PROFACE PL-B910 Series User Manual page 3

Preface
• When a problem occurs with the PL's backlight or display
that causes the screen to go blank, the touch-panel may
still be active, since it is a separate unit. In such a case,
do not operate the touch panel, since an unexpected ma-
chine action or movement may occur, which may in turn
cause machine damage or operator injury.
• 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 PL distributor or the Digital Electronics Corporation.
• Read and understand Chapter 4 "Installation and Wiring"
thoroughly in order to select an appropriate installation
location for the PL.
• Before either plugging in or unplugging a board or inter-
face connector, be sure to turn the PL's power OFF.
• To prevent a possible explosion, do not install the PL in
areas containing flammable gases.
• The PL is not appropriate for use with aircraft control
devices, aerospace equipment, central trunk data trans-
mission (communication) devices, nuclear power control
devices, or medical life support equipment, due to these
devices' inherent requirements of extremely high levels of
safety and reliability.
• When using the PL with transportation vehicles (trains,
cars and ships), disaster and crime prevention devices,
various types of safety equipment, non-life support re-
lated medical devices, etc. redundant and/or failsafe sys-
tem designs should be used to ensure the proper degree
of reliability and safety.
