  • Page 2 SAFETY PRECAUTIONS (Read these precautions before using.) When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in this manual. Also pay careful attention to safety and handle the module properly. These SAFETY PRECAUTIONS classify the safety precautions into two categories: "DANGER" and "CAUTION".
  • Page 3 [DESIGN PRECAUTIONS] DANGER When overcurrent which exceeds the rating or caused by short-circuited load flows in the output module for a long time, it may cause smoke or fire. To prevent this, configure an external safety circuit, such as fuse. Build a circuit that turns on the external power supply when the PLC main module power is turned on.
  • Page 4 [DESIGN PRECAUTIONS] CAUTION Do not bunch the control wires or communication cables with the main circuit or power wires, or install them close to each other. They should be installed 100 mm (3.94 inch) or more from each other. Not doing so could result in noise that would cause erroneous operation. When controlling items like lamp load, heater or solenoid valve using an output module, large current (approximately ten times greater than that present in normal circumstances) may flow when the output is turned OFF to ON.
  • Page 5 [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 6 [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.
  • Page 7 [DISPOSAL PRECAUTIONS] CAUTION When disposing of this product, treat it as industrial waste. [TRANSPORTATION PRECAUTIONS] CAUTION When transporting lithium batteries, make sure to treat them based on the transport regulations. (Refer to Appendix 5 for details of the controlled models.)
