SAFETY PRECAUTIONS(Read these precautions before use.)Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and payattention to safety in order to handle the product correctly.This manual classifies the safety precautions into two categories: [WARNING] and [CAUTION].WARNINGIndicates that incorrect handling may cause hazardous conditions, resulting indeath or severe injury.CAUTIONIndicates that incorrect handling may cause hazardous conditions, resulting inminor or moderate injury or property damage.Depending on the circumstances, procedures indicated by [CAUTION] may also cause severe injury.It is important to follow all precautions for personal safety.Store this manual in a safe place so that it can be read whenever necessary. Always forward it to the end user.[DESIGN PRECAUTIONS]WARNING Make sure to set up the following safety circuits outside the PLC to ensure safe system operationeven during external power supply problems or PLC failure. Otherwise, malfunctions may causeserious accidents.- Most importantly, set up the following: an emergency stop circuit, a protection circuit, an interlockcircuit for opposite movements (such as forward vs. reverse rotation), and an interlock circuit toprevent damage to the equipment at the upper and lower positioning limits.- Note that when the CPU module detects an error, such as a watchdog timer error, during selfdiagnosis, all outputs are turned off. Also, when an error that cannot be detected by the CPUmodule occurs in an input/output control block, output control may be disabled. External circuitsand mechanisms should be designed to ensure safe machine operation in such a case.- Note that the output current of the 24 V DC service power supply varies depending on the modeland the absence/presence of extension modules. If an overload occurs, the voltage automaticallydrops, inputs in the PLC are disabled, and all outputs are turned off. External circuits andmechanisms should be designed to ensure safe machine operation in such a case.- Note that when an error occurs in a relay or transistor of an output circuit, the output might stay onor off. For output signals that may lead to serious accidents, external circuits and mechanismsshould be designed to ensure safe machine operation. Construct an interlock circuit in the program to ensure safe operation for the whole system whenexecuting control (for data change) of the PLC in operation.Read the manual thoroughly and ensure complete safety before executing other controls (for programchange, parameter change, forced output and operation status change) of the PLC in operation.Otherwise, the machine may be damaged and accidents may occur due to erroneous operations. In an output circuit, when a load current exceeding the current rating or an overcurrent caused by aload short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure anexternal safety circuit, such as a fuse. For the operating status of each station after a communication failure of the network, refer to relevantmanuals for the network. Incorrect output or malfunction may result in an accident.1
[DESIGN PRECAUTIONS]CAUTION After the CPU module is powered on or is reset, the time taken to enter the RUN status variesdepending on the system configuration, parameter settings, and/or program size.Design circuits so that the entire system will always operate safely, regardless of this variation in time.[INSTALLATION PRECAUTIONS]CAUTION Connect the expansion board and expansion adapter securely to their designated connectors. Looseconnections may cause malfunctions. Connect the extension cables, peripheral device cables, input/output cables and battery connectingcable securely to their designated connectors. Loose connections may cause malfunctions. When using an SD memory card, insert it into the SD memory card slot. Check that it is insertedcompletely. Poor contact may cause malfunction. Turn off the power to the PLC before attaching or detaching the following devices. Failure to do somay cause device failures or malfunctions.- Peripheral devices, expansion board and expansion adapter- Extension modules, bus conversion module and connector conversion module- Battery[WIRING PRECAUTIONS]CAUTION Do not bundle the power line, control line and communication cables together with or lay them close tothe main circuit, high-voltage line, load line or power line. As a guideline, lay the power line, controlline and connection cables at least 100 mm (3.94") away from the main circuit, high-voltage line, loadline or power line. Noise may cause malfunctions.2
[STARTUP AND MAINTENANCE PRECAUTIONS]WARNING Do not touch any terminal while the PLC's power is on. Doing so may cause electric shock ormalfunctions. Before modifying the program in mid-operation, forcing output, running or stopping the PLC, read thismanual and the associated manuals carefully and ensure complete safety. An operation error maydamage the machinery or cause accidents. Do not change the program in the PLC from two or more peripheral equipment devices (such as anengineering tool and a GOT) at the same time. Doing so may cause destruction or malfunction of thePLC program. Use the battery for memory backup in conformance to the FX5 User's Manual (Hardware).- Use the battery for the specified purpose only.- Connect the battery correctly.- Do not charge, disassemble, heat, put in fire, short-circuit, connect reversely, weld, swallow orburn the battery, or apply excessive force (vibration, impact, drop, etc.) to the battery.- Do not store or use the battery at high temperatures or expose to direct sunlight.- Do not expose to water, bring near fire or touch liquid leakage or other contents directly.Incorrect handling of the battery may cause excessive heat, bursting, ignition, liquid leakage ordeformation, and lead to injury, fire or failures and malfunction of facilities and other equipment.[PRECAUTIONS IN OPERATION]CAUTION Construct an interlock circuit in the program to ensure safe operation for the whole system whenexecuting control (for data change) of the PLC in operation. Read the manual thoroughly and ensurecomplete safety before executing other controls (for program change, parameter change, forcedoutput and operation status change) to the PLC in operation. Otherwise, the machine may bedamaged and accidents may occur by erroneous operations.3
