Please observe the warnings on the machine and manual strictly
and properly keep the manual. Do not operate the UPS
before reading through all safety notes and operating instructions.

Safety notes
Operating safety
1. Read safety notes carefully and thoroughly before operation, ensure the
proper usage and save this manual properly.
2. Pay attention to alarm table on the UPS and operate following it.
3. Avoid installing the UPS near water or in excessive humidity.
4. Avoid installing the UPS where it would be exposed to direct sunlight or
nearby heater.
5. The UPS must be stored in a location with good ventilation and ensure
enough space on each side for ventilation.
6. No liquid or spray detergent to clean the UPS.
7. Use powder fire extinguisher in the event of fire occurring in the vicinity.
Liquid fire extinguishing agents may causes electric shock.
Electric safety
1. UPS has provided earthed terminal, in the final installed system
configuration, equipotential earth bonding to the external UPS battery
cabinets, connect the earth before connecting to the building wiring terminal.
2. Before moving or re-wiring the UPS, please disc onnect the ma ins source and
make sure the UPS is completely shut down. If not, the o utput terminal may
be electrically live that may causes electric shock.
3. Please use fitting and accessories appointed by JFY.
4. To meet the requirement of EMC, the length of output line should be less
than 40m distance.
Battery safety
1. B attery should be replaced periodically to ensure normal UPS operation and
adequate autonomy time because of high ambient temperature shortening the
battery lifetimes.
2. Battery should be managed by professional personnel.
3. Do use the same type and same number of batteries in replacement.
4. In ca se of electrical shock and high short circuit current, please observe the
precaution as follows:
A. Remove watches, rings, or other metal object from the hands;
B. Use tools with insulated handles;
C. Wear rubber gloves and boots;
D. Do not lay tools or metal parts on top of batteries;
E. Disconnect the load before operate the terminal of battery.
5. Do not attempt to dispose of batteries by burning them. This could cause
battery explosion. The batteries must be rightly deposed according to local
Page 5
regulation.
6. Do not open or destroy batteries. Escaping electrolyte can cause injury to the
skin and eyes. It may be toxic. If electrolyte comes into contacting with the
skin, wash the affected area with plenty of clean water immediately and go
to the hospital for a check.
7. Do not make the positive and negative terminals of the battery short circuit;
otherwise it may cause electric shock or fire.
Maintenance
The operating environment and storage method are two key factors affecting
the lifetime and reliability of the UPS. Hence, it is advisable not using the
device in the following environments:
1 Where the temperature and relative humidity are outside the
specifications (temperature: 0-40℃, relative humidity: 20-90%).
2 Where vibrations or shocks are existing.
3 Dust, corrosive agents or salts or inflammable gas are present.
If the UPS will remain idle for a long period, it must be stored in a dry
environment. The storage temperature should range from -25-55 (without ℃
battery). Before power on the UPS, set the ambient temperature over 0 and ℃
keep more than 2 hours.

1 Introduction
This series UPS is a advanced on-line sine wave uninterruptible power system
with parallel redunda ncy function and t he maintenance swi tch is optional. Pr ovide
a high quality AC power for your precision equipment with a wide range of
application. It’s ideally suited for computer equipment, communication system,
industry automatic control equipment. Because of the on-line design, the input
voltage always would be adjusted and filtered differing from backup UPS. When
power outage, battery will supply the load without transfer time. When over load or
fault of inverter，UPS will turn t o bypass mode and supplied by the utility power.
At the time of eliminating over load，UPS will automatically turn to supplied by
the inverter.
This manual is suitable for XPC series produces as follows:
1106：inner battery normal model
1106L：external battery long backup model
1110：inner battery normal model
1110L：external battery long backup model
3110L：3 phase in, 1phase out, external battery long backup model
3115L：3 phase in, 1phase out, external battery long backup model
3120L：3 phase in, 1phase out, external battery long backup model。
Meanwhile each model can be divided into normal and professional version for
user choice. Professional version is added with EPO switch and manual

RS232 communication port: connect the UPS and the monitor
The RS232 communication cable conncet to the serial port of the computer
The RS232 communication cable conncet to the RS232 communication port of
UPS.
The DIN configuration of the RS232 interface port on UPS is as following：
2.6 Parallel card（Optional）
Redundancy ntroduce
N+X is the now dependable power supply structure. N is indicate the least number
of UPS all the load need; X is indicate the redundancy number of UPS that can be
suppoted by the system. More bigger of X, more dependable of the system. N+X is
the best solution for the high dependable situation. Just with parallel card and data
line, it can be paralleled with maximum 3 UPS.
Parallel installation
Parallel function is optional. You can buy parallel fittings by yourself (including
parallel card and data line) . customer service staff will install to ups, The max
number of parallel is 3, Parallel UPS must have independent batt ery.

the data Line successively connection
2) All of UPS output cable connect to a connection tray, Then use the connection
tray to load
Attention: Output cable require:
If the distance between ups to load less then 20m, require every UPS output cable
length disparity under 20%; If the distance between ups to load over then 20m, require
every UPS output cable length disparity under 10%.

4.1 Start up
Attention: The battery is fully charged before delivery. However storage and
transportation will inevitably cause some charge loss. Therefore, it's advisable to
charge the battery for 10 hours before using it, to ensure adequate battery autonomy.
Note: means LED lighting, and means LED is faded.
Turn on the UPS with utility power supply (in AC mode)
After power supply is connected correctly, set the input breaker at "ON" position.
Then press and hold the "ON" button more than 2s to turn on the UPS, at this time
self-test is running (If the UPS is in normal operation, it will show full screens one
by one). The basic information of UPS can be showed on LCD panel.

3) Press and hold on/off button more than 2s, the UPS shut down and save the
settings. When power on UPS next time, UPS will charge the battery according
to the last time saved settings.
4) The setting interface is available in AC mode, battery mode, bypass mode.
5 Battery Maintenance
The UPS requires very little maintenance. Built-in batteries are sealed,
maintenance-free and just always be charging for the expected life. When
connecting to the utility powe r, regardless of whether the UPS is on, the
batteries are charged all the time with protection for overcharge and over
discharge by the UPS.
If the UPS will remain idle for a long period, it should be charged every 4-6
months; When in high temperature, the batteries should be charged and
discharged every 2 months, and the charging time should be more than 12
hours.
Normally, the serve time of batteries is 3-5 years. Should you detect a
problem, it’s demand for an early replacement and the replacement may be
carried out only by professional personnel.
When replace the batteries, install the same number and same type of batteries.
The replacement of single battery is deprecated. The whole replacement
should be observed the supplier’s instruction.
Normally (supplied by t h e batteries rarely), the batteries should be charged
and discharged every 4-6 months. Keep to be charge d when discharged to
shout down of UPS and the standard charging time should be mor e than 12
hours.
