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 precautions apply only to Mitsubishi equipment. Refer to the CPU
module user's manual for a description of the PC system safety precautions.
These •
SAFETY PRECAUTIONS• classify the safety precautions into two
categories: "DANGER" and "CAUTION".
DANGER
Procedures which may lead to a dangerous
condition and cause death or serious injury if not
carried out properly.
CAUTION
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
[WIRNG INSTRUCTIONS]
CAUTION
!
The communication and power cables connected to the module must be
fixed securely, e.g. contained in ducts or clamped.
A failure to do so could cause the cables to dangle, move, or be carelessly
pulled, leading to a damaged module or cable or a malfunction due to a
cable connection fault.
[STARTING AND MAINTENANCE PRECAUTIONS]
DANGER
!
While power is on, do not touch the terminals.Otherwise, an electric shock
or malfunction could occur.
!
Before starting cleaning or terminal screw retightening, always switch off
external GOT power in all phases.
A failure to do so could cause an electric shock.
Undertightening could cause the module to drop, short-circuit or
malfunction.
Overtightening could cause the module to drop, short-circuit or malfunction
CAUTION
!
Do not disassemble or modify this module.
Otherwise, a failure, malfunction, injury or fire could occur.
!
Do not touch the conducive and electronic parts of this module directly.
Otherwise, the module could malfunction or fail.
!
This module is made of resin. Do not drop it or subject it to hard impact.
This may cause the module to fail.
!
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.

A-4
[DISPOSAL PRECAUTIONS]
CAUTION
!
When disposing of this product, treat it as industrial waste.
