3. Introduction
3.1 System and model description
This Online Series is an uninterruptible power supply incorporating
double-conversion technology. It provides perfect protection
specifically for computer equipment, communication systems to
computerized instruments.
Its true online double-conversion design eliminates all mains power
disturbances. A rectifier converts the alternating current from the
utility power to direct current. This direct current charges the
batteries and powers the inverter. On the basis of this DC voltage,
the inverter generates a pure sinusoidal AC voltage, which is
constantly powering the loads.
Computers and Peripherals are thus powered entirely by the UPS. In
the event of power failure, the maintenance-free batteries power the
inverter.

far away from water, inflammable gas and corrosive agents.
2) Ensure the air vents on the front and rear of the UPS are not
blocked. Allow at least 0.5m of space on each side.
3) Condensation to water drops may occur if the UPS is unpacked
in a very low temperature environment. In this case it is
necessary to wait until the UPS is fully dried inside out before
proceeding installation and use. Otherwise there are hazards of
electric shock.
The system may be installed and wired only by qualifie
d
electricians in accordance with applicable safety regulations!
-１３-
2. Installation
Installation and wiring must be performed in accordance with the local
electric code and the following instructions by professional personnel.
For safety, please cut off the mains power switch before installation.
The battery breaker also needs to be cut off if it is a long backup time
model (“ XL” model).
1) Open the terminal block cover located on the rear panel of the
UPS, please refer to the appearance diagram.
2) For UPS, it is recommended to select the UL1015
10AWG(6mm2) wire or other insulated wire which complies
with AWG Standard for the UPS input and output wirings.
3) For UPS, it is recommended to
select the
UL1015 8AWG(10mm
2
)
wire or other insulated
wire which
complies with AWG Standard for the UPS
input
and
output
wirings.
4) For
UPS, it is recommended
to select
the
UL1015 6AWG(25mm
2
)
wire or other ins
ulated wire
which
com lies with AWG Standard for the UPS
input and
output
wirings.
Note: Do not use the wall receptacle as the input power source for
the UPS, as its rated current is less than the UPS’s maximum
input current. Otherwise the receptacle may be burned and
destroyed.
5) Connect the input and output wires to the corresponding input
and output terminals according to the following diagram.
Note: you must make sure that the input and output wires and the
input and output terminals are connected tightly.

output of the UPS may have electricity. The parts inside the
unit may still have hazardous voltage after turning off the UPS.
To make the UPS have no output, power off the UPS, and then
disconnect the utility power supply.
11) Suggest charging the batteries for 8 hours before use. After
connection, turn the input breaker in the “ON” position, the
UPS will charge the batteries automatically. You can also use
the UPS immediately without charging the batteries first, but
the backup time may be less than the standard value.
12) If it is necessary to connect the inductance load such as a
monitor or a laser printer to the UPS, the start-up power should
be used for calculating the capacity of the UPS, as its start-up
power consumption is too big when it is started.
Important notes: If the UPS is used in single mode, JPI and JP2
must be connected by 10AWG(6mm2). If the UPS is used in parallel
mode, JP1 and JP2 must be disconnected.

5.3 Operating procedure for connecting the long backup
time model UPS with the external battery
1. The nominal DC voltage of external battery pack is 240VDC. Each
battery pack consists of 20 pieces of 12V maintenance free
batteries in series. To achieve longer backup time, it is possible to
connect multi-battery packs, but the principle of “same voltage,
same type” should be strictly followed.
2. For
t
he connector of the exte
batter
y
cable is used to plu ignto the external battery socket
of the UPS,
the other end of the external battery cable is m
ade
o
f
three open
wires with ring terminals to connect with the
external battery
pack(s); for ,
select the
UL1015 6AWG(25mm2)
wire or other insulated wire which compli
es
with AWG Standard
for the UPS battery wirings.
The
procedu
re of installing battery
bank should be complied with strictly.
Otherwise you may
encounter the hazardous of electric shock.
1) A DC breaker must be connected between the battery pack
and the UPS. The capacity of breaker must be not less than
the data specified in the general specification.
2) Set the battery pack breaker in “OFF” position and connect
the 20 pieces of batteries in series.
3) You must connect the external battery cable to the battery
first, if you connect the cable to the UPS first, you may
encounter the hazardous of electric shock. The positive pole
of the battery is connected to the 6KT-XL
UPS with red wire,
and
the
UPS in parallel with blue and
br
own wires
;
the negative pole of the battery
is connected to the
6K-XL UPS

