Also pay careful attention to safety and handle the module properly These precautions apply only to Mitsubishi equipment. Refer to the CPU module user's manual for a description of the Pc system safety precautions These SAFETY PRECaUTIoNS classify the safety precautions into two categories: "DANGER"and CAUTION ◇ DANGER Procedures which may lead to a dangerous condition and cause death or serious injury if not carried out properly. △ CAUTION Procedures which may lead to a dangerous condition and cause superficial to medium injury, or physical damage only, if not carried out properly. Depending on circumstances, procedures indicated by A CAUTION may also be linked to serious results In any case, it is important to follow the directions for usage Store this manual in a safe place so that you can take it out and read it whenever necessary. Always forward it to the end user DESIGN PRECAUTIONS] ◇ DANGER When performing the control of the PC in operation ( especially changing data, program, and operation status(status control)) by connecting a personal computer, etc to the special function module configure an interlock circuit in a sequence program so the safety of the overall system Is always maintained Especially, when this control is performed to a remote PC from an extemal device, troubles that have occurred on the Pc side may not be able to immediately be handled if there is a data communication error define a troubleshooting agreement between external devices and the pc cPu for data communication error occurrences. as well as construct an interlock circuit in the sequence program [DESIGN PRECAUTIONS] △ CAUTION 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 100mm ( 3.9 inch)or more from each other Not doing so could result in noise that would cause erroneous operation INSTALLATION PRECAUTIONS △ CAUTION Use the Pc in an environment that meets the general specifications contained in this manual. Using this Pc 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. Switch all phases of the extenal power supply off when installing or placing wiring. Not doing so could result in electric shock or damage to the product Insert the tabs at the bottom of the module into the mounting holes in the base unit. Then tighten the module installation screws with specified torque. If the module is not properly installed, it may result in malfunction breakdowns, or the module may fall off Tighten the screw within the range of specified torque If the screws are loose, it may result in fallout, short circuits, or malfunction Tightening the screws too far may cause damages to the screws and/or the module, resulting in a fallout, short circuits, or malfunction Do not directly touch the module' s conductive parts or electronic components. doing so could cause malfunction or trouble in the module Perform correct pressure-displacement, crimp-contact or soldering for wire connections using the tools specified by the manufactures. Attach connectors to the module securely WIRING PRECAUTIONS] △ CAUTION Be sure to secure communication cables in ducts or fix them with cramps Failure to do so may cause a damage to the module or cables due to dangling, shifting or inadvertent handling of cables, or misoperation due to bad cable connection Before connecting the cables, check the type of interface to be connected Connection, or erroneous wiring, to the wrong interface may damage the module and external devices Tighten the terminal screw within the range of specified torque If the screws are loose, it may result in short circuits or malfunction Tightening the screws too far may cause damages to the screws and/or the module, resulting in a fallout, short circuits, or malfunction Do not grab on the cable when removing the communication cable connected to the module When removing the cable with a connector, hold the connector on the side that is connected to the module When removing the cable without a connector, first loosen the screws on the part that is connected to the module Pulling the cable that is still connected to the module may cause a damage to the module or cable or misoperation due to bad cable contacts 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 STARTING AND MAINTENANCE PRECAUTIONS] ◇ DANGER Do not touch the connector while the power is on. doing so could cause erroneous operation. Switch all phases of the external power supply off before cleaning or re- tightening screws. If you do not switch off the external power supply, it will cause failure or malfunction of the module If the screws are loose it may result in fallout, short circuits or malfunction Tightening the screws too far may cause damages to the screws and/or the module, resulting in a fallout, short circuits, or malfunction STARTING AND MAINTENANCE PRECAUTIONSI △ CAUTION Do not disassemble or modify the modules. Doing so could cause trouble, erroneous operation, injury, or fire 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 TOPERATING PRECAUTIONSI ◇ DANGER Do not write data into the system area" of the buffer memory of special function modules. Also, do not output the" prohibited to use" signal as the output signal to a special function module from the PC CPu Writing data into the"system area"or outputting a signal for" prohibited to use"may cause system malfunctions in the Pc △ CAUTION Before performing the control of the Pc in operation(especially changing data, program, and operation status (status control)) by connecting a personal computer, etc to the special function module, read the manual carefully and confirm if the overall safety is maintained Failure to perfom correct operations to change data, program, or the status may result in system malfunction, machine damage, or an accident When using the module while values, such as buffer memory set values, are registered in the EEPROM, do not turn off the power supply for the module loading station nor reset the PC CPU If the power supply for the module loading station is truned off or the pc CPU is reset while any values are registered, the data contents in the EEProM become inconsistent and as a result the values must be set again in the buffer memory, etc and reregistered to the EEPROM. also this may cause failure and malfunction of the module [DISPOSAL PRECAUTIONST △ CAUTION When disposing of this product, treat it as industrial waste.
