3.4 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, 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 max 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:

◆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.
3.5 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.
◆External Battery
The UPS and its associated batteries are protected against the effect of over-current
through a DC compatible thermo-magnetic circuit-breaker (or a set of fuses) located close to
the battery.
◆UPS Output
Any external distribution board used for load distribution shall be fitted with protective
devices that may avoid the risk of UPS overloaded.
◆Over-current
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.
CAUTION!
Select a thermo magnetic circuit-breaker with an IEC 60947-2 trip
curve C (normal) for 125% of the current as listed below.
3.6 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!
Upon starting. 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 and necessary
warning signs to prevent any inadvertent operation.

◆When selecting, connecting, and routing power cables, follow local safety regulations and
rules.
◆If external conditions such as cable layout or ambient temperatures change, perform
verification in accordance with the IEC-60364-5-52 or local regulations.
◆If the rated voltage is 400 V, multiply the currents by 0.95. If the rated voltage is 415 V,
multiply the currents by 0.92.
◆If primary loads are non-linear loads, increase the cross-sectional areas of neutral
wires1.5–1.7 times.
◆The nominal battery discharge current refers to the current of forty 12 V batteries at 480V
in standard configuration.
◆The maximum battery discharge current refers to the current when forty 12 V batteries in
standard configuration, that is, two hundred and forty 2 V battery cells (1.67 V/cell), stop
discharging.
◆The battery cable specifications are selected based on 40 batteries by default and
compatible with application scenarios with 30–50 batteries.
◆When the mains input and bypass input share a power source, configure both types of input
power cables as mains input power cables. The cables listed in Table are used only when
the following requirements are met:
−Routing mode: Routing the cables over the cable ladder or bracket in a single layer
(IEC60364-5-52 middle E).
−The ambient temperature is 30°C.
−The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
−90°C copper flexible cable.
−The length of the AC power cables of a UPS is no longer than 30 m and DC power cables
no longer than 50 m.

Warning！
In the case of “Dual input” operation, make sure the copper wire
between each input lines have been removed. The AC input and the AC
bypass supplies must be referenced to the same neutral point.
Choose appropriate power cable. (Refer to the table above) and pay attention to the
diameter of the connection terminal of the cable that should be greater than or equal to that of
the connection poles;
WARNING!
If the load equipment is not ready to accept power on the
arrival of the commissioning engineer then ensure that the system
output cables are safely isolated at their ends
Connect the safety earth and any necessary bonding earth
cables to the copper earth screw located on the floor of the
equipment below the power connections. All cabinets in the UPS
must be grounded properly.
CAUTION!
The earthing and neutral bonding arrangement must be in
accordance with local and national codes of practice.
