INSTRUCTION SHEETFC6A Series
Communication moduleThis sheet provides brief operating instructions of the MICROSmart programmable controller.
For details, see the FC6A Series MICROSmart User’s Manual.

Safety Precautions
Special expertise is required to use the MICROSmart.
● Read this instruction sheet and the user's manual to make sure of correct operation before starting
installation, wiring, operation, maintenance, and inspection of the MICROSmart.
Keep this instruction sheet where it can be accessed by the end user.
● All MICROSmart modules are manufactured under IDEC's rigorous quality control system, but users
must add backup or failsafe provisions to control systems use the MICROSmart in applications where
heavy damage or personal injury may be caused if the MICROSmart should fail.
● Install the MICROSmart according to the instructions described in this instruction sheet and the user's
manual. Improper installation will result in falling, failure, or malfunction of the MICROSmart.
● Make sure that the operating conditions are as described in the user’s manual. If you are uncertain
about the specifications, contact IDEC before using the MICROSmart.
● In this instruction sheet, safety precautions are categorized in order of importance from Warning andCaution:

For details about mounting and removing modules, see the user’s manual.

Applicable model
FC6A Series MICROSmart CPU module[Mounting on DIN Rail]Use a 35-mm-wide DIN rail and BNL6 mounting clips to secure the modules.

2* See the user’s manual for more details on the product specifications.

Parts Description(1) Pull out the DIN Rail HookPort 1(3) Press the modules
towards the DIN railRS485(4) Push in the DIN Rail HookRS232C[Direct Mounting on Panel Surface]
Pull out the DIN rail Hook on the back of the module and insert the direct mounting Hook
(FC6A-PSP2PN05) into the slot.
Attach the module to the mounting plate using the screw holes.
Attach the module to the mounting plate using M4 tapping screws, as shown below, or make 5 to
6mm mounting holes and secure the module using M4 pan head screws. Always give sufficientconsideration to operability, ease-of-maintenance, and environmental resistance when deciding on
the mounting position.

Use a proper cable for wiring the terminals.
Crimp the ferrules to the wire cable.
Before wiring, read the user’s manual for the remote device
connected to the modules.
Use the shielded cable and connect the shields of the cableto ground to suppress the influence of noises.
If the communication quality is unstable, insert appropriate
termination resistors matched to the characteristic
impedance of the cabole.
Over 1/2W resistors are recommended for the terminal resistor.

If the MICROSmart is used in places where it is subjected to high-temperature, high-humidity,condensation, corrosive gases, excessive vibrations, or excessive shocks it will result in electricalshocks, fire hazard, or malfunction.
● The environment rating for using the MICROSmart is “Pollution degree 2.”● Prevent metal fragments and pieces of wire from dropping inside the MICROSmart housing.
Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.
● Use wires of a proper size to meet voltage and current requirements. Tighten terminal screws to theproper tightening torque of 0.28 N-m.
● Use an IEC60127-approved fuse on the power line and output circuit to meet voltage and current
requirements.(Recommended fuse: Littelfuse 5×20mm slow-blow type 218000 series/Type T)
This is required when exporting equipment containing MICROSmart to Europe.
● Use an EU-approved circuit breaker. This is required when exporting equipment containing
MICROSmart to Europe.
● If relays or transistors in the MICROSmart output modules should fail, outputs may remain on or off.
For output signals which may cause heavy accidents, provide a monitor circuit outside of theMICROSmart.
● Do not disassemble, repair, or modify MICROSmart modules.
