1 Precautions

1.1 Transportation

Before transporting the UPS, pack it with original packing materials to protect it from

collision.

1.2 Preparation

 The UPS may have condensation inside after it is moved from a cold environment to a

warm environment, such as an indoor environment. In this case, install the UPS after it is

completely dry. Therefore, install the UPS at least 2 hours after it is placed in the target

place.

 Never install the UPS in a damp environment or a place with water nearby.

 Never install the UPS in a place exposed to sunlight or with a heater nearby.

 Never block or shield the air vents on the UPS shell.

1.3 Operating Environment

The UPS is used for commercial and industrial purposes only. It cannot be used as a power

supply for life support devices.

The TIER4 or TIER3 power supply architecture specified in TIA942, that is, dual power

supply routes, must be used in the power supply systems that are crucial to major economic

interests or order of public places, such as the national computing center, military command

system, emergency command center, railway signal system and control center, civil aviation

air traffic control center, airport command center, financial clearing center, and transaction

center.

Ensure that the product is used in an environment that meets the product design specifications

(including power grid, temperature, and humidity) to avoid causing malfunctions, damaging

components, or voiding the warranty.

The UPS operating environment must meet the requirements for the climate indicator,

mechanically active substance indicator, and chemically active substance indicator in ETSI

EN 300 019-1 class 3.6.

UPS2000-G-(1 kVA-3 kVA)

User Manual

 After unpacking the UPS, you are advised to power on the UPS as soon as possible. If you

temporarily do not use the UPS, take appropriate measures to prevent moisture, dust, and

foreign matter from entering the UPS.

 After unpacking batteries, you are advised to connect the battery supply as soon as

possible. If you temporarily do not use the batteries, store them in dry and clean

environments. If batteries are stored for more than 90 days, charge them in time.

Otherwise, the battery lifespan may be affected.

Do not place the device in an environment that has inflammable and explosive air or gas. Do

not perform any operation in this kind of environment.

If the valid mains voltage exceeds 320 V AC, the UPS may be damaged.

Any operation on any electrical device in an environment that has inflammable air can cause

extreme danger. Strictly obey the operating environmental requirements specified in related

use manuals when using or storing the device.

Do not place the UPS in the following environments:

 The environment that is close to flammable or explosive materials, dust, corrosive gases

or dust, conductive or magnetic dust, abnormal vibration, or collision.

 Rooms or outdoor environments where temperature and humidity are not controlled

(with high temperature, low temperature, moisture, direct sunlight, or heat sources).

 Non-confined environment near the ocean (0–3.7 km) and indoor or semi-indoor

environment where the temperature and humidity are not controllable, such as a simple

equipment room near the ocean, citizen house, garage, corridor, direct ventilation cabinet,

house with only the roof, railway station platform, gymnasium, aquarium, and so on.

 The environment that is conducive for the growth of microorganisms such as fungus or

mildew.

 The environment where rodents (such as mice) and insects exist.

1.4 Installation

 Never connect a device that will overload the UPS, such as a laser printer, to the output

socket of the UPS.

 When routing cables, keep them away from the place where they are easily to be stepped

on or make someone stumble.

 Never connect household appliances, such as a hair drier, to the output socket of the

UPS.

 The power to the UPS must come from a near grounded cushion socket.

 Use only power cables that comply with Verband Deutscher Electrotechniker (VDE) test

standards and Conformité Européenne (CE) certification to connect the UPS to the

indoor cushion socket. The power cable can be the main power cable for your PC.

UPS2000-G-(1 kVA-3 kVA)

User Manual

 Use only power cables that comply with VDE test standards and CE certification to

connect a load to the UPS.

 When installing the UPS, ensure that the total leakage current of the UPS and connected

loads does not exceed 3.5 mA. The recommended upstream earth leakage circuit breaker

(ELCB) is more than 30 mA.

1.5 Operation

 Never disconnect the main power cable for the UPS or use the indoor cushion socket

when the UPS is running. Otherwise, the grounding for the UPS and connected loads

will become invalid.

 Since the UPS contains embedded batteries, its output sockets and output terminals are

energized even if the UPS is not connected to a socket.

 To completely disconnect the UPS, shut down the UPS and then unplug the power cable.

 Prevent liquid or any other foreign objects entering the UPS.

1.6 Servicing, Maintenance, and Troubleshooting

 Since the UPS uses dangerous voltages, only qualified personnel are allowed to maintain

the UPS.

 Before any maintenance or servicing, remove embedded batteries and ensure that no

current exists, especially that no voltage exists between bus capacitors.

