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.

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.

If the long backup time model is not connected to an external battery box, 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 boxes 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 boxes 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.
电池节数不可设。
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
when you hear a beep sound to select the previous option. During the setting of UPS parameters, press
SELECT for more than 3 seconds. Release the button when you hear a beep sound to select the next
option. During the setting of UPS parameters, press OFF/ENTER for more than 3 seconds to confirm
the setting.
