Unless explicitly specified otherwise, the following technical specifications are valid for all the following components of the SINAMICS G120 standard inverters.

¹⁾ In product packaging.

²⁾ In transport packaging.

³⁾ SIPLUS components for extreme requirements are available. Additional information is available on the Internet at http://www.siemens.de/siplus-drives

⁴⁾ Applies to all PM240‑2, PM240 and PM250 Power Modules with integrated line filter class A.

⁵⁾ Non-filtered devices are designed for operation on IT systems or in conjunction with an RCD. The customer must provide suitable RI suppression equipment to ensure that these devices comply with the limits defined for Category C3 or C2.

⁶⁾ Max. permissible cable lengths see section Power Modules в†’ Integration.

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 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 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 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 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.
• 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 systems that do not supply households). These limit values are below the limit values of filter class A acc. to EN 55011. Unfiltered 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 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 G120 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 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 voltage 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 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.
