Second environment (drive of category C4)
If the provisions under Second environment (drive of category C3) cannot be met,
e.g. the drive cannot be equipped with EMC filter +E200 when installed to an IT
(ungrounded) 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.
“C-tick” marking
A “C-tick” mark is attached to each drive in order to verify compliance with the EMC
product standard (EN 61800-3:2004), required under the Trans-Tasman
Electromagnetic Compatibility Scheme for levels 1, 2 and 3 in Australia and New
Zealand. See section Compliance with EN 61800-3:2004.
Marine type approvals
The ACS800-01/U1 drives with option +C132 are marine-type-approved.
For more information, see ACS800-01/U1/04/U4 Marine Supplement
[3AFE68291275 (English)].
