SAFETY PRECAUTIONS

(Read these precautions before using.)

When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in

this manual. Also pay careful attention to safety and handle the module properly.

The precautions given in this manual are concerned with this product. Refer to the user's manual of the

network system to use for a description of the network system safety precautions.

These SAFETY PRECAUTIONS classify the safety precautions into two categories: "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.

Depending on circumstances, procedures indicated by !CAUTION 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

forward it to the end user.

[DESIGN PRECAUTIONS]

!DANGER

Create an interlock circuit on the program so that the system will operate safety based on the

communication status information. Failure to so may cause an accident due to an erroneous

output or malfunction.

When an error occurs, all outputs are turned OFF in the MELSEC-ST system (at default).

However, I/O operations of the head module and respective slice modules can be selected for

the errors described below.

Select the status for each module for the entire system safety.

(1) Communication error (Head Module User’s Manual)

(2) Slice module error

The output status for the case of an error can be set to Clear, Hold or Preset with a

command parameter of each slice module. (For setting availability, refer to the manual for

each slice module.)

Since the parameter is defaulted to Clear, outputs will be turned off if an error occurs.

This parameter setting can be changed to Hold or Preset when the system safety is more

ensured by holding or presetting the output.

A - 2 A - 2

[DESIGN PRECAUTIONS]

!DANGER

Create an external fail safe circuit that will ensure the MELSEC-ST system operates safely,

even when the external power supply or the system fails.

Accident may occur due to output error or malfunctioning.

(1) The status of output changes depending on the setting of various functions that control the

output. Take sufficient caution when setting for those functions.

(2) Output may be kept ON or OFF due to malfunctions of an output element or its internal

circuits.

For signals which may cause a serious accident, configure an external monitoring.

!CAUTION

Make sure to initialize the network system after changing parameters of the MELSEC-ST

system or the network system. If unchanged data remain in the network system, this may cause

malfunctions.

Do not install the control wires or communication cables together with the main circuit or power

wires. Keep a distance of 100 mm (3.94 inch) or more between them. Not doing so could result

in malfunctions due to noise.

[INSTALLATION PRECAUTIONS]

!CAUTION

Use the MELSEC-ST system in the general environment specified in the MELSEC-ST system

users manual. Using this MELSEC-ST system in an environment outside the range of the

general specifications could result in electric shock, fire, erroneous operation, and damage to or

deterioration of the product.

Mount the head module and base module on the DIN rail securely (one rail for one module)

referring to the MELSEC-ST system users manual and then fix them with end brackets.

Incorrect mounting may result in a drop of the module, short circuits or malfunctions.

Secure the module with several end brackets when using it in an environment of frequent

vibration. Tighten the screws of the end brackets within the specified torque range.

Undertightening can cause a drop, short circuit or malfunction. Overtightening can cause a

drop, short circuit or malfunction due to damage to the screw or module.

A - 3 A - 3

[INSTALLATION PRECAUTIONS]

!CAUTION

Make sure to externally shut off all phases of the power supply for the whole system before

mounting or removing a module. Failure to do so may damage the module.

(1) Online replacement of the power distribution module and/or the base module is not

available. When replacing either of the modules, shut off all phases of the external power

supply.

Failure to do so may result in damage to all devices of the MELSEC-ST system.

(2) The I/O modules and the intelligent function modules can be replaced online.

Since online replacement procedures differ depending on the module type, be sure to make

replacement as instructed.

For details, refer to the chapter describing the online module change in the user’s manual of

the head module (for the I/O module) or the corresponding intelligent function module.

Do not directly touch the module's conductive parts or electronic components. Doing so may

cause malfunctions or failure of the module.

Make sure to securely connect each cable connector. Failure to do so may cause malfunctions

due to poor contact.

DIN rail must be conductive; make sure to ground it prior to use. Failure to do so may cause

electric shocks or malfunctions. Undertightening can cause a drop, short circuit or malfunction.

Overtightening can cause a drop, short circuit or malfunction due to damage to the screw or

module.

[WIRING PRECAUTIONS]

!DANGER

Completely turn off the external power supply when installing or placing wiring. Not completely

turning off all power could result in electric shock or damage to the product.

!CAUTION

Make sure to ground the control panel where the MELSEC-ST system is installed in the manner

specified for the MELSEC-ST system. Failure to do so may cause electric shocks or

malfunctions.

Check the rated voltage and the terminal layout and wire the system correctly. Connecting an

inappropriate power supply or incorrect wiring could result in fire or damage.

Tighten the terminal screws within the specified torque. If the terminal screws are loose, it could

result in short circuits, fire, or erroneous operation. Overtightening may cause damages to the

screws and/or the module, resulting in short circuits or malfunction.

A - 4 A - 4

[WIRING PRECAUTIONS]

!CAUTION

Prevent foreign matter such as chips or wiring debris from entering the module. Failure to do so

may cause fires, damage or erroneous operation.

When connecting the communication and power supply cables to the module, always run them

in conduits or clamp them. Not doing so can damage the module and cables by pulling a

dangling cable accidentally or can cause a malfunction due to a cable connection fault.

When disconnecting the communication and power supply cables from the module, do not hold

and pull the cable part. Disconnect the cables after loosening the screws in the portions

connected to the module. Pulling the cables connected to the module can damage the module

and cables or can cause a malfunction due to a cable connection fault.

[STARTUP AND MAINTENANCE PRECAUTIONS]

!DANGER

Do not touch the terminals while power is on.

Doing so could cause shock or erroneous operation.

Make sure to shut off all phases of the external power supply for the system before cleaning the

module or tightening screws.

Not doing so can cause the module to fail or malfunction.

!CAUTION

Do not disassemble or modify the modules.

Doing so could cause failure, erroneous operation, injury or fire.

Do not drop or give a strong impact to the module since its case is made of resin. Doing so can

damage the module.

Make sure to shut off all phases of the external power supply for the system before mounting/

removing the module onto/from the control panel. Not doing so can cause the module to fail or

malfunction.

The number of terminal block installations/removals is limited to 50 times or less.

(Compliant with JIS B 3502)

Exceeding the count of 50 may cause malfunctions.

A - 5 A - 5

[STARTUP AND MAINTENANCE PRECAUTIONS]

!CAUTION

Before handling the module, make sure to touch a grounded metal object to discharge the static

electricity from the human body.

Failure to do say cause a failure or malfunctions of the module.

When using any radio communication device such as a cellular phone, keep a distance of at

least 25cm (9.85 inch) away from the MELSEC-ST system.

Not doing so can cause a malfunction.

[DISPOSAL PRECAUTIONS]

!CAUTION

When disposing of this product, treat it as industrial waste.
