WARNINGS
System Design
• Do not create ST touch panel switches that could possibly endanger the safety
of equipment and personnel. Damage to the ST, its I/O unit(s), cable(s), and
other related equipment can cause an output signal to remain continuously ON
or OFF and possibly cause a major accident. Therefore, design all monitoring
circuits using limit switches, etc. to detect incorrect device movement. To pre-
vent accidents related to incorrect signal output or operation, design all switches
used to control vital machine operations so they are operated via a separate
control system.
• Do not create switches used to control machine safety operations, such as
an emergency stop switch, using a ST touch screen icon. Be sure to install
these switches as separate hardware switches, otherwise severe bodily in-
jury or equipment damage can occur.
• Please design your system so that equipment will not malfunction due to a
communication fault between the ST and its host controller. This is to pre-
vent any possibility of bodily injury or material damage.
• Do not use the ST unit as a warning device for critical alarms that can cause
serious operator injury, machine damage or production stoppage. Critical
alarm indicators and their control/activator units must be designed using stand-
alone hardware and/or mechanical interlocks.
• The ST is not appropriate for use with aircraft control devices, aerospace
equipment, central trunk data transmission (communication) devices, nuclear
power control devices, or medical life support equipment, due to these de-
vices' inherent requirements of extremely high levels of safety and reliability.
• When using the ST with transportation vehicles (trains, cars and ships), di-
saster and crime prevention devices, various types of safety equipment, non-
life support related medical devices, etc. redundant and/or failsafe system
designs should be used to ensure the proper degree of reliability and safety.
• After the ST backlight burns out, unlike the ST's standby Mode, the touch
panel is still active. If the operator fails to notice that the backlight is burned
out and touches the panel, a potentially dangerous machine operation error
can occur. Therefore, do not use ST touch switches for the control of equip-
ment safety mechanisms, such as Emergency Stop switches, etc. that pro-
tect humans and equipment from injury and damage. If your ST's backlight
suddenly turns OFF, use the following steps to determine if the backlight is
actually burned out.
1)If your ST is not set to Standby Mode and the screen has gone blank, your
backlight is burned out.
2)Or, if your ST is set to Standby Mode, but touching the screen does not
cause the display to reappear, your backlight is burned out.
Installation
• Do not modify the ST unit. Doing so may cause a fire or an electric shock.
• Do not use the ST in an environment where flammable gasses are present,
since operating the ST may cause an explosion.
Wiring
• To prevent an electric shock, be sure to confirm that the ST's power cord is
not connected to the main power when connecting any cords, cables or lines
to the ST.
• Do not use power beyond the ST's specified voltage range. Doing so may
cause a fire or an electric shock.
Maintenance
• The ST uses a lithium battery for backing up its internal clock data. If the battery is
incorrectly replaced, the battery may explode. To prevent this, please do not
replace the battery yourself. When the battery needs to be replaced, please con-
tact your local ST distributor.

E-2
CAUTIONS
Installation
• Be sure to securely connect all cable connectors to the ST. A loose con-
nection may cause incorrect input or output.
Wiring
• Ground the ST's FG line separately from other unit FG lines. Locating FG
lines too close may cause an electric shock or a unit malfunction. Be sure to
use a grounding resistance of 100Ωor less and a 2mm2or thicker wire, or
your country applicable standard.
• When wiring the ST, be sure that the rated voltage and terminal layout are
within the designated range. If the voltage supplied differs from the rated
voltage, or incorrect wiring or grounding is performed, it may cause a fire or
unit malfunction.
• Use only the designated torque to tighten the ST's terminal block screws. If
these screws are not tightened firmly, it may cause a short-circuit, fire, or ST
malfunction.
• Be careful that metal filings and wiring debris do not fall inside the ST, since
they can cause a fire, ST malfunction, or operation error.
Maintenance
• The liquid crystal panel contains a powerful irritant and if for any reason the
panel is damaged and this liquid contacts any part of your body, be sure to
wash that area with running water for 15 minutes. If any of this liquid enters
your eye, flush your eye for 15 minutes with running water and contact a
physician.
Unit Disposal
• When this unit is disposed of, it should be done so according to your country's
regulations for similar types of industrial waste.
Other
• Among backlight units there may be slight variations in illumination color,
however, this does not effect the performance or quality of the ST unit.
General Safety Precautions
• Do not strike the touch panel with a hard or pointed object, or press on the
touch panel with too much force, since it may damage the touch panel or the
display.
• Do not install the ST where the ambient temperature can exceed the al-
lowed range. Doing so may cause the ST to malfunction or shorten its op-
eration life.
• Do not restrict or limit the ST unit naturally occurring rear-face ventilation, or
storing or using the ST in an environment that is too hot.
• Do not use this unit in areas where large, sudden temperature changes can
occur. These changes can cause condensation to form inside the unit, pos-
sibly causing the unit to malfunction.
• Do not allow water, liquids, metal or charged particles to enter inside the ST
case, since they can cause either a ST malfunction or an electrical shock.
The allowable pollution degree is 2.
• Do not use or store the ST in direct sunlight, or in excessively dusty or dirty
environments.
• Do not store or use the unit where strong jolting or excessive vibration can
occur.

