1.Briefintroduction
1.1 System and model description
The On-Line-Series is an uninterruptible power supply incorporating
double-converter technology. It provides perfect protection specifically for
strict load. The double-converter principle eliminates all mains power
disturbances. A rectifier converts the alternating current from the socket
outlet to direct current. This direct current charges the batteries and powers
the inverter. In the event of power failure, the maintenance-free batteries
power the inverter. Thus the inverter generates a sine wave AC power,
which permanently supplies the loads.
Designed with the proven on-line, double conversion architecture, this
series of UPS offers the greatest degree of availability in power protection
and provides continuous high-quality AC power to connect strict load,
especially for the basic equipments in some areas as: finance,
communication, government, traffic, manufacture, education and so on.

3.2.1 Notes for installation
1) The UPS must be installed in a location with good ventilation, far away
from water, inflammable gas and corrosive agents.
2) The UPS should not be tilted. The air inlet port at the lower part of the
front panel and the fan outlet port on the rear panel should not be
blocked so as to ensure good ventilation (Allow at least 0.5m of space on
each side).
3) In case if the UPS is unpacked, installed and used at very low
temperatures, condensation of water drops may appear. It is necessary
to wait until the UPS is fully dried inside out before proceeding to
installation and use. Otherwise, there may be a risk of electric shock.
3.2.2 Installation
Installation and wiring must be performed in accordance with the local
electric code and the following instructions by professional personnel. For
safety, please cut off the mains power breaker before installation. The
battery breaker also needs to be cut off if it is a long backup time model.
1) Open the terminal block cover located on the rear panel of the UPS
(please refer to the appearance diagram).
2) For 6K(L) UPS, it is recommended to select the UL1015 10AWG (6mm 2)
wire or other insulated wire which complies with AWG Standard for
the UPS input and output wirings.

10
3.Installation
3) For 10K(L)/31 10KL UPS, it is recommended to select the UL1015
8AWG (10 mm2) wire or other insulated wire which complies with
AWG Standard for the UPS input and output wirings.
4) For 31 12KL/31 15KL/31 20KL UPS, 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.
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.
(Please refer to section 1.4)
5) 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.
6) The protective earth ground wire refers to the wire connection between
the equipment which consumes electro-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.
7) After having completed the installation, make sure the wiring is correct.
8) Please install the leak current protective breaker at the output power
distribution panel of the UPS if necessary.
9) 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.
10) 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.
11) Suggest charging the batteries for 8 hours before use. After connection,
turn the input 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
3.Installation
12) 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) Set the battery pack breaker in “OFF” position and connect the 16
pieces of batteries in series.
3.3.3 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 input breaker in the “ON” position.
The UPS begins to charge the battery packs at the time.
3.4 Parallel operation
3.4.1 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 required, N+X is the
optimal mode. As long as the UPS is equipped with parallel cables, up to 3
of them can be connected in parallel to realize output power sharing and
power redundancy.
3.4.2 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.

13
3.Installation
3) Connect the output wires of each UPS to an output breaker panel first,
and then connect the wiring to the load via the breaker panel.
4) The parallel UPS must be equipped with battery individually.
5) Please refer the figure followed to see the wiring of parallel operation.
The capacity of the breaker must be not less than the specification as
follow.
