The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions.
Page 14: Warnings
Safety Precautions Warnings WARNING During Power Supply Do not touch the terminal section while power is ON. Electric shock may occur. Do not attempt to take any Unit apart. In particular, high-voltage parts are present in Units that supply power while power is sup- plied or immediately after power is turned OFF.
Page 15: Cautions
Safety Precautions Voltage and Current Inputs Make sure that the voltages and currents that are input to the Units and slaves are within the specified ranges. Inputting voltages or currents that are outside of the specified ranges may cause accidents or fire.
Page 16 Safety Precautions Online Editing Execute online editing only after confirming that no adverse effects will be caused by devia- tions in the timing of I/O. If you perform online editing, the task execution time may exceed the task period, I/O may not be refreshed with external devices, input signals may not be read, and output timing may change.
Page 17: Precautions For Safe Use
Precautions for Safe Use Precautions for Safe Use Transporting • When transporting any Unit, use the special packing box for it. Also, do not subject the Unit to excessive vibration or shock during transportation. • Do not drop any Unit or subject it to abnormal vibration or shock. Doing so may result in Unit malfunction or burning.
Page 18 Precautions for Safe Use Wiring • Double-check all switches and other settings and double-check all wiring to make sure that they are correct before turning ON the power supply. Use the correct wiring parts and tools when you wire the system. •...
Page 19 Precautions for Safe Use Actual Operation • Before you start operation, always register the NX Units that are connected to the Communications Coupler Unit in the host communications master as the Unit Configuration Information. • Check the user program, data, and parameter settings for proper execution before you use them for actual operation.
Page 20 Precautions for Safe Use Sysmac Studio and you can check the actual slave revisions from the Sysmac Studio or on slave nameplates. • After you transfer the user program, the CPU Unit is restarted and communications with the Ether- CAT slaves are cut off. During that period, the slave outputs behave according to the slave settings. The time that communications are cut off depends on the EtherCAT network configuration.
Page 21: Precautions For Correct Use
Precautions for Correct Use Precautions for Correct Use Storage, Mounting, and Wiring • Follow the instructions in this manual to correctly perform installation. • Do not operate or store the Units in the following locations. Doing so may result in malfunction, in operation stopping, or in burning.
Page 22: Regulations And Standards
Concepts  EMC Directives OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards.*1 Whether the products conform to the standards in the system used by the customer, however, must be checked by the customer.

7 Digital Output Units 7-4-3 Load Short-circuit Protection Purpose This function is used to protect the output circuits of the Digital Output Units when an external connec- tion load short-circuit occurs. Details on the Function As shown in the figure below, normally when the output bit (OUT) turns ON, the transistor turns ON and then output current (Iout) will flow.
Page 191 7 Digital Output Units  Restrictions on Use The load short-circuit protection function only protects internal circuits for a short period. As shown in the figure above, the load short-circuit protection of this NX Unit is automatically released when the Tj equals to Tr. Therefore, unless the cause of short-circuit is removed, ON/OFF operations are repeated in the out- put.

Contact Protec- tion Circuit on page 7-22). Be sure to connect a contact protection circuit in parallel with every DC inductive load that is connected to the Contact Output Unit because the usage of a contact protection circuit has a significant effect on the service life of the contact.
