FP790-T21
Installation Guide
• Do not push on the FPs screen too strongly, with either your finger or with a hard object.
Excessive pressure can scratch, crack or damage the screen. Do not use a pointed object,
such as a mechanical pencil or screwdriver, to press any of the touch panel’s switches, since
it can damage the display.
• 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.
• Avoid storing and operating the FP in direct sunlight, high temperatures and humidity, and in
areas where excessive dust and vibration will occur.
• Avoid using the FP in areas where sudden, extreme changes in temperature can occur. This
may cause condensation to form inside the unit, possibly leading to an accident.
• To prevent the FP from overheating, be sure its air circulation vents are clear and clean, and
keep the unit’s operation area well-ventilated.
• Avoid operating or storing the FP near chemicals, or where chemicals can come into contact with the
unit.
CAUTIONS
WARNINGS
• To prevent an electric shock, be sure to turn FP-790 unit’s (hereafter referred to as the “FP”) main
power supply OFF before attaching the power cord terminals to the FP unit’s power terminal strip.
• A fire or electrical shock may occur if voltages used with the FP are beyond the specified
range. Be sure to use only the specified voltage.
• Before opening the FP unit’s protective cover, be sure to turn the unit’s power OFF. This is
because the FP unit’s internal parts carry high voltages.
• To avoid fires or electrical hazards, do not modify the FP in any way.
• If metal particles, water or other types of liquids contact any of the FP unit’s internal parts,
immediately turn the unit’s power OFF, unplug the power cord, and contact your FP distributor.
• Prior to changing the FP unit’s backlight, be sure to diconnect the FP unit’s power supply.
• To prevent a possible explosion, do not install the FP in areas containing flammable gases.
• The FP 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 devices’ inherent requirements of extremely high levels of
safety and reliability.
• When using the FP with transportation vehicles (trains, cars and ships), disaster and crime
prevention devices, various types of safety equipment, non-life support related medical de-
vices, etc. redundant and/or fail-safe system designs should be used to ensure the proper
degree of reliability and safety.
•
Do not use the FP 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
.
