- Page 3 SAFETY PRECAUTIONS (Be sure to read these instructions before use.) Before using the product, read this and relevant manuals carefully and handle the product correctly with full attention to safety. In this manual, SAFETY PRECAUTIONS are classified into 2 levels: "DANGER"...
- Page 4 [DESIGN PRECAUTIONS] DANGER (2) When the programmable controller detects the following error conditions, it stops the operation and turn off all the outputs. The overcurrent protection device or overvoltage protection device of the power supply module is activated. The programmable controller CPU detects an error such as a watchdog timer error by the self-diagnostics function.
- Page 5 [DESIGN PRECAUTIONS] DANGER When controlling a running programmable controller (data modification) by connecting a peripheral device to the CPU module or a PC to a special function module, create an interlock circuit on sequence programs so that the whole system functions safely all the time. Also, before performing any other controls (e.g.
- Page 6 [INSTALLATION PRECAUTIONS] CAUTION Use the programmable controller under the environment specified in the user’s manual. Otherwise, it may cause electric shocks, fires, malfunctions, product deterioration or damage. Insert the module fixing projection into the fixing hole in the base unit and then tighten the module mounting screw within the specified torque.
- Page 7 [WIRING PRECAUTIONS] DANGER Be sure to shut off all phases of the external power supply used by the system before wiring. Failure to do so may result in an electric shock or damage of the product. Before energizing and operating the system after wiring, be sure to attach the terminal cover supplied with the product.
- Page 8 [STARTUP AND MAINTENANCE PRECAUTIONS] DANGER Do not touch any terminal during power distribution. Doing so may cause an electric shock. Properly connect batteries. Do not charge, disassemble, heat or throw them into the fire and do not make them short-circuited and soldered. Incorrect battery handling may cause personal injuries or a fire due to exothermic heat, burst and/or ignition.
- Page 9 [DISPOSAL PRECAUTIONS] CAUTION When disposing of the product, treat it as an industrial waste. When disposing of batteries, separate them from other wastes according to the local regulations. (For details of the battery directive in EU member states, refer to the A1SCPU/A1SCPUC24-R2/A2SCPU User's manual.) [TRANSPORTATION PRECAUTIONS] CAUTION...
