4.1 EMC
considerations
Depending on the requirements of the installation, one of the following
levels of electromagnetic compatibility (EMC) should be adopted:
Routine EMC precautions
These precautions are recommended when strict compliance with
emission standards is not required. The risk of disturbing adjacent
electronic equipment is minimized by adopting these precautions.
Compliance with EMC emission standards
These precautions are recommended when strict compliance with
emission standards is required. In addition, it is recommended that
these precautions are taken when the Drive is installed in a residential
area, or adjacent to sensitive electronic equipment such as radio
receivers or similar.
Compliance with EN61800-3 (standard for Power Drive Systems)
Meeting the requirements of this standard depends on the
environment that the Drive is intended to operate in, as follows:
Operation in the first environment
Observe the guidelines given in
Power Drives System standard
in
Chapter 3
Data
. An RFI filter will always be required.
Operation in the second environment
An RFI filter may not be required. Follow the guidelines given in
Power
Drives System standard
later in this chapter depending on the
requirements of the end user.
Caution
The second environment typically includes an industrial low-
voltage power supply network which does not supply
buildings used for domestic purposes. Operating the Drive
in this environment without an RFI filter may cause
interference to nearby electronic equipment whose
sensitivity has not been appreciated. The user must take
remedial measures if this situation arises. If the
consequences of unexpected disturbances are severe, it is
recommended that the emission limits of EN50081-2 be
adhered to.
Instructions are given later in this chapter for these levels of EMC. Refer to
Chapter 3
Data
for further information on compliance with EMC standards
and definitions of environments.
Detailed instructions and EMC information are given in the
Dinverter A
EMC
Data Sheet
which is available from the Drive Centres and distributors listed at
the end of the User Guide.
