52 E-DC Hardware Installation Guide Appendix B – EMC Installation Guide
General Product Philosophy
Meeting requirements for electromagnetic compatibility (EMC) compliance will
require specific measures to be taken during installation of the E-DC Drive. The
ultimate responsibility for ensuring that the EMC requirements are met rests with
the systems builder.
It is important to remember that for specific installations, the full protection
requirements of the EMC Directive 89/336/EEC need to be met before the system
is put into service. This must be verified either by inspection or by testing. The
following EMC installation recommendations are intended to assist in ensuring
that the requirements of the EMC directive are met. It may be necessary to take
additional measures in certain circumstances and at specific locations.
Although these recommendations are based on expertise acquired during tests
carried out on the E-DC Drive, it is impossible for Compumotor to guarantee the
compliance of any particular installation. Compliance will be strongly influenced
by the physical and electrical details of the installation and the performance of
other system components. Nevertheless it is important to follow all the installation
instructions if an adequate level of compliance is to be achieved.
Safety Considerations
These products are intended for installation according to the appropriate safety
procedures including those laid down by the local supply authority regulations.
The recommendations provided are based on the requirements of the Low Voltage
Directive and specifically on EN61010. It should be remembered that safety must
never be compromised for the purpose of achieving EMC compliance. Therefore
in the event of a conflict occurring between the safety regulations and the follow-
ing recommendations, the safety regulations always take precedence.
General Considerations
External Enclosures
The measures described in these recommendations are primarily for the purpose of
controlling conducted emissions. To control radiated emissions, all drive and
control systems must be installed in a steel equipment cabinet which will give
adequate screening against radiated emissions. This external enclosure is also
required for safety reasons. There must be no user access while the equipment is
operating. This is usually achieved by fitting an isolator switch to the door
assembly. The E-DC Drive must be mounted to a conductive, earthed panel. If this
has a paint finish, it will be necessary to remove the paint in certain areas where
specified.
To achieve adequate screening of radiated emissions, all panels of the enclosure
must be bonded to a central earth point. The enclosure may also contain other
equipment and the EMC requirements of these must be considered during installa-
tion. Always ensure that drives are mounted in such a way that there is adequate
ventilation.
