3. Operations

Mode/Status

Description

UPS Power On

When UPS is powered on, it will enter into this mode for a few seconds for
initializing the CPU and system.

AC Mode

When the input voltage is within acceptable range, and the UPS is turned on (the
inverter is running), the UPS will provide pure and stable sine wave AC voltage. The
UPS will also charge the battery in AC mode.

ECO Mode

When the input voltage is within voltage regulation range and ECO mode is
enabled, the UPS will bypass voltage to output for energy saving. If the input
voltage is out of the regulation range but it is still within acceptable range of AC
mode, the UPS will transfer to inverter supplying the power to load (similar as AC
mode).

Converter Mode

When input frequency is within 46 to 64Hz, the UPS can be set with a constant
output frequency (50 Hz or 60 Hz) through the inverter. The UPS will still charge
battery at this mode. There is no bypass at this mode.

Battery Mode

When the input voltage is out of the acceptable range or power failure, and the UPS
is turned on (the inverter is running), the UPS will backup power from battery.

Bypass Mode

When input voltage is within acceptable range and bypass is enabled, and the UPS
(inverter) is not turned on or the inverter can’t support the load, the UPS will supply
power to the load through bypass.

Battery Test Mode

When the UPS is in AC mode or Converter mode, and the battery test command is
enabled through LCD or monitoring software, the UPS will start Battery Test. This
operation is used to check the battery status.

Warning Status

If some errors occur in the UPS (but it is still running normally), buzzer will alarm
and warning code will appear in the LCD for trouble shooting.

Fault Mode

When fatal error occurs in the UPS, it will beep continuously and go to fault mode.
It will display fault codes in LCD.

3-5. Single UPS Operation

3-5-1. Turn on the UPS with utility power supply (to Line mode)

1) Make sure mains input and battery are connected well, and the battery pack breaker is at “ON”

position; Set the external mains input breaker to “ON” position, then the fan will be running and the
UPS supplies power to the loads via bypass; (The UPS is operating in Bypass mode.)

NOTE: When UPS is in Bypass mode, the output voltage comes directly from utility, so the load is not
protected by UPS. To protect the precious load, the UPS should be turned on to Line mode.

2) When LCD is on home page, press the “ON/ENTER” button, LCD will show a prompt page of “Turn On”;

Move the arrow to “Yes” by up or down button, then press “ON/ENTER”, the UPS will be starting up
with beeping once. You could also enter the “control menu” to select the instruction “Turn On” to
startup the UPS. Please refer to the section of “LCD operation”.

3) A few seconds later, the UPS will enter into Line mode; “Line mode” will be displayed on LCD. (In line

mode, if the utility power is abnormal, the UPS will transfer to Battery mode without interruption.)

3-5-2. Turn on the UPS without utility power supply (to Battery mode)

1) Make sure the battery is connected well and the battery pack breaker is at “ON” position;

2) Press the “ON/ENTER” button to start up the internal power, the UPS will enter into bypass mode
without output;

3) When LCD is on home page, press the “ON/ENTER” button, LCD will show a prompt page of “Turn

On”; Move the arrow to “Yes” by up or down button, then press “ON/ENTER”, the UPS will be starting
up with beeping once. You could also enter the “control menu” to select the instruction “Turn On” to

startup the UPS. Please refer to the section of “LCD operation”.

4) A few seconds later, the UPS will enter into Battery mode; “Battery mode” will be displayed on LCD
(In Battery mode, it will shutdown automatically when battery is depleted. If the utility power is restored,
it will auto restart to Line mode.)

3-5-3. Connect devices to UPS

After the UPS is turned on, you can connect devices (load) to the UPS.

1) Turn on the UPS first and then switch on the devices one by one, the LCD panel will display total load
level;

2) If inductive loads needed to be connected, such as a printer, the in-rush current should be calculated
carefully to see if capacity of the UPS can cover due to the huge starting power consumption of this
kind of load;

3) If the UPS is overload, the buzzer will beep twice every second;

4) When the UPS is overload, please remove some loads immediately. It is recommended to have the
total loads connected to the UPS less than 80% of its nominal power capacity for system safety;

5) If the overload time is over duration listed in spec at Line mode, the UPS will automatically transfer to
Bypass mode. After the overload is removed, it will return to Line mode. If the overload time is over
duration listed in spec at Battery mode, the UPS will become fault status. At this time, if bypass is
enabled, the UPS will power to the load via bypass. If bypass function is disabled or the input power
is not within bypass acceptable range, it will cut off output directly.

