Safety Precautions

(Read these precautions before use.)

Before installation, operation, maintenance or inspection of this product, thoroughly read through and understand
this manual and all of the associated manuals. Also, take care to handle the module properly and safely.

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

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

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

Depending on the circumstances, procedures indicated by may also cause severe injury.
It is important to follow all precautions for personal safety.
Store this manual in a safe place so that it can be taken out and read whenever necessary. Always forward it
to the end user.

1. DESIGN PRECAUTIONS

• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during
external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.

1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for

opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the
equipment at the upper and lower positioning limits).

2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all

outputs are turned off. Also, when an error that cannot be detected by the PLC CPU occurs in an input/output
control block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

3) Note that the output current of the service power supply for sensors varies depending on the model and the

absence/presence of extension blocks. If an overload occurs, the voltage automatically drops, inputs in the
PLC are disabled, and all outputs are turned off.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

Note that when an error occurs in a relay, triac or transistor output device, the output could be held either on or off.

4)

For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to
ensure safe machinery operation in such a case.

• Do not bundle the control line together with or lay it close to the main circuit or power line. As a guideline, lay the
control line at least 100mm (3.94") or more away from the main circuit or power line.
Noise may cause malfunctions.

• Install module so that excessive force will not be applied to the built-in programming port, power connectors, I/O
connectors, communication connectors, or communication cables.
Failure to do so may result in wire damage/breakage or PLC failure.

(1)

Safety Precautions

(Read these precautions before use.)

2. WIRING PRECAUTIONS

• Make sure to cut off all phases of the power supply externally before attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.

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

• Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents due
to abnormal data written to the PLC under the influence of noise:

1) Do not bundle the main circuit line together with or lay it close to the main circuit, high-voltage line or load line.

Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the control line
at least 100mm (3.94") or more away from the main circuit or high-voltage line.

2) Ground the shield wire or shield of the shielded cable at one point on the PLC. However, do not use grounding

with heavy electrical systems.

• Make sure to properly wire the FX
precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or damage to the product.

- The disposal size of the cable end should follow the dimensions described in this manual.

- Tightening torque should follow the specifications in this manual.

• Make sure to properly wire to the European terminal board in accordance with the following precautions.
Failure to do so may cause electric shock, a short-circuit, wire breakage, or damage to the product.

- The disposal size of the cable end should follow the dimensions described in this manual.

- Tightening torque should be follow the specifications in this manual.

- Twist the end of strand wire and make sure that there are no loose wires.

- Do not solder-plate the electric wire ends.

- Do not connect more than the specified number of wires or electric wires of unspecified size.

- Affix the electric wires so that neither the terminal block nor the connected parts are directly stressed.

0N/FX2N Series extension equipment in accordance with the following

3. STARTUP AND MAINTENANCE PRECAUTIONS

• Do not touch any terminal while the PLC's power is on.
Doing so may cause electric shock or malfunctions.

• Before cleaning or retightening terminals, cut off all phases of the power supply externally.
Failure to do so may cause electric shock.

• Before modifying or disrupting the program in operation or running the PLC, carefully read through this manual
and the associated manuals and ensure the safety of the operation.
An operation error may damage the machinery or cause accidents.

• Do not change the program in the PLC from two or more peripheral equipment devices at the same time.
(i.e. from a programming tool and a GOT)
Doing so may cause destruction or malfunction of the PLC program.

• Do not disassemble or modify the PLC.
Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric distributor.

• Turn off the power to the PLC before connecting or disconnecting any extension cable.
Failure to do so may cause equipment failures or malfunctions.

• Turn of the power to the PLC before attaching or detaching the peripheral devices, expansion boards, special
adapters, and expansion memory cassette.
Failure to do so may cause equipment failures or malfunctions.
