NOTE 2: There are two kinds of outputs: output terminal/outlets and programmable terminal. Please con-
nect non-crical devices to the programmable terminal and crical devices to the output terminal/outlets.
During power failure, you may extend the backup me to crical devices by seng shorter backup me
for non-crical devices.
NOTE 3: Please install the output breaker between the output terminal and the load, and the breaker
should be qualied with leakage current protecve funcon if necessary.
6. Insert the EPO plug into the EPO slot on the rear panel.
7. Put the terminal block cover back to the rear panel of the UPS.
Warning: (Only for standard model)
• Make sure the UPS is not turned on before installaon. The UPS should not be turned on during wiring
connecon.
• Do not try to modify the standard model to the long-run model. Parcularly, do not try to connect the
standard internal baery to the external baery. The baery type and voltage may be dierent. If you con-
nect them together, it maybe causes the hazard of electric shock or re!
Warning: (Only for long-run model)
Make sure a DC breaker or other protecon device between UPS and external baery pack is installed. If not,
please install it carefully. Switch o the baery breaker before installaon.
NOTE: Set the baery pack breaker in “OFF” posion and then install the baery pack.
• Pay highly aenon to the rated baery voltage marked on the rear panel. If you want to change the num-
bers of the baery pack, please make sure you modify the seng simultaneously. The connecon with
wrong baery voltage may cause permanent damage of the UPS. Make sure the voltage of the baery
pack is correct
• Pay highly aenon to the polarity marking on external baery terminal block, and make sure the correct
baery polarity is connected. Wrong connecon may cause permanent damage of the UPS.
• Make sure the protecve earth ground wiring is correct. The wire current spec, color, posion, connecon
and conductance reliability should be checked carefully.
• Make sure the ulity input & output wiring is correct. The wire current spec, color, posion, connecon
and conductance reliability should be checked carefully. Make sure the L/N site is correct, not reverse and
short-circuited.
UPS Installaon for Parallel System
If the UPS is only available for single operaon, you may skip this secon to the next.
1. Install and wires the UPSs according to the Single UPS Installaon secon.
2. Connect the output wires of each UPS to an output breaker.
3. Connect all output breakers to a major output breaker. Then this major output breaker will directly con-
nect to the loads.
4. Each UPS is connected to an independent baery pack.

Single UPS Operaon
Turn on the UPS with ulity power supply (in AC mode)
1. Aer power supply is connected correctly, set the breaker of the baery pack at “ON” posion (the step
only available for long-run model). Then set the line input breaker at “ON” posion(for dual input unit,
also set the bypass input breaker at “ON”). At this me the fan is running and the UPS enter to power on
mode for inializaon, several seconds later, UPS operates in Bypass mode and supplies power to the
loads via the bypass.
NOTE: When UPS is in Bypass mode, the output voltage will directly power from ulity aer you switch on
the input breaker. In Bypass mode, the load is not protected by UPS. To protect your precious devices, you

should turn on the UPS. Refer to next step.
2. Press and hold the “ON” buon for 0.5s to turn on the UPS and the buzzer will beep once.
3. A few seconds later, the UPS will enter to AC mode. If the ulity power is abnormal, the UPS will operate
in Baery mode without interrupon.
NOTE: When the UPS is running out baery, it will shut down automacally at Baery mode. When the
ulity power is restored, the UPS will auto restart in AC mode.
Turn on the UPS without ulity power supply (in Baery mode)
1. Make sure that the breaker of the baery pack is at “ON” posion (only for long-run model).
2. Press the “ON” buon to set up the power supply for the UPS, UPS will enter to power on mode. Aer
inializaon UPS will enter to No Output mode, then Press and hold the “ON” buon for 0.5s to turn on
the UPS, and the buzzer will beep once.
3. A few seconds later, the UPS will be turned on and enter to Baery mode.
Connect devices to UPS
Aer the UPS is turned on, you can connect devices to the UPS.
1. Turn on the UPS rst and then switch on the devices one by one, the LCD panel will display total load level.
2. If it is necessary to connect the inducve loads such as a printer, the in-rush current should be calculated
carefully to see if it meets the capacity of the UPS, because the power consumpon of this kind of loads
is too big.
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 to prevent overload for system
safety.
5. If the overload me is over acceptable me listed in spec at AC mode, the UPS will automacally transfer
to Bypass mode. Aer the overload is removed, it will return to AC mode. If the overload me is over ac-
ceptable me listed in spec at Baery mode, the UPS will become fault status. At this me, if bypass is
enabled, the UPS will power to the load via bypass. If bypass funcon is disabled or the input power is not
within bypass acceptable range, it will cut o output directly.
Charge the baeries
1. Aer the UPS is connected to the ulity power, the charger will charge the baeries automacally except
in Baery mode or during baery self-test.
2. Suggest to charge baeries at least 10 hours before use. Otherwise, the backup me may be shorter than
expected me.
3. Make sure the baery numbers seng on the control board is consistent to real connecon.
Baery mode operaon
1. When the UPS is in Baery mode, the buzzer will beep according to dierent baery capacity. If the bat-
tery capacity is more than 25%, the buzzer will beep once every 4 seconds; If the baery voltage drops to
the alarm level, the buzzer will beep quickly (once every sec) to remind users that the baery is at low level
and the UPS will shut down automacally soon. Users could switch o some non-crical loads to disable
the shutdown alarm and prolong the backup me. If there is no more load to be switched o at that me,
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 Baery mode, if buzzer sound annoys, users can press the Mute buon to disable the buzzer.
3. The backup me of the long-run model depends on the external baery capacity.
4. The backup me may vary from dierent environment temperature and load type.
5. When seng backup me for 16.5 hours (default value from LCD panel), aer discharging 16.5 hours, UPS
will shut down automacally to protect the baery. This baery discharge protecon can be enabled or
disabled through LCD panel control.

