B-1722(4) FC6A SERIES Users ManualSAFETY PRECAUTIONS Read theFC6A Series MICROSmart Users Manua to ensure correct operation before starting installation, wiring, operation, maintenance, and inspection of the FC6A Series MICROSmart. All FC6A Series MICROSmart modules are manufactured under IDECs rigorous quality control system, but users must add a backup or failsafe provision to the control system when using the FC6A Series MICROSmart in applications where heavy damage or personal injury may be caused, in case the FC6A Series MICROSmart should fail. In this manual, safety precautions are categorized in order of importance: Warning Warning notices are used to emphasize that improper operation may cause severe personal injury or death. The FC6A Series MICROSmart is not designed for use in applications requiring a high degree of reliability and safety. The FC6A Series MICROSmart should not be used for such applications. When using the FC6A Series MICROSmart in applications (not described above) that require a high degree of reliability in terms of functionality and precision, appropriate measures such as failsafe mechanisms and redundant mechanisms must be taken for the system containing the FC6A Series MICROSmart. The following are specific examples. Emergency stop and interlocking circuits must be configured outside the FC6A Series MICROSmart. If relays or transistors in the FC6A Series MICROSmart output circuits should fail, outputs may remain at on or off state. For output signals which may cause serious accidents, configure monitor circuits outside the FC6A Series MICROSmart. The FC6A Series MICROSmart self-diagnostic function may detect internal circuit or program errors, stop programs, and turn outputs off. Configure circuits so that the system containing the FC6A Series MICROSmart is not jeopardized when outputs turn off. Turn off power to the FC6A Series MICROSmart before installation, removal, wiring, maintenance, and inspection of the FC6A Series MICROSmart. Failure to turn power off may cause electrical shocks or fire hazard. Special expertise is required to install, wire, program, and operate the FC6A Series MICROSmart. People without such expertise must not use the FC6A Series MICROSmart. Install the FC6A Series MICROSmart according to the instructions described in theFC6A Series MICROSmart Users Manua. Improper installation will result in falling, failure, or malfunction of the FC6A Series MICROSmart. Caution notices are used where inattention might cause personal injury or damage to equipment. Caution The FC6A Series MICROSmart is designed for installation in a cabinet. Do not install the FC6A Series MICROSmart outside a cabinet. Install the FC6A Series MICROSmart in environments described in theFC6A Series MICROSmart Users Manua. If the FC6A Series MICROSmart is used in places where the FC6A Series MICROSmart is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, or excessive shocks, then electrical shocks, fire hazard, or malfunction will result. The environment for using the FC6A Series MICROSmart isPollution degree 2 Use the FC6A Series MICROSmart in environments of pollution degree 2 (according to IEC 60664-1). Prevent the FC6A Series MICROSmart from falling while moving or transporting the FC6A Series MICROSmart, otherwise damage or malfunction of the FC6A Series MICROSmart will result. Wiring must use lead sizes that are appropriate for the applied voltage and current. Terminal screws must be tightened with the prescribed tightening torque. Prevent metal fragments and pieces of wire from dropping inside the FC6A Series MICROSmart housing. Put a cover on the FC6A Series MICROSmart modules during installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction. Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard. Use an IEC 60127-approved fuse on the power line outside the FC6A Series MICROSmart. This is required when equipment containing the FC6A Series MICROSmart is destined for Europe. Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the FC6A Series MICROSmart is destined for Europe. Use an EU-approved circuit breaker. This is required when equipment containing the FC6A Series MICROSmart is destined for Europe. Make sure of safety before starting and stopping the FC6A Series MICROSmart or when operating the FC6A Series MICROSmart to force outputs on or off. Incorrect operation of the FC6A Series MICROSmart may cause machine damage or accidents. Do not connect the ground wire directly to the FC6A Series MICROSmart. Connect a protective ground to the cabinet containing the FC6A Series MICROSmart using an M4 or larger screw. This is required when equipment containing the FC6A Series MICROSmart is destined for Europe. Do not disassemble, repair, or modify the FC6A Series MICROSmart modules. The FC6A Series MICROSmart contains electronic parts and batteries. When disposing of the FC6A Series MICROSmart, do so in accordance with national and local regulations.
