    PRECAUTIONS This section provides general precautions for installing and using the GRT1-series Slice I/O Units and related devices. The information contained in this section is important for the safe and reliable application of the Slice I/O Units. You must read this section and understand the information contained before attempting to set up or operate a Slice I/O Terminal.

  • Page 15: Intended Audience

    It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC system to the above mentioned applica- tions.

  • Page 16: Operating Environment Precautions

    Operating Environment Precautions • The PLC outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.

  • Page 17: Application Precautions

    Application Precautions !Caution The operating environment of the PLC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System. Be sure that the operating environment is within the specified condi- tions at installation and remains within the specified conditions during the life of the system.

  • Page 18: Ec Directives

    EMC Directive OMRON devices that comply with EC Directives also conform to the related EMC standards, so that they can more easily be built in to other devices or the overall machine. The actual products have been checked for conformity to EMC standards.
  • Page 19 EC Directives the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards. Low Voltage Directive Devices that operate at voltages from 50 to 1,000 VAC or 75 to 150 VDC must satisfy the appropriate safety requirements.
