• SAFETY PRECAUTIONS •

(Read these precautions before using this product.)

Before using this product, please read this manual and the relevant manuals carefully and pay full

attention to safety to handle the product correctly.

The precautions given in this manual are concerned with this product only. For the safety precautions of

the programmable controller system, refer to the user’s manual for the CPU module used.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

Indicates that incorrect handling may cause hazardous conditions,

resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions,

resulting in minor or moderate injury or property damage.

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to

serious consequences.

Observe the precautions of both levels because they are important for personal and system safety.

Make sure that the end users read this manual and then keep the manual in a safe place for future

reference.

[Design Precautions]

WARNING

• When the network develops a communication error, the station with the communication error will

enter into the following status.

Check the communication status information and configure an interlock circuit in the sequence

program to ensure that the entire system will operate safely. Failure to do so may result in an

accident due to an incorrect output or malfunction.

(1) The remote master station will hold the data from before the communication error.

(2) The remote I/O station turns off all outputs. The output module of the remote I/O station can

clear/hold the output status at the time of error by using the remote I/O module parameters.

As the parameters are set to "clear" by default, the output module turns off the outputs at the

time of error. If it is required to hold the output in order to operate the system safely, set the

parameters to "hold".

WARNING

CAUTION

A - 2 A - 2

[Design Precautions]

WARNING

• When connecting a peripheral with the programmable controller CPU or connecting a personal

computer with an intelligent function module to modify data of a running programmable

controller, configure an interlock circuit in the sequence program to ensure that the entire

system will always operate safely. For other forms of control (such as program modification or

operating status change) of a running programmable controller, read the relevant manuals

carefully and ensure that the operation is safe before proceeding. Especially, when a remote

programmable controller is controlled by an external device, immediate action cannot be taken if

a problem occurs in the programmable controller due to a communication failure. To prevent

this, configure an interlock circuit in the sequence program, and determine corrective actions to

be taken between the external device and CPU module in case of a communication failure.

• If a communication cable is disconnected, the network may be unstable, resulting in a

communication failure of multiple stations. Configure an interlock circuit in the program to ensure

that the entire system will always operate safely even if communications fail. Failure to do so

may result in an accident due to an incorrect output or malfunction.

CAUTION

• Do not install the control lines or communication cables together with the main circuit lines or

power cables. Keep a distance of 100mm or more between them. Failure to do so may result in

malfunction due to noise.

• Reset the CPU module or remote I/O module after changing its parameters. Failure to do so

may cause malfunction because the previous parameter settings remain in the module.

[Installation Precautions]

CAUTION

• Use the programmable controller in an environment that meets the general specifications in the

user’s manual for the CPU module used. Failure to do so may result in electric shock, fire,

malfunction, or damage to or deterioration of the product.

• To mount the module, while pressing the module mounting lever located in the lower part of the

module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the

module until it snaps into place. Incorrect mounting may cause malfunction, failure or drop of the

module. When using the programmable controller in an environment of frequent vibrations, fix

the module with a screw.

• Tighten the screws within the specified torque range. Undertightening can cause drop of the

screw, short circuit, or malfunction. Overtightening can damage the screw and/or module,

resulting in drop, short circuit, or malfunction

• Shut off the external power supply (all phases) used in the system before mounting/removing a

module or connecting/disconnecting a connector. Failure to do so may result in damage to the

product. Modules can be replaced online on a remote I/O station where a remote I/O module

with function version D or later is used. Note that there are restrictions on the modules that can

be replaced online, and each module has its predetermined replacement procedure. For details,

refer to the relevant section in this manual.

A - 3 A - 3

[Installation Precautions]

CAUTION

• Do not directly touch any conductive parts and electronic components of the module.

Doing so can cause malfunction or failure of the module.

[Wiring Precautions]

WARNING

• Shut off the external power supply (all phases) used in the system before installation and wiring.

Failure to do so may result in electric shock or damage to the product.

[Wiring Precautions]

CAUTION

• Individually ground the FG terminal of the programmable controller with a ground resistance of

100Ω or less.

Failure to do so may result in electric shock or malfunction.

• Check the rated voltage and terminal layout before wiring to the module, and connect the cables

correctly. Connecting a power supply with a different voltage rating or incorrect wiring may

cause a fire or failure.

• Connectors for external devices and coaxial cables must be crimped or pressed with the tool

specified by the manufacturer, or must be correctly soldered. Incomplete connections may

cause short circuit, fire, or malfunction.

• Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be

pulled, resulting in damage to the module or cables or malfunction due to poor contact.

• Tighten the terminal screws within the specified torque range. Undertightening can cause short

circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in

drop, short circuit, or malfunction.

• When disconnecting the cable from the module, do not pull the cable by the cable part. For the

cable with connector, hold the connector part of the cable. For the cable connected to the

terminal block, loosen the terminal screw. Pulling the cable connected to the module may result

in malfunction or damage to the module or cable.

• Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter

can cause a fire, failure, or malfunction.

• A protective film is attached to the top of the module to prevent foreign matter, such as wire

chips, from entering the module during wiring.

Do not remove the film during wiring.

Remove it for heat dissipation before system operation.

• Mitsubishi Electric programmable controllers must be installed in control panels. Connect the

main power supply to the power supply module in the control panel through a relay terminal

block. Wiring and replacement of a power supply module must be performed by qualified

maintenance personnel with knowledge of protection against electric shock. For wiring methods,

refer to the QCPU User's Manual (Hardware Design, Maintenance and Inspection).
