To protect against indirectly touching part of the motor circuit of a converter and to automatically shut down in the case of a fault according to DIN EN 60364-4-41 (VDE 0100-410).

  • Contribution
  • Concerne le/les produits(s)
In electrical systems that include converters, protection must be provided against electric shock for the overall system. This also includes motors fed from converters.

To release plants/machines after erection and installation and for subsequent testing, the following preconditions are provided along with an explanation for the test technician/test engineer:

Preconditions

  • The installation instructions provided in the equipment manual for the converter have been complied with, especially regarding
    • Potential bonding
    • Conductor/wire cross-section
    • Protection/fusing
  • The valid standards when installing were complied with
    • DIN EN 50178 (VDE 0160)
    • DIN EN 60204-1 (VDE 0113-1)
    • DIN EN 60364-5-52 (VDE 0100-520) and
    • DIN EN 60364-5-54 (VDE 0100-540).
  • The protective conductor is a continuous according to IEC 60364-6 (VDE 0100-600).

Manufacturer's declaration

Assuming that the previously mentioned preconditions are fulfilled, the following converter series

  • SINAMICS
  • SIMODRIVE
  • MASTERDRIVES
  • MICROMASTER
  • SIMATIC ET200pro and
  • SIMATIC ET200S

satisfy the requirements laid down in DIN EN 60364-4-41 (VDE 0100-410) and comply with the specified shut down times. See also 109476638.

The explanation is based on the following:

  • In the case of a short-circuit with negligible impedance with respect to ground, the converter interrupts the circuit within the shortest time (<< 100 ms). As a consequence, there is a very high impedance between the converter DC link and the output (> 1 MOhm) so that the possible voltage as result of the voltage divider comprising the impedance of the ground connection between the motor and converter is less than 50 VAC or 120 VDC.

 

Notes relatives à la sécurité
La protection des installations, systèmes, machines et réseaux contre les cyber-menaces nécessite la réalisation (et le maintien continu) d'un concept global de sécurité IT à la pointe de la technique. Les produits et solutions Siemens ne constituent qu'un élément d'un tel concept. Pour plus d’informations sur la cyber-sécurité, rendez-vous sur
