2-2 Installing the Drive
2.2 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 Compliance with
EMC emission standards. An RFI filter will always
be required. Some model sizes may require
additional filtering techniques to be applied.
Operation in the second environment
An RFI filter may not be required. Follow the
guidelines given in Routine EMC precautions or
Compliance with EMC emission standards
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 Appendix C Data for further
information on compliance with EMC standards and
definitions of environments.
Detailed instructions and EMC information are given
in the Unidrive LV EMC Data Sheet which is available
from the Drive Centres and distributors listed at the
end of this Installation Guide.
Compliance data is given in Appendix C Data.
Note
The installer of the Drive is responsible for
ensuring compliance with the EMC
regulations that apply where the Drive is to
be used.
The Drive will comply with the standards
for emission, such as EN50081–2, only when
the instructions given in Planning the
installation and Wiring recommendations later
in this chapter are followed closely.
