described in this manual.
Not doing so can cause an electric shock, fire, mal function or product
damage or deterioration.
When mounting the GOT to the control panel, tighten the mounting screws in
the specified torque range.
Undertightening can cause the GOT to drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malf unction due to the
damage of the screws or the GOT.
When inserting a CF card into the GOT, push it into the insertion slot until the
CF card eject button pops out.
If not properly inserted, a bad connection may caus e a malfunction.
When inserting/removing a CF card into/from the GOT, turn the CF card
access switch off in advance.
Failure to do so may corrupt data within the CF card
When removing a CF card from the GOT, make sure to support the CF card
by hand, as it may pop out.
Failure to do so may cause the CF card to drop from the GOT and break.
Remove the protective film of the GOT.
When the user continues using the GOT with the protective film, the film may
not be removed.
Operate and store the GOT in environments without direct sunlight, h igh
temperature, dust, humidity, and vibrations.
[DESIGN PRECAUTIONS]
Some failures of the GOT, communication unit or cable may keep the outputs
on or 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 outp ut or malfunction.
If a communication fault (including cable disconnection) occ urs during
monitoring on the GOT, communication between the GOT and PLC CPU is
suspended and the GOT becomes inoperative.
A system where the GOT is used should be confi gured to perform any
significant operation to the system by using the sw itches of a device other
than the GOT on the assumption that a GOT communi cation fault will occur.
Not doing so can cause an accident due to false outp ut or malfunction.
Do not use the GOT as the warning device that may cause a seriou s
accident.
An independent and redundant hardware or mechanic al interlock is required
to configure the device that displays and outputs se rious warning.
Failure to observe this instruction may resul t in an accident due to incorrect
output or malfunction.
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 POWER LED flic kers (green/orange)
and the display section turns black and causes the mo nitor screen to appear
blank, while the input of the touch switch(s) remains a ctive.
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 tou ch switch to operate.
Note that the following occurs on the GOT when the b acklight goes out.
• The POWER LED flickers (green/orange) and the moni tor screen appears
blank
The display section of the GT12 is an analog-resistive t ype touch panel.
If you touch the display section simultaneously in 2 points or mor e, the switch
that is located around the center of the touched poin t, if any, may operate.
Do not touch the display section in 2 points or more simultaneously.
Doing so may cause an accident due to incorrect o utput or malfunction.
When programs or parameters of the controller (such as a PLC) that is
monitored by the GOT are changed, be sure to reset the GOT or shut off the
power of the GOT at the same time.
Not doing so can cause an accident due to false outp ut or malfunction.
Do not bundle the control and communication cables with main-circui t, power
or other wiring.
Run the above cables separately from such wiring and kee p them a minimum
of 100mm apart.
Not doing so noise can cause a malfunction.
Do not press the GOT display section with a pointed material a s a pen or
driver.
Doing so can result in a damage or failure of the dis play section.
[WIRING PRECAUTIONS]
Be sure to shut off all phases of the external power supply used by the
system before wiring.
Failure to do so may result in an electric shock, p roduct damage or
malfunctions.
[WIRING PRECAUTIONS]
Always ground the FG terminal, LG terminal, and protective ground term inal
of the GOT power to the protective ground conductors dedicated to the GOT.
Not doing so may cause an electric shock or malfunction.Terminal screws
which are not to be used must be tightened always at torque 0.5 to 0.8 N•m.
Otherwise there will be a danger of short circuit agai nst the solderless
terminals.
Use applicable solderless terminals and tighten them with the specified
torque.
If any solderless spade terminal is used, it may be disconnected
when the terminal screw comes loose, resulting in failu re.
Correctly wire the GOT power supply section 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 i n the specified
torque range. Undertightening can cause a short ci rcuit or malfunction.
Overtightening can cause a short circuit or mal function due to the damage of
the screws or the GOT.
Exercise care to avoid foreign matter such as chips and wire offcuts entering
the GOT. Not doing so can cause a fire, failure or malfunction.
The module has an ingress prevention label on its top to preven t 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.
Plug the communication cable into the connector of the connected unit and
tighten the mounting and terminal screws in the specified torque range.
Undertightening can cause a short circuit or ma lfunction.
Overtightening can cause a short circuit or mal function due to the damage of
the screws or unit.
[TEST OPERATION PRECAUTIONS]
Before performing the test operations of the user creation monito r screen
(such as turning ON or OFF bit device, changing the word device current
value, changing the settings or current values of the timer or counter, and
changing the buffer memory current value), read through th e manual
carefully and make yourself familiar with the oper ation method.
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]
When power is on, do not touch the terminals.
Doing so can cause an electric shock or malfuncti on.
Correctly connect the battery connector.
Do not charge, disassemble, heat, short-circuit, sold er, or throw the battery
into the fire.
Doing so will cause the battery to produce heat, explode, or ignite, resulting in

