Operating Conditions

Environmental Temperature
The ambient air temperature shall not exceed +40°C or be below -5°C, with a 24-hour average temperature not exceeding +35°C.
Altitude
For indoor installation, the altitude of the installation site shall not exceed 2000m.
Relative Humidity
The relative humidity of the surrounding air shall not exceed 50% at the highest temperature of +40°C, but a higher relative humidity is allowed at lower temperatures (e.g., 90% at +20°C), taking into account the possible occasional formation of condensation due to temperature changes.
Installation Site
The equipment shall be installed with a tilt of no more than 5° from the vertical. 
The equipment shall be installed in locations free from severe vibration and shock, as well as from any corrosive substances that could affect the electrical components. 
For special requirements, the user may consult the manufacturer for resolution.
