The operation of turning on the UPS contains: turning on with utility power
and turning on without utility power.
1) Turning on with utility power:
Connect the mains input to the UPS, press the ON button more than one
second, UPS starts to turn on. At this point, the LCD begins to conduct
self-diagnosis (all the LCD indicators are turn on about 4 seconds). A few
seconds later, the UPS will begin to operate in Normal mode; meanwhile,
the utility power indicator, inverter indicators will turn on. If the utility
power is abnormal, the UPS will work in battery mode.
2) Turning on without utility power:
With no mains input feed to the UPS, press the ON button more than one
second, ups start to turn on, At this point, the LCD begins to conduct
self-diagnosis (all the LCD indicators are turn on about 4 seconds). A few
seconds later, the battery indicator, inverter indicators will be turn on to
indicate that the UPS is working in battery mode.
2. Powering down the UPS
The operation of powering down the UPS contains: turning off ups in normal
mode, turning off ups in battery mode
1) Completely power down the UPS from Normal mode
Hold and press the OFF button persistently for more than 1 second to power

off the UPS. If it bas been set up to work in bypass mode by software, the
bypass indicator will be turned on to indicate that the UPS is working in
bypass mode. In order to cut off the output from the UPS, simply cut off the
utility power supply. LCD begins to conduct self-diagnosis (all the LCD
indicators are turned on about 4 seconds),a few seconds later, not any
display is shown on the front panel and no output is available from the UPS
outlets, system completely power down.
2) Completely power down the UPS from Battery mode
Press the “OFF” button persistently for more than 1 second to power off the
UPS. When being powered off, the LCD will start self-diagnosis (all the
LCD indicators are turn on about 4 seconds), a few seconds later, not any
display is shown on the front panel and no voltage output is available from
the UPS outlets, system completely power down.
5.3.2 Conducting Battery self-diagnosis
In UPS operation, users can manually initiate battery self-diagnosis to check
the battery conditions. There are two methods to initiate the battery
self-diagnosis:
1. Through the function button
In normal mode, press and hold the function for more than 2 seconds until
the buzzer beeps twice. At this point the indicators (LED7~10) will blink
cyclically, indicating the UPS has worked in battery mode and the battery
self-diagnosis has started. The battery self-diagnosis will last for 10 seconds
default. In the event of a battery fault during battery self-diagnosis, the UPS
will transfer to normal mode automatically.
2. Through the monitor software
Users can also initiate battery self-diagnosis through the background
monitoring software.

1) Connect the mains input to the UPS, and make the UPS works in standby
mode or bypass mode.
2) Press the 'F' and 'OFF' button more than one second, then release, the buzzer
will beep once, the "OUTPUT" is flashing, which means all of bottom are
used for UPS setting, at this point, if the "VAC" is flashing, which means the
output voltage is set to enable; if the "Hz" is flashing, which means the
frequency is set to enable, the LCD screen indicator represents current
output voltage and frequency setting value.
3) If you need to set the voltage, check the voltage setting is enabled ("VAC" is
flashing), If not, press the 'F' more than one second, then release,the output
setting is enabled, at this point you can start to set output voltage.
4) Release the 'OFF' key after you press it more than one second, LCD display
the selected output voltage in turn.
5) Repeat the fourth step until the LCD indicator meets the required voltage
6) Press 'ON' key about one second, the output voltage setting completed.
7) The frequency setting is the same as the voltage setting, but before the
setting, please confirm the frequency setting is enabled ,if not, press 'F' key
about one second in order to switch to the frequency setting screen ("Hz" is
flashing).
8) When done, Press the 'F' and 'OFF' button more than one second, then
release, the buzzer will beep once, exit the setting mode.

6 Maintenance
6.1 Battery Maintenance
The battery is key component of the UPS. The battery life depends on the
ambient temperature, charging and discharging times. High ambient
temperature and deep discharging will shorten the battery life.
1. Sealed maintenance-free lead –acid battery be used in the standard. When
being connected to the utility power whether the UPS has been turned on or
not, the UPS keeps charging the battery and also offers the protective
function of charging and discharging.
2. Keep the ambient temperature between 15℃ and 25℃
3. If the UPS has not been used for a long period, charging is recommended at
the intervals 3 months.
4. Batteries should not be replaced individually.
5. Under normal conditions, the battery life lasts 3 to 5 years. In case if the
battery is found not in good condition, earlier replacement should be made.
The battery should only be replaced by qualified service personnel.
Note: 1.Prior to battery replacement, the UPS must be turned off and disconnected
from utility power.
2. Metal objects such as rings and watches should be removed.
3. Use the screwdriver with insulated handle. Tools and other metal objects
should not be placed on the battery.
4. Short circuit or reverse connection between the positive and negative
terminal of the battery is strictly forbidden.

6 Maintenance
6. 2 Checking UPS function
Every time when conducting field maintenance, please check the regular
function of the UPS, including:
1. Check the operation status of the UPS
If the main voltage is within the specifications, the UPS should operate in
normal mode; if the main voltage is abnormal, the UPS should operate in
battery mode. In both cases, there should be no fault indication.
2. Check the transfer between the UPS operation modes
Disconnect the main input to simulate a mains failure, the UPS should
transfer to battery mode and operate normally; then recover the mains input,
the UPS should transfer to normal mode and operate normally
3. Check the LED indicators of the UPS
During the check processes stated above, check that the LED indication of
the UPS agrees with the UPS operation mode.
