3. Introduction
This On-Line series is an uninterruptible power supply incorporating
double-converter technology. It provides perfect protection specifically
for computer equipments, communication servers, and data centers.
The double-converter principle eliminates all mains power
disturbances. A rectifier converts the alternating current from the utility
power to direct current. On the basis of this DC voltage, the inverter
generates an AC sinusoidal voltage, which constantly supplies the
loads. In the event of power failure, the maintenance-free batteries
power the inverter.
This manual covers the UPS listed as follows. Please confirm whether
it is the model you intend to purchase by performing a visual inspection
of the Model No. on the rear panel of the UPS.

(35~44 1b in)

2) No matter the UPS is connected to the utility power or not, the

output of the UPS may be electrically live. 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
cut off the utility power supply, wait the UPS shut down
completely.
3) Open the terminal block cover located on the rear panel of UPS,
please refer to the appearance diagram.
4) For 6KVA UPS, it is recommended to select the UL1015
10AWG/4mm 2 or other insulated wire which complies with AWG
Standard for the UPS input and output wirings.

5) For 10KVA UPS, it is recommended to select the UL1015

6AWG/10mm 2 or other insulated wire which complies with AWG
Standard for the UPS input and output wirings.
6) Ensure the capacity of mains power supply. 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.
7) The protective earth ground wire should be installed first
according to the following diagram. It is better to use green wire
or green wire with yellow ribbon wire.

15
 8) Connect other input and output wires to the corresponding input
and output terminals according to the following diagram.
9) It is recommended to use the accessorial terminal connectors
which can be compacted on the wires tightly, to ensure the
connection between the wires and the terminal block is reliable.

Fig. 4-6 Input and output Terminal Block wiring diagram

Important notes: If the UPS is used in single mode, JP1 and JP2
must be connected. If the UPS is used in parallel mode, the Jumper
between JP1 and JP2 must be removed.

10) Install an output breaker between the output terminal of UPS

and the load, and the breaker should with leakage current
protective function if necessary.

11) Turn off all the loads first before connecting the load with the
UPS, then perform the connection and finally turn on the loads
one by one.
12) After completing the installation, check all the wires is
connected correctly and tightly.
13) Suggest charging the batteries for 8 hours before use. After
installation, turn on the mains power switch and turn the input
breaker in the “ON” position, the UPS will charge the batteries
automatically. It can also use the UPS immediately without
charging the batteries, but the backup time may be less than the
standard value.
16
 14) 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 to make the UPS which capacity
is small fail easily.

4.4 Operating procedure for connecting 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 6KVA, select the UL1015 10AWG/4mm 2 respectively or other
insulated wire which complies with AWG Standard for the UPS
battery wirings.

3. For 10KVA, select the UL1015 6AWG/10mm2 respectively or other

insulated wire which complies with AWG Standard for the UPS
battery wirings.
4. The external battery pack must be independent for each UPS. It is
forbidden that two UPSs use same external battery pack.
5. The procedure of installing battery pack should be complied with
strictly. Otherwise it may encounter the hazardous of electric
shock.

1) Ensure the UPS is not powered on and the mains input

breaker is set in the “OFF” position.
2) A DC breaker must be installed between the external battery
pack and the UPS. The capacity of breaker must be not less
than the data specified in the general specification.

17
 3) Set the external battery pack breaker in “OFF” position and
connect the 20 pieces of batteries in series.
4) Connect the external battery pack to the battery terminals.
Check the polarity of connection is correct.
5) Set the breaker of the battery pack in the “ON” position.
6) Set the mains input breaker in the “ON” position, the UPS
would power on and start to charge the battery pack.

4.5 EPO Connection

4.5.1 Introduction
Emergency power off function which the UPS supplies is, when the
emergency occurs, such as the failure of load, the UPS can cut off
the output at once by operating the EPO port manually.
4.5.2 The connection
Normally the EPO connector is closed with a wire on the rear panel,
which is supplied in the accessory. Once the connector is open, the
UPS would stop the output and enter EPO status.

5.2.5 HE mode (High Efficiency mode)

It is also called economy mode.
After the UPS is turned on, the power used by the load is supplied
from the utility power via internal filter while the utility power is in
normal range, so the high efficiency could be gained in the HE mode.
Once the mains is loss or abnormal, the UPS would transfer to Line
mode or Battery mode and the load is supplied continuously.

Fig. 5-7 HE mode

1) The function could be enabled through the LCD setting or the
software (Winpower, etc.).

24
2) It is attention that the transfer time of UPS output from HE
mode to battery mode is about 10ms. But it is still too long for
some sensitive load.
5.2.6 Converter mode
In converter mode, the UPS would free run with fixed output
frequency (50Hz or 60Hz). Once the mains is loss or abnormal, the
UPS would transfer to battery mode and the load is supplied
continuously.

Fig. 5-8 Converter mode

1) The function could be enabled through the LCD setting or the

software (Winpower, etc.).
2) The load should be derating to 60% in converter mode.

5.2.7 Warning
When the warning occurs, it illustrates that there are some
abnormal problems during the operation of UPS. Normally the
problems are not fatal and the UPS continues working, but they
should be paid attention to, or the UPS may fail.
The detailed warning table is shown in chapter of 7.

25
 Fig. 5-9 Warning

5.2.8 Fault
When the fault occurs, it illustrates that some fatal problems
happened, the UPS would directly cut off the output or transfer to
bypass, and keep alarming. The backlight of LCD would also turn to
red.
The detailed fault table is shown in chapter of 7.

Fig. 5-10 Fault

5.2.9 Other status

When the UPS is overload, the alarm will beep twice every second.
Some unnecessary loads should be get rid of one by one to
decrease the loads connected to the UPS less than 90% of its
nominal power capacity.

