Appendix A – ACS/ACC/ACP 601 Technical Data
ACS/ACC/ACP 601 Frequency Converters A-25
CE Marking
A CE mark is attached to ACx 601/607 frequency converters 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).
Compliance with the
EMC Directive
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 in European Economic Area. The EMC product standard EN 61800-3
covers the requirements stated for frequency converters.
The ACx 601 frequency converters comply with the EMC Directive in industrial low-
voltage network, public low-voltage network (restricted distribution) and IT networks
(unearthed mains) with the following provisions:
Industrial Low-Voltage
Network
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 ACx 600 can be equipped with EMC filtering
(refer to Table A-1) or the supply transformer with static screening between the
primary and secondary windings can be used.
2. The ACx 601 is installed with motor and control cables as specified in this
manual.
Note:
It is recommended to equip the ACx 600 with the EMC filtering if there is
equipment sensitive to conducted emission connected to the same supply transformer
as the ACx 600.
