  • Page 3 SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using the product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. In this manual, the safety precautions are classified into two levels: " WARNING"...
  • Page 4 [DESIGN PRECAUTIONS] WARNING Configure a circuit so that the programmable controller is turned on first and then the external power supply. If the external power supply is turned on first, an accident may occur due to an incorrect output or malfunction. For the operating status of each station after a communication failure, refer to relevant manuals for the network.
  • Page 5 [INSTALLATION PRECAUTIONS] CAUTION Use the programmable controller under the environment that meets the general specifications in this manual. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product. To mount the CPU module, while pressing the module mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place.
  • Page 6 [WIRING PRECAUTIONS] WARNING Shut off the external power supply for the system in all phases before wiring. Failure to do so may result in electric shock or damage to the product. After wiring, attach the included terminal cover to the module before turning it on for operation. Failure to do so may result in electric shock.
  • Page 7 Do not remove the film during wiring. Remove it for heat dissipation before system operation. Mitsubishi Electric programmable controllers must be installed in control panels. Connect the main power supply to the power supply module in the control panel through a relay terminal block.
  • Page 8 [STARTUP AND MAINTENANCE PRECAUTIONS] WARNING Do not touch any terminal while power is on. Doing so will cause electric shock. Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Doing so will cause the battery to produce heat, explode, or ignite, resulting in injury and fire. Shut off the external power supply for the system in all phases before cleaning the module or retightening the terminal screws or module fixing screws.
  • Page 9 [STARTUP AND MAINTENANCE PRECAUTIONS] CAUTION Before performing online operations (especially, program modification, forced output and operation status change) for the running CPU module from the peripheral connected, read relevant manuals carefully and ensure the safety. Improper operation may damage machines or cause accidents. Do not disassemble or modify the modules.
