Page 3: Safety Precautions
SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the user’s manual for the CPU module used.
Page 4 [Design Precautions] WARNING ● To set a refresh device in the network parameter, select the device Y for the remote output (RY) refresh device ("Remote Output (RY)"). If a device other than Y, such as M and L, is selected, the CPU module holds the device status even after its status is changed to STOP.
Page 5 [Wiring Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before installation and 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 6 [Startup and Maintenance Precautions] WARNING ● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. ● Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the terminal screws or module fixing screws.
