Procedures which may lead to a dangerous CAUTION condition and cause superficial to medium injury, or physical damage only, if not carried out properly. Depending on circumstances, procedures indicated by may CAUTION 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 controlling (changing data, program or operation status (status control) in particular) a PC while it is running via a device such as a personal computer connected to the special function module, configure an interlock circuit in the sequence program so that the safety of the overall system is always maintained. Especially, when performing the above control for a remote PC from an external device, troubles occurring on the PC side due to data communication error may not be handled immediately. Determine error handling methods between the external device and the PC CPU for when data communication errors occur, in addition to configuring an interlock circuit in the sequence program. [DESIGN PRECAUTIONS] CAUTION • When laying AUI cable (transceiver cable)/coaxial cable, do not bundle with or place near main circuit or power line. Keep them at least 100 mm (3.94 in.) away from such cables. Noise may cause erroneous operation. [INSTALLATION PRECAUTIONS] CAUTION • Use the PC in the environment given in the general specifications section of this manual. Using the PC outside the range of the general specifications may result in electric shock, fire, or erroneous operation or may damage or degrade the product. • Make sure to switch all phases of the external power supply off when installing or placing wiring. If you do not switch off the external power supply, it will cause electric shock or damage to the product. • Make sure to switch all phases of the external power supply off before mounting the module. If you do not switch off the external power supply, it will cause electric shock or damage to the product. • Insert the tabs at the bottom of the module into the holes in the base unit before installing the module. (The Q2AS series module shall be fastened by screws in the base unit at the specified torque.) Improper installation may cause erroneous operation, accidents, or the module to fall out. • Tighten the screw within the range of specified torque.

Tightening the screws to far may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction. • Do not touch the electronic parts or the unit conducting area. It may cause erroneous operation or failure. • 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 • Do not connect the AUI cable when the module installation station's power is turned on. • Make sure to secure communication cable and power supply cable connected to the module is stored in the conduct or fixed with cramps. Failure to do so may cause a malfunction or damage to the module or cables due to dangling or inadvertent handling of cables. • Tighten the screw within the range of specified torque. If the screws are loose, it may result in short circuits or malfunction. Tightening the screws to far may cause damage to the screw and/or the module, resulting in 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. Pulling the cable that is still connected to the module may cause a malfunction or damage to the module or cable. • Be sure that cuttings, wire chips, or other foreign matter do not enter the module. Foreign matter may start a fire or cause an accident or erroneous operation. [STARTING AND MAINTENANCE PRECAUTIONS] DANGER • Do not touch live terminals. It may cause erroneous operation. • Make sure to switch all phases of the external power supply off before cleaning or retightening terminal screw. If you do not switch off the external power supply, it will cause a damage to a module or malfunction. If the screws are loose, it may result in fallout, short circuits or malfunction. Tightening screws too far may cause damages to the screws and/or the module, resulting in fallout, short circuits or malfunction. [STARTING AND MAINTENANCE PRECAUTIONS] CAUTION • Do not disassemble or rebuild the module. It may cause accidents, erroneous operation, injury, or fire. • Turn off the power before mounting and dismounting the module. Mounting or dismounting the module while the power is on may damage the module or cause erroneous operation. [PRECAUTIONS WHILE OPERATING] DANGER • Do not write data in the "system area" in the buffer memory of the special function module. Also, of the output signals directed to the special function module from the PC CPU, do not output (switch on) the signals that are "use-prohibited." If data is written to the "system area" or output is performed with respect to a "use-prohibited" signal, it may result in the malfunctioning of the PC system. CAUTION When controlling (changing data, program or operation status (status • control) in particular) a PC while it is running via a device such as a personal computer connected to the special function module, read the manual carefully and conform if the overall safety is maintained. Failure to perform correct operations to change data, program, or the status may result in system malfunction, machine damage or an accident. When performing remote RUN/STOP for the PC CPU on the station • loading this module (or the present station), it is recommended to read the manual thoroughly and use the function stated as "data communication when PC CPU is stopped." If remote RUN/STOP is performed without using the "data communication when PC CPU is stopped" function, the communication line will be disconnected (by the close processing), since the output signal to this module from the PC CPU turns off. Therefore, all data communication will be disabled thereafter, including the remote RUN/STOP control of the PC CPU from other nodes.
