environment. The UPS must be absolutely dry before being installed. Please
allow an acclimatization time of at least two hours.

 Do not install the UPS near water or in damp environment.
 Do notinstall the UPS where it would be exposed to direct sunlight or near heat.
 Do not connect appliances or items of equipment which would overload the

UPS (e.g. laser printers, etc.) to the UPS output.

 Do not block ventilation openings in the UPS’s housing. Ensure allow at least

0.5m of space on front and rear of the UPS.

 Connect UPS with the earth reliably before connecting to the building wiring

terminal, and external battery source must also be earthed.

 An integral single emergency switching device which prevents further supply to

the load by the UPS in any mode of operation should be provided in the building
wiring installation.

 An appropriate disconnect device as short-circuit backup protection should be

provided in the building wiring installation.

 The equipment is powered by two sources: the mains source, the internal

battery or the external battery source.

 With the installation of the equipment, the sum of the leakage current of the UPS

and the connected load does not exceed 5% of rated value of input current.

1.2. Operation

 Do not disconnect the main cable on the UPS or the building wiring terminals

during operation since this would remove the protective earth from the UPS and
all connected loads.

 The UPS output terminal block may still be electrically lived from internal current

3. Introduction

This On-Line series is an uninterruptible power supply
incorporatingdouble-converter technology. It provides perfect protection
specificallyfor computer equipment, 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 invertergenerates an AC sinusoidal voltage, which
constantly supplies theloads. In the event of power failure, the maintenance-free
batteriespower the inverter.
This manual covers the UPS listed as follows. Please confirm whetherit is the
model you intend to purchase by performing a visual inspectionof the Model No. on
the rear panel of the UPS.

voltage after turning off the UPS. To make the UPS without output, turn off the
UPS, and cut off the mains power supply, wait the UPS shut down completely,
finally remove the battery connection.

3) Open the terminal block cover located on the rear panel of UPS; please refer

to the appearancediagram.

4) For 6000(XL), 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 10000(XL), 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.

10

Fig.4-2 Input and output Terminal Block wiring diagram

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. 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

connectedcorrectly and tightly.

13) It is recommendedto charge 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) Please note that the start-up power consumption of theinductance load is large,

it may cause the UPS to fail easily. Therefore, if it is necessary to connect the
inductance load such as a laser printer to the UPS, the start-up power should
be used for calculating the capacity of the UPS.

11

4.2. External Battery PackInstallation

1. The nominal DC voltage of external batterypack is 192Vdc. To achieve longer
backup time, it is possibletoconnect multi-battery packs, but the principle of
"same voltage,same type"should be strictly followed.

2. For OLS6000ECXL, select the UL1015 10AWG (6mm²)respectively or
otherinsulated wire which complies with AWG Standard for the UPSbattery
wirings.

3. For OLS10000ECXL, select the UL10158AWG (10mm²)respectively or
otherinsulated wire which complies with AWG Standard for the UPSbattery
wirings.

4. The external battery pack must be independent for each UPS. It isforbidden
that two UPS use one external battery pack.

5. The installation step of battery pack should be complied with strictly. Otherwise,
it may encounter the hazard of electric shock.

1) Ensure the UPS is not powered on and the mains input breaker is set at the

"OFF"position.

2) A DC breaker must be installed between the external batterypack and the

UPS. The capacity of breaker must be not lessthan the data specified in the
general specification.

3) Set the external battery pack breaker at"OFF"position andconnect the

16pieces 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 at the "ON" position.

6) Set the mains input breaker at the "ON" position, the UPSwould power on

and start to charge the battery pack.

4.3. 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).
