware Manual, Page: 125 / 168

￭
Category C2
This is applicable to ACS180-04S-...-1 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.
2. The drive is installed according to the instructions given in this manual.
3. The maximum motor cable length specification has not been exceeded.
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!
You can install a drive with the internal EMC filter connected only on a
symmetrically grounded TN-S system.

Category C3
This is applicable to ACS180-04S-...-4 drives with an internal EMC C3 filter.
The drive complies with the standard with the following provisions:
1. The motor and control cables are selected as specified in this manual.
2. The drive is installed according to the instructions given in this manual.
3. The maximum motor cable length specification has not been exceeded.
WARNING!
To prevent radio-frequency interference, do not use a category C3 drive on
a low-voltage public network which supplies domestic premises.
WARNING!
You can install a drive with the internal EMC filter connected only on a
symmetrically grounded TN-S system.

Category C4
This is applicable to ACS180-04N-...-1/4 and ACS180-04S-...-2 drives.
If the provisions in Category C2 or C3 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.
