    Encoder systems and temperature sensors are electrostatic sensitive devices (ESD). Do not touch the connections with either hands or tools that could be electrostatically charged! ● We recommend that SIEMENS prefabricated cables are used (not included in the scope of delivery). These cables reduce installation costs and increase operational reliability (see the Configuration Manual).
  • Page 31 Connecting 6.1 Electrical connection ● Take measures to ensure that connecting cables cannot rotate, are not subject to strain and pushing force and also provide anti-kink protection. It is not permissible to subject the connector to continuous force. ● The coding groove of the plug-in connection must be inserted so that it is aligned in the socket connector and the screw cap must be tightened by hand as far as it will go.
