•
Do not turn OFF the power supply to the PT while downloading or up-
loading screen data or system programming. The screen data and
system programming may become corrupted.
•
Secure the PT's cable at the control panel when connecting it to the control panel.
•
Be sure not to trip over the cable when moving around while holding the PT.
•
Use safety circuits that are capable of detecting shorts in the emer-
gency stop switch and enable switch.
•
When using the NSH5, use the lefthand belt or use a commercially avail-
able neck strap. If the NSH5 falls, injury or device damage may occur.
•
Periodically inspect for loose cables or other cable problems.
•
Confirm the safety of the system before turning ON or OFF the power
supply or before pressing the reset button.
•
After changing the settings of the DIP switch, always turn the power
supply OFF and ON or reset the PT.
•
Do not operate a touch switch using a screwdriver or other tool.
•
To ensure safety when using numeral input functions, set the upper and
lower limits for the input value.
•
Dispose of any battery that has been dropped on the floor or otherwise
subjected to excessive shock. The battery may leak if it is used.
•
Commercially available USB hubs and the recommended USB hub do
not necessarily have the same general specifications as the NSH5, and
may not function properly if used in environments subject to static elec-
tricity or other forms of noise. When using a USB hub, take sufficient
measures to prevent static electricity and other forms of noise, or do
not install the PT in an environment subject to such noise.
•
Do not disassemble or short-circuit the battery.
•
The backlight in the PT cannot be replaced by the user. Contact your
OMRON representative for backlight replacement.
•
Periodically check the installation conditions in applications where the
PT is subject to contact with oil or water.
•
Water and oil resistance will be lost if the front sheet is torn or is peel-
ing off. Do not use the PT if the front sheet is torn or is peeling off.
•
The Rubber Packing will deteriorate, shrink, expand, or harden depending on
the operating environment. Inspect and replace the Rubber Packing periodically.
•
If the brightness of the backlight on the PT is reduced, the display and RUN in-
dicator may be very dark. Do not reduce the brightness of the backlight so far
that the display and RUN indicator cannot be seen. (This applies to lot numbers
3073 and later.)
Operating Environment Precautions
•
Do not install the PT in any of the following locations:
⋅
Locations subject to rapid changes in temperature
⋅
Locations subject to temperatures or humidity outside the range
specified in the specifications
⋅
Locations subject to condensation as a result of high humidity
⋅
Locations subject to splashing chemicals or solvents
⋅
Locations subject to oil splashes
⋅
Locations subject to corrosive or flammable gases
⋅
Locations subject to strong shock or vibration
⋅
Locations outdoors subject to direct wind and rain
⋅

⋅
Locations subject to dust
⋅
Locations subject to direct sunlight
•
Take appropriate and sufficient countermeasures when installing sys-
tems in the following locations:
⋅
Locations subject to static electricity or other forms of noise
⋅
Locations subject to strong electromagnetic or magnetic fields
⋅
Locations close to power supply lines
⋅
Locations subject to possible exposure to radioactivity

1.
Waterproof cable clamps are attached to both ends of the Special
Cable. The cable has inner and outer waterproof packing. The
packing is important to maintain the cables waterproof capabilities,
so be sure it is not lost or damaged.
