Low
lithium
battery
level
Minor
The
battery
voltage or
SOC rises
above the
alarm
threshold.
Communicati
on is normal,
but the SOC
is lower than
20%.
Communicati
on is
abnormal,
and the
battery
voltage falls
to 47 V DC.
The battery
level is close to
the cutoff
threshold. If
there is no
mains input,
the system will
shut down
after working
for a period of
time.
Possible cause: The
battery charge level
is low.
Measure: Charge
the battery.

Abnorma
l mains
voltage
Minor
The mains
voltage
input
recovers.
● The mains
is
disconnect
ed or fails.
● The mains
input
voltage
harmonic
exceeds
10%
(square
wave
input is
not
supported
).
● The mains
frequency
change
rate
exceeds
the phase
lock rate
defined in
the
specificati
ons (2
Hz/s for a
single UPS
and 1
Hz/s for a
parallel
system).
The system
cannot work in
normal mode.
If this alarm is
generated in
normal mode,
the system
transfers to
battery mode.
Check whether the
mains voltage input
is normal. If the
circuit is faulty,
send the device to
the maintenance
center.
