Warnings
Warnings for Design
Designing switches that might cause human injuries and/or property damage on the
touchscreen is strictly prohibited. Unintended output signals due to malfunction of the main
unit and/or cables can lead to serious injuries. Design the system so that switches that
perform critical operations are equipped on devices other than the STM itself.
Designing safety related switches on the STM is prohibited. Switches related to safety, such
as emergency stop switches, should be installed on a different hardware.
Do not use this product as a critical warning device that may cause injuries, serious property
damage, or production stoppage. Critical warning indications and alert-related controls
should be structured on an independent and redundant hardware or mechanical interlocks.
The STM is not intended for use in applications that require extremely high reliability and
safety such as aircraft equipment, aerospace equipment, trunk line communication
equipment, nuclear power control equipment, and life sustaining medical equipment. It is not
intended for use in these applications.
When using the STM for purposes that concerns high reliability and safety in terms of
functions and accuracy such as transport equipment (trains, automobiles, ship, etc.), disaster
prevention and security equipment, various safety devices, medical equipment that does not
concern life sustaining, be sure to have safety features including redundancy and
malfunction prevention measures into the entire system which it will be incorporated.
Display will black out when the backlight goes out. If mistakenly operated in this condition, it
might result in improper operation. Do not design touch-switches that might cause human
injuries and material damages due to improper operation on the STM.
Warnings for Handling
Do not modify or disassemble the STM. Doing so may cause fire and /or electric shock.
Do not use around flammable gas. It may cause explosions.
Do not allow any kind of liquid, such as water, and metals to get inside of the product. It may
cause fire and/or electric shock.
In any abnormality such as smoke, unusual odor, or unusual noise is detected, disconnect
the power plug, and discontinue use. If use is continued, it may cause fire or electric shock.
Warnings for Wiring
For proper wiring and installation, please refer to the manual and specifications. Failure to
do so may cause fires and/or electric shocks
Before installing the power cable, make sure power is not being supplied from the power
source. Failure to do so may cause electrical shocks.
Do not use power voltage other than what is specified. Failure to do so may cause fires and/or
electric shocks.
