ABB ACS880 - Category C4

￭ Category C4
The drive complies with the C4 category with these provisions:
1. It is ensured that no excessive emission is propagated to neighboring 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.
