1. Safety and Overview
Safety precautions (In order to ensure the safety, please observe the following)
 Please be sure to read the user’s manual before use.
 Please charge the product for more than 8 hours before using it.
 When the battery has been discharged or the storage period has been more than 3
months, the battery shall be charged for more than 8 hours in time, so as to ensure it
is fully-charged and prevent it from being damaged.
 This product is specially designed for group computers. It shall not be connected with
inductive loads (e.g. motor, refrigerator, etc.). It is not recommended for life
supporting system and other specific major equipments.
 When installing the product, please maintain a distance of more than 50cm away
from the display.
 The normal temperature of the chassis surface will reach about 50℃ during the use
of this product, which is a normal phenomenon.
 Do not use UPS which goes beyond the rated load capacity.
 Do not open UPS case, or it will lead to electric shock or other dangers. If it is
required to conduct an internal overhaul or replace the battery, please deliver it to the
designated maintenance center.
 As internal short-circuit will result in electric shock or fire, any vessel containing
liquids shall not be placed on UPS for fear of electric shock or other dangers.
 When the machine works abnormally, cut off the power immediately, and contact the
supplier.
 Never store or use this product in the following conditions.
1) The place where there is no air convection
2) The place where combustible gas, corrosive substance or a great deal of dust
exists
3) The place where the temperature is extremely high or low (above 40℃ or below
0℃) and the humidity is high (above 90%)
4) The place having direct sun exposure or close to heating equipment
5) The place where violent vibration occurs
6) Outdoor

 In case of fire around UPS, put out the fire with powder fire extinguishers. Using fluid
extinguisher may lead to electric shock.
 Please place the power socket near UPS, so that UPS can be disconnected from the
socket in emergency.
 When it is required to move or re-connect UPS, the AC input power shall be cut off to
ensure UPS stops completely, or the output end may be live which may result in
electric shock.
 The battery life is shortened as the ambient temperature rises. Periodic battery
replacement can ensure UPS works properly and there is enough backup time.
 The battery maintenance shall only be carried out by the personnel having
professional knowledge of batteries.
 Since the dangers of electric shock and short-circuit current exist, the following
warnings shall be observed in battery replacement to avoid electric shock.
1) Do not wear watches, rings or other metal objects.
2) Use insulated tools.
3) Wear rubber shoes and glove.
4) Do not place metal tools or metal parts on the battery.
5) First disconnect the load connected to the battery before removing connecting
terminals of the battery.
6) Do not short-circuit the positive and negative terminals, or it will lead to electric
shock or fire.
7) Do not touch the connecting terminal of the battery. Do not separate the battery
circuit from the input voltage circuit. The danger of high voltage exists between
the battery terminal and ground.
Warning!
The equipment must be grounded. When AC utility power is
connected, the system shall be grounded reliably.
Improper operation will result in huge losses. Please be sure to
operate this product according to the requirements of operation
instructions.

2.4.1 Installation attentions
1. Put UPS in a well-ventilated place and ensure the heat emission holes and fan
peripherals of the chassis meet the ventilation conditions at a distance of
150mm above and keep away from water, combustible gases and corrosives.
2. Turn off the devices which need uninterrupted power supply (such as host
computer), disconnect the power cord from the utility power socket and connect
it to the output socket of UPS connect the devices which do not need to be
connected with UPS to the common utility power socket.
3. Put UPS input plug into the utility power socket (ensure the zero wire and live

3. Check whether the cover has collected too much dust or not.
4. Check whether the input, output and battery cables are firm or not and whether
the cable insulation is good or not.
5. Ensure UPS is well protected against moisture.
6. Start UPS (specifically refer to startup operation).
7. Discharge UPS powered by the battery and other unimportant loads, until the
battery low voltage alarm sounds. During the period, there will be no other alarm.
If any other alarm is triggered, please contact local service center.
8.2 Battery maintenance
This machine adopts sealed lead-acid battery. The service life of the battery
depends on the storage and service environment and battery discharge frequency.
The temperature increase will shorten the service life of the battery rapidly. Even if
the battery is not used, its performance will decrease gradually. It is recommended
to carry out the discharge test once every three months in case of uninterrupted
power supply.
The checking methods of the battery will be introduced as below (the battery
performance will decrease sharply with the approaching of the expiration date, so
the following checking and maintenance methods shall be kept in mind)
1. Connect with the utility power line, start UPS, and charge the battery for more
than 8 hours. Pay attention to the operation condition of the loads connected to UPS.

2. Maintain the load condition, and record the total power. Disconnect UPS input
plug (to simulate the interruption of utility power). UPS enters battery discharge
mode, until it is shut down automatically. And record the discharge time. Keep
the record of initial discharge time for future use.
a) The total load capacity (power consumption) shall be calculated by watts
(W).
b) If the nameplate only states the volt-ampere (VA) value, multiply it by the
power factor (0.8, if not stated) and convert it to watts (W).
c) If only the current (A) value is stated, multiply it by the rated voltage (V)
and then by the power factor, and convert it to watts (W).
3. The battery service life is about 1 – 2 years in normal service conditions. When
the temperature is pretty high and the discharge is conducted frequently, the
battery service life may be 0.5 – 1 year.
4. The battery performance decreases gradually (marked by the discharge time)
as the application period extends. When the discharge time decreases to 80%
of initial value, its performance reduction will be accelerated. Accordingly, the
battery checking time shall be changed to once per month from once half a
year.
5. Battery maintenance of extended runtime model (it is crucial to conduct proper
maintenance for the battery to prevent the precision equipment from being
damaged in case of power outage).
a) Clean the dust and dirt on the battery.
b) Check internal lines of all batteries for any looseness or corrosion. Carry
out the replacement and repair if necessary.
c) Ensure the battery and battery terminals are firmly fastened.

9. Exception Handing
Carry out the self checking according to the following methods in case of abnormal
conditions. If the abnormal condition cannot be eliminated, please contact the nearest
distributor or warranty unit or directly contact our company.
Condition Confirmation and countermeasures
The utility power is normal, while UPS
cannot connect to it
1) Check whether the power cord is loose.
2) Check whether the over-current protector is out.
The utility power is normal, while UPS cannot
start normally. The failure indicator is normally
on, “
!
” icon is normally on, and LCD function
display area displays OFF
1) Check whether the battery wire is connected or
not.
2) Confirm whether the battery is damaged or not.
In utility mode, the buzzer beeps continuously,
“ ” icon blinks, and the machine works in
bypass mode after a while in inverter mode,
the buzzer beeps continuously, “ ” icon
blinks, and the machine is shut down
automatically after a while
Output overload check whether the condition
of overload occurs in UPS load display.
Reduce the load.
UPS cannot power on after the “ON” key is
pressed
1) The “ON” key is pressed too briefly. Press the
“ON” key continuously for more than 3 seconds
to start UPS.
2) Check whether the battery is connected.
3) UPS has internal failure. Please contact the
supplier.
The battery discharge time diminishes
1) The battery has not been fully charged. Keep
UPS connected to utility power persistently for
more than 8 hours to charge the battery again.
2) UPS is overloaded. Check load capacity, and
reduce the load.
3) The battery is aged and the capacity
decreases. Replace the battery. Please
contact the supplier to obtain the battery and
components for replacement.
