 Installation Requirement
• For easier maintenance, operation, and improved ventilation, be sure to install the OT at least 100mm
[3.94in] 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 [-32 to 122°F], Ambient humidity: 10 to 90%RH, Wet
bulb temperature: 39°C[102°F] max.) When installing the OT 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 OT to exceed its standard operating
temperature.
