When the parallel parameters are
different, this prompt will appear

output
If the user attempts to change certain important settings while the output is active
(output voltage, output frequency, output phase No.), this prompt will appear
Incorrect password, please input again
This prompt will appear when t
he user enters an incorrect Settings password
Operation failed, condition is not met
This prompt will appear when the user attempts to execute a certain operation, but the
necessary condition is not met

Alarm message
Description
Communication fail
Internal
communication
is
abnormal,
please
check
whether
the
communication
cables
are
connect
ed
correctly
or not
Rectifier fault
The rectifier is faulty and is not running
DC/DC fault
The discharger is faulty,
because the bus voltage exceeds the setting range when discharger starts or soft
starts
DC bus abnormal
The inverter is off when DC bus
voltage is faulty. The load will transfer to bypass, if the bypass is available
Charger fault
The battery
charger output voltage is abnormal, and the charger is off
Aux. power fault
The auxiliary power output voltage exceeds the normal range
Input backfeed
Battery mode. The mains relay is shorted and the difference between the mains and battery voltage is le
ss
than the setting range
Inverter fault
The inverter is off when the inverter output voltage and current exceed the setting range. If the bypass is
available, the UPS will transfer to bypass mode, otherwise the system will switch off
Output short
circuit
Check for short circuits between the output cables
Bypass backfeed
Battery mode. The bypass relay is shorted or the SCR is damaged
Output off, vo
ltage is
not zero
The Output is switched off, but the system detects the presence of a voltage at the output terminals
Inverter relay shorted
The inverter relay is short circuited
Parallel No. abnormal
The
on
-
line
parallel
number
is
inconsistent
with
th
e
value
in
the
settings.
Please
check
that
the
parallel
number on the 'Settings' page is the same as the actual on-line number, and that the parallel cables are
normal
Parallel comm fault
The local UPS and its on
-
line frequency configuration is different
or there is a conflict with the parallel
address. Please check that the parallel system parameter setting is the same as the local parameter setting
Parallel cable
connection abnormal
The system has detected that the parallel cables are not secure
