Shenzhen Santak UPS power supply of the host to the ambient temperature is not high, the work, the ambient temperature is 0-40 degrees, the humidity is 10%-90%. Santak UPS power supply in the room should avoid direct sunlight, and leave enough room for ventilation, the working environment of Santak UPS power should be kept clean, in order to avoid harmful dust on the Santak UPS power supply internal corrosion. Otherwise, the dust and moisture will cause the host to work is not normal. Battery temperature requirements are higher, the standard temperature of 25 degrees Celsius, usually can not exceed the range of 15-30 degrees celsius. The temperature is too low, the battery capacity will drop, the temperature dropped by 1 degrees Celsius, the capacity decreased by 1/1000. Its discharge capacity will increase with the increase of temperature, and its service life is reduced.