 Batteries are allowed to be replaced only by or under the instructions of the personnel

that are familiar with batteries under safe conditions. Unauthorized personnel are not

allowed to get close to batteries.

 Batteries may generate an extremely high short-circuit current due to short circuits.

Therefore, take the following preventive measures before maintaining batteries:

− Remove any metal objects from yourself, such as watches and rings.

− Use only insulated tools.

 When replacing batteries, install the batteries of the same quantity and model as the old

ones.

 Do not throw batteries into fire, which may cause explosion.

 Do not break down or damage batteries. The electrolyte will damage your skin and eyes

once it leaks.

 When replacing fuses, use the fuses with the same model and specifications as the old

ones to avoid fire disaster.

 Do not disassemble the UPS.

UPS2000-G-(1 kVA-3 kVA)

User Manual

 Electric shock risk. The UPS is still energized even if it is disconnected from the socket,

because its internal components are still connected to embedded batteries.

 Electric shock risk. The battery circuit is not disconnected from the input voltage. It is

possible to have a dangerous voltage between the battery terminal and the ground cable.

Therefore, ensure that no voltage exists before touching the UPS interior.

5 Operations

5.1 Checking Before Powering On the UPS

 AC power cable colors comply with local electrical regulations.

 No short circuits occur in inputs and outputs.

 Cables are securely connected.

 Battery cables are correctly connected to battery terminals. The battery voltage meets the

requirements.

 Cables are properly connected between the UPS and batteries.

 Power cables and signal cables are correctly identified.

 Cables are neatly routed and securely bound.

 Devices are installed and cables are routed in ways that facilitate modification, capacity

expansion, and maintenance.

 The UPS is properly grounded.

 The voltage between the neutral wire and the ground cable is less than 5 V AC.

 The input voltage rang for the mains to start the UPS is 120–280 V AC (or 80–280 V AC

after the UPS powers on). The battery voltage range is (Number of batteries x 10. to

(Number of batteries x 14) V DC.

5.2 Starting the UPS

UPS2000-G-(1 kVA-3 kVA)

User Manual

 In the preset mode, LCD will return to the main page with 10 seconds of no operation.

 If the long backup time model is not connected to an external battery pack, the buzzer

keeps buzzing.

 Charge the batteries used for the first time for 5 hours. Otherwise, the battery discharge

time will decrease.

 The UPS performs a battery self-check automatically once a week. If batteries are faulty,

an alarm is generated.

 If the UPS is connected to the mains, when the battery packs or battery strings connect to

the UPS with long backup time for the first time, you must do a battery self-check

manually, in order to confirm the battery connection is normal. The method is: hold down

the ON/MUTE button on the front panel for 5 seconds, then the UPS transfer to battery

mode to do a shallow discharge test, after 10 seconds it automatically back to line mode.

 The UPS with long backup time provides a charge current of 4 A and the current is not

configurable. If the UPS needs to connect to battery packs or battery strings, the total

battery capacity must exceed 18 Ah. Otherwise, batteries may be damaged. If the capacity

of external battery packs or battery strings to be connected exceeds 40 Ah, it is

recommended that an external charger be purchased to increase the charge current. If an

external charger is not purchased, the charge time will be long.

 The 1 kVA UPS with standard backup time has two built-in batteries, the 2 kVA UPS with

standard backup time have four built-in batteries, the 3 kVA UPS with standard backup

time have six built-in batteries. If the 1 kVA UPS with long backup time needs to connect

to external battery strings, each battery string must consist of three 12 V batteries

connected in series. If the 2 kVA UPS with long backup time needs to connect to external

battery strings, each battery string must consist of six 12 V batteries connected in series. If

the 3 kVA UPS with long backup time needs to connect to external battery strings, each

battery string must consist of eight 12 V batteries connected in series.

 For the UPS with standard backup time, the battery capacity has a fixed value of 9 Ah and

the charge current has a fixed value of 1 A. Set the battery capacity to the total capacity of

all batteries actually connected. Set the battery capacity for the long backup time model

based on site requirements. The default value is 18 Ah. For example, if eight batteries (9

Ah, 12 V) are connected in series to form a battery string, and two of such battery strings

are connected in parallel and then to the 3 kVA long backup time model, set battery

capacity to 18 Ah (9 Ah + 9 Ah). This parameter affects the backup time calculation.

Incorrect setting will cause incorrect display of the backup time on the LCD.

During the setting of UPS parameters, press ON/MUTE for more than 3 seconds. Release the button
