SAFETY INSTRUCTIONS

(Always read these instructions before using this equipment.)

Before using this product, please read this manual and the relevant manuals introduced in this manual

carefully and pay full attention to safety to handle the product correctly.

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

programmable controller system, please read the CPU module user's manual.

In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".

!DANGER

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 medium or slight personal injury or physical damage.

Note that the !CAUTION level may lead to a serious consequence according to the circumstances.

Always follow the instructions of both levels because they are important to personal safety.

Please save this manual to make it accessible when required and always forward it to the end user.

[Design Instructions]

!DANGER

If a communication error occurs in the data link, the following will occur in the station having the

communication error.

Use the communication status information, and configure an interlock circuit in the sequence

program so that the system will operate safely.

Incorrect outputs and incorrect operations can lead to accidents.

(1) All points of the general-purpose input from this module will turn OFF.

(2) All points of the general-purpose output from this module will turn OFF.

The input/output may turn ON or OFF depending on the module trouble.

Provide a circuit that externally monitors input/output signals that could lead to serious trouble.

A - 2

!CAUTION

Do not bind the control wire or communication cable with the main circuit or power wire, or

place the control wire near these.

Separate by at least 100mm or more.

Failure to observe this could lead to malfunctions caused by noise.

Always connect the master module and CC-Link dedicated cable at the data link terminal block.

If the data link terminal block and general-purpose input/output terminal block are incorrectly

inserted, module trouble could occur.

[Mounting Instructions]

!CAUTION

Use this module within the general specification environment described in the manual.

Use in an environment outside the general specification range could lead to electric shocks,

fires, malfunctioning, product damage or deterioration.

Always connect the crimp, press-fit or solder the connector wire connections with the maker-

designated tools, and securely connect the connector to the module.

An incomplete connection could lead to short-circuits or malfunctioning.

Do not directly touch the conductive section of the module.

Failure to observe this could lead to module malfunctioning or trouble.

Securely fix the module with the DIN rail or installation screw. Tighten the installation screw

within the designated torque range.

A loose screw could lead to dropping, short-circuiting or malfunctioning.

If the screw is too tight, dropping or short-circuiting could occur due to screw damage.

Securely mount the connector of each connection cable to the mounting section.

An incomplete connection could lead to malfunctioning caused by an incorrect contact.

A - 3

[Wiring Instructions]

!CAUTION

Before starting installation or wiring work, be sure to shut off all phases of external power supply

used by the system.

Failure to shut off all phases could lead to electric shocks, product damage or malfunctioning.

Always install the terminal covers enclosed with the product before turning ON the power or

operating the product after installation or wiring work.

Failure to install the terminal cover could lead to electric shocks.

Always ground the FG terminal with Class D grounding (Class 3 grounding) dedicated of the

programmable controller.

Failure to do so could lead to malfunctioning.

Always confirm the product's rated voltage and terminal layout before wiring the module.

Connecting with a power supply other than the rated power supply, or incorrect wiring could

lead to fires or trouble.

Tighten the terminal screws within the specified torque range.

A loose terminal screw could lead to short-circuiting or malfunctioning.

If the terminal screw is too tight, dropping or short-circuiting could occur due to screw damage.

Make sure that foreign matter, such as cutting chips or wire scraps, do not enter the module.

Failure to observe this could lead to fires, trouble or malfunctioning.

The communication cables and power supply cable connected to the module must be placed in

a conduit or fixed with a clamp.

If the cable is not placed in a conduit or fixed with a clamp, the module or cable could be

damaged by the cable variation, movement or unintentional pulling leading to malfunctioning

caused by an improper cable connection.

Do not install the control lines together with the communication cables, or bring them close to

each other. Failure to do so may cause malfunctions due to noise.

Do not remove the communication cable or power supply cable connected to the module by

pulling on the cable section.

If the cable has a connector, hold the connector at the section connected to the module, and

remove.

If the cable does not have a connector, loosen the screws at the section connected to the

module, and remove.

Pulling on the cable while connected to the module could lead to module or cable damage, or

malfunctioning caused by an improper cable connection.

A - 4

[Startup/Maintenance Instructions]

!CAUTION

When power is ON, do not touch the terminals.

Doing so can cause an electric shock or malfunction.

Before cleaning or tightening the terminal screws and module mounting screws, be sure to shut

off all phases of external power supply used by the system.

Failure to shut off all phases could lead to module trouble or malfunctioning.

Do not touch the connector inside the lid at the front of the module.

Failure to observe this could lead to module trouble or malfunctioning.

Never disassemble or modify the module.

Failure to observe this could lead to trouble, malfunctioning, injuries or fires.

Do not drop or apply any strong impact to the module. Doing so may damage the module.

Before installing or removing the module on the panel, be sure to shut off all phases of external

power supply used by the system.

Failure to shut off all phases could lead to module trouble or malfunctioning.

Do not install/remove the terminal block more than 50 times after the first use of the product.
