 Installation Requirement
• For easier maintenance, operation, and improved ventilation, be sure to install the ST at least 100 mm
[3.94 in.] away from adjacent structures and other equipment.
• Be sure that the ambient operation temperature and the ambient humidity are within their designated
ranges. (Ambient operation temperature: 0 to 50°C, Ambient humidity: 10 to 90%RH, Wet bulb
temperature: 39°C max.) When installing the ST on the panel of a cabinet or enclosure, “Ambient
operation temperature” indicates both the panel face and cabinet or enclosure’s internal temperature.
• Be sure that heat from surrounding equipment does not cause the ST to exceed its standard operating
temperature.
