Essential Safety Precautions
Be sure to follow the instructions given below to ensure the safe use of the PL.
To avoid a possiblity of electrical shock, be sure to connect the power cord
to the PL before connecting it to the main power supply.
A fire or electrical shock may result if voltages are used with the PL that are
beyond the specified range. Be sure to only use the specified voltage.
Before opening the PL’s protective cover, be sure to turn the unit’s power
OFF. This is because the PL’s internal parts carry high voltages.
To avoid fires or electrical hazards, do not modify the product in any way.
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 control
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 location 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 areas contain-
ing flammable gases.
The PL is not appropriate for use with aircraft control devices, aero-
space equipment, central trunk data transmission (communication)
devices, nuclear power control devices, or medical life support equip-
ment, 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 equip-
ment, 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.
Do not push on the PL’s screen too strongly, with either your finger or
