For compliance with the protection
objectives of the German EMC Act
(EMVG) in systems and machines, the
following EMC standards must be
satisfied:
EMC standard for drive systems
(PowerDriveSystem), interference
immunity and emissions in residential
areas, enterprise zones with light
industry and in industrial facilities.
This standard must be complied with
in the EU for satisfying the EMC
requirements for systems and
machines!
For emitted interference, the following apply:
Specialised basic standard for emissions in light industry
can be satisfied with special features (mains filters,
screened power cables) in the lower rating range *(EN 50081-1).
Specialised basic standard for emissions in industry
*(EN 50081-2)
For interference immunity, the following apply:
Specialised basic standard for interference immunity in
residential areas *(EN 50082-1)
Specialised basic standard for interference immunity in
industry. If this standard is satisfied, then the EN 61000-6-1
standard is automatically satisfied as well *(EN 50082-2)

Classification
The following overview utilises
the terminology and indicates
the action required in
accordance with Product
Standard .
For the DCS880 series, the
limit values for emitted
interference are complied
with, provided the measure
indicated is carried out. PDS of
category C2 (formerly
restricted distribution in first
environment) is intended to be
installed and commissioned
only by a professional (person
or organization with necessary
skills in installing and/or
commissioning PDS including
their EMC aspects).
For power converters without
additional components, the
following warning applies:
This is a product of category
C2 under IEC 61800-3:2004. In
a domestic/residential
environment this product may
cause radio interference in
which case supplementary
mitigation measures my be
required.
The field supply is not
depicted in this overview
diagram. For the field current
cables, the same rules apply as
for the armature-circuit
cables.
