SAFETY PRECAUTIONS
•Read the "FC6A Series MicroSmart All-in-One Type Communication Manual" 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 IDEC’s 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 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 the "FC6A Series MicroSmart All-in-One Type User’s Manual".
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.
•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 the "FC6A Series MicroSmart All-in-One Type User’s Manual". 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 is "Pollution 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.

1: GENERAL INFORMATION
Introduction
This chapter describes an overview of the FC6A Series MicroSmart, which is equipped with a communication interface.
Description
The FC6A Series MicroSmart can perform RS232C and RS485 communication using serial port 1. The communication ports can be
expanded by using communication cartridges to allow for multiple instances of RS232C and RS485 communication. The Ethernet
port is standard equipment to enable communication using Ethernet. Also, the Ethernet port can be expanded by using an HMI
module. The CAN J1939 All-in-One Type is equipped with a CAN port to enable J1939 communication.
