ACS 160 User’s Manual 119
Appendix C
EMC Instructions and Maximum Cable Lengths
Mandatory Installation Instruction According to the EMC Directive for type ACS 160
frequency converters
EMC stands for Electromagnetic Compatibility. This is the ability of electrical and electronic
equipment to operate without problems within an electromagnetic environment and without
disturbing or interfering with nearby equipment.
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. Depending on the type of ACS 160 frequency
converters the requirements of EN 61800-3 for Second Environment and First Environment,
restricted and unrestricted distribution are met. For turther information refer to the following pages
of this appendix.
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.
The following section describes the various markings used to verify the correct usage of directives
and rules.
CE Marking
A CE mark is attached to ACS 160 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).