26
 Fig. 5-11 Overload

While doing the battery test, LEDs would be lighted circularly, and
the symbol of battery test would be shown on the display.

Fig. 5-12 Battery test

6. Special function
The series UPS has some special functions, which could satisfy
some special application of user. And the functions have own
features, please contact your local distributor for further information
before using the function.

6.1 HE function

6.1.1 Brief introduction of HE function

If HE function is set to enable, after the UPS is turned on, the power
used by the load is directly supplied from the utility power via
internal filter while the utility power is in normal range, so the high
efficiency could be gained in HE mode. It is also called economy
mode. Once the mains is loss or abnormal, the UPS would transfer
to Line mode or Battery mode and the load is supplied continuously.
The great virtue is overall high efficiency >0.96 of UPS, to save
power for user.
But the disadvantage is 1) the load can not be protected as well as
in Line mode, for the load is directly supplied from the utility; 2) the
transfer time of UPS output from HE mode to Battery mode is about
10ms.
So the function is not suitable to some sensitive loads, and the
region where the utility power is unstable.

6.1.2 Set the function

The function could be enabled through the LCD setting in Bypass
mode.
Enter the power strategy setting menu by following chapter of 5.5.7.

40
6.2 Converter function

6.2.1 Brief introduction of Converter function

In converter mode, the UPS would free run with fixed output
frequency (50Hz or 60Hz). Once the mains is loss or abnormal, the
UPS would transfer to Battery mode and the load is supplied
continuously.
The great virtue is the output frequency is fixed, which is required by
some very sensitive loads.
But the disadvantage is the load capacity of UPS should be derating
to 60% in converter mode.
6.2.2 Set the function
The function could be enabled through the LCD setting in Bypass
mode.
Enter the power strategy setting menu by following chapter of 5.5.7.

6.3 Parallel function

6.3.1 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. When the X is larger, the
reliability of the power system is higher. 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 4 UPSs

can be connected in parallel to realize output power sharing and
power redundancy.

41
6.3.2 Parallel installation and operation
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) Users need to use 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 3m. And there is one standard
parallel cable in the accessories of every UPS.
3) Remove the cover plate of the parallel port on the UPS,
connect each UPS one by one with the parallel cable, and
re-screw the Parallel port cover which is supplied in the
accessories.
4) Strictly follow the chapter of 4, the wiring requirement of single
UPS to perform the wiring of each UPS.
5) Connect the output wires of each UPS to an output breaker
panel.
6) 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.
7) Each UPS need an independent battery pack.
8) Please refer to the wiring diagram in the following diagram.
9) The distance between the UPSs in parallel and the breaker
panel is required to be less than 20 meters. The difference
between the wires of input and output of the UPSs is required to
be less than 20%.

10) Do not switch on the output breaker of each UPS, switch on the
input breaker of the each UPS, the UPS should work in bypass
with output, observe their display to check if there are any
warning or fault information, measure the output voltage of
each UPS separately to check if the voltage difference between
them is less than 1V. If the difference is more than 1V, check
the wiring.
11) Press the button of one UPS, each UPS would start to turn
on, all the UPSs would transfer to the INV mode together.
Measure the output voltage of each UPS separately to check if
the voltage difference between them is less than 0.5V. If the
difference is more than 0.5V, the UPSs need to be regulated.
12) Press the button of one UPS, each UPS would start to turn
off and transfer to the Bypass mode, switch on the output
breaker of each UPS to parallel all the output of UPSs together.
44
13) Press the button of one UPS, each UPS would start to turn
on, after turning on, the UPSs should work parallel in the Line
mode.

How to join a new UPS to a parallel system:

1) First the parallel system must be installed one main
maintenance mechanical switch or static switch.
2) Ensure the bypass is normal and the bypass setting is “enable”,
remove the cover plate of maintenance switch on the rear panel
of each UPS, the UPS system would transfer to bypass
automatically, set the own maintenance switch of each UPS
from “UPS” to “BPS”.
3) Set the main maintenance switch or static switch from “UPS” to
“BPS”, switch off the main output breaker, and the UPSs would
shut down.
4) Ensure the UPSs shut down totally, set the UPS own
maintenance switch from “BPS” to “UPS” and screw the
maintenance cover plate back again. Reinstall the new UPS
parallel system by following step 1) to 12) of last chapter -
“install a new parallel UPS system”.
5) Set the main maintenance switch or static switch from “BPS” to
“UPS”, Press the button of one UPS, each UPS would start
to turn on, after turning on, the UPSs should work parallel in the
Line mode.

How to remove a single UPS from a parallel system:

1) First the parallel system must be installed one main
maintenance mechanical switch or static switch.
2) Ensure the bypass is normal and the bypass setting is “enable”,
remove the cover plate of maintenance switch on the rear panel
of each UPS, the UPS system would transfer to bypass
automatically, set the own maintenance switch of each UPS
from “UPS” to “BPS”.
45
3) Set the main maintenance switch or static switch from “UPS” to
“BPS”, switch off the main output breaker, and the UPSs would
shut down.
4) Ensure the UPSs shut down totally, set the UPS own
maintenance switch from “BPS” to “UPS” and screw the
maintenance cover plate back again. Remove the wanted UPS
and reinstall the new UPS parallel system by following step 1)
to 12) of last chapter - “install a new parallel UPS system”.
5) If the removed UPS or the remained 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.
6) Set the main maintenance switch or static switch from “BPS” to
“UPS”, Press the button of one UPS, each UPS would start
to turn on, after turning on, the UPSs should work parallel in the
Line mode.

8. Battery Maintenance
Battery replacement should be performed by qualified personnel.

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.

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.

If the battery service life (3~5 years at 25°C ambient
temperature) has been exceeded, the batteries must be
replaced.
