  • Page 4 [Design Precautions] WARNING ● In an output module, when a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.
  • Page 5 [Installation Precautions] CAUTION ● Use the programmable controller in an 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 module, while pressing the module mounting lever 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 Pulling the connected cable can result in malfunction or damage of the module or the cable. ● 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. Wiring and replacement of a power supply module must be performed by maintenance personnel who is familiar with protection against electric shock.
  • Page 7 [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, or apply liquid or a strong shock to the battery. Doing so will cause the battery to produce heat, explode, ignite, or liquid spill, resulting in injury and fire.
  • Page 8 [Disposal Precautions] CAUTION ● When disposing of this product, treat it as industrial waste. When disposing of batteries, separate them from other wastes according to the local regulations. (For details of the Battery Directive in EU countries, refer to Page 678, Appendix 12.)

  • Page 31 CHAPTER 1 OVERVIEW (4) Increase in debugging efficiency through high-speed communication with a programming tool High-speed communications at 115.2Kbps maximum are available by using RS-232 which reducing the time required for writing and reading of programs and monitoring. Also, the communication time efficiency of debugging has been increased.
  • Page 32 (7) Connection of up to 7 extension base units Up to seven extension base units can be connected to the Q series CPU module. The overall extension cable length is 13.2m, which allows flexible layout of base units. (8) Memory extension By extending the memory capacity of a CPU module, large size files can be managed.
  • Page 33 CHAPTER 1 OVERVIEW (9) Automatic write to the standard ROM Note 1.1 Note 1.2 Note 1.1, Note 1.2 Parameters and programs in a memory card or SD memory card can be written to the standard ROM of the CPU module without using a programming tool. If the boot operation is being performed from the standard ROM, parameters and programs in a memory card or SD memory card can be written to the standard ROM by inserting it to the CPU module.
  • Page 34 (14)Support of redundant power supply systems The redundant power supply system can be configured using a redundant base unit and redundant power supply modules. The system can continue operation even if one of the power supply modules fails, since the other will supply the power.
