•SAFETY PRECAUTIONS •
(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 Precautions]
!DANGER
•Depending on the GOT main unit, communication board, communication module or cable fault,
the output from the GOT interface module may remain ON or may remain OFF.
An external monitoring circuit should be provided to check for output signals which may lead to
a serious accident.
Not doing so can cause an accident due to false output or malfunction.
•If a communication fault (including cable disconnection) occurs during monitoring on the GOT,
communication between the GOT and PLC CPU is suspended and the GOT becomes
inoperative.
For bus connection : The CPU becomes faulty and the GOT inoperative.
For other than bus connection : The GOT becomes inoperative.
A system where the GOT is used should be configured to perform any significant operation to
the system by using the switches of a device other than the GOT on the assumption that a GOT
communication fault will occur.
Not doing so can cause an accident due to false output or malfunction.
•Do not use the GOT as the warning device that may cause a serious accident.
An independent and redundant hardware or mechanical interlock is required to configure the
device that displays and outputs serious warning.
Failure to observe this instruction may result in an accident due to incorrect output or
malfunction.

A - 2 A - 2
[Design Precautions]
!DANGER
•Incorrect operation of the touch switch(s) may lead to a serious accident if the GOT backlight is
gone out.
When the GOT backlight goes out, the display section turns black and causes the monitor
screen to appear blank, while the input of the touch switch(s) still remains active.
This may confuse an operator in thinking that the GOT is in “screensaver” mode, who then tries
to release the GOT from this mode by touching the display section, which may cause a touch
switch to operate.
Note that the following occurs on the GOT when the backlight goes out.
•The monitor screen disappears even when the screensaver is not set.
•The monitor screen will not come back on by touching the display section, even if the
screensaver is set.
!CAUTION
•Do not bundle the control and communication cables with main-circuit, power or other wiring.
Run the above cables separately from such wiring and keep them a minimum of 100mm apart.
Not doing so noise can cause a malfunction.
[Mounting Precautions]
!DANGER
•Before installing or removing the GOT main unit to or from an enclosure, always turn the GOT
power OFF before installing or removing the GOT main unit to or from an enclosure.
Not doing so can cause a module failure or malfunction.
•Before loading or unloading the communication board, communication module, external I/O
interface module or memory card interface module to or from the GOT, always turn the GOT
power OFF before loading or unloading the communication board, communication module,
external I/O interface module or memory card interface module to or from the GOT.
Not doing so can cause a module failure or malfunction.
!CAUTION
•The GOT should be used in the environment given in the general specifications of this user's
manual.
Not doing so can cause an electric shock, fire, malfunction or product damage or deterioration.
•When mounting the GOT main unit to an enclosure, tighten the mounting screws 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 the damage of the screws
or module.

A - 3 A - 3
[Mounting Precautions]
!CAUTION
•When loading the communication board, External I/O interface module or communication
module to the GOT main unit, fit it to the connection interface of the GOT and tighten the
mounting screws in the specified torque range.
Undertightening can cause a drop, failure or malfunction.
Overtightening can cause a drop, failure or malfunction due to the damage of the screws or
module.
•When loading the communication board to the GOT main unit, take care not to become injured
by the components that are installed or surrounding materials.
•When loading the communication board to the GOT main unit, remove any static electricity
accumulated on your body before engaging in work.
Otherwise, this may result in damage to the board.
[Wiring Precautions]
!DANGER
•Before starting wiring, always turn the GOT power OFF before starting wiring.
Not doing so may cause an electric shock, product damage or malfunction.
!CAUTION
•Please make sure to ground FG terminal of the GOT power supply unit by applying Class D
Grounding (Class 3 Grounding Method) or higher which is used exclusively for the GOT.
Not doing so may cause an electric shock or malfunction.
•Correctly wire the power supply module on the GOT after confirming the rated voltage and
terminal arrangement of the product.
Not doing so can cause a fire or failure.
•Tighten the terminal screws of the GOT power supply section in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or
module.
•Exercise care to avoid foreign matter such as chips and wire offcuts entering the module.
Not doing so can cause a fire, failure or malfunction.
•Plug the bus connection cable by inserting it into the connector of the connected module until it
"clicks".
After plugging, check that it has been inserted snugly.
Not doing so can cause a malfunction due to a contact fault.
•Plug the communication cable into the connector of the connected module and tighten the
mounting and terminal screws in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or
module.

[Test Operation Precautions]
!DANGER
•Before performing test operation (bit device on/off, word device's present value changing,
timer/counter's set value and present value changing, buffer memory's present value changing)
for a user-created monitor screen or system monitoring, read the manual carefully to fully
understand how to operate the equipment.
During test operation, never change the data of the devices which are used to perform
significant operation for the system.
False output or malfunction can cause an accident.
[Startup/Maintenance Precautions]
!DANGER
•When power is on, do not touch the terminals.
Doing so can cause an electric shock or malfunction.
•Before starting cleaning or terminal screw retightening, always turn the power OFF before
starting cleaning or terminal screw retightening.
Not switching the power off in all phases can cause a module failure or malfunction.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or
module.
!CAUTION
•Do not disassemble or modify the module.
Doing so can cause a failure, malfunction, injury or fire.
•Do not touch the conductive and electronic parts of the module directly.
Doing so can cause a module malfunction or failure.
•The cables connected to the module must be run in ducts or clamped.
Not doing so can cause the module or cable to be damaged due to the dangling, motion or
accidental pulling of the cables or can cause a malfunction due to a cable connection fault.
•When unplugging the cable connected to the module, do not hold and pull the cable portion.
Doing so can cause the module or cable to be damaged or can cause a malfunction due to a
cable connection fault.
