Second environment (drive of category C3)

The drive complies with the standard with the following provisions:
1. Frame sizes R2...R5: The drive is equipped with EMC filter +E200. The filter is suitable for TN
(earthed) systems only.
Frame size R6: The drive is equipped with EMC filter +E210. The filter is 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
be equipped with EMC filter +E200 when installed to an IT (unearthed) network, 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 inherent 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
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.

Machinery Directive

The drive complies with the European Union Machinery Directive (98/37/EC) requirements for an
equipment intended to be incorporated into machinery.
