Please read carefully the following user manual and the
safety instructions before installing the unit or using the
unit!

1.1 Installation

This is permanently connected equipment, and it must be
installed by qualified maintenance personnel.

Condensation may occur if the UPS is moved directly from a
cold to a warm environment. The UPS must be absolutely dry

before being installed. Please allow an acclimatization time of at

least two hours.

Do not install the UPS near water or in damp environment.

Do not install the UPS where it would be exposed to direct

sunlight or near heat.

Do not connect appliances or items of equipment which would

overload the UPS (e.g. laser printers, etc.) to the UPS output.

Place cables in such a way that no one can step on or trip over

them.

Connect UPS with the earth reliably before connecting to the

building wiring terminal, and external battery source must also

be earthed.

An integral single emergency switching device which prevents

further supply to the load by the UPS in any mode of operation

should be provided in the building wiring installation.

An appropriate disconnect device as short-circuit backup

protection should be provided in the building wiring installation.

The equipment is powered by two sources: the mains source,

the internal battery or the external battery source.

1

With the installation of the equipment, the sum of the leakage
current of the UPS and the connected load does not exceed 5%

of rated value of input current.

Do not block ventilation openings in the UPS’s housing. Ensure

allow at least 50cm of space on front and rear of the UPS.

1.2 Operation

Do not disconnect the mains cable on the UPS or the building
wiring terminals during operation since this would remove the

protective earth from the UPS and all connected loads.

The UPS output terminal block may still be electrically lived

even if the UPS is not connected to the building wiring terminal,

for there is internal current source (batteries).

In order to fully disconnect the UPS, first turn the input breaker

in the “OFF” position, then disconnect the mains lead.

Indiscriminate operation of switches may cause output loss or

damage to equipment. Refer to instruction before conducting

any control.

While the UPSs work as a parallel system, the external parallel

cable should be reinforced insulation.

Ensure that no liquid or other foreign objects can enter the UPS.

1.3 Maintenance, Servicing and Faults

Do not remove the enclosure since the UPS operates with
hazardous voltages. It is to be serviced only by qualified

maintenance personnel.

Caution - risk of electric shock. Even after the unit is

disconnected from the mains power supply (building wiring

terminal), components inside the UPS are still connected to the

battery which are potentially dangerous.

2

Before carrying out any kind of service and/or maintenance,
isolate UPS and disconnect the batteries. Verify that no current

is present and no hazardous voltage exists in the capacitor or

BUS capacitor.

Batteries must be replaced only by qualified personnel.

Batteries have a high short-circuit current and pose a risk of

shock. Take all precautionary measures specified below and

any other necessary measures when working with batteries:

remove all jewellery, wristwatches, rings and other metal

objects

use only tools with insulated grips and handles.

When changing batteries, replace with the same quantity and

the same type of batteries.

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 mains

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.

4.3.2 Installation

For safety, please cut off the mains power switch before
installation!

Use cable cross section and protective device specification

1)

It is suggested to install an external isolating device against

current backfeed between Mains input and UPS (see Fig.4-6).

After the device is installed, it must add a warning label with the

following wording or the equivalent on the external AC contactor:

RISK OF VOLTAGE BACKFEED. Isolate the UPS before

operating on this circuit, then check for hazardous voltage

between all terminals.

13

Fig.4-6 Typical external isolating device installation

2) No matter the UPS is connected to the mains 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 mains 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
8AWG/6mm2or other insulated wire which complies with AWG

Standard for the UPS input and output wirings.

5) For 8/10KVA UPS, it is recommended to select the UL1015
6AWG/10mm2or 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.

14

8) Connect other input and output wires to the corresponding input
and output terminals according to the following diagram.

9) It is requested to use the accessorial terminal splices which can
be compacted on the wires tightly, to ensure the connection

between the wires and the terminal block is reliable.

Fig. 4-7 Input and output Terminal Block wiring diagram

Notes: 1) If the UPS is used in single mode, J1 and J2 must be

connected. If the UPS is used in parallel mode, the Jumper

between J1 and J2 must be removed.

