For a unit mounted inside an enclosure, ensure that the enclosure is designed to keep the unit within its required operating
temperature range (considering a 24-watt dissipation by the controller). This is important if the controller is mounted inside
an enclosure with other heat-producing equipment.
Ambient conditions must be within these ranges:
- Operating Temperature: -20°C to 60°C (-4°F to 140°F)
- Storage Temperature: -40°C to 85°C (-40°F to 185°F)
- Relative humidity: 5% to 95% non-condensing. Pollution Degree 2
- Supply (mains) voltage allowable voltage fluctuation: +/- 10%
Do not mount the unit:
- In an area with excessive moisture, corrosive fumes, or explosive vapors
- Where vibration or shock is likely to occur
- In a location subject to electrical noise, such as in the proximity of large electrical contactors, electrical machinery,
welding equipment, and so on
