This is a summary of the EMC performance of the Drive. For full details,
refer to the
Dinverter A EMC Data Sheet
which can be obtained from a Drive
Centre or distributor listed at the end of this User Guide.
Immunity
Compliance with immunity standards does not depend on installation
details. Single and parallel Drive modules meet EN50082–2 (generic
immunity standard for the industrial environment) and the following
specifications from the IEC1000–4 group (derived from IEC801):
Part 2, Electrostatic discharge: Level 3
Part 3, Radio frequency field: Level 3
Part 4 Transient burst:
Level 4 at the control terminals
Level 3 at the power terminals
Part 5, Surge (at the
AC
supply terminals) (as specified by EN50082–2
informative annex):
Level 4 line-to-ground
Level 3 line-to-line
Part 6, Conducted radio frequency: Level 3
Emission
Compliance with emission standards depends on rigorous adherence to the
installation guidelines, including the use of the specified RFI filter in the
AC
supply circuit. Compliance also depends on the PWM switching frequency
used in the output stage of the Drive, and the length of the motor cable.
For full details, refer to the
Dinverter A EMC Data Sheet
which can be obtained
from a Drive Centre or distributor listed at the end of this User Guide.
Conducted emission from the Drive meets the requirements of EN50081–2
(generic emission standard for the industrial environment) over a wide range
of conditions. In addition, the Drive meets the radiated emission
requirements of this standard. The emission limits in EN50081–2 are similar
to CISPR11 and EN55011 Class A.
Under restricted conditions, the conducted emission meets EN50081–1
(generic emission standard for the residential, commercial and light
industrial environment. This is similar to CISPR11 and EN55011 Class B.
The optional RFI filter model number DIN 1012F must be used.
