WARNING!
A drive of category C3 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.
￭
Category C4
The drive complies with the C4 category with these provisions:
1. It is made sure 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, a supply transformer with static screening
between the primary and secondary windings can be used.
