No. Phenomena
Possible Reason
5
After starting, the
UPS works normally,
but some time later,
the UPS shut down
automatically.
In the status of battery supply power, the
battery is protected for low-voltage caused
by discharging, the system shut down
automatically. The phenomenon is normal.
Once the mains recover, the system will start
automatically and charge for the battery.
Warning: If the battery stays in low-voltage
for long time, it will influence the life span
of battery. After low-voltage protection for
battery, if the mains cannot recover for
long time, it is necessary to disconnect the
battery switch to protect the battery, and
restart the UPS when mains normal, and
charge for the battery.
6
After the UPS start to
work for a while, the
buzzer beeps intermit-
tently.
The voltage of grid is too low, and the UPS
works in battery inverting status, finally, it
causes the battery low-voltage protection.
7
When mains normal,
the UPS outputs
normally, when mains
failure, the UPS is
without output.
• Battery fault or the battery group is serious
damaged.
• Charger fault. The charging for battery
cannot be done, which causes the electric
quantity of battery is not enough.
• Battery wire connection is bad or the
connection of terminal is bad.
• The battery switch is not closed.
• After serious overload, the UPS is not re-
started, which causes the UPS always stay
in bypass output status.
8
The buzzer beeps con-
tinuously, inverter fault
and the UPS turn to
bypass status to supply
power.
• Overload or output is short-circuited, the
UPS shuts down to protect automatically.
• Drive or power tube is fault.
• Main controlling board is fault.
• DC fuse is open-circuit.
