3.4 Installation notes

• Please place the UPS in a clean, stable environment, avoid the vibration, dust, humidity, flammable gas and liquid, corrosive objects. To avoid from high room temperature, a system of room extractor fans is recommended to be installed. Optional air filters are available if the UPS operates in a dusty environment.

• The environment temperature around the UPS should keep in a range of 0°C ~40°C. If the environment temperature exceeds 40℃, the rated load capacity should be
  reduced by 12% per 5°C. The max temperature can’t be higher than 50°C.

• If the UPS is dismantled under low temperature, it might be in a condensing condition.The UPS can’t be installed unless the internal and external of the equipment is fully dry. Otherwise, there will be in danger of electric shock.

• Batteries should be mounted in an environment where the temperature is within the required specs. Temperature is a major factor in determining battery life and capacity. In a normal installation, the battery temperature is maintained between 15°C and 25°C. Keep batteries away from heat sources or main air ventilation area, etc.
  WARNING!
  Typical battery performance data are quoted for an operating temperature between 20°C and 25°C. Operating it above this range will reduce the battery life while operation below this range will reduce the battery capacity.

• Should the equipment not be installed immediately it must be stored in a room so as to protect it against excessive humidity and or heat sources.
  CAUTION!
  An unused battery must be recharged every 3months. Temporarily connecting the UPS to a suitable AC supply and activating it for the time required for recharging the batteries are required.

• The highest altitude that UPS may work normally with full load is 1500 meters.
  The load capacity should be reduced when this UPS is installed in place whose altitude is higher than 1500 meters, shown as the following table:

(Load coefficient equals max load in high altitude place divided by nominal power of the UPS)

To get the UPS completely monitored by the software, you just simply connect RS232 or USB cable to each end of the computer and the UPS respectively.
