Safety Precautions
xvi
S Direct exposure to wind and rain (outdoor sites)
S Strong ultra-violet irradiation
Take adequate measures to ensure shielding if the NT20S is used at a location
subject to any of the following conditions.
S Static electricity, or noise from other equipment
S Strong electric or magnetic fields
S Nearby power cables
S Potential exposure to radioactivity
S Do not install at a site exposed to chemicals, steam, etc, or subject to excessive
airborne dust.
S Do not install the unit at locations where the ambient temperature goes outside
the range 0 to 50_C or where the relative humidity goes outside the range 35 to
85% RH.
If the ambient temperature exceeds the range indicated above, install a fan or
an air conditioner.
S Do not install the unit directly above equipment that generates a lot of heat
(heaters, transformers, large capacity resistors, etc.)
S Take the following points into account in order to prevent noise
(1) Avoid installing the unit in panels in which high-voltage equipment is
also installed.
(2) Install the unit at a distance of at least 200 mm from power lines.
(3) If the unit is installed next to equipment that generates a strong electric
or magnetic field (solenoids, etc.), provide a gap of at least 40 mm.
S Secure sufficient space for ventilation.
S Do not install in sites subject to severe vibration or strong shocks.
S Install at a distance from high-voltage devices and power equipment in consid-
eration of operability and safety during maintenance.
S Press touch switches with a force of no greater than 30 N.
S If touch switches are pressed in rapid succession, their inputs may not be suc-
cessfully received.
Confirm that the input of a touch switch has been successfully received before
moving on to the next operation.
S Do not press touch switches carelessly while the backlight is off or while noth-
ing is displayed on the screen. Otherwise the system may operate unpredict-
ably.
Only press touch switches after confirming system safety.
Confirm system safety carefully before changing monitor data.
