DANGER

CAUTION

!SAFETY PRECAUTIONS !

(Always read before starting use)

When using Mitsubishi equipment, thoroughly read this manual and the

associated manuals introduced in the manual. Also pay careful attention to

safety and handle the module properly.

These precautions apply only to the installation of Mitsubishi equipment and the

wiring with the external device. Refer to the user’s manual of the CPU module

to be used for a description of the PLC system safety precautions.

These SAFETY PRECAUTIONS classify the safety precautions into two

categories: "DANGER" and "CAUTION".

Procedures which may lead to a dangerous condition and

cause death or serious injury if not carried out properly.

Procedures which may lead to a dangerous condition and

cause superficial to medium injury, or physical damage

only, if not carried out properly.

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

!Some faults of the GOT, this unit or connection cables may keep the

outputs on or off.

An external monitoring circuit should therefore be provided to check for

output signals which may lead to a serious accident.

Otherwise, mis-output or misoperation can cause an accident.

A-2

[INSTALLATION PRECAUTIONS]

DANGER

!When installing and removing this module from the GOT main module be

sure to shut off the power at all external switches. If all the switches are not

turned off, the module could be damaged or malfunction.

!When connecting the bus connection cable to this module be sure to turn

off the switch to all external power switches to the GOT and PC CPU. If all

the switches are not turned off, it may cause malfunction.

CAUTION

!Use this module in an environment that is within the general specifications

written in the GOT User's Manual. If the power supply is used in an

environment that is outside of the general specifications then electric

shock, fire, malfunction, or product damage or degradation could occur.

!For a correct installation, insert the bus connection cable to this module,

A7GT-BUS2S, bus connector conversion module, and base unit connector

until you hear it click.

A bad connection could cause erroneous input or output.

!When installing this module in the GOT main module, install it in the GOT

installation area and be sure it is fastened with a module fastening screw

that is tightened within the specified torque range.

If the module fixing screws are loosen, it may cause malfunction, damage

or falling of the module.

If the module fixing screws are too tight, the GOT main module or the

screws could break.

[Wiring Instructions]

DANGER

!Before starting wiring, always switch off all phases of the power supply

externally.

CAUTION

!During wiring, care should be taken so that foreign matter such as shield

and wire offcuts do not enter this unit.

Otherwise, a fire, fault or misoperation can occur.

A-3

[STARTING AND MAINTENANCE PRECAUTIONS]

DANGER

!Do not change the switch setting while power is on.

!Switch all phases of the GOT external power supply off before cleaning.

Not doing so could result in electric shock.

CAUTION

!Never disassemble or modify the module. This may cause breakdowns,

malfunctioning, injury, and/or fire.

!Do not directly touch the conducted area and electric parts of this module.

It may cause damage and malfunctioning of the module.

!This module is made of resinous materials, and should be protected from

strong shock or impact. It may cause breakdown.

!When disconnecting the communication or power cable from the module,

do not hold and pull the cable part.

When disconnecting the cable having a connector, hold the connector

plugged in the module.

Before disconnecting the cable having no connector, loosen the screws in

the module.

If the cable connected to the module is pulled, the module or cable may be

damaged or a malfunction may occur due to a cable connection fault.

!Before handling the unit, touch a grounded metal or similar object to

discharge the static electricity from the human body.

Failure to do so may cause the unit to fail or mulfunction.

[DISPOSAL PRECAUTIONS]

CAUTION

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