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;

installation. The battery breaker also needs to be cut off if it is a
long backup time model (“XL” model).
● 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 UPS’s
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
● The protective earth ground wire refers to the wire
connection between the equipment which consumes electric
equipment and the ground wire. The wire diameter of

● 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 “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.
● 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.

2.3 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 back time, it is possible to
connect multi-battery packs, but the principle of “same voltage,
same type” should 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.

1) 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 the10000LXL in parallel with blue and brown wires;
the negative pole of the battery is connected to the 10000LXL in
parallel with black and white wires; the green and yellow ribbon
wire is connected to the ground of the battery cabinet.
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 bypass breaker in the ON position. The UPS begins to
charge the battery packs at the time.

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”
