Second environment (drive of category C3)
The drive complies with the standard with the following provisions:
1. The drive is equipped with EMC filter E200 [suitable for TN (earthed) systems] or E210 [suitable for
TN (earthed) and IT (unearthed) systems].
2. The motor and control cables are selected as specified in the
Hardware Manual
.
3. The drive is installed according to the instructions given in the
Hardware Manual
.
4. Maximum cable length is 100 metres.
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.
Second environment (drive of category C4)
If the provisions under
Second environment (drive of 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 is strongly
recommended.
2. An EMC plan for preventing disturbances is drawn up for the installation. A template is available
from the local ABB representative.
3. The drive is installed according to the instructions given in the
Hardware Manual
.
4. The motor and control cables used are selected as specified 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.
