Please strictly obey all the instructions in this manual and pay attention to all the warning and operation
information. It is not advisable to install or operate the machine before read this manual.
1. Safety Instructions
●The power outlet voltage may still have 220V even not connect to the mains power.
●For the battery cable or power cord replacement, please contact our service station or dealer to
purchase, in order to avoid fire caused by inadequate capacity or heat ignition.
●Do not place the battery or battery pack in the fire, that will injure due to explosion.
●Please do not open the UPS case as you will, there is risk of electric shock.
●Do not touch the battery connection terminals. Battery loop and input voltage loop is without
isolation, which may cause high voltage risk between the battery terminal and ground.
●Should not connect the equipment like hair dryer or electric heater, to ensure the safety for the UPS.
Attention：
UPS has high voltage inside, for thepersonal safety, please do not repair by yourself. If any questions,
please contact local service center or dealer.
2. Installation Instructions
2.1. Unpacking Inspection
●Open the UPS package, please check the enclosed accessories including a user manual,
communication cable, support feet, CD-ROM, the cable for connection to battery bank.
●Check the UPS if any damage in transport. If found damaged or parts missing, do not power on,
please turn to the carrier and dealer.
●To determine whether this UPS is the model you want to buy. Check the model name showed both
on the front panel and rear panel of UPS to confirm.

Note：
Please save the packaging box and packaging materials for future transport use. As heavy product,
please transit the UPS with care.
2.2. Attention items of installation
●The UPS location circumstance must be with good ventilation, away from water, flammable gases
and corrosive entities.
●Do not lie down the UPS against the wall so that front and side panel air intake hole, rear panel air
outtake hole unobstructed.
●The peripheral environment temperature around the UPS should be within 0 ℃~ 40 ℃.
●If dismantling the machine at low temperatures, there may be condensation droplets, users can not
install or operate it before completely getting dry both inside and outside, otherwise there will be
danger of electric shock.
●Place the UPS near the mains socket to cut off AC mains without any delay at any emergent case.
Attention：
●Make sure the load after the UPS is off when user start wiring the load to UPS, then turn on them
one by one later.
●Please connect the UPS with the socket which is over-current protected.
●All the power socket should be configured with earthling devise for safety.
●UPS could be electrified or powered whether the input power cable is tied on or not, even when the
UPS is off. The only way to cut off the output is switching off the ups and disconnecting the
mains power supply first and second.
●For all standard type UPS, it is advised to charge the battery over 8 hours before virginally used.
Once the AC mains power energizes the UPS, it will auto-start the charging work. If without prior
charging, UPS output remains as usual but with shorter back up time than normal.
●When connect motor, display equipment, laser printer etc, UPS power selection should be based on
the startup power of the load which is usually twice as rated power.

●One end of battery cable is for UPS terminals while the other end with triple cables is for battery
terminals. Correct installation procedure is highly vital or else probable electric shock will arise.
Users are strictly required to follow the below procedure.
●Connect battery in correct way and make sure the total battery voltage is available for UPS.
●Correctly connect the long battery cable to battery terminals first, red wire is to positive plate while
black is to negative. If users connect the UPS first, electric shock or other danger could not be
avoided.
●Before connect load after UPS, users should supply main power to UPS and energize it.
●Connect long battery cable to UPS terminals with correct poles link (red is for “+”,black is
for“－”), UPS will auto start the charging work.

2.6 Installation
●UPS installation work should comply with local electrical standard and only can be done by
professional technician. 1KVA~3KVA units could use wall socket as input power connection.
●For all type UPS, it is advised to charge the battery over 8 hours before virginally used. Once the AC
mains power energizes the UPS, it will auto-start the charging work. If without prior charging, UPS
output remains as usual but with shorter back up time than normal.

4. Working mode introduction
4.1 Bypass mode
LED indications on front panel on bypass mode are as following:
Bypass yellow LED is on, the buzzer beeps once every 2 minutes . The warning red LED is on when
beeping, LCD displays are according to the exact load and battery capacity.
Turn to bypass mode under the following two conditions:
①Turn off the UPS on line mode while start the bypass output.
②Overload on line mode.
NOTE: When UPS is working on bypass mode, it has no back up function.
4.2 Line mode
LED indications on front panel on line mode are as following: The inverter green LED is on.
When input AC mains is in line with the working conditions, UPS will work on line mode.

- 17 -
4.3 Battery mode
LED indications on front panel on battery mode are as following: both the inverter green LED and
battery yellow LED are on, the buzzer beeps once every 4 seconds. The warning red LED is on when
beeping.
When the mains power down or instable, UPS will turn to battery mode at once.
4.4 ECO mode
LED indications on front panel on ECO mode are as following: both the inverter green LED and
bypass yellow LED are on.
When the input mains meets the input range of the ECO mode and start the ECO function, the UPS
will works on ECO mode. If inputAC mains exceeds the range of ECO several times in a row in a
minute but stays in inverter input range, UPS will work on AC inverting mode automatically.
4.5 Fault mode
LED indications on front panel on Fault mode are as following: warning red LED is on and LCD
display fault code and related icon.
FAULT
Fault mode (LCD interface on which the fault code display)
When UPS has fault. The warning LED is on and the buzzer beeps. UPS will turn to fault mode. UPS
cuts off the output and LCD display fault codes. At the moment, you can press the mute key to make
the buzzer stop beeping temporarily to wait for maintenance. You can also press the OFF key to shut
down the UPS when confirm that there is no serious fault.
