3. INSTALLATION
3.1 Inspecting the packing carton for damage that may have occurred while in transit. Immediately
notify the carrier and place of purchase if any damage is found. Retain the package for future use.
3.2 Plugging the power cord to a 3-wire grounding receptacle. If an extension cord must be used
between the INVERTER AND UPS and the nearest wall outlet, use a 3-wire grounding type with
rating, at least, for full load of input current as stated in item 8, Specifications.
3.3 Connecting your equipment to the UPS. To ensure that your computer equipment will be
protected during a utility failure, it is important to make sure that the maximum power needed by the
equipment is not over the rated capacity of the UPS. Red LED will light up (LED version), or the
“Over load” symbol will show up (LCD version), and alarm will beep if the load is over the rated value.
Meantime, if the overload is severe, the UPS will shut down immediately for protecting UPS itself.
3.4 If you are going to use the setting software (i.e. UPS Wizard), connect your computer to the
communication port of UPS (RS-232) with the supplied communication cable.
3.5 After installation with normal city power, the UPS will charge the battery automatically; please
keep the UPS in charging for 5 hours, at least.
3.6 Important Safety Instruction
SAVE THESE INSTRUCTIONS. This manual is important instructions that you should follow
during installation and maintenance of the UPS and batteries. Please read all instructions before
operating the equipment and save this manual for future reference.

4. OPERATION
4.1 Once it’s connected with normal city power, the UPS will charge the battery automatically,
when UPS is off, the status LED (in LED version) blinks green every 2 seconds; or in LCD version,
the battery symbol and battery level will blink every second during charging. If AC auto turn-on
function is enabled, the UPS will turn on automatically when city power is normal. If auto turn-on
is disabled, please push the button for about one second on the front panel; then the UPS will give
power to the outlets after a short-time of beeping.
4.2 Pushing the button for 4 seconds, the UPS will turn off the power on the outlets. But, the
UPS will keep charging if city power is normal. To stop the charging, please pull out the power
cord to shut down the UPS completely.
4.3 DC start: During a blackout, push the button one second for entering “OFF” mode (LCD
showing “OFF” or LED blinking orange); then push again for one second, and the UPS will be
turned on and enter into backup mode. To turn off the power from UPS; please push the button
for 4 seconds; then the status LED (in LED version) will blink orange every 2 seconds; or LCD
display will show “OFF” (in LCD version); then, wait for 10 seconds, and UPS will turn off the power
automatically.
4.4 In “OFF” mode, UPS will turn off power completely in 10 seconds during a utility failure; while
UPS will keep charging the batteries if the utility power is normal. When utility power is normal,
please pull out the power cord if you want to turn off the UPS completely.
4.5 To test the battery and inverter of UPS, you can unplug the I/P cord, but it is more convenient to
push the main control button for one second, the UPS will simulate a 10 seconds blackout and
transfer to battery mode for discharging test. To cancel self-test, please push the control button
for 2 seconds.
4.6 Under battery mode, when battery voltage is too low or too high, the UPS will emit alarm, if the
under voltage or over voltage is too much, the UPS will turn off the UPS automatically.
4.7 When a blackout happens, the buzzer will emit two beeps every 8 seconds for alarm. You can
disable the alarm by setting silence mode; to push the main control button will disable the alarm, and
to push it again will enable the alarm, the setting can be shown on LCD display.
Note: The main control button will provide test function at normal mode, but will become with
alarm-reset function at battery mode.

14
4.8 Battery charging mode: The UPS provides two charging modes for the battery, quick charging
and trickle charging. The quick charging provides higher charging current when battery is empty
and reduces the charging current when battery voltage increases. Trickle charging will begin
automatically after battery is 90% fully charged.
4.9 Green mode setting (by UPS wizard software or through LCD display)
When “Green Power” function is enabled, the UPS will turn off the power within 60 seconds after
blackout occurs with the power consumption lower than the pre-set level (adjustable from 1% to
14% of full load). The default value of green mode setting is zero (disabled). Please use the
UPS wizard software to adjust this level.
4.10 Battery capacity balance discharging
In the structure, the battery is composed with many 2VDC cells in series connection. When
UPS is installed, the batteries are charged and discharged by the same current. In theory, all
battery cells have the same charging capacity; but in fact, each cell has a small difference of
self-discharge rate in a long term, in which, the small difference of self-discharge rate will cause
big difference among all the charged batteries. This phenomenon may not only shorten the
battery life, but also cause wrong detection of "Replace battery". To prevent the wrong detection
and to keep UPS batteries in the best condition, the battery needs capacity-balance discharge
every 12 months; which is to discharge the UPS batteries to low battery alarm by disconnecting
the AC input with the UPS and use a table lamp as the load. Do not use PC as the load when
doing capacity-balance discharge to prevent from data loss at low battery shut-down. The lower
the load, the better the balancing effect.
Note: If an UPS is stored in stock, please recharge the battery set every 6 months, at least; or the
battery life will be shortened.
4.11 There are two ways to change the setting of UPS. The 1st way is to use the UPS Wizard
software, please contact your service people for detailed information. The 2nd way is to make it
through the LCD display, by the following procedures:
4.11.1 To push the two selection buttons, △and ▽, at the same time for 3 seconds until the LCD
display begins to blink.

15
4.11.2 To change the UPS O/P frequency at DC start
When the frequency value is blinking, push any selection button, △or ▽, for 1 second to change
the frequency setting! The setting will keep changing every 2 seconds if you keep pushing the
button. Push two selection buttons at the same time for next setting, or leave the LCD blinking
without pushing any button for 30 seconds to end the setting.
4.11.3 To change the UPS rated voltage
When the voltage value is blinking, push any selection button for 1 second to change the rated
voltage. Keep pushing the button until the required voltage blinking. Then, push two selection
buttons at the same time for next setting, or leave the LCD blinking for 30 seconds to end the
setting.
4.11.4 To change the Auto-turn-on setting at the recovery of utility power
The method of changing the setting is similar to that of voltage setting. If you don’t need
Auto-turn-on function, please select “oFF”. To select “On” is for immediate auto turning on at the
recovery of utility power. While the “On.S” means auto turning on with safety mode. Sometimes,
when battery is empty after blackout, the auto turn-on function will have very short backup time if
blackout happened again following with a short time recovery. To select “On.S” will provide
Auto-turn-on only when the battery is charged for, at least, 30% of its capacity.

16
4.11.5 To change the green mode level at battery mode
When the “Gn.0” is blinking, it means the green mode level if off. The UPS will not turn off the
power automatically if there’s no any load connected to UPS. When the “Gn.1” is blinking, it
means the green mode level is 1%of full load level. The UPS will turn off the power automatically
if blackout happened when load level is less than 1% of full load.
Push the selection button “△“ for 2 seconds at least, to increase the green mode level or push
“▽“ to decrease the level. Push two selection buttons at the same time to end the setting.
