Installation
„ Installation location
Install the product in the following location that provides easy access for inspection.
• Inside an enclosure installed indoors
• Operating ambient temperature: –10 to +60 °C [+14 to +140 °F] (non-freezing)
• Operating ambient humidity: 85% or less (non-condensing)
• Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
• Area not exposed to direct sun
• Area free of excessive amount of dust, iron particles or the like
• Area not subject to splashing water (rain, water droplets), oil (oil droplets) or other liquids
• Area not subject to continuous vibration or excessive shocks
• Area free of radioactive materials, magnetic fields or vacuum
• Altitude: Up to 1000 m (3300 ft.) above sea level
• Area free of excessive electromagnetic noise (from welders, power machinery, etc.)
When using near a switching circuit or high-frequency power supply, the induced current
may flow inside the fan due to electromagnetic noise (conductive noise, radiative noise).
If the induced current flows, the electric corrosion is caused in the bearings of the fan. As
a result, it may generate the noise or shorten the service life of the products.