01: Output voltage
Interface Seng
Parameter 3: Output voltage
You may choose the following output voltage in parameter 3:
208: Presents output voltage is 208Vac
220: Presents output voltage is 220Vac
230: Presents output voltage is 230Vac
240: Presents output voltage is 240Vac
02: Output frequency
Interface Seng
60 Hz, CVCF mode
50 Hz, Normal mode
ATO
Parameter 2: Output Frequency
Seng the output frequency. You may choose following three op-
ons in parameter 2:
50.0Hz: The output frequency is seng for 50.0Hz.
60.0Hz: The output frequency is seng for 60.0Hz.
ATO: If selected, output frequency will be decided according to the
latest normal ulity frequency. If it is from 46Hz to 54Hz, the out-
put frequency will be 50.0Hz. If it is from 56Hz to 64Hz, the output
frequency will be 60.0Hz. ATO is default seng.
Parameter 3: Frequency mode
Seng output frequency at CVCF mode or not CVCF mode. You may
choose following two opons in parameter 3:
CF: Seng UPS to CVCF mode. If selected, the output frequency will
be xed at 50Hz or 60Hz according to seng in parameter 2.
The input frequency could be from 46Hz to 64Hz.
NCF: Seng UPS to normal mode (not CVCF mode). If selected, the
output frequency will synchronize with the input frequency within
46~54 Hz at 50Hz or within 56~64 Hz at 60Hz according to seng in
parameter 2. If 50 Hz selected in parameter 2, UPS will transfer to
baery mode when input frequency is not within 46~54 Hz. If 60Hz
selected in parameter 2, UPS will transfer to baery mode when
input frequency is not within 56~64 Hz.
*If Parameter 2 is ATO, the Parameter 3 will show the current fre-
quency.
03: Voltage range for bypass
Interface Seng
Parameter 2: Set the acceptable low voltage for bypass. Seng
range is from 110V to 209V and the default value is 110V.
Parameter 3: Set the acceptable high voltage for bypass. Seng
range is from 231V to 276V and the default value is 264V.

value is 46.0Hz/56.0Hz.
Parameter 3: Set the acceptable high frequency for bypass.
50 Hz: Seng range is from 51.0Hz to 54.0 Hz.
60 Hz: Seng range is from 61.0Hz to 64.0Hz.
The default value is 54.0Hz/64.0Hz.
05: ECO mode enable/disable
Interface Seng
Parameter 3: Enable or disable ECO funcon. You may choose fol-
lowing two opons:
DIS: disable ECO funcon
ENA: enable ECO funcon
If ECO funcon is disabled, voltage range and frequency range for
ECO mode sll can be set, but it is meaningless unless the ECO func-
on is enabled.
06: Voltage range for ECO mode
Interface Seng
Parameter 2: Low voltage point in ECO mode. The seng range is
from -5% to -10% of the nominal voltage.
Parameter 3: High voltage point in ECO mode. The seng range is
from +5% to +10% of the nominal voltage.
07: Frequency range for ECO mode
Interface Seng
Parameter 2: Set low voltage point for ECO mode.
50 Hz system: Seng range is from 46.0Hz to 48.0Hz.
60 Hz system: Seng range is from 56.0Hz to 58.0Hz. The default
value is 48.0Hz/58.0Hz.
Parameter 3: Set high voltage point for ECO mode.
50 Hz: Seng range is from 52.0Hz to 54.0 Hz.
60 Hz: Seng range is from 62.0Hz to 64.0Hz.
The default value is 52.0Hz/62.0Hz.
