1 Safety Information

1.1 UPS safety information

 Read all safety information an d operat ing instru ction s caref ully before atte mpting t o

install, service or maintain the UPS. Save this manual properly for reuse.

 This UPS is intended for indoor use only.  Do not operate this UPS in direct sunlight, in contact with fluids, or where there is

excessive dust or humidity.

 Be sure the air vents on the UPS are not blocked. Allow adequate space against

the wall for proper ventilation.

 Do not open the UPS case as you will, there is a high risk of electric shocks inside.

All connection/wiring/s ervicing must be performed by a qualified electrician.

 Do not connect to the equipment like hair dryer or electric heater.  Do not use liquid extinguisher if there is a fire, a dry powder extinguisher is

recommended.

CAUTION

UPS has high voltage inside, do not repair it by yourself. If any questions, please contact local service center or dealer.

1.2 Battery safety information

 Environmental factors impact battery life. Elevated ambient temperatures, poor

quality utility power, and frequent short duration discharges will shorten battery life. Replacing battery periodically can help to keep UPS in normal state and assure backup time required.

 Battery instal ling or replacing should be performed by a qualified electrician. If you

want to replace the battery cable, please purchase it from our local service center or distributors to avoid fever and lighter which can cause fire by inadequate power capacity.

 Batteries may cause electric shocks and have a high short ci rcuit current, follow

below requirements before installing or replacing the batteries. A. Remove wristwatches, rings, jewelry and other conductive materials. B. Only use tools with insulated grips and handles C. Wear insulated shoes and gloves

D. Do not put the metal tools or parts on the batteries

E. Before disconnecting the terminals from the batteries, cut off all the loads to the

battery first.

 Do not dispose of the batteries with fire. The batt er ie s may explode.  Do not open or mutilate batteries. Released electrolyte inside is harmful to the skin

and eyes, and maybe toxic.

 Do not connect the positive pole and negative pole directly, otherwise it will cause

electric shocks or wil l be on fire.

 The battery circuit is not isolated from the input voltage, high voltage may occur

between the battery terminals and ground, check if there is no voltage there before touching.

3 Installation

3.1 Unpacking inspection

 Open the UPS package and inspect the contents upon receipt. The accessories

attached to the UPS contain a power cord, a user manual , communication c able, CD-ROM. The long backup model also includes the cable for connection to battery bank.

 Check if the unit is damaged during transport. Do not power on and notify the

carrier and dealer if find damaged or parts missing.

 Verify this unit is the model you want to buy. Check the model name showed both

on the front panel and rear panel.

Note:

Keep the packaging box and packaging materials for future transport use. The equipment is heavy. Always handle it with care.

3.2 Installation information

 The UPS installation environment must be in good ventilation, away from water,

flammable gases and corrosive entities.

 Do not lie down the UPS agai nst the w all so tha t front an d sid e pane l air int ake h ole,

rear panel air outtake hole will be unobs tructed.

 The ambient temperature around the UPS should be within 0 ℃

（non-condensing）.

 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 shocks.

 Place the UPS near the mains source so that can cut off utility power without any

delay in case of emergency.

 Make sure the load connected to the UPS is off when users connect it to UPS, and

then turn on the load one by one later.

 Connect the UPS with the power outlet which is over-current protected. Do not

connect the UPS with power outlets whose rated current is less than the maximum input current of this UPS.

 All power outlets should be configured with earthing device for safety.  UPS could be electrified or powered no matter the input power co rd is tied 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.

Neutral

 For all standard model UPS, it is advised to charge the batteries over 8 hours

before using. Once the AC mains power energizes the UPS, it will automatically charge the batteries. 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.

 Wiring by a qualified electrician is required. Ensure input cables and output cables

are connected correctly and firmly.

 If install a leakage current protective switch, please install it on output cable.  For 1-3K series long backup model units, you may need to prepare wires for

terminals based on the following table.

3.3 Installation and output connection

Normally, output connection of 1~3kVA series is configured with power outlets or terminal blocks, users can plug the load cable into the UPS power outlets to energize the load. Make sure the mains cable and breakers in the building are enough for the rated capacity of UPS to avoid the hazards of electric shock or fire.

3.4 External batteries connection (long backup model)

 For different UPS model, users are instructed to configure different battery voltage

as below table. More or less units are forbidden, or else something abnormal or faulty will appear.
