• Recycle the battery according to the relative illustration on the battery.
• Do not put the battery into fire, to avoid explosion.
• Do not open or disassemble the battery, as the inner electrolyte is harmful for the skin and eyes.
7.4 Trouble shooting
7.4.1 Common abnormal phenomena diagnosis
If the UPS works abnormally after start, please refer to Table 7-1 to find possible reason. Meanwhile, check
whether the fault is caused by external environment, such as temperature, humidity is not in accordance with
the requirement or overload.
Table 7-1 only includes some simple diagnosis. If the diagnosis is not clear, or not sufficient to solve the
problem, please contact the local partner.
Table 7-1. Trouble shooting
No.
Abnormal phenomena
Possible reason
− Generally, the battery needs to be charged and discharged every 4 to 6 months. First, discharge till
battery low-voltage alarm and then charge the battery. The charge duration of each time cannot be
less than 24 hours.
− In high temperature area, the battery needs to be charged and discharged every 2 months and the
charge duration of each time cannot less than 24 hours.
− If the battery is not used for a long time, then the battery needs to be charged every 3 months and the
charge time cannot be less than 24 hours.
• Clean battery shells using water-dipped cloth. Oil and organic solvents, such as petrol and diluents
are prohibited.
• To avoid explosion, keep batteries far away from fire sources and devices that generate sparks.
• To avoid over-discharge the battery during use:
-Fully charge the battery immediately after discharge (24 hours at least) and then the battery can
be discharged again. It is strictly forbidden to discharge the not fully charged battery, or, it will
result in decrease of the battery capacity or even damage the battery.
• To avoid battery discharging for too much time after mains power outage, disconnect the battery
breaker when the UPS is not in use.
7.3 Announcements for battery replacement
• Dangerous voltage may exist in the battery terminal and grounding terminal, before touching, please
measure if there is dangerous high voltage, to avoid hazards to human safety. It is strictly
forbidden to touch the two wiring pillars or the bare end of the battery.
• The battery should be replaced in whole group, do not use the new battery and old battery together.
• A new battery should be with the same capacity, model and manufacturer as the replaced one.
The battery with different capacity, different type and different manufacturer battery is strictly
forbidden to be used together.
Mains normal, but UPS works
in battery inverting status, the
buzzer beeps intermittently.
After installation, close breaker
or switch off power supply, it
will or trip off.
After startup, the UPS outputs
230 V AC power, but the UPS
works in bypass status.
Each connection point, socket of grid feed circuit is not so
good, which causes the AC power supply input unblocked.
The three-phase input wires are wrongly connected, such as
neutral wire and ground wire or live wire and grounding
(case) is wrongly connected or the three-phase output wire is
wrongly connected.
1. The load is too large and exceed the rated output capacity
of the UPS. The load needs to be reduced or select a UPS
with larger output capacity.
2. If it is temporary bypass caused by the impact of load
startup, and it can recover to normal automatically, that
is normal.
