■ 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.

2. An EMC plan for preventing disturbances is drawn up for the installation. A
template is available in Technical guide No. 3 EMC compliant installation and
configuration for a power drive system (3AFE61348280 [English]).
3. The motor and control cables are selected, and routed according to the electrical
planning guidelines of the drive. The EMC recommendations are obeyed.
4. The drive is installed according to its installation instructions. The EMC
recommendations are obeyed.
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.
