NO Abnormal phenomena Possible reason
4
The UPS output normally
after startup, but once turn
on load, the UPS stop
outputting
immediately.
1. The UPS is serious overload or the output circuit is short-
circuit. It is necessary to reduce load to proper capacity or find
the reason of short-circuit. Common reason is output socket is
short circuit or input short circuit caused by device damage.
2. The load is not started according to the sequence from large
power device to small power device. You should restart the
UPS. After the UPS run stably, start the load according to the
sequence from large power device to small power device.
5
The UPS work normally
after startup, but some
time later, the UPS shut
down automatically.
At the status of battery supply power, the battery is runs out and
system protects for battery under-voltage, the UPS shut down
automatically. This phenomenon is normal. Once mains normal,
system will start and charge battery automatically.
Warning: if the battery stays in under-voltage status for long time,
it will influence the battery service life. After battery under-
voltage protection, if mains cannot recover in a long time, please
disconnect the battery breaker to protect battery and
restart the UPS and fully charge the battery once mains recovers.
6
After startup and work for
a long time, buzzer long
beeps and the touch
screen shows battery
low-voltage.
The grid voltage is too low, and the UPS works in battery
inverting status, finally, the battery is under-voltage and causes
under-voltage protection.
7
When there is mains, the
UPS output normally,
when there is no mains,
the UPS is with no output.
1. Battery fault or the battery group is serious damaged.
2. Charger fault. The battery cannot be charged and causes
battery energy insufficient.
3. Battery wire is not well connected or the contact of wire
terminal is not good.
4. Battery breaker is not closed.
5. After serious overload, the UPS is not restarted, which
causes the UPS stay in bypass output status.
