Regular service conditions
Ambient temperature:-5°C-- +40°C,daily average temperature <=+35°C, reduced capacity to run according to the actual situation.
Altitude:<=2000m
Humidity: Temparature as + 40°C,humidity not exceed 50%, a larger relative humidity is allowed at a low temperature (such as + 20°C to 90%),and temperature changes should be considered as it may cause condenssation.
Installation requirements:Ground lean gradient should be 5°or lower, and the entire Cabinet column relative flat.
Switching equipment should be installed in non-violent vibration and shock and electrical components should not be corroded by the place.
