2. Description of Commonly Used Symbols
Some or all of the following symbols may be used in this manual. It is advisable to
familiarize yourself with them and understand their meaning:
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.

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, turn off the
UPS, and cut off the mains power supply, wait the UPS shut down completely,
finally cut off the battery connection.
3) Open the terminal block cover located on the rear panel of UPS, please refer
to the appearance diagram.
4) For 6K(L), it is recommended to select the UL1015 10AWG (6mm²) or other
insulated wire which complies with AWG Standard for the UPS input and
output wirings.
5) For 10K(L), it is recommended to select the UL1015 8AWG (10 mm²) or 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.
8) Connect other input and output wires to the corresponding input and output
terminals according to the following diagram.
Note: Make sure that the input and output wires and the input and output terminals
are connected tightly.

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.
10) Install an output breaker between the output terminal of UPS and the load, and
the breaker should be 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, please check the wires to make sure all were
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.
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.

13
4.3. External Battery Pack Connecting Procedure
1. The nominal DC voltage of external battery pack is 192Vdc. 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. For 6KL, select the UL1015 10AWG (6mm²)respectively or other insulated wire
which complies with AWG Standard for the UPS battery wirings.
3. For 10KL, select the UL1015 8AWG (10mm²)respectively or other insulated
wire which complies with AWG Standard for the UPS battery wirings.
4. The external battery pack must be independent for each UPS. It is forbidden
that two UPS use one external battery pack.
5. The procedure of installing battery pack should be complied with strictly.
Otherwise it may encounter the hazardous of electric shock.
1) Ensure the UPS is not powered on and the mains input breaker is set in the
"OFF" position.
2) 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.
3) Set the external battery pack breaker in "OFF" position and connect the 16
pieces of batteries in series.
4) Connect the external battery pack to the battery terminals. Check the
polarity of connection is correct.
5) Set breaker of the battery pack in the "ON" position.
6) Set the mains input breaker in the "ON" position, the UPS would power on
and start to charge the battery pack.
4.4. EPO Connection
EPO(Emergency power off):when the emergency occurs, such as the failure of
load, the UPS can cut off the output at once by operating the EPO port manually.
The connection
：
Normally the EPO connector is closed with a wire on the rear panel (Fig.4-4),which
is supplied in the accessory. Once the connector is open, the UPS would stop the
output and enter EPO status (Fig.4-3).
