  • Page 3: Safety Precautions

    DANGER • If a communications error occurs on a DeviceNet network, faulty nodes will behave as follows: (1) The master node (QJ71DN91) holds input data which had been received from slave nodes before the error occurred. (2) Whether output signals of a slave node are turned off or held is determined by the slave node's specifications or the parameters set at the master node.
  • Page 4 [INSTALLATION PRECAUTIONS] CAUTION • Use the programmable controller in an environment that meets the general specifications contained in the User's Manual of the CPU module used. Using it in an environment that does not meet them may result in an electric shock, fire, malfunction, and damage to or deterioration of the product.
  • Page 5 [STARTUP/MAINTENANCE PRECAUTIONS] DANGER • Do not touch any terminal unless all phases of the external power supply have been shut off. Doing so may cause a malfunction. • Always turn off all phases of the external power supply before cleaning or retightening the terminal screws.
