System configuration
SINAMICS G120P and SINAMICS G120P Cabinet pump, fan, compressor converters
SINAMICS G120P and SINAMICS G120P Cabinet pump, fan, compressor converters
Compliance with standards
CE marking
The SINAMICS G120P and SINAMICS G120P Cabinet
converters meet the requirements of the Low-Voltage Directive
2014/35/EC.
Low-Voltage Directive
The converters 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
Converters in UL category NMMS certified to UL and cUL, in
compliance with UL508C or ULC61800-5-1. UL list numbers
E121068 and E192450.
For use in environments with pollution degree 2.

Machinery Directive
The converters 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 ma-
chine.
Functional safety
SINAMICS G120P and SINAMICS G120P Cabinet are not in-
tended for use in installations with functional safety as defined
by ISO 13849-1, IEC 61508-x.
EMC Directive
• EN 61800-3
Variable-speed electric drives
Part 3: EMC product standard including specific test methods
The following explanatory information applies to
SINAMICS G120P and SINAMICS G120P Cabinet converters
supplied by Siemens AG:
•
The EMC product standard EN 61800-3 does not apply
directly to a converter but to a PDS (Power Drive System),
which comprises the complete circuitry, motor and cables in
addition to the converter.
•
Converters are normally only supplied to experts for instal-
lation in machines or systems. A converter must, therefore,
only be considered as a component which, on its own, is not
subject to the EMC product standard EN 61800-3. The
converter's operating instructions, however, specifies the
conditions regarding compliance with the product standard if
the converter is expanded to become 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 converters on their own do not generally
require identification according to the EMC Directive.
•
Different categories C1 to C4 have been defined in accor-
dance 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
systems that do not supply households). These limit values
are below the limit values of filter class A to EN 55011. Unfil-
tered converters 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 G120P and SINAMICS G120P Cabinet,
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 converters. Since converters 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. EN 61000-2-4 applies for
devices >75 A.
•
Regardless of the configuration with SINAMICS G120P and
SINAMICS G120P Cabinet 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. 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.
