Preface
Before replacing the 100V unit's backlight, be sure to turn
the unit's power OFF to avoid electrical shocks. (Note: Do
NOT attempt to replace the 24V unit's backlight)
Do not create touch panel switches that are used to either
control or to ensure the safety of equipment and personnel.
Mechanical switches, such as an emergency stop switch, a
deadman (two-handed) start switch, etc., must be installed
and operated via a separate system.
If metal particles, water or other types of liquids contact any
of the PL's internal parts, immediately turn the unit's power
OFF, unplug the power cord, and contact either your dealer
or Digital Electronics Corporation.
Read and understand Chapter 4 "Installation and Wiring"
thoroughly in order to select an appropriate installation loca-
tion for the PL.
Before either plugging in or unplugging a board or interface
connector, be sure to turn the PL's power OFF.
To prevent a possible explosion, do not install the PL in ar-
eas containing flammable gases.
General Safety Precautions
Follow the instructions given below for correct and safe use of the PL.
• Do not push on the PL's screen too strongly, with either your
finger or with a hard object. Excessive pressure can
scratch, crack or damage the screen.
• If the screen becomes dirty or smudged, moisten a soft cloth
with diluted neutral detergent, wring the cloth well, and wipe
the display. Do not use thinner or organic solvents.
• Do not use a pointed object, such as a mechanical pencil or
screwdriver, to press any of the touch panel's switches,
since they can damage the display.
• Avoid exposing and operating the PL in direct sunlight, high
temperatures and humidity, and in areas where excessive
dust and vibration will occur.
