Category C4
If the provisions under Category C3 cannot be met, the requirements of the standard can
be met as follows:
1. It is ensured that no excessive emission is propagated to neighbouring low-voltage
networks. In some cases, the natural 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.
2. An EMC plan for preventing disturbances is drawn up for the installation. A template is
available from the local ABB representative.
3. The motor and control cables are selected as specified in the hardware manual.
4. The drive is installed according to the instructions given in the hardware manual.
WARNING! A drive of category C4 is not intended to be used on a low-voltage public
network which supplies domestic premises. Radio frequency interference is expected if
the drive is used on such a network.
EAC (Eurasian Conformity) marking
The drive has EAC certification. EAC marking is required in Russia, Belarus and
Kazakhstan.
EIP (Electronic Information Products) marking
An EIP mark is attached to the drive to verify that the drive complies with the
regulations of the Chinese Administrative Measure on the Control of Pollution Caused by
Electronic Information Products.
