The voltage
of each
battery is
lower than 5
V (when the
UPS is
started).
This alarm is
generated
because there
are more
batteries than
required. The
impact is as
follows:
● If batteries
are connected
before the
startup, the
UPS fails to
start.
● If batteries
are connected
when the UPS
is running,
the UPS
transfers to
bypass mode.
● Possible cause: The
actual number of
batteries does not
meet requirements.
Measure: Check
that the actual
number of batteries
meets requirements.
● Possible cause: The
mains is abnormal,
and the batteries
are overdischarged.
Measure: Connect
to the mains in
non-battery test
state.