3. To complete the connection by plugging the connector of the
external battery cable into the external battery socket of the UPS.
Do not attempt to connect any loads to the UPS now. You should
connect the input power wire to the right position first. And then
set the breaker of the battery pack in the “ON” position. After that
set the input breaker in the “ON” position. The UPS begins to
charge the battery packs at the time.
5.4 Parallel operation
1. Brief introduction of the redundancy
N+X is currently the most reliable power supply structure. N
represents the minimum UPS number that the total load needs; X
represents the redundant UPS number, i.e. the fault UPS number
that the system can handle simultaneously. The bigger the X is, the
higher reliability of the power system is. For occasions where
reliability is highly depended on, N+X is the optimal mode.
As long as the UPS is equipped with parallel cables, up to 3 UPSs
can be connected in parallel to realize output power sharing and
power redundancy.
The blue & brown or red wires for connection to the
positive terminal of the battery pack output
The black & white
or black
wires for connection to the
negative terminal of the
battery pack output
The green and yellow ribbon wire
for connection to the ground of
the battery cabinet
The receptacle for
connecting the UPS
-１８-
2. Parallel installation
1) Users need to opt a standard 25-pin communication cable,
which should have 25 cores, corresponding stitches and shield,
as the UPS parallel cable. The length of the parallel cable is
appropriate to be less than 3 m.
2) Strictly follow the stand-alone wiring requirement to perform the
input wiring of each UPS.
3) Connect the output wires of each UPS to an output breaker
panel.
4) Disconnect the Jumper on JP1 and JP2 of the terminal block
first, and connect each output breaker to a main output breaker
and then to the loads.
5) Each UPS need an independent battery pack.
6) Please refer to the wiring diagram in the next page, and opt
suitable breaker.
■ The requirement of the output wiring is as follows:
● When the distance between the UPS in parallel and the
breaker panel is less than 20 meters, the difference between
the wires of input & output of the UPS is required to be less
than 20%.
● When the distance between the UPS in parallel and the
breaker panel is greater than 20 meters, the difference
between the wires of input & output of the UPS is required
to be less than 10%.

turning off the UPS.
6.2 Parallel Operation
1. Parallel Machine Maintenance
This UPS system has parallel machine function, if you want to add
single machine to parallel system, please follow operational process
of joining new machine; if because of cutting down load or attainting
UPS, and you must remove UPS, please follow operational
processes of removing parallel machine.
2. How to install a new parallel UPS system:
1) Before installing a new parallel UPS system, user need to
prepare the input and output wires, the output breaker, and the
parallel cable.
2) Turn off the input and output breakers of each UPS. Connect
the input wires, output wires and battery wires. Remove the
short connection wire between JP1 and JP2 on the terminal
-２５-
block. Remove the maintenance cover board of each UPS and
set the maintenance switch from “UPS” to “BPS”.
3) Remove the cover board of the parallel port on the UPS,
connect each UPS one by one with the parallel cable, screw
the cover board of the parallel port back again.
4) Turn on the battery switch and the input breaker of the each
UPS, measure the difference voltage between the output line
wires of each UPS to check if the voltage difference between
them is less than 1V. If the difference is less than 1V, close the
output breaker. If the difference is more than 1V, check if the
wirings are abnormal.
5) Close the input breakers of all of the UPS in the parallel
system. After all of the UPS transfer to the Bypass mode,
screw the maintenance cover board back again.
6) Turn on each UPS in turn and observe their display. Make sure
that each UPS displays normal and all the UPS transfer to the
INV mode together. Measure the voltage on the JP1 and JP2
on the terminal block of each UPS to check if the voltage
difference between them is less than 1V. If the voltage
difference is more than 1V, the output relay of the UPS may not
be closed.
7) Measure the voltage of each JP2 on each UPS to check if the
voltage value is less than 5V (Generally 2V). If the difference is
more than 5V, that means the UPS needs to be regulated again
or you need to check that the parallel cable of the parallel kit
are normal.
8) Turn off each UPS in turn and after all of them transfer to the
Bypass mode, remove the maintenance cover board of each
UPS and set the maintenance switch from “BPS” to “UPS” and
screw the maintenance cover board back again.
9) Turn on the UPS in the Line mode to perform the parallel
operation.

