All MicroSmart modules are manufactured under IDECs rigorous quality control system, but users must add a backup or failsafe provision to the control system using the MicroSmart in applications where heavy damage or personal injury may be caused in case the MicroSmart should fail. In this users manual, safety precautions are categorized in order of importance to Warning and Caution: Warning notices are used to emphasize that improper operation may cause Warning severe personal injury or death. Turn off the power to the MicroSmart before starting installation, removal, wiring, maintenance, and inspection of the MicroSmart. Failure to turn power off may cause electrical shocks or re hazard. Special expertise is required to install, wire, program, and operate the MicroSmart. People without such expertise must not use the MicroSmart. Install the MicroSmart according to the instructions described in this users manual. Improper installation will result in fall- ing, failure, or malfunction of the MicroSmart. Caution notices are used where inattention might cause personal injury or Caution damage to equipment. The MicroSmart is designed for installation in a cabinet. Do not install the MicroSmart outside a cabinet. Install the MicroSmart in environments described in this users manual. If the MicroSmart is used in places where the MicroSmart is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, and excessive shocks, then electrical shocks, re hazard, or malfunction will result. The environment for using the MicroSmart is Pollution degree 2. Use the MicroSmart in environments of pollution degree 2 (according to IEC 60664-1). Prevent the MicroSmart from falling while moving or transporting the MicroSmart, otherwise damage or malfunction of the MicroSmart will result. Prevent metal fragments and pieces of wire from dropping inside the MicroSmart housing. Put a cover on the MicroSmart modules during installation and wiring. Ingress of such fragments and chips may cause re hazard, damage, or malfunc- tion. Make sure of safety before starting and stopping the MicroSmart or when operating the MicroSmart to force outputs on or off. Incorrect operation on the MicroSmart may cause machine damage or accidents. Do not connect the ground wire directly to the MicroSmart. Connect a protective ground to the cabinet containing the MicroSmart using an M4 or larger screw. This is required when equipment containing the MicroSmart is destined for Europe. Do not disassemble, repair, or modify the MicroSmart modules. When disposing of the MicroSmart, do so as an industrial waste. FC5A EXPANSION RS232C COMMUNICATION MODULE USERS MANUAL PREFACE-1
