Safety Precautions(Read these precautions before use.)

Before installing, operating, maintenance or inspecting this product, thoroughly read and understand thismanual and the associated manuals. Also pay careful attention to handle the module properly and safety.

This manual classifies the safety precautions into two categories: and .

Depending on circumstances, procedures indicated by may also be linked to serious results.

In any case, it is important to follow the directions for usage.Store this manual in a safe place so that you can take it out and read it whenever necessary. Always forwardit to the end user.

1. DESIGN PRECAUTIONS

Indicates that incorrect handling may cause hazardous conditions, resulting indeath or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting inmedium or slight personal injury or physical damage.

Reference

• Provide a safety circuit on the outside of the PLC so that the whole system operates to ensure thesafety even when external power supply trouble or PLC failure occurs.Otherwise, malfunctions or output failures may result in an accident.

1) An emergency stop circuit, a protection circuit, an interlock circuit for opposite movements,such as normal and reverse rotations, and an interlock circuit for preventing damage to themachine at the upper and lower positioning limits should be configured on the outside of thePLC.

2) When the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, alloutputs are turned off. When an error that cannot be detected by the PLC CPU occurs in an

input/output control block, output control may be disabled.Design external circuits and mechanisms to ensure safe operations of the machine in such acase.

3) The output current of the 24V DC service power supply varies depending on the model and theabsence/presence of extension blocks. If overload is applied, the voltage automatically drops,inputs in the PLC are disabled, and all outputs are turned off.Design external circuits and mechanisms to ensure safe operations of the machine in such acase.

4) When some sort of error occurs in a relay, triac or transistor of the output unit, output may bekept on or off.For output signals that may lead to serious accidents, design external circuits and mechanismsto ensure safe operations of the machine in such cases.

Reference

• Do not bundle the control line together with the main circuit or power line. Do not lay the controlline near them.As a rule, lay the control line at least 100mm(3.94") or more away from the maincircuit or power line.

Noise may cause malfunctions.

• Install in a manner which prevents excessive force from being applied to the connectors for peripheral device connections.Failure to do so may result in wire breakage or failure of the PLC.

Reference

• Use the product in the environment within the generic specifications described in section 4.1 of thismanual.Never use the product in areas with dust, oily smoke, conductive dusts, corrosive gas (salt air, Cl 2,H2S, SO2 or NO2), flammable gas, vibration or impacts, or expose it to high temperature,condensation, or wind and rain.If the product is used in such a place described, electrical shock, fire, malfunctions, damage, or deterioration may be caused.

• Do not touch the conductive parts of the product directly, thus avoiding failure or malfunctions.

• Install the product securely using a DIN rail or mounting screws.

• Install the product on a flat surface.If the mounting surface is rough, undue force will be applied to the PC board, thereby causingnonconformities.

• Make sure to fix the function extension board with tapping screws for fixation.Tightening torque: 0.3 to 0.6 N•mContact failures may cause malfunctions.

• When drilling screw holes or wiring, cutting chips or wire chips should not enter ventilation slits.such an accident may cause fire, failures or malfunctions.

• Be sure to remove the dust proof sheet from the PLC's ventilation port when the installation work iscompleted. Failure to do so could cause fires, equipment failures, and malfunctions.

• Fit the extension cables, peripheral device connecting cables, input/output cables and batteryconnecting cable securely to the designated connectors.Contact failures may cause malfunctions.

• Fit the display module, memory cassette, and function extension board securely to the designatedconnectors.Contact failures may cause malfunctions.

• Before attaching or detaching the following devices, turn off power.Failure to do so may cause device failures or malfunctions.- Peripheral devices, display module , expansion boards and special adapters- Extension units/blocks and FX Series terminal block- Battery and memory cassette

• Connect the memory cassette securely to the prescribed connector. A poor connection can cause malfunctions.Installing the cassette in a raised or tilted posture can also cause malfunctions.

3. WIRING PRECAUTIONS

Reference

• Connect the AC power supply wiring to the dedicated terminals described in this manual.If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, thePLC will be burnt out.

• Cut off all phases of the power source externally before installation or wiring work in order to avoidelectric shock or damage of product.

• Make sure to attach the terminal cover offered as an accessory to the product before turning onthe power or starting the operation after installation or wiring work.Failure to do so may cause electric shock.

122145148151162203221260283405

Reference

• Do not supply power to the [24+] and [24V] terminals (24V DC service power supply) in the main

unit and extension units from the outside.Such power supply may cause damages to the product.

• Perform class D grounding (grounding resistance: 100 Ω or less) to the grounding terminal in the

main unit and extension units with a 2mm2 or thicker wire.Do not connect the grounding terminal at the same point as a heavy electrical system (refer toSection 9.4).

• Connect the DC power supply wiring to the dedicated terminals described in this manual.If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, thePLC will be burnt out.

• Do not wire vacant terminals externally.Doing so may damage the product.

• When drilling screw holes or wiring, cutting chips or wire chips should not enter ventilation slits.such an accident may cause fire, failures or malfunctions.

• Perform wiring properly to the FX0N/FX2N/FX3U Series extension equipment of the terminal blocktype in accordance with the following precautions.Failure to do so may cause electric shock, short-circuit, wire breakage, or damages to the product.- The disposal size of the cable end should follow the dimensions described in this manual.- Tightening torque should be between 0.5 to 0.8 N•m.

• Observe the following items to wire the lines to the European terminal board. Ignorance of thefollowing items may cause electric shock, short circuit, disconnection, or damage of the product.- The disposal size of the cable end should follow the dimensions described in this manual.- Tightening torque should be between 0.22 to 0.25 N•m.- Twist the end of strand wire and make sure there is no loose wires.- Do not solder-plate the electric wire ends.- Do not connect electric wires of unspecified size or beyond the specified number of electric

wires.- Fix the electric wires so that the terminal block and connected parts of electric wires are not

directly stressed.
