NT20S Installation Environment

When installing the PT in the operation panel, observe the following points. See also the section "Getting Starting".
S The view angle of the LCD display screen is 40_. Install it at a position and height where operators will be able to
see it well.
S Do not install at a site exposed to chemicals, steam, etc, or subject to excessive airborne dust.
Caution:
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, transform-
ers, 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
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 consideration of operabil-
ity and safety during maintenance.
S The angle of visibility of the LCD display screen is 35 degrees to left and right. Install it at a position,
Note:
height, and orientation that will make it easy for personnel to see it.
S Install the PT at a location as far as possible from personal computers, radio equipment, radios, etc. The
electromagnetic waves generated by the PT will cause radio interference.
S When using the RS-232C +5V output, check the current capacity of the connected equipment. The maxi-
mum current value of the NT20S +5 V output is 150 mA.
Transportation and Storage of the PT
Note on transportation
Pack the PT in the packaging intended for it before transporting it.
Note on storage
Maintain the storage ambient temperature (-20 to 70 _C) and storage ambient humidity (35 to 85% RH).