5.1.2 Control panel
The GOT is an open type device (device installed to another device) and
must be installed in a conductive control panel.
It not only assure the safety but also has a large effect to shut down the
noise generated from GOT, on the control panel.
(1) Control Panel
(a) The control panel must be conductive.
(b) When fixing a top or bottom plate of the control panel wit h bolts,
do not coat the plate and bolt surfaces so that they will come into
contact.
And connect the door and box using a thick grounding cable in
order to ensure the low impedance under high frequency.
(c) When using an inner plate to ensure electric conductivity with the
control panel, do not coat the fixing bolt area of the inner plate
and control panel to ensure conductivity in the largest area as
possible.
(d) Ground the control panel using a thick grounding cable in order to
ensure the low impedance under high frequency.
(e) The diameter of cable holes in the control panel must be 10cm
(3.94in.). In order to reduce the chance of radio waves leaking
out, ensure that the space between the control panel and its door
is small as possible.
Paste the EMI gasket directly on the painted surface to seal the
space so that the leak of electric wave can be suppressed.
Our test has been carried out on a panel having the damping
characteristics of 37dB max. and 30dB mean (measured by 3m
method with 30 to 300MHz).
(2) Connection of power and ground wires
Ground and power supply wires for the GOT must be connected as
described below.
(a) Provide a grounding point near the GOT. Short-circuit the LG and
FG terminals of the GOT (LG: line ground, FG: frame ground)
and ground them with the thickest and shortest wire possible
(The wire length must be 30cm (11.81in.) or shorter.)
The LG and FG terminals function is to pass the noise generated
in the PC system to the ground, so an impedance that is as low
as possible must be ensured. As the wires are used to relieve the
noise, the wire itself carries a large noise content and thus short
wiring means that the wire is prevented from acting as an
antenna.
Note) A long conductor will become a more efficient antenna at
high frequency.
(b) The earth wire led from the earthing point must be twisted with
the power supply wires.
By twisting with the earthing wire, noise flowing from the power
supply wires can be relieved to the earthing. However, if a filter is
installed on the power supply wires, the wires and the earthing
wire may not need to be twisted.
5.1.3 Noise filter (power supply line filter)
The noise filter (power supply line filter) is a device effective to reduce
conducted noise. Except some models, installation of a noise filter onto
the power supply lines is not necessary. However conducted noise can
be reduced if it is installed. (The noise filter is generally effective for
reducing conducted noise in the band of 10MHz or less.) Usage of the
following filters is recommended.
Model name FN343-3/01 FN660-6/06 ZHC2203-11
Manufacturer SCHAFFNER SCHAFFNER TDK
Rated current 3A 6A 3A
Rated voltage 250V
The precautions required when installing a noise filter are described
below.
(1) Do not install the input and output cables of the noise filter together
to prevent the output side noise will be inducted into the input side
cable where noise has been eliminated by the noise filer.

5.2 Requirements for Compliance with the Low Voltage Directive
The Low Voltage Directive requires each device which operates with
power supply ranging from 50VAC to 1000V and 75VDC to 1500V to
satisfy necessary safety items.
In the Sections from
the GOT to conform to the Low Voltage Directive requires are described.
We have put the maximum effort to develop this material based on the
requirements and standards of the Directive that we have collected.
However, compatibility of the devices which are fabricated according to
the contents of this manual to the above Directive is not guaranteed.
Each manufacturer who fabricates such device should make the final
judgement about the application method of the Low Voltage Directive
and the product compatibility.

5.2.3 Control panel
Because the GOT is open type equipment (device designed to be stored
within another device), be sure to use it only when installed in a control
panel.
(1) Shock Protection
In order to prevent those who are unfamiliar with power facility,
e.g., an operator, from getting a shock, make sure to take the
following measures on the control panel.
(a) Store the GOT within the control panel locked, and allow only
those who are familiar with power facility to unlock the panel.
(b)Build the structure in order that the power supply will be shut off
when the control panel is opened.
(2) Dustproof and waterproof features
The control panel also provides protection from dust, water and
other substances. Insufficient ingression protection may lower the
insulation withstand voltage, resulting in insulation destruction.
The insulation in the GOT is designed to cope with the pollution
level 2, so use in an environment with pollustion level 2 or better.
Pollution level 1: An env ironment where the air is dry and conductive
