  • Page 272 Appendix A.1 The article number system Z options For some positions of the article number, a more detailed selection can be useful or necessary. For example, when selecting a communication connection (position 9), the communication module (PROFIBUS, PROFINET, etc.) must be defined. This is done with the Z options that are appended to the article number.
  • Page 273 Appendix A.1 The article number system Z option digital signaling switch As standard, every ETU is delivered with a ready-to-close signaling switch (RTC) with four auxiliary switches AUX 4CO and one tripped signaling switch (S24) with a standard contact. These accessories can optionally also be ordered with digital and mixed contacts. You will find more information in the catalogs for 3WL10 and 3VA27 (see Chapter Reference documents (Page 10)).

  • Page 279: Esd Guidelines

    ESD guidelines Electrostatic sensitive devices (ESD) ESD components are destroyed by voltage and energy far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged. ESD components which have been subject to such voltage are usually not recognized immediately as being defective, because the malfunction does not occur until after a longer period of operation.
