To prevent this, configure an external safety circuit. such as fuse O Build a circuit that turns on the external power supply when the PLc main module power is turned on. If the external power supply is turned on first, it could result in erroneous output or erroneous operation o When there are communication problems with the data link, refer to the corresponding data link manual for the operating status of each station Not doing so could result in erroneous output or erroneous operation o When connecting a peripheral device to the cpU module or connecting a personal computer or the like to the intelligent function module to exercise control (data change)on the running PLC configure up an interlock circuit in the sequence program to ensure that the whole system will always operate safely Also before exercising other control (program change, operating status change(status control)) on the running PLC, read the manual carefully and fully confirm safety Especially for the above control on the remote Plc from an external device, an immediate action may not be taken for PLc trouble due to a data communication fault In addition to configuring up the interlock circuit in the sequence program, corrective and other actions to be taken as a system for the occurrence of a data communication fault should be predetermined between the external device and PLC CPU △ CAUTION O Do not bunch the control wires or communication cables with the main circuit or power wires, or install them close to each other. They should be installed 100 mm(3.94 inch) or more from each other. Not doing so could result in noise that would cause erroneous operation o When controlling items like lamp load, heater or solenoid valve using an output module, large current(approximately ten times greater than that present in normal circumstances) may flow when the output is turned oFf to ON Take measures such as replacing the module with one having sufficient rated current A-2 A-2 [INSTALLATION PRECAUTIONSI △ CAUTION O Use the PLC in an environment that meets the general specifications contained in this manual Using this plc in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation and damage to or deterioration of the product O Hold down the module loading lever at the module bottom, and securely insert the module fixing latch into the fixing hole in the base unit Incorrect loading of the module can cause a malfunction, failure or drop When using the PLC in the environment of much vibration, tighten the module with a screw. Tighten the screw in the specified torque range. Undertightening can cause a drop, short circuit or malfunction. Overtightening can cause a drop, short circuit or malfunction due to damage to the screw or module wHen installing extension cables, be sure that the connectors of base unit are installed correctly. After installation, check them for looseness. Poor connections could cause an input or output failure O Securely load the memory card into the memory card loading connector. After loading, check for lifting Lifting can cause a malfunction due to a contact fault O Completely turn off the external power supply before loading or unloading the module. Not doing so could result in electric shock or damage to the product Note that online module change can be made when the QnPHCPU is used Note that there are restrictions on the modules that can be changed online and each module has a predetermined changing procedure For details, refer to the section of online module change in this manual O Do not directly touch the module's conductive parts or electronic components. Touching the conductive parts could cause an operation failure or give damage to the module TIRING PRECAUTIONS] DANGER O Completely turn off the external power supply when installing or placing wiring. Not completely turning off all power could result in electric shock or damage to the product O When turning on the power supply or operating the module after installation or wiring work, be sure that the module's terminal covers are correctly attached. Not attaching the terminal cover could result in electric shock A-3 A-3 TIRING PRECAUTIONSI △ CAUTION O Be sure to ground the fg terminals and LG terminals to the protective ground conductor. Not doing so could result in electric shock or erroneous operation O When wiring in the PLC, be sure that it is done correctly by checking the product's rated voltage and the terminal layout. Connecting a power supply that is different from the rating or incorrectly wiring the product could result in fire or damage O External connections shall be crimped or pressure welded with the specified tools, or correctly soldered. Imperfect connections could result in short circuit, fires, or erroneous operation O Tighten the terminal screws with the specified torque. If the terminal screws are loose, it could result in short circuits fire or erroneous operation tightening the terminal screws too far may cause damages to the screws and/or the module, resulting in fallout, short circuits, or malfunction O Be sure there are no foreign substances such as sawdust or wiring debris inside the module Such debris could cause fires, damage, or erroneous operation O The module has an ingress prevention label on its top to prevent foreign matter, such as wire offcuts, from entering the module during wiring Do not peel this label during wiring Before starting system operation, be sure to peel this label because of heat dissipation STARTUP AND MAINTENANCE PRECAUTIONST ◇ DANGER O Do not touch the terminals while power is on Doing so could cause shock or erroneous operation O Correctly connect the battery Also, do not charge, disassemble, heat, place in fire, short circuit, or solder the battery Mishandling of battery can cause overheating or cracks which could result in injury and fires O Switch all phases of the external power supply off when cleaning the module or retightening the terminal or module mounting screws not doing so could result in electric shock Undertightening of terminal screws can cause a short circuit or malfunction. Overtightening of screws can cause damages to the screws and/or the module, resulting in fallout, short circuits, or malfunction A-4 STARTUP AND MAINTENANCE PRECAUTIONS DANGER O The online operations conducted for the CPU module being operated, connecting the peripheral device(especially, when changing data or operation status), shall be conducted after the manual has been carefully read and a sufficient check of safety has been conducted Operation mistakes could cause damage or problems with of the module O Do not disassemble or modify the modules Doing so could cause trouble, erroneous operation, injury, or fire O Use any radio communication device such as a cellular phone or a PHs phone more than 25cm (9.85 inch) away from the Plc Not doing so can cause a malfunction O Switch all phases of the external power supply off before mounting or removing the module If you do not switch off the external power supply, it will cause failure or malfunction of the module Note that online module change can be made when the QnPHCPU is used Note that there are restrictions on the modules that can be changed online and each module has a predetermined changing procedure For details, refer to the section of online module change in this manual O Do not drop or give an impact to the battery installed in the module Otherwise the battery will be broken, possibly causing internal leakage of electrolyte Do not use but dispose of the battery if it has fallen or an impact is given to it DISPOSAL PRECAUTIONST △ CAUTION o When disposing of this product, treat it as industrial waste A-5 A-5 REVISIONS k The manual number is given on the bottom left of the back cover.
