• Relative humidity exceeding a range of 35% to 85%.
• Corrosive or inflammable gasses.
• Strong magnetism.
• Excessive dust, salt, or iron dust.
• Direct vibration or shock.
• Direct sunlight.
• Spray from water, oil, or chemicals (the front panel is basically drip-proof).
PTs with LCD display have a field of vision of 20° up, 30° down, and 30° right
and left. Install the Terminal at a height and direction that make it easy for the
operator to see.
The ambient operating temperature range is 5°C to 40°C for liquid crystal
display PTs and 0°C to 50°C for EL display PTs. Take the following factors
into consideration.
• Leave sufficient ventilation space.
• Do not install directly above machinery that puts out a lot of heat (e.g.,
heaters, transformers, high-capacity resistors).
• If the ambient temperature of a PT with LCD display rises above 40%C or
that of a PT with EL display rises above 50%C, set up a fan or air condition-
