I. INTRODUCTION
1.1 System Description
XC Series Uninterruptible Power Supplies are advanced true On-Line Sinewave UPS with static
transfer switch which provide reliable, regulated, transient-free AC power to sensitive equipment,
ranging from computers, telecommunication systems to computerized instruments.
Because the UPS is a true On-Line system, conditioned power is provided continuously to the
connected equipments. Unlike standby power systems, the UPS is constantly regulating and
filtering the output power. When incoming power is interrupted, the UPS protects the computers
instantaneously without any transfer time.
The XC Series has high nonlinear load capability (i.e. Crest Ratio 3:1) and this is suitable for
powering special loads such as switching power supplies or highly capacitive inputs.
The system's static transfer switch (S.T.S) provides by-pass power as its standby source. During
an overload condition, the S.T.S will switch the customer's load over to the bypass line with no
interruption. The S.T.S will transfer back to the inverter automatically when the overload condition
has been cleared. If the inverter fails internally, the unit switches to bypass within milliseconds.
To choose the XC Series as your equipment protector was a wise investment.
It includes many features to protect your critical equipments:
Full Protection
- Built-in battery to protect from power outage
- S.T.S to protect when UPS fails
- On line operation to condition output continuously
- Sinewave output waveform
High Nonlinear Load Capacity
- Special for Computers
Easy operation and installation.

II. SETTING UP THE UPS
2.1 Unpacking
The UPS is packed and enclosed in a structural cardboard carton to protect it from danger.
1. Inspect for damage that may have occurred during the shipment If any damage is
noted, call the shipper immediately and retain the shipping carton and the UPS.
2. Carefully open the carton and take the UPS out.
3. Retain the carton and packing material for future use.
2.2 Location Selection
The UPS is designed to be installed in a protected environment. The following conditions should be
prohibited.
1. Blocking the airflow intake and outlet. (It is recomended to retain 10 cm.(4 in.)
between the rear side and the wall.)
2. Environment temperature and humidity out of specification.
3. Location subject to excessive moisture, dust and corrosion.
4. Location exposed to heat source or direct sunlight.
2.3 Installation
It is recomended that the UPS should be connected to a dedicated outlet protected by a circuit
breaker. The UPS has a built in power cord with a ground and 2 receptacles on the rear panel.
1. Make sure that the on-off switch the rear panel is in the "0" position.
2. Plug in the input power cord to a wall outlet.
3. If the “Reverse Line Polarity Indicator” is on, reverse the AC input phase and neutral lines.
4. Turn on the On-Off Switch, into “1” on position.
WARNING : DO NOT DEFEAT GROUND CONNECTIONS

2.4 Start-Up
1. Turn on the on-off switch on the rear panel to "1" .
2. The red LED indicator "BYPASS" should light on.
3. In a few seconds the cooling fan will start to operate, then the "BYPASS” indicator will be off
and the green LED indicator "UPS" will turn on and will start to give the UPS power to the
output.
4. Disconnect the input power cord from the power outlet. The "LINE FAILURE" will appear on
the LCD panel and audible alarm will sound intermittently. Now the load is supplied from the
battery source.
5. Plug in the power cord again and see that "LINE FAILURE"alarm is off.
6. Now your UPS is ready to operate. Plug in the critical loads to the output receptacles of the
unit.
NOTE
If any condition is different from the above situation, call our local service representative for
assistance.
CAUTION
After initial start-up, keep power continuously to the unit for at least 8 hours to ensure that the
batteries are fully charged.

III. OPERATION PROCEDURE
3.1 Turn On procedure
1 . Turn On the PK1 on-off switch on the rear panel to "I" position.
2 . Turn on the power switches on your critical load after the "UPS" indicator will light on.
3.2 Turn Off procedure
1. Turn off all the power switches on your critical equipments that are connected to the UPS.
2. Turn Off the PK1 on-off switch on the rear panel to "0" position.
CAUTION
A . The UPS charges its battery whenever it is connected to utility power.
B . For daily TURN ON / TURN OFF operation , it is recommended to keep the on to ensure
proper battery operation.
WARNING:
When the UPS connected to utility power, the line power will be supplied to output receptacles
directly. DO NOT insert objects other than equipment power cords into outlets.
3.3 When utility power is interrupted
In case the utility power is interrupted, the UPS converts the built-in battery source to output
receptacles immediately to protect your critical loads from loss of data or damage. Battery
back-up time is 10 minutes for full load and can be extended by removing non-critical loads.
After an utility power blackout, the audible alarm and "LINE FAILURE "will appear on the LCD
panel. When the "BATTERY LOW" alarm will appears you have to shut down all your loads
immediately.
CAUTION
A. Follow the application sofware in use as well as the computer manufacturer's
instructions for saving data and turning off the computer.The remaining of battery
discharge will be enough for you to complete the job.All computer operations
should be terminated as soon as possible.

3.4 Manual Battery Test System
If you push the two buttons together on the front panel for 2 sec. , the UPS will start the battery test
operation and the "BATT.CHK." will appear on the LCD panel . At the end of the test the system
will turn to normal position.
During the battery test operation, the inverter power will be supplied from batteries . At the
end of this test ,if the battery voltage is below a predetermined value, "FAULT..:6" , "BATTERY
LOW " Fault messages appear on the LCD panel and the UPS starts operating in By-Pass
position.
In this case you have to call your service.
If the batteries are in normal conditions the system will start operating in normal mode.
This test protects your operation against unexpected battery failures, and indicates you if there are
any damaged batteries. It also discharges the batteries periodically which is a good thing for
extending battery life.

IV. CUSTOMER SERVICE
WARNING
There are no customer serviceable components inside. DO NOT open the cover or attempt to
service the unit. High voltage may remain when the unit is shut down. Unauthorized service will
void the warranty and could cause serious injury.
4.1 Maintenance
The unit is designed for easy maintenance. Very little customer maintenance is required. The
following will help to ensure trouble -free operation for several years:
1 . Vacuum the dust from the ventilation intake on the front panel.
2 . Wipe the cover with a dump cloth.
3 . Periodically uplug the power cord of the UPS from the wall outlet to test the
batteries condition
CAUTION
It is recommended to test the battery discharging capability only after the software in use has been
saved and all files have been closed.
Due to the unique design, the unit can be serviced only by authorized people. In case of the UPS
fails to operate properly turn off the unit first. Then please call the service.
WARNING
About The Battery:
Only qualified personnel should install or service batteries.
A battery can present a risk of electric shock or burn from high short circuit currents.
The batteries in this UPS are recyclable.
Batteries must be disposed of according to local environmental laws.
Do not dispose of batteries in a fire. The batteries will explode.
The batteries contain lead and pose a hazard to the environment and human health
if not disposed of properly.
Do not open or mutilate the batteries. They contain an electolyte which is toxic and harmful to the
skin and eyes. If electrolyte comes into contact with the skin the affected area should be washed
immediately.
