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.
Do not connect to the equipment like hair dryer or electric heater, to ensure the safety for
UPS
1 SAFETY INSTRUCTIONS
The power output voltage may still have 220V or 120V 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, which will injure due to explosion.
Please do not open the UPS case as you will, there is risk of electric shock

2.1 Unpacking Inspection
Open the UPS package, please check the enclosed accessories including a user manual,
communication cable, support feet, CD-ROM. The long-back model also includes the cable for
connection to battery bank.
Check the UPS if any damage in transport. If find it’s 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.

2.2 Attention Items of Installation
The UPS installation environment 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 will be 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 UPS completely got 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 behind the UPS is off when users connect the load to UPS, and then turn on
the load one by one later.
Please connect the UPS with the socket which is over-current protected. Do not connect the
UPS with the socket which rated current is less than the Maximum input current of the UPS.
All the power socket should be configured with earthling device for safety.
UPS could be electrified or powered no matter the input power cable is tied or not, even when
the UPS is off. The only way to cut off the output is switching off the UPS, disable the EPO and
disconnecting the mains power supply.
For all standard type UPS, it is advised to charge the battery over 8 hours before used. Once the
AC mains power energizes the UPS, it will automatically charge the battery. Without prior
charging, UPS output remains as usual but with shorter back-up time than normal.
When connected to 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.

2.5 External Battery Connection Procedure For Long Back Up Type
For different UPS type, users are instructed to configure different battery voltage as below
sheet. More or less units are forbidden, or else something abnormal or faulty will appear.
2.4 UPS Output Connection
Output connection of 1~10KVA type is configured with sockets or terminal blocks, users can plug
the load cable into the UPS socket to energize the load as below. Make sure the mains wire and
breakers in the building are enough for the rated capacity of UPS to avoid the hazards of electric
shock or fire.
NOTE:
To the type of 6-10KVA, do not use the wall receptacle as the input power source for the UPS,

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 connecting 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 start the charging work automatically.

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 the first use. Once the AC
mains power energizes the UPS, it will charge the battery automatically. Without prior charging,
UPS output remains as usual but with shorter back up time than normal.
Installation steps：
1. Please take out two groups of support feet from package, assemble by embedding them with
each other as shown below.
2. Place the two support feet in parallel on horizontal surface, and then put the machine into
two support feet carefully. Make sure the main power is off when you move it.
