Abide by the specifications for a communication distance and the number of Units to be connected. When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may result in malfunction or burning. Before touching the Unit, be sure to first touch a grounded metallic object in order to discharge any static built-up. Not doing so may result in malfunction or damage. Use a dedicated packing box to transport the Unit. Avoid excessive shock or vibration during transportation. Always use two end plates to keep certainly connection side by side (E3X-CRT). When connecting the Power Supply Unit, CPU Unit, I/O Units, Special I/O Units, or CPU Bus Units, slide the upper and lower sliders until a click sound is heard to lock them securely. Desired functionality may not be achieved unless Units are securely locked in place. Be sure to mount the end cover supplied with the CPU Unit to the rightmost Unit. Unless the end cover is properly mounted, the CJ-series PLC may not function properly. Please be sure to read the related user manuals in order to use the PLC safely and properly. Be sure you are using the most current version of the manual. ? Thank you for purchasing an OMRON CRT1-series Slave Unit. To ensure safe operation, please be sure to read this document along with the manuals for CRT1-series Slave Units. Please be sure you are using the most recent versions of the user manuals. Contact your nearest OMRON representative to obtain manuals. Keep this document and all user manuals in a safe location and be sure that they are readily available to the final user of the products. The user must operate the product according to the performance specifications described in the operation manuals. Before using the product under conditions which are not described in the manual or applying the product to nuclear control systems, railroad systems, aviation systems, vehicles, combustion systems, medical equipment, amusement machines, safety equipment, petrochemical plants, and other systems, machines, and equipment that may have a serious influence on lives and property if used improperly, consult your OMRON representative. Make sure that the ratings and performance characteristics of the product are sufficient for the systems, machines, and equipment, and be sure to provide the systems, machines, and equipment with double safety mechanisms. Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system. The PLC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system. When the 24-VDC output (service power supply to the PLC) is overloaded or shortcircuited, the voltage may drop and result in the outputs being turned OFF. As a countermeasure for such problems, external safety measures must be provided to ensure safety in the system. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury, or property damage. Do not attempt to take any Unit apart while the power is being supplied. Doing so may result in electric shock. Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock. Provide safety measures in external circuits, i.e., not in the Programmable Controller (CPU Unit including associated Units;