2) Battery+/- connection is only for “XL” model.

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.

15

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 (Only for “XL” model)

1.

2.

3.

4.

5.

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.

For 6KVA, select the UL1015 8AWG/6mm2respectively or other

insulated wire which complies with AWG Standard for the UPS

battery wirings.

For 8/10KVA, select the UL1015 6AWG/10mm2respectively or other

insulated wire which complies with AWG Standard for the UPS

battery wirings.

The external battery pack must be independent for each UPS. It is
forbidden that two UPSs use same external battery pack.

The procedure of installing battery pack should be complied with
strictly. Otherwise it may encounter the hazardous of electric

shock.

1)2)Ensure the UPS is not powered on and the mains input
breaker is set in the “OFF” position.

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.

16

3)

4)

5)

6)

Set the external battery pack breaker in “OFF” position and
connect the 20 pieces of batteries in series.

Connect the external battery pack to the battery terminals.
Check the polarity of connection is correct.

Set the breaker of the battery pack in the “ON” position.

Set the mains input breaker in the “ON” position, the UPS
would power on and start to charge the battery pack.

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 ECO Function

6.1.1 Brief introduction of ECO function

If ECO function is set to enable, after the UPS is turned on, the power
used by the load is directly supplied from the mains power via

internal filter while the utility power is in normal range, so the

economy mode could be gained in ECO mode. Once the mains power

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 mains; 2) the

transfer time of UPS output from ECO mode to Battery mode is about

10ms.

So the function is not suitable to some sensitive loads, and the

region where the mains 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 5.3.4

28

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 power 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 derated 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 5.3.4.

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.

6.3.2 Parallel installation and operation

How to install a new parallel UPS system:

1)

2)

3)

4)

5)

6)

7)

8)

9)

Before installing a new parallel UPS system, user need to

prepare the input and output wires, the output breaker, and the

parallel cable.

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.

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.

Strictly follow the chapter of 4, the wiring requirement of single

UPS to perform the wiring of each UPS.

Connect the output wires of each UPS to an output breaker

panel.

Disconnect the Jumper on J1 and J2 of the terminal block

first, and connect each output breaker to a main output breaker

and then to the loads.

Each UPS need an independent battery pack.

Please refer to the wiring diagram in the following diagram.

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.

32

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)

2)

3)

4)

5)

6)

First the parallel system must be installed one main

maintenance mechanical switch or static switch.

Regulate the output voltage of the new UPS separately: check

if the output voltage difference between the new UPS and the

parallel system is less than 0.5V.

Ensure the bypass of the parallel system 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”.

Set the main maintenance switch or static switch from “UPS” to

“BPS”, switch off the main output breaker and the main input

breaker, the UPSs would shut down.

Ensure the UPSs shut down totally, add the new UPS and

reinstall the new UPS parallel system by following step 1) to 9)

of last chapter - “install a new parallel UPS system”.

Switch on the main input breaker and the main output breaker,

and set the main maintenance switch or static switch from

“BPS” to “UPS”, then set the UPS own maintenance switch

from “BPS” to “UPS” and screw the maintenance cover plate

back again. 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.

6)

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”.

Set the main maintenance switch or static switch from “UPS” to

“BPS”, switch off the main output breaker and the main input

breaker, and the UPSs would shut down.

Ensure the UPSs shut down totally, remove the wanted UPS

and reinstall the new UPS parallel system by following step 1)

to 9) of last chapter - “install a new parallel UPS system”.

If the removed UPS or the remained UPS will be used in a

stand-alone mode, then J1 and J2 on the terminal block

should be connected with a short connection wire.

Switch on the main input breaker and the main output breaker,

and set the main maintenance switch or static switch from

“BPS” to “UPS”, then set the UPS own maintenance switch

from “BPS” to “UPS” and screw the maintenance cover plate

back again. 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.

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 mains 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.
