Technical data 331
Note:
It is not allowed to use the optional EMC filter in these conditions:
• on IT (ungrounded) systems, because the supply network gets connected to the
ground potential through EMC filter capacitors which may cause danger or
damage the drive.
• on a corner-grounded TN system as this would damage the drive.
Second environment (drive of category C3)
The drive complies with the standard with the following provisions:
1. The drive is equipped with optional mains filter JFI-xx.
2. The motor and control cables are selected as specified in chapter
.
3. The drive is installed according to the instructions given in this manual.
4. Motor cable length does not exceed 50 metres (164 ft).
Second environment (drive of category C4)
The drive complies with the standard with the following provisions:
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, 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 chapter
.
4. The drive is installed according to the instructions given in this manual.
