Compliance with standards

CE marking

The MICROMASTER inverters meet the requirements of the Low-Voltage Directive 73/23/EEC.

Low-voltage directive

The inverters comply with the following standards listed in the Official Journal of the European Communities: 

• EN 60 204

Safety of machinery, electrical equipment of machines

• EN 61 800-5-1

Electrical power drive systems with variable speed - Part 5-1: Requirements regarding safety - electrical, thermal and energy requirements

Machine directive

The inverters are suitable for installation in machines. Compliance with the machine directive 89/392/EEC requires a separate certificate of conformity. This must be furnished by the plant constructor or the installer of the machine.

EMC directive

• EN 61 800-3

Variable-speed electric drives
Part 3: EMC product standard including special test procedure.

The new EMC product standard EN 61 800-3 applies to electrical drive systems as of July 1, 2005. The transition period for the preceding standard EN 61 800-3/A11 dated February 2001 ends on October 1, 2007. The following explanations apply to frequency inverters of the 6SE6 series from Siemens:

• The EMC product standard EN 61 800-3 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.
• As a rule, frequency inverters are only supplied to qualified technical specialists for installation in machines or plants. A frequency inverter must therefore only be considered as a component which, as such, is not subject to the EMC product standard EN 61 800-3. However, the inverter''s instruction manual specifies the conditions under which the product standard can be complied with if the frequency inverter is expanded to become a PDS. For a PDS, the EMC directive in the EU is complied with through observance of the product standard EN 61 800-3 for variable-speed electrical drive systems. The frequency inverters on their own do not generally require marking according to the EMC directive.
• The new EN 61 800-3 of July 2005 no longer distinguishes between "general availability" and "restricted availability". Instead, different categories, namely C1 to C4, are defined according to the environment of the PDS at the place of use:
  • Category C1:
    Drive systems for rated voltages of < 1000 V for use in the first environment
  • Category C2:
    Fixed-location drive systems which are not connected by means of plug-in devices, for rated voltages of < 1000 V. if used in the first environment, installation and start-up may only be carried out by qualified EMC personnel. Warning information must be provided.
  • Category C3:
    Drive systems for rated voltages of < 1000 V, solely for use in the second environment. Warning information must be provided.
  • Category C4:
    Drive systems for rated voltages of ≥ 1000 V or for rated currents of ≥ 400 A or for use in complex systems in the second environment. An EMC plan must be drawn up.
• In the EMC product standard EN 61 800-3, limits for conducted interference voltages and radiated interference are also indicated for the so-called "second environment" (= industrial power supply systems which do not supply households). These limits are lower than the limits of filter class A according to EN 55 011. The use of unfiltered inverters in an industrial environment is permissible provided they are part of a system that is equipped with line filters on the higher-level infeed side.
• With MICROMASTER, power drive systems (PDS) which comply with EMC product standard EN 61 800-3 can be installed (see the installation instructions in the product documentation). The table entitled "Overview of MICROMASTER components and PDS categories" and the MICROMASTER ordering documents show which components the respective PDS installation supports directly. 
• In general, a distinction must be made between the product standards for electrical drive systems (PDS) of the EN 61 800 series of standards (of which Part 3 covers EMC topics) and the product standards for 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 the latter is part of a machine, the manufacturer of the machine must observe various standards depending on the type of machine and the environment, e.g. EN 61 000-3-2 for power supply harmonics and EN 55 011 for radio interference. The PDS product standard alone is therefore inadequate or irrelevant.
• With regard to compliance with limits for power supply harmonics, the EMC product standard EN 61 800-3 for PDS refers to compliance with the EN 61 000-3-2 and EN 61 000-3-12 standards.
• Irrespective of configuration with MICROMASTER and its components, the machine builder can also modify the machines in other ways in order to comply with the EMC directive of the EU. As a rule, the EMC directive of the EU is observed through compliance with the EMC product standards applicable to the machine. If they are not available, the generic standards such as DIN EN 61 000-x-x can be used instead. What is important is that the conducted interference and the radiated interference voltages at the power-supply connection point and outside the machine remain below the corresponding limits. What technical means are used to ensure this is not prescribed.
