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.

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

Install a safety circuit external to the PLC that keeps the entire system safe even when there

are problems with the external power supply or the PLC module. Otherwise, trouble could result

from erroneous output or erroneous operation.

(1) Outside the PLC, construct mechanical damage preventing interlock circuits such as

emergency stop, protective circuits, positioning upper and lower limits switches and

interlocking forward/reverse operations.

(2) When the PLC detects the following problems, it will stop calculation and turn off all output

in the case of (a). In the case of (b), it will stop calculation and hold or turn off all output

according to the parameter setting.

Note that the AnS series module will turn off the output in either of cases (a) and (b).

(a) The power supply module has over current protection equipment and over voltage

protection equipment.

(b) The PLC CPUs self-diagnosis functions, such as the watch dog timer error, detect

problems.

In addition, all output will be turned on when there are problems that the PLC CPU cannot

detect, such as in the I/O controller. Build a fail safe circuit exterior to the PLC that will make

sure the equipment operates safely at such times. See section 9.1 of this manual for

example fail safe circuits.

(3) Output could be left on or off when there is trouble in the outputs module relay or transistor.

So build an external monitoring circuit that will monitor any single outputs that could cause

serious trouble.

A - 2

[DESIGN PRECAUTIONS]

!DANGER

When overcurrent which exceeds the rating or caused by short-circuited load flows in the output

module for a long time, it may cause smoke or fire. To prevent this, configure an external safety

circuit, such as fuse.

Build a circuit that turns on the external power supply when the PLC main module power is

turned on. If the external power supply is turned on first, it could result in erroneous output or

erroneous operation.

When a data link results in a communication error, the faulty station changes in operating status

depending on the used data link type.

(1) For the data link data, the data prior to the communication error will be held.

(2) The MELSECNET (II,/B,/10) remote I/O station will turn all output off.

(3) The MELSECNET/MINI-S3 remote I/O station will hold the output or turn all output off

depending on the E.C. remote setting.

Refer to the data link manuals regarding the method for setting the communication problem

station and the operation status when there are communication problem.

When connecting a peripheral device to the CPU module or connecting a personal computer or

the like to the intelligent function module to exercise control (data change) on the running PLC,

configure up an interlock circuit in the sequence program to ensure that the whole system will

always operate safely.

Also before exercising other control (program change, operating status change (status control))

on the running PLC, read the manual carefully and fully confirm safety.

Especially for the above control on the remote PLC from an external device, an immediate

action may not be taken for PLC trouble due to a data communication fault.

In addition to configuring up the interlock circuit in the sequence program, corrective and other

actions to be taken as a system for the occurrence of a data communication fault should be

predetermined between the external device and PLC CPU.

When configuring a system, do not leave any slots vacant on the base. Should there be any

vacant slots, always use a blank cover (A1SG60) or dummy module (A1SG62).

When the extension base A1S52B, A1S55B or A1S58B is used, attach the dustproof cover

supplied with the product to the module installed in slot 0.

If the cover is not attached, the module's internal parts may be dispersed when a short-circuit

test is performed or overcurrent/overvoltage is accidentally applied to the external I/O area.

A - 3

[DESIGN PRECAUTIONS]

!CAUTION

Do not bunch the control wires or communication cables with the main circuit or power wires, or

install them close to each other. They should be installed 100 mm (3.94 inch) or more from

each other. Not doing so could result in noise that would cause erroneous operation.

When controlling items like lamp load, heater or solenoid valve using an output module, large

current (approximately ten times greater than that present in normal circumstances) may flow

when the output is turned OFF to ON.

Take measures such as replacing the module with one having sufficient rated current.

[INSTALLATION PRECAUTIONS]

!CAUTION

Use the PLC in an environment that meets the general specifications contained in this manual.

Using this PLC 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.

Hold down the module loading lever at the module bottom, and securely insert the module

fixing latch into the fixing hole in the base unit.

Incorrect loading of the module can cause a malfunction, failure or drop.

When using the PLC in the environment of much vibration, tighten the module with a screw.

Tighten the screw in 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.

When installing extension cables, be sure that the connectors of base unit are installed

correctly. After installation, check them for looseness. Poor connections could cause an input or

output failure.

Correctly connect the memory cassette installation connector to the memory cassette. After

installation, be sure that the connection is not loose. A poor connection could cause an

operation failure.

Completely turn off the external power supply before loading or unloading the module. Not

doing so could result in electric shock or damage to the product.

Do not directly touch the module's conductive parts or electronic components. Touching the

conductive parts could cause an operation failure or give damage to the module.

A - 4

[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.

When turning on the power supply or operating the module after installation or wiring work, be

sure that the module's terminal covers are correctly attached. Not attaching the terminal cover

could result in electric shock.

!CAUTION

Be sure to ground the FG terminals and LG terminals to the protective ground conductor. Not

doing so could result in electric shock or erroneous operation.

When wiring in the PLC, be sure that it is done correctly by checking the product's rated voltage

and the terminal layout. Connecting a power supply that is different from the rating or incorrectly

wiring the product could result in fire or damage.

Do not connect multiple power supply modules in parallel.

Doing so could cause overheating, fire or damage to the power supply module.

External connections shall be crimped or pressure welded with the specified tools, or correctly

soldered. Imperfect connections could result in short circuit, fires, or erroneous operation.

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

result in short circuits, fire, or erroneous operation. Tightening the terminal screws too far may

cause damages to the screws and/or the module, resulting in fallout, short circuits, or

malfunction.

Be sure there are no foreign substances such as sawdust or wiring debris inside the module.

Such debris could cause fires, damage, or erroneous operation.

The module has an ingress prevention label on its top to prevent foreign matter, such as wire

offcuts, from entering the module during wiring.

Do not peel this label during wiring.

Before starting system operation, be sure to peel this label because of heat dissipation.

A - 5

[STARTUP AND MAINTENANCE PRECAUTIONS]

!DANGER

Do not touch the terminals while power is on.

Doing so could cause shock or erroneous operation.

Correctly connect the battery.

Also, do not charge, disassemble, heat, place in fire, short circuit, or solder the battery.

Mishandling of battery can cause overheating or cracks which could result in injury and fires.

Switch all phases of the external power supply off when cleaning the module or retightening the

terminal or module mounting screws. Not doing so could result in electric shock.

Undertightening of terminal screws can cause a short circuit or malfunction. Overtightening of

screws can cause damages to the screws and/or the module, resulting in fallout, short circuits,

or malfunction.

!DANGER
