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, 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:
（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.

3.6 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.
3.7 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！
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 .
◆For future expansion purpose, it is economical to install power cable according to the full rating
capacity initially. The diameter of cable is shown bellow：

CAUTION!
Protective earth cable: Connect each cabinet to the main ground
system. For Grounding connection, follow the shortest route
possible。
WARNING!
Failure to follow adequate earthing procedures may result in
electromagnetic interference or in hazards involving electric shock
and fire

3.8 Power cable connect
Once the equipment has been finally positioned and secured, connect the power cables as
described in the following procedure.
Verify the UPS is totally isolated from its external power source and also all power isolators of the
UPS are open. Check to see if they are electrically isolated, and post any necessary warning signs to
prevent their inadvertent operation .
Remove the cover of terminals for wiring easily.
Terminal sequence from left to right: Input phase A(L1), input phase B(L2), input phase
C(L3), input Neutral line, output phase A(L1), output phase B(L2), output phase C(L3), output
Neutral line, battery positive, battery Neutral, battery negative. There are 3 connectors of
GROUND under the terminal block.
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.

3.9 Battery connection
The UPS adopts positive and negative double battery framework, totally 16pcs(optional 18/20) in
series. A neutral cable is retrieved from the joint between the cathode of the 8th (9th/10 th) and the
anode of the 9th (10th/11 th) of the batteries. Then the neutral cable, the battery Positive and the
battery negative are connected with the UPS respectively. The battery sets between the Battery
anode and the neutral are called positive batteries and that between neutral and cathode are called
negative ones. The user can choose the capacity and the numbers of the batteries according to their
desire.
External battery connections for long-run units.
Note：
The BAT+ of the UPS connect poles is connected to the anode of the positive
battery, the BAT-N is connected to the cathode of the positive battery and the anode
of the negative battery, the BAT- is connected to the cathode of the negative battery。
Factory setting of the long-run unit is battery quantity---16pcs, battery
capacity---12V65AH(charger current 9.75A). When connecting 18/20 batteries, please
re-set desired battery quantity and its capacity after UPS starts at AC mode. Charger
current could be adjusted automatically according to battery capacity selected. All
related settings can be done through LCD panel or monitoring software
CAUTION!
Ensure correct polarity battery string series connection. i.e.
inter-tier and inter block connections are from (+) to (-)terminals.
Don’t mix batteries with different capacity or different brands, or
even mix up new and old batteries, either.
WARNING!
Ensure correct polarity of string end connections to the Battery
Circuit Breaker and from the Battery Circuit Breaker to the UPS
terminals i.e. (+) to (+) / (-) to (-) but disconnect one or more
battery cell links in each tier. Do not reconnect these links and do
not close the battery circuit breaker unless authorized by the
commissioning engineer.
