ACS/ACC 6x7 (75 to 3000 kW) Frequency Converters
A CE mark is attached to ACS/ACC 607/617/627/677 drives to verify that the unit
follows the provisions of the European Low Voltage and EMC Directives (Directive 73/
23/EEC, as amended by 93/68/EEC and Directive 89/336/EEC, as amended by 93/68/
EEC).
EMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronic
equipment to operate without problems within an electromagnetic environment.
Likewise, the equipment must not disturb or interfere with any other product or system
within its locality.
The EMC Directive defines the requirements for immunity and emissions of electrical
equipment used within the European Union. The EMC product standard [EN 61800-3 +
Amendment A11 (2000)] covers requirements stated for drives.
First environment includes establishments connected to a low-voltage network which
supplies buildings used for domestic purposes.
Second environment includes establishments connected to a network not supplying
domestic premises.
Restricted distribution: mode of sales distribution in which the manufacturer restricts
the supply of equipment to suppliers, customers or users who separately or jointly have
technical competence in the EMC requirements of the application of drives.
Unrestricted distribution: mode of sales distribution in which the supply of equipment is
not dependent on the EMC competence of the customer or user for the application of
drives.
The drive complies with the EMC Directive in industrial low-voltage network, and IT
networks (unearthed mains) with the following provisions.
1. The drive is of type ACS/ACC 607 equipped with EMC filtering (refer to Table A-1).
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! The drive may cause radio interference if used in a residential or domestic
environment. The user is required to take measures to prevent interference, in addition
to the requirements for CE compliance listed above, if necessary.
1. The drive is of type ACS/ACC 617, or the drive is equipped with EMC filtering,
common mode filter (three toroidal cores per each motor cable), du/dt filter or sine
output filter.
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! The drive may cause radio interference if used in a residential or domestic
environment. The user is required to take measures to prevent interference, in addition
to the requirements for CE compliance listed above, if necessary.
1. The drive is not of type ACS/ACC 617, or the drive is not equipped with EMC
filtering, common mode filter (three toroidal cores per each motor cable), du/dt filter
or sine output filter.
2. 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 can be used.
