3.5 Installation notes
Note: Consider for 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 environment, far away from vibration, dust, humidity, flammable gas
and liquid, corrosive. To avoid from high room temperature, a system of air extractor fans is
recommended to be installed in the room. 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 max
temperature allowable is 50℃.
◆If the UPS is unpacked 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 a risk of
electrical 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.
WARNING!
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)

◆UPS Output
Any external distribution board used for load distribution shall be fitted with protective devices that
may avoid the risk of UPS overloaded.
◆Overcurrent
Protection device shall be installed at the distribution panel of the incoming main supply. It may identify
the power cables current capacity as well as the overload capacity of the system.
WARNING!
On AC input/output, please select a thermo magnetic circuit-breaker with an IEC 60947-2 trip
curve C (normal) for 125% of the current.
3.7 Power Cables
◆The cable design shall comply with the voltages and currents provided in this section, Kindly
follow local wiring practices and take into consideration the environmental conditions
(temperature and physical support media).
WARNING!
BEFORE START-UP THE SYSTEM, PLEASE ENSURE THAT YOU ARE AWARE OF THE
LOCATION AND OPERATION OF THE EXTERNAL ISOLATORS WHICH ARE CONNECTED
TO THE UPS INPUT/BYPASS SUPPLY OF THE MAINS DISTRIBUTION PANEL.CHECK TO
SEE IF THESE SUPPLIES ARE ELECTRICALLY ISOLATED, AND POST ANY NECESSARY
WARNING SIGNS TO PREVENT ANY WRONG OPERATION.
