Low-Voltage Directive 2006/95/EC.
Low-Voltage Directive
The inverters comply with the following standards listed in the
official journal of the EU:
•
EN 60204
Safety of machinery, electrical equipment of machines
• EN 61800-5-1
Electrical power drive systems with variable speed – Part 5-1:
Requirements regarding safety – electrical, thermal, and
energy requirements
UL listing

Machinery Directive
The inverters are suitable for installation in machines. Compli-
ance with the Machinery Directive 2006/42/EC requires a sepa-
rate certificate of conformity. This must be provided by the plant
construction company or the organization marketing the
machine.
EMC Directive
• EN 61800-3
Variable-speed electric drives
Part 3: EMC product standard including specific test methods
The EMC product standard EN 61800-3 for electric drive sys-
tems has been valid since July 1, 2005. The transition period for
the predecessor standard EN 61800-3/A11 dated February
2001 ended on October 1, 2007. The following information
applies to Siemens SINAMICS G110 inverters:
•
The EMC product standard EN 61800-3 does not apply
directly to a frequency inverter but to a PDS (Power Drive
System), which comprises the complete circuitry, motor and
cables in addition to the inverter.
•
Frequency inverters are normally only supplied to experts for
installation in machines or systems. A frequency inverter must,
therefore, only be considered as a component which, on its
own, is not subject to the EMC product standard EN 61800-3.
The inverter's operating instructions, however, specifies the
conditions regarding compliance with the product standard if
the frequency inverter is expanded to a PDS. For a PDS, the
EMC Directive in the EU is complied with by observing the
product standard EN 61800-3 for variable-speed electric drive
systems. The frequency inverters on their own do not
generally require identification according to the EMC
Directive.
•
In the Standard EN 61800-3 of July 2005, a distinction is no
longer made between "general availability" and "restricted
availability". Instead, different categories C1 to C4 have been
defined in accordance with the environment of the PDS at the
operating location:
-
Category C1:
Drive systems for rated voltages <1000 V for
use in the first environment
-
Category C2:
Stationary drive systems not connected by
means of a plug connector for rated voltages <1000 V. When
used in the first environment, the system must be installed
and commissioned by personnel familiar with EMC require-
ments. A warning note is required.
-
Category C3:
Drive systems for rated voltages <1000 V for
exclusive use in the second environment. A warning note is
required.
-
Category C4:
Drive systems for rated voltages
≥
1000 V or
for rated currents
≥
400 A or for use in complex systems in
the second environment. An EMC plan must be created.
•
The EMC product standard EN 61800-3 also defines limit
values for conducted interference and radiated interference
for the "second environment" (= industrial power supply
systems that do not supply households). These limit values
are below the limit values of filter class A to EN 55011. Unfil-
tered inverters can be used in industrial environments as long
as they are part of a system that contains line filters on the
higher-level infeed side.
•
With SINAMICS G110, Power Drive Systems (PDS) that fulfill
the EMC product standard EN 61800-3 can be configured
when observing the installation instructions in the product
documentation. The table "Overview of SINAMICS G110
components and PDS categories" and the SINAMICS G110
ordering documentation show which of the components can
be installed directly in a PDS.
•
A differentiation must be made between the product
standards for electrical drive systems (PDS) of the range of
standards EN 61800 (of which Part 3 covers EMC topics) and
the product standards for the devices/systems/machines, etc.
This will probably not result in any changes in the practical use
of frequency inverters. Since frequency inverters are always
part of a PDS and these are part of a machine, the machine
manufacturer must observe various standards depending on
their type and environment (e.g. EN 61000-3-2 for line
harmonics and EN 55011 for radio interference). The product
standard for PDS on its own is, therefore, either insufficient or
irrelevant.
•
With respect to the compliance with limits for line supply
harmonics, the EMC product standard EN 61800-3 for PDS
refers to compliance with the EN 61000-3-2 and
EN 61000-3-12 standards.
•
Regardless of the configuration with SINAMICS G110 and its
components, the machine construction company (OEM) can
also apply other measures to ensure that the machine
complies with the EU EMC Directive. The EU EMC Directive is
generally fulfilled when the relevant EMC product standards
are observed. If they are not available, the generic standards
(e.g. DIN EN 61000-x-x) can be used instead. It is important
that the conducted and emitted interference at the line
connection point and outside the machine remain below the
relevant limit values. Any suitable measures can be applied to
ensure this.
