Service Environment

● The ambient air temperature shall not exceed + 40 ℃, and the average temperature within 24h shall not exceed + 35 ℃.

● The lower limit of ambient air temperature is - 5 ℃.

● For indoor installation and use, the altitude of the place of use shall not exceed 2000m.

● The air shall be clean. When the maximum temperature is + 40 ℃, the relative humidity shall not exceed 50%; Higher relative humidity is allowed at lower temperatures. For example, the relative humidity is 90% at + 20 ℃, but considering the change of temperature, moderate condensation may occur occasionally.

● During installation, the inclination with the vertical plane shall not exceed 5 °.

● The device is suitable for the transportation and storage process of the following temperatures: - 25 ℃ - + 55 ℃, up to 70 ℃ in a short time (no more than 24h). Under these limit temperatures, the device shall not suffer any irreparable damage, and shall be able to work normally under normal conditions.

● The device shall be installed where there is no violent vibration and impact, and where the electrical components are not enough to be corroded.

● If the above service conditions cannot be met, the user shall negotiate with the company.
