3.4 Installation notes
Note: Considering the convenience of operation and maintenance, the space in front and back of the cabinet
should be left at least 100cm and 80cm respectively when installing the cabinet.
Please place the UPS in a clean, stable environment, avoid the vibration, dust, humidity, flammable gas and
•
liquid, corrosive. 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 UPS should be in a range of 0°C～40°C. If the environment temperature
•
exceeds 40°C, 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, this might result in 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.
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.
An unused battery must be recharged every 6 months, temporarily connecting the UPS to a suitable AC supply
mains and activating it for the time required for recharging the batteries.
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)
Altitude (m)
Load coefficient
The UPS cooling is dependent on fan, so it should be kept in good air ventilated area. There are many
•
ventilation holes on the front and rear, and these should not be blocked by any obstacles.
