The specialistsmust be familiar with the current norms and guidelines for the devices andautomated environments.All changes to the coupler or controller should always be carried out by qualifiedpersonnel with sufficient skills in PLC programming.Pos : 18.5 /Serie 750 (WAGO-I/O-SYST EM)/Wic htige Erläuterungen/Bes timmungsgemäß e Verwendung 750- xxxx @ 3\mod_1224064151234_21.doc x @ 24070 @ 3 @ 12.1.3 Use of the 750 Series in Compliance with UnderlyingProvisionsCouplers, controllers and I/O modules found in the modular WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and transmit themto the actuators or higher-level control systems. Using programmable controllers,the signals can also be (pre-) processed.The components have been developed for use in an environment that meets theIP20 protection class criteria. Protection against finger injury and solid impuritiesup to 12.5 mm diameter is assured; protection against water damage is notensured. Unless otherwise specified, operation of the components in wet anddusty environments is prohibited.Operating 750 Series components in home applications without further measuresis only permitted if they meet the emission limits (emissions of interference)according to EN 61000-6-3. You will find the relevant information in the sectionon "WAGO-I/O-SYSTEM 750" "System Description" "Technical Data" inthe manual for the used fieldbus coupler/controller.