3-5-4. Charge the batteries

1) After the UPS is connected to the utility power, the charger will charge the batteries automatically
except in Battery mode or during battery test;

2) Suggest to charge batteries at least 10 hours before use. Otherwise, the backup time may be shorter
than expected;

3) Make sure the battery numbers setting on the control board (Please refer to the section of changing
battery quantity) is consistent with actual connection.

3-5-5. Battery mode operation

1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity.
Normally, the buzzer will beep once every 4 seconds in battery mode, but when the battery voltage
drops to the alarm level, the buzzer will beep once per second and the UPS will shut down
automatically soon. Users could switch off some non-critical loads to disable the shutdown alarm and

prolong the backup time. If there is no more load to be taken off at that time, you have to shut down
all loads as soon as possible to protect the devices or save data. Otherwise, there is a risk of data loss
or load failure;

2) In Battery mode, if buzzer sounds annoying, you could enter ”Control->Mute” on LCD to silence it.
Please refer to the section of “LCD operation”;

3) The backup time of the long-run model depends on the external battery capacity;

4) The backup time may change under different environment temperature and load type;

5) The maximum backup time is limited by default 16.5 hours (After discharging 16.5 hours, UPS will
shut down automatically to protect the battery). The time could be modified through LCD panel or
communication port.

3-5-6. Test the batteries

1) If you need to check the battery status or performance when the UPS is running in Line / Converter /

ECO mode, you could enter ”Control->Batt Test” to instruct the UPS to do battery test. Please refer to
the section of “LCD operation”;

2) Users also can set battery test through monitoring software;

3) If the UPS is in battery testing, “Battery test mode” will be displayed on LCD, the buzzer indication
will be the same as Battery mode, but both line LED and battery LED will be lit.

3-5-7. Turn off the UPS with utility power supply in Line mode

1) When LCD is on home page, press the “OFF/ESC” button, LCD will show a prompt page of “Turn Off”;
Move the arrow to “Yes” by up or down button, then press “ON/ENTER”, the UPS will be turning off to
bypass mode with beeping once. You could also enter the “control menu” to select the instruction
“Turn Off” to turn off the UPS. Please refer to the section of “LCD operation”;

NOTE: Here, “Turn Off” means that UPS is not working on line / converter / ECO / battery / battery

test mode. So even though the UPS is turned off, if input or bypass voltage is normal, the internal
power supply will be still working; and if bypass status has been set to “enable”, the output voltage of
the UPS will be still exist;

2) If you need to fully cut off the output, please switch off the external input breaker. A few seconds later,

there is no display shown on the panel and UPS is completely off.

3-5-8. Turn off the UPS without utility power supply in Battery mode

1) When LCD is on home page, press the “OFF/ESC” button, LCD will show a prompt page of “Turn Off”;

Before storing, charge the UPS at least 7 hours. Store the UPS covered and upright in a cool, dry location.

During storage, recharge the battery in accordance with the following table:

5-2. Maintenance

The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified

maintenance personnel.

Even after the unit is disconnected from the mains, components inside the UPS system are still

connected to the battery packs which are potentially dangerous.

Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that
no current is present and no hazardous voltage exists in the terminals of high capability capacitor such as
BUS-capacitors.

Only persons are adequately familiar with batteries and with the required precautionary measures
may replace batteries and supervise operations. Unauthorized persons must be kept well away from the
batteries.

Verify that no voltage between the battery terminals and the ground is present before maintenance
or repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may
occur between the battery terminals and the ground.

Batteries may cause electric shock and have a high short-circuit current. Please remove all
wristwatches, rings and other metal personal objects before maintenance or repair, and only use tools with
insulated grips and handles for maintaining or repairing.

When replace the batteries, install the same number and same type of batteries.

Do not attempt to dispose of batteries by burning them. This could cause battery explosion. The
batteries must be rightly deposed according to local regulation.

Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may
be toxic.

Please replace the fuse only with the same type and amperage in order to avoid fire hazards.

Do not disassemble the UPS system.
