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 whereheavy 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'smanual. 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:
Warning notices are used to emphasize that improper operation may cause severe personal injury or death.
Caution notices are used where inattention might cause personal injury or damage to equipment.

● Turn off the power to the MICROSmart before starting installation, removal, wiring, maintenance, orinspection on the MICROSmart. Failure to turn off the power may cause damage, electrical shocks orfire hazard.
● Emergency stop and interlocking circuits must be configured outside the MICROSmart. If such a circuit
is configured inside the MICROSmart, failure of the MICROSmart may cause disorder of the controlsystem, damage, or accidents.
● SUITABLE FOR USE IN CLASS 1, DIVISION 2, GROUPS A,B,C AND D HAZARDOUS
LOCATIONS, OR NONHAZARDOUS LOCATIONS ONLY.
● Cet appareil convient uniquement à ľemploi dans des zones dangereuses de classe 1,groupes A,B,C et D; ou dans des zones non dangereuses.
● WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT WHILE THE CIRCUITIS LIVE OR UNLESS THE AREA IS KNOWN TO BE FREE OF IGNITABLE CONCENTRATIONS.
● Avertissement: risque d'explosion. Ne pas débrancher ľappareil tant que le circuit est sous tension,ou à moins ďêtre certain que lieu ďutilisation soit exempt de concentrations inflammables.
● THIS EQUIOMENT IS AN OPEN -TYPE DEVICE MEANT TO BE INSTALLED IN AN ENCLOSURESUITABLE FOR THE ENVIRONMENT THAT IS ONLY ACCESSIBLE WIHT THE USE OF A TOOLOR KEY.
● Cet appareil doit être installé dans un boîtier qui est adapté à ľenvironnement ďutilisation etuniquement accessible avec un outil ďouverture ou une clé.

If there is an interruption of the power supply (power off) for the expansion interface
module during operation, the outputs for all of the expansion modules (both the basicexpansion side and the expansion interface side) during the power interruption will beoff (they are automatically reset and the I/O is turned off). When the power recovers
from the interruption, the expansion modules (both the basic expansion side and theexpansion interface side) are restored to their original statuses.

If the expansion interface module main power supply is on and the CPU module main
power supply is off, the expansion modules on the expansion interface side are set tothe reset status. Please note that during the reset status, the analog module and PID
module LED indicators are on. This is not a malfunction.

1. When connecting an Expansion interface module, remove the expansion connector
sticker from the I/O module.
2. Place the I/O module and Expansion interface module side by side.
Put the expansion connectors together for easy alignment.
3. With the expansion connectors aligned correctly and the eject button in the down
position, press the I/O module and Expansion interface module together until thelatches click to attach the modules together firmly.
If the eject button is in the up position, push down the button to engage the latches.

7 maximum● Install the MICROSmart in environments as described in the user's manual. If the MICROSmart is usedin places where it is subjected to high-temperature, high-humidity, condensation, corrosive gases,
excessive vibrations, or excessive shocks itwill result in electrical shocks, 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. Ingressof 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 0.51 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.

[Direct Mounting on Panel Surface]
Pull out the DIN Rail hook on the back of the module and insert the direct mounting
hook (FC6A-PSP1PN05) 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 sufficient consideration to operability, ease-of-maintenance, and environmental
resistance when deciding on the mounting position.
