Using the environment conditions
Ambient air humidity: cap + 40 ºC, lower limit - 15 ° ºC
Altitude: < 1000 m (if need higher elevation, the rated insulation level increase)
Needs: amplitude, intensity of no more than 8 degrees
Air relative humidity, average no greater than 95%, the monthly average no greater than 90%
No fire and explosion danger, serious pollution, chemical corrosion and the site of violent vibration
