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 keep in a range of 0
℃
～
40
℃
. If the
environment temperature exceeds 40
℃
, the rated load capacity should
be reduced by 12
％
per
5
℃. The m ax temperature can't be higher than 50℃.
◆
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 6months
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)

The UPS cooling is depending on fan, so it should be kept in good air ventilation area.
There are many ventilation holes on the front and rear, so they should not be blocked by any exotic
obstacles.

External Protective Devices
For safety reasons, it is necessary to install, external circuit breaker at the input A.C. supply
and the battery. This chapter provides guidelines for qualified installers that must have the
knowledge of local wiring practices for the equipment to be installed.
