Technical specifications
Note:
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. The frequency inverters on their own do not
generally require identification according to the EMC Directive.
Compliance with standards
CE marking
The SINAMICS G120 inverters meet the requirements of the
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
Inverter devices in UL category NMMS certified to UL and cUL,
in compliance with UL508C. UL list numbers E121068 and
E192450. This applies to all PM230 Power Modules, degree of
protection IP20 (cUL only for frame sizes FSA to FSC), PM240,
PM240-2 and PM250 Power Modules with integrated line filter
class A.
For use in environments with pollution degree 2.

Machinery Directive
The inverters are suitable for installation in machines. Compliance
with the Machinery Directive 2006/42/EC requires a separate
certificate of conformity. This must be provided by the plant con-
struction 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 following information applies to SINAMICS G120 frequency
inverters from Siemens AG:
•
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 become a PDS. For a
PDS, the EMC Directive in the EU is complied with by observ-
ing the product standard EN 61800-3 for variable-speed elec-
tric drive systems. The frequency inverters on their own do not
generally require identification according to the EMC Directive.
•
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
requirements. 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 sys-
tems that do not supply households). These limit values are
below the limit values of filter class A acc. 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 G120, 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.
•
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 fre-
quency inverters. Since frequency inverters are always part of
a PDS and these are part of a machine, the machine manufac-
turer 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 har-
monics, 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 G120 and its
components, the machine construction company (OEM) can
also apply other measures to ensure that the machine com-
plies with the EU EMC Directive. The EU EMC Directive is gen-
erally 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 supply
connection point and outside the machine remain below the
relevant limit values. Any suitable technical measures can be
applied to ensure this.
SEMI F47
SEMI F47 is an industry standard relating to the immunity to volt-
age dips. This includes the requirement that industrial equipment
must be able to tolerate defined dips or drops of the line supply
voltage. As a result, industrial equipment that fulfills this standard
is more reliable and productive. In the SINAMICS G120 product
family, the PM230, PM240, PM240-2 and PM250 Power Modules
fulfill the latest SEMI F47-0706 standard. In the case of a voltage
dip, defined in accordance with SEMI F47-0607, these drives
either continue to supply a defined output current, or using an
automatic restart function, continue to operate as expected.
