NOTE
○Follow the instructions given below when designing, selecting and handling the product.
● The instructions on design and selection
(installation, wiring, environment, adjustment, operation, maintenance, etc.)
described below must also be followed.
∗Product specifications
•When conformity to UL is required, the SI unit should be used with a UL1310 Class 2 power supply.
•The SI unit is a approved product only if they have a
•Use the specified voltage.
mark on the body.
Otherwise failure or malfunction can result.
•Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
•Do not remove any nameplates or labels.
This can lead to incorrect maintenance, or misreading of the operation manual, which could cause damage or malfunction to the product.
It may also result in non-conformity to safety standards.
● Product handling
∗Installation
•Do not drop, hit or apply excessive shock to the fieldbus system.
Otherwise damage to the product can result, causing malfunction.
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws may be broken.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
∗Wiring
•Avoid repeatedly bending or stretching the cables, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause breakage of the cable.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the fieldbus system and/or I/O device can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the fieldbus system and/or I/O device can malfunction due to interference of noise and surge voltage from power and high voltage cables to the signal line.
Route the wires (piping) of the fieldbus system and/or I/O device separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess voltage or current being applied to the product, causing damage.
•Take appropriate measures against noise, such as using a noise filter, when the fieldbus system is incorporated into equipment.
Otherwise noise can cause malfunction.

No.EX##-OMB0014-E
∗Environment
•Select the proper type of protection according to the environment of operation.
In case of IP20, avoid use in the place where water and oil scatter.
•Do not use the product in an environment where corrosive gases or fluids could be splashed.
Otherwise damage to the product and malfunction can result.
•Do not use in an area where surges are generated.
If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction furnace, motor, etc.) close to the fieldbus system, this may cause deterioration or breakage of the internal circuit of the fieldbus system. Avoid sources of surge generation and crossed lines.
•When a surge-generating load such as a relay or solenoid is driven directly, use an fieldbus system with a built-in surge absorbing element.
Direct drive of a load generating surge voltage can damage the fieldbus system.
•The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes in the system.
•Prevent foreign matter such as remnant of wires from entering the fieldbus system to avoid failure and malfunction.
•Mount the product in a place that is not exposed to vibration or impact.
Otherwise failure or malfunction can result.
•Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.

Communication wiring
The connection between a CC-Link-dedicated cable and an SI unit communication terminal for CC-Link is shown below.
(1) Be sure to connect each signal line to its dedicated terminal. (Refer to Fig. 1)
Tighten the screws securely with a torque of 0.5 to 0.6 Nm.
The terminal screw is an M3 cross head screw.
Fig. 1
(2) Be sure to connect a terminating resistor between “DA” and “DB” at both ends of the CC-Link system.
(Refer to Fig. 2)
(3) The appropriate terminating resistor varies depending on the CC-Link cable used.
(Refer to the table and Fig. 3 below.)

(4) The CC-Link-dedicated cable’s shield wire (SLD) should be connected to the “FG” terminal of the SI unit.
For the EX12#-SMJ1, the "SLD terminal" and "FG terminal" are common.
Therefore, connect 3 wires to the "FG Terminal" as shown in Fig. 4.
Fig. 4: Wiring to the FG terminal on the SI unit
When connecting 3 wires to the “FG terminal”, crimp 2 wires together into one crimped terminal as shown in Fig. 5. Use another crimped terminal for other wires.
After crimping, connect wires so that the back of the two crimped terminals face each other.

○Troubleshooting
Applicable model: EX12#-SMJ1
If an operation failure of the product occurs, please confirm the cause of the failure from the following table.
If a cause applicable to the failure cannot be identified and normal operation can be recovered by replacement with a new product, this indicates that the product itself was faulty.
Problems with the product may be due to the operating environment (network construction etc). Please consult SMC.
If the cause of the problem cannot be found and the SI unit is not faulty, then inconsistencies with parameter settings or the network construction at the master station is possible.
