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 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.

output wirings.
3)
For 15000HXL31/20000HXL31, it is recommended to select the UL1015
6AWG(25mm2) wire or other insulated wire which complies with AWG Standard
for the UPS input and output wirings.
--5--
2. Installation
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.
4)
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
5)
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 protective earth ground wire should be at least as above mentioned
for each model and green wire or green wire with yellow ribbon wire is used.
6)
After having completed the installation, make sure the wiring is correct.

9)
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.
10) 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.
11) 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
backup 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) 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 10000HXL31 in parallel with blue and
brown wires; the negative pole of the battery is connected to the 10000HXL31 in
parallel with black and white wires; the green and yellow ribbon wire is connected to
the ground of the battery cabinet. For 15000HXL31/20000HXL31, the connection of
battery wire is the same as that of input and output wire, and a green or green and
2
yellow ribbon wire UL1015 6AWG (25mm ) must be connected between the input
protective earth terminal and 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.
Strictly follow the stand-alone wiring requirement to perform the input wiring of each
UPS.
Connect the output wires of each UPS to an output breaker panel.
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.
2)
3)
4)
*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.

2)
Operation and maintenance
To perform the general operation, follow the stand-alone operating requirement;
Startup: The units transfer to INV mode simultaneously as they start up sequentially
in utility power mode;
Shutdown: the units shut down sequentially
in INV mode. When the last one completes
the shutdown action, each unit will shut down
the inverter simultaneously and transfer to
bypass mode.

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.

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, 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. Therefore,
before any maintenance and repairs work is carried out, switch off the breaker of the
battery pack or disconnect the jumper wire of connecting between the batteries.
8) Batteries contain hazardous voltage and current. Battery maintenance such as the
battery replacement must be carried out by qualified personnel who are knowledgeable
