2.2.2 Battery Room
The battery will generate some amount of hydrogen and oxygen at the end of charging, so the
fresh air volume of the battery installation environment must meet EN50272-2001 requirements. The
ambient temperature of the battery must be stable. Ambient temperature is a major factor in determining
the battery capacity and life. The nominal operating temperature of battery is 20°C. Operating above this
temperature will reduce the battery life, and operation below this temperature will reduce the battery
capacity. If the average operating temperature of battery is increased from 20ºC to 30ºC, then the
service life of the battery will be reduced by 50%. If the operating temperature of the battery is above
40ºC, then the battery service life will be decreased in exponent rate. In a normal installation, the battery
temperature is maintained between 15°C and 25°C. Keep batteries away from heat sources or air
outlets.
If external batteries are to be used, a battery protection device (a DC circuit breaker) must be
mounted as close as possible to the batteries, and the connecting cables should be as short as possible.
2.2.3 Storing
If the equipment not be installed immediately, it must be stored in a room so as to protect it against
excessive humidity and heat sources. The battery needs to be stored in dry and cool place with good
ventilation. The most suitable storage temperature is 20 ºC to 25ºC.
2.3 Disassembly, Initial Checking and Positioning
Check the packaging first upon the arrival of product to see if there is any damage; open the
packaging to check the equipment; report any such damage to the shipper immediately.
2.3.1 System Packing
Open the wooden case first, then take out the foam. Be careful not to scratch the product.
Fig 2-1 UPS Packing Diagram
Tip: Dismantle the bolts that connect the cabinet and wooden pallet after disassembly, then
lift the cabinet to installation position. The dismantlement should be careful so as not to scratch
the body.
Verify the product label and confirm the correctness of the equipment. The equipment label is
attached on the back of front door. The UPS model, capacity and main parameters are marked on the
label.
