ACS 400 EMC Instructions
Mandatory Installation Instruction According to the EMC Directive for type ACS 400
frequency converters
Follow the instructions given in the ACS 400 User´s Manual and the instructions delivered with
different accessories.
CE Marking
A CE mark is attached to ACS 400 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).
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. ACS 400 frequency converters comply with the
requirements stated in EN 61800-3 for Second Environment and First Environment, restricted
distribution.
Product standard EN 61800-3 (Adjustable speed electrical power drive systems - Part 3: EMC
product standard including specific test methods) defines First Environment as environment that
includes domestic premises. It also includes establishments directly connected without
intermediate transformers to a low voltage power supply network which supplies buildings used for
domestic purposes.
Second Environment includes establishments other than those directly connected to a low
voltage power supply network which supplies buildings used for domestic purposes. With ACS 400,
no RFI filter is needed in Second Environment.
C-Tick Marking
A C-tick mark is attached to the ACS 400 frequency converters to verify that the unit follows the
provisions of the Australian Statuary Rules No 294, 1996, Radiocommunication (Compliance
Labelling - Incidental Emissions) Notice and the Radiocommunication Act, 1989, and the
Radiocommunication Regulations, 1993, of New Zealand.
The statutory rules defines the essential requirements for emissions of electrical equipment used in
Australia and New Zealand. The standard AS/NZS 2064, 1997, Limits and methods of
measurement of electronic disturbance characteristics of industrial, scientific and medical (ISM)
radiofrequency equipment, covers the detailed requirements for three-phase frequency converter.
The frequency converter ACS 400 comply with the AS/NZS 2064, 1997, limits for class A
equipment. Class A equipment is suitable for use in all establishments other than domestic and
those directly connected to a low voltage network which supplies buildings used for domestic
purposes. The compliance is valid with the following provisions:
• The frequency converter is equipped with RFI-filter.
• The motor and control cables are chosen as specified in this manual.
• The installation rules of this manual are followed.