E-3
• Do not store or use the ST where chemicals (such as organic solvents, etc.)
and acids can evaporate, or where chemicals and acids are present in the
air.
Corrosive chemicals: Acids, alkalines, liquids containing salt
Flammable chemicals: Organic Solvents
• Do not use paint thinner or organic solvents to clean the ST.
• Do not store or operate the LCD display in areas receiving direct sunlight,
since the sun's UV rays may cause the LCD display quality to deteriorate.
• Storing this unit in areas at a temperature lower than is recommended in this
manual's specifications may cause the LCD display liquid to congeal,
which may damage the panel. Conversely, if the storage area temperature
becomes higher than the allowed level, the LCD liquid will become isotro-
pic, causing irreversible damage to the LCD. Therefore, be sure to store
the panel only in areas where temperatures are within those specified in this
manual.
• After turning the ST OFF, be sure to wait a few seconds before turning it
ON again. If the ST is restarted too soon, it may not start up correctly.
• Due to the possibility of unexpected accidents, be sure to back up the ST
screen data regularly.
About the ST’s Display Panel
• The ST's currently displayed data, its voltage*1 and brightness setting each
affect the intensity of Contouring. (i.e, when some parts of the screen are
brighter than others, creating a wavelike pattern)
• There are minute grid-points (dark and light) on the Display Panel’s surface.
This is part of the ST’s design and not a defect.
• Extended shadows, or “Crosstalk” may appear on the sides of screen im-
ages. This is normal for an LCD display.
• Sometimes the display area may look as if the display colors have changed.
This is a common attribute of LCD’s and is not a defect.
• Displaying a single image for long periods can cause an afterimage to re-
main when the display is changed to another screen.
* Use the ST’s “Stand-by Mode”, which automatically turns the screen OFF
when there is no input for a specified period of time.
* Do not display any single screen for a long period of time. Try to
periodically change the screen display.
This mark is applicable only in Taiwan.

Confirm the Installation Gasket's Positioning
It is strongly recommended that you use the gasket. It absorbs vibration in addition
to repelling water.
Place the ST on a level surface with the display panel facing downward. Check that
the ST’s installation gasket is seated securely into the gasket’s groove, which runs
around the perimeter of the panel’s frame.
• Before installing the ST into a cabinet or panel, check that the instal-
lation gasket is securely attached to the unit.
• A gasket which has been used for a long period of time may have
scratches or dirt on it, and could have lost much of its dust and drip
resistance. Be sure to change the gasket periodically (or when
scratches or dirt become visible).
• Be sure the gasket's seam is not inserted into any of the unit's cor-
ners, only in the straight sections of the groove. Inserting it into a
corner may lead to its eventually tearing.
• To ensure the installation gasket's maximum level of moisture resis-
tance, be sure the gasket's seam is inserted as shown into the
panel's bottom face.

• To avoid an electric shock, prior to connecting the ST's power
cord confirm that the ST's power supply is completely turned OFF,
via a breaker, or similar unit.
• The ST400-AG41-24V/ST401-AG41-24V/ST402-AG41-24V /
ST403-AG41-24V units are designed to use only DC24V input.
Any other power level can damage both the ST and the power
supply.
• Since there is no power switch on the ST unit, be sure to attach a
breaker-type switch to its power cord.
• When the FG terminal is connected, be sure the cord is grounded.
• If the power cord is pulled strongly, the power plug may fall out.
• When the FG terminal is connected, be sure the wire is grounded.
Not grounding the ST unit will result in excess noise and vibration.
