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" and "CAUTION". Indicates that incorrect handling may cause hazardous conditions, resulting in DANGER death or severe injury.
Page 4 [DESIGN PRECAUTIONS] DANGER If load current more than the rating or overcurrent due to a short circuit in the load has flowed in the output module for a long time, it may cause a fire and smoke. Provide an external safety device such as a fuse.
Page 5 [DESIGN PRECAUTIONS] CAUTION Do not install the control lines or communication cables together with the main circuit or power lines, or bring them close to each other. Keep a distance of 100mm (3.94inch) or more between them. Failure to do so may cause malfunctions due to noise. When an output module is used to control the lamp load, heater, solenoid valve, etc., a large current (ten times larger than the normal one) may flow at the time that the output status changes from OFF to ON.
Page 6 [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 7 [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.
Page 8 CAUTION When performing online operations (especially, program modification, forced output or operating status change) by connecting a peripheral device to the running CPU module, read the manual carefully and ensure the safety. Incorrect operation will cause mechanical damage or accidents. Do not disassemble or modify each of modules.
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 Appendix 7.) [TRANSPORTATION PRECAUTIONS] CAUTION When transporting lithium batteries, make sure to treat them based on the transportation regulations.
