    SAFETY PRECAUTIONS (Read these precautions before use.) Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety in order to handle the product correctly. This manual classifies the safety precautions into two categories: [ WARNING] and [ CAUTION].
  • Page 4 [DESIGN PRECAUTIONS] CAUTION ● When an inductive load such as a lamp, heater, or solenoid valve is controlled, a large current (approximately ten times greater than normal) may flow when the output is turned from off to on. Take proper measures so that the flowing current dose not exceed the value corresponding to the maximum load specification of the resistance load.
  • Page 5 [WIRING PRECAUTIONS] WARNING ● Make sure to cut off all phases of the power supply externally before attempting installation or wiring work. Failure to do so may cause electric shock or damage to the product. ● Make sure to attach the terminal cover, provided as an accessory, before turning on the power or initiating operation after installation or wiring work.
  • Page 6 ● Do not disassemble or modify the PLC. Doing so may cause fire, equipment failures, or malfunctions. For repair, contact your local Mitsubishi Electric representative. ● Turn off the power to the PLC before connecting or disconnecting any extension cable. Failure to do so may cause device failures or malfunctions.
  • Page 7 [TRANSPORTATION PRECAUTIONS] CAUTION ● The PLC is a precision instrument. During transportation, avoid impacts larger than those specified in the general specifications of the User's Manual (Hardware) of the CPU module used by using dedicated packaging boxes and shock-absorbing palettes. Failure to do so may cause failures in the PLC.
