  • Page 3 [DESIGN PRECAUTIONS] DANGER (2) When the PLC detects the following problems, it will stop calculation and turn off all output in the case of (a). In the case of (b), it will stop calculation and hold or turn off all output according to the parameter setting.
  • Page 4 [DESIGN PRECAUTIONS] DANGER When connecting a peripheral device to the CPU module or connecting a personal computer or the like to the intelligent function module to exercise control (data change) on the running PLC, configure up an interlock circuit in the sequence program to ensure that the whole system will always operate safely.
  • Page 5 [INSTALLATION PRECAUTIONS] CAUTION Use the PLC in an environment that meets the general specifications contained in this manual. Using this PLC in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product. Hold down the module loading lever at the module bottom, and securely insert the module fixing latch into the fixing hole in the base unit.
  • Page 6 [WIRING PRECAUTIONS] DANGER Completely turn off the external power supply when installing or placing wiring. Not completely turning off all power could result in electric shock or damage to the product. When turning on the power supply or operating the module after installation or wiring work, be sure that the module's terminal covers are correctly attached.
  • Page 7 [STARTUP AND MAINTENANCE PRECAUTIONS] DANGER Do not touch the terminals while power is on. Doing so could cause shock or erroneous operation. Correctly connect the battery. Also, do not charge, disassemble, heat, place in fire, short circuit, or solder the battery. Mishandling of battery can cause overheating or cracks which could result in injury and fires.
