Use Of Condition
- Ambient air temperature: from -5ºC to +40ºC, and average temperature shall be not higher than +35ºC in 24h.
- Atmospheric conditions, relative humidity shall not be over 50% when the highest temperature is at +40ºC. Bu higher humidity is allowed when the temperature is lower, for instance, humidity can be 90% when +20ºC. It shall be taker into consideration that changes in temperature can accidentally cause condensation.
- Absolute elevation shall be not higher than 2000m. (Otherwise, the capacity shall be reduced)
- The temperatures for transportation and storage of this device is from +25ºC to +55ºCC, in a short time (no longer than 24h) the limiting temperature can reach +70ºC, in that case, unrecoverable damages will not occur on the device In case the above service conditions are not satisfied. the user shall consult with the manufacturer
- If this device is used in offshore oil platforms or nuclear stations, another technical agreement shall be signed.
