2.3 Working Principles
When the mains is normal, the input of N1C L-Series(1-3kVA) UPS converts into the ±360V steady
DC voltage through PFC, which supplies power for DC/AC inverter to output steady 220V AC and
charges battery at the same time. When the mains is abnormal, the battery will boost into the ±360V
DC voltage for DC/AC inverter through DC/DC.
The working principles of N1C L-Series(1-3kVA) UPS is as shown in Figure2-13. The DC/AC inverter
adopts half bridge structure and the DC/DC boost adopts the push-pull circuit or boost circuit. PFC is
the correction circuit for active power factor.

− When using battery for the first time, start UPS to charge b attery for ten hours. During char ging,
you still can use UPS. If UPS and batte ry are pow er down sim ultaneously, the discharging time
of battery may be lower than standard this time.
− Generally, charge and discharge battery once every four to six months. Discharging battery until
UPS turns off. Then charge them. The charging time should be no less than ten hours.
− In high-temperature areas, charge and discharge battery once every two months. The charging
time should be no less than ten hours.
− If battery have not been used for a long time, charge and discharge them once every three
months. The charging time should be no less than ten hours.
Clean battery shells by water-dipped cloth. Oil and organic solvents, such as petrol and diluents
are prohibited.
To avoid explosion, keep battery far away from fire sources and devices that easily generate
sparks.
When using the battery pack connected with UPS, check whether charger is OK regularly, which
is to avoid battery on the overcharging status or incomplete charging status. It should avoid over
discharging battery. After discharging, it should charge battery completely (The time should be
less than 24h). It is prohibited that the incomplete charging battery discharges again, which will
reduce the battery capacity, even damage battery.
Press " " button to shut down UPS which is to avoid battery discharging for a long time after
mains powers down. If UPS stops working for a long time, it should charge and discharge battery
periodically, which is to avoid battery damage for self-discharge.
5.3 Replacing Battery Announcements
Don't put battery into fire to avoid explosion.
Don't open or dismantle battery. The inner electrolyte is harmful to our skin and eyes.
Recycle battery according to the instructions appropriately.
Consult professionals for replacing battery.
A new battery should be with the same capacity, model, and manufacturer as the replaced one.

After starting UPS, if UPS works abnormally, please refer to Table5-1 to find possible reason.
Meanwhile, check whether the fault is caused by external environment, such as temperature, humidity
are not accordance with requirements or UPS is overload.
Table5-1 only includes some simple diagnosis. If the diagnosis is not clear, or not sufficient to solve
problem, please contact with local agency or dealer to deal with.
Table5-1 Troubleshooting
No. Phenomenon Possible reasons
1
The mains is normal. When starting
UPS, it can output 220V AC. But
UPS works in the b attery inverting
status, and the buzzer beeps
intermittently.
Make poor connection in the contacts of grid feeding
circuit or sockets, which will lead to power input is
not expedite.
2
When
starting UPS, it can output
220V AC. But UPS works in the
bypass status (" " indicator is
always on.)
(1) The load exceeds the rated output cap
acity of
UPS. It should reduce load or select UPS with more
larger output capacity.
(2) It is normal that shock from load startup leads to
turn into bypass mode temporarily
and recovery
automatically
3
After starting UPS, output is normal.
But when starti
ng load, UPS will
stop output immediately.
(1) If UPS is serious overload or output is short
circuit, it should reduce load to proper or find reason
of short circuit. The com m on reason i s that the out put
multi-tap is short circuit, or the input is short circuit
after device is damaged,
(2) If you do not follow the startup s equence that is
"high power device →
small power device" to start
load, restart UPS. When UPS works steadily, restart
load following the sequence.
4
After starting UPS, UPS works
normally. After a while, UPS will
shut down automatically.
