1. Brief introduction  
1.1 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  
modulated by an isolation transformer and then power 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. This manual is applicable to the following models:  
1) The DX 6000L is a standard model with inbuilt battery,  
hereinafter called 6000L;  
2) The DX 6000LXL is a long backup time model, which is able to  
connect with the external battery bank, hereinafter called  
6000LXL;  
3) The DX 10000L is a standard model with inbuilt battery, hereinafter  
called 10000L;  
4) The DX 10000LXL is a long backup time model, which is able to  
connect with the external battery bank, hereinafter called  
10000LXL;

Open the terminal block cover located on the rear panel of  
the UPS, please refer to the appearance diagram.  
For 6000L(XL) UPS, it is recommended to select the  
UL101510AWG(6mm2) wire or other insulated wire which  
complies with AWG Standard for the UPS input and output  
wirings.  
For 10000L(XL) UPS, it is recommended to select the  
UL1015 8AWG(10mm2) wire or other insulated wire which  
complies 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 UPSs  
maximum input current. Otherwise the receptacle may be  
burned and destroyed.  
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

To connect the load with the UPS, please turn off all the loads  
first, then perform the connection and finally turn on the loads  
one by one.  
No matter the UPS is connected to the utility power or not,  
the 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.  
Suggest charging the batteries for 8 hours before use. After  
connection, turn the bypass breaker in the ONposition, 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.  
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.

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 back time, it is possible to  
connect multi-battery packs, but the principle of same voltage,  
same typeshould be strictly followed.  
2. The connector of the external battery cable is used to plug into  
the external battery socket of the UPS, the other end of the  
external battery cable is made of three open wires with ring  
terminals to connect with the external battery pack(s). The  
procedure of installing battery bank should be complied with  
strictly. Otherwise you may encounter the hazardous of electric  
shock.

2.4 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.  
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.  
Note: The requirement of the output wiring is as follows:  
When the distance between the UPSs in parallel and the breaker  
panel is less than 20 meters, the difference between the wires of  
input & output of the UPSs is required to be less than 20%;  
When the distance between the UPSs in parallel and the breaker  
panel is greater than 20 meters, the difference between the wires  
of input & output of the UPSs is required to be less than 10%.

3. Parallel operation  
To perform the general operation, follow the stand-alone operating  
requirement:  
1) Startup: The units transfer to INV mode simultaneously as they  
start up sequentially in utility power mode;  
2) Shutdown: the units shut down sequentially in INV mode. When  
the l ast one completes the shutdown action, each unit will shut  
down the inverter simultaneously and transfer to bypass mode.  
It is easy to operate the equipment, with no previous training. You  
just need to read through this manual and operate according to the  
instructions in it. The meaning of the LED indicators, please refer to  
the appendix 1 Display panel”

4. 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 overdischarging.  
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.  
19

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.  
5. Notes for battery disposal and battery  
replacement  
1) Before disposing of batteries, remove conductive jewelry  
such as necklace, wrist watches and rings.  
2) If it is necessary to replace any connection cables, please  
purchase the original materials from the authorized  
distributors or service centers, so as to avoid overheat or  
spark resulting in fire due to insufficient capacity.  
3) Do not dispose of batteries or battery packs in a fire, or they  
may explode.  
4) Do not open or mutilate batteries, released electrolyte is  
highly poisonous and harmful to the skin and eyes.  
5) Do not short the positive and negative of the battery  
electrode, otherwise, it may result in electric shock or fire.  
6) Make sure that there is no voltage before touching the  
batteries. The battery circuit is not isolated from the input  
potential circuit. There may be hazardous voltage between  
the battery terminals and the ground.  
7) Even though the input breaker is disconnected, the  
components inside the UPS are still connected with the  
batteries, and there are potential hazardous voltages.