2) Turn off the input and output breakers of the new unit. Connect
the input wires, output wires and battery wires. Remove the
short connection wire between JP1 and JP2 on the terminal
block.
3) Turn off the UPS systems that are running. After all of the
running UPS transfer to the Bypass mode, remove the
maintenance cover board of each UPS and set the
maintenance switch from “UPS” to “BPS”, then turn off the input
breaker of each UPS.
4) If the UPS system that is running is a stand-alone UPS, you
need to remove the short connection wire between JP1 and
JP2 on the terminal block.
5) Remove the cover board of the parallel port on the new UPS,
push one end of the parallel cable into the slot of the parallel kit
and screw up the connector; screw the cover board of the
parallel port back again.
6) Remove the maintenance cover board of the new UPS and set
the maintenance switch from “UPS” to “BPS”.
7) Turn on the battery switch and the input breaker of the new
UPS; measure the difference voltage between the output line
wires of new UPS and the parallel system to check if the
voltage difference between them is less than 1V. If the
difference is less than 1V, close the output breaker. If the
difference is more than 1V, check if the wirings are abnormal.
8) Remove the cover board of the parallel port located on the UPS
which has transferred to the maintenance bypass and push the
other end of the parallel cable into the slot of the parallel kit and
fasten the connector. Screw the cover board of the parallel port
back again.

9) Close the input breakers of all of the UPS (including the new
UPS) in the parallel system. After all of the UPS transfer to the
Bypass mode, screw the maintenance cover board back again.
10) Turn on each UPS in turn and observe their display. Make sure
that each UPS displays normal and all the UPSs transfer to the
INV mode together. Measure the voltage on the JP1 and JP2
on the terminal block of each UPS to check if the voltage
difference between them is less than 1V. If the voltage
difference is more than 1V, the output relay of the UPS may not
be closed.
11) Measure the voltage of each JP2 on each UPS to check if the
voltage value is less than 5V (Generally 2V). If the difference is
more than 5V, that means the new UPS needs to be regulated
again or you need to check that the parallel cable of the parallel
kit are normal.
12) Turn off each UPS in turn and after all of them transfer to the
Bypass mode, remove the maintenance cover board of each
UPS and set the maintenance switch from “BPS” to “UPS” and
screw the maintenance cover board back again.
13) Turn on the UPS in the Line mode to perform the parallel
operation.
Note: If the UPS is abnormal in the above debugging, please
perform maintenance according to the steps of removing a
stand-alone.
4. How to remove a single UPS from the parallel system:
1) If you need to remove one UPS of the UPS parallel system
which is on normal running, press the OFF button of the UPS
that is confirmed to be removed twice continuously and the
UPS will cut off its output immediately.
2) Turn off the input breaker, the external mains input breaker, the
output breaker and the battery switch of the UPS that will be
removed.

3) Press the others UPSs’s OFF button. After all of them transfer
to the Bypass mode, remove the cover board of each UPS and
set the maintenance switch from “UPS” to “BPS” and then turn
off the input breaker of each UPS.
4) After you remove one UPS, you need to connect the short
connection wire of the JP1 and JP2 located on the Terminal
block of the UPS if the remained UPS system only remain one
UPS runs by itself
5) After all panels of the UPSs do not display anything any more,
remove the cover board of the parallel port on the UPS
connected with the parallel cable of the UPS that need to be
removed. Remove the parallel cable and screw the cover board
of the parallel port back again.
6) Remove the cover board of the parallel port located on the UPS
that need to be removed and remove the parallel cable, and
then screw the cover board back again.
7) Close all of the input mains breakers of the remained UPS .
After all UPS transfer to the Bypass mode, set the UPS
maintenance switch from “BPS” to “UPS” and screw the
maintenance cover board back again. Then turn on all of the
UPSs in the Line mode to perform the parallel operation.
8) If the removed UPS will be used in a stand-alone mode, then
JP1 and JP2 on the terminal block should be connected with a
short connection wire.

7. Battery Maintenance
● This series UPS only requires minimal maintenance. The battery
used for standard models are value regulated sealed lead-acid
maintenance free battery. These models require minimal repairs.
The only requirement is to charge the UPS regularly in order to
maximize the expected life of the battery. When being connected
to the utility power, whether the UPS is turned on or not, the UPS
keeps charging the batteries and also offers the protective
function of overcharging and over-discharging.
● The UPS should be charged once every 4 to 6 months if it has
not been used for a long time.
● In the regions of hot climates, the battery should be charged and
discharged every 2 months. The standard charging time should
be at least 12 hours.
● Under normal conditions, the battery life lasts 3 to 5 years. In
case if the battery is found not in good condition, earlier
replacement should be made. Battery replacement should be
performed by qualified personnel.
● Replace batteries with the same number and same type of
batteries.
● Do not replace the battery individually. All the batteries should be
replaced at the same time following the instructions of the
battery supplier.
● Normally, the batteries should be charged and discharged once
every 4 to 6 months. Charging should begin after the UPS shuts
down automatically in the course of discharging, the standard
charging time for the standard UPS should be at least 12 hours.
