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 the personal safet y, please do not repair by yourself. If any quest ions,
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 lo cation circumstance must be with good ventilation, awa y from water, flammable gases
and corrosive entities.

● Do not li e down the UPS against the wall so that front and side panel air intake hole, rear p anel 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 t o 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 t ype 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 b attery 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.
