product Environment

Ambient temperature: -5 ℃ ~ + 40 ℃, and the average temperature within 24h not exceed + 35 ℃.
Altitude: not exceed 2000m.
The ambient air temperature of + 40 ℃ not more than 50%; at lower temperaturescan have a higher relative humidity on (eg: + 20 ℃ at 90%), taking into account the change in temperature allows the generation of a moderate condensation.
Equipment installation and the vertical gradient should not exceed 5 °
Equipment should be installed in the absence of severe vibration, shock-free and corrosion-freeplace
Note: More than the above conditions can be negotiated with the company
