Table 4-4 Alarm Messages (Continued)
MESSAGE DESCRIPTION
Battery voltage abnormal
When battery is connected, the system checks that the battery voltage exceeds the normal setting range. Check that
the battery terminal voltage exceeds the normal range
No battery Check the battery and battery cables connection
Battery test fail
The battery low voltage is detected when the battery has manual or periodical self-test. Battery replacement is
recommended
Battery overtemp
Battery ambient temperature too high. Check that the battery ambient temperature is higher than setting value 40 ~ 60
°C (default: 50 °C )
Fan fault At least one fan is faulty. Check that the fan is blocked or the cables connection is loosened
System overtemp
Internal heat sink temperature too high, and the inverter is o. Only each module heat sink temperature decreased to the
setting value can you silence the alarm. The system can automatically start after overtemperature fault is solved.
If overtemperature, please check:
Ambient temperature too high or not
Dust is blocked or not
Fan fault or not
Inverter overload
Inverter load capacity is larger than the rated value, overload delay time is up, inverter shuts down. If bypass is available,
the system will transfer to the bypass mode, otherwise the output is failure. Check that the actual inverter load capacity, if
overloaded, just reduce the load capacity, and the system will transfer to the inverter mode after ve seconds with alarm
cleared
Bypass overcurrent The bypass current exceeds the rated value.
Bypass abnormal
Maybe caused by bypass voltage and frequency outside of range, bypass power-o and incorrect bypass cables
connection.
Check that the bypass voltage and frequency are within the setting range.
Check the bypass cables connection
Bypass abnormal in ECO
mode
The ECO mode is available, and the bypass voltage and frequency are outside of the setting range. Check that the bypass
input voltage and frequency are within the setting range
Output LPE short
The output and enclosure are shorted. Check whether the output cables connection and the enclosure are shorted or
not
Output pending Remote shutdown is enabled, and the system will be o
Output disabled
The system is in standby state, and the dry contact shutdown is enabled. Check whether the shutdown dry contact is
enabled or not
On maintenance bypass The dry contact in maintenance bypass state is activated
Battery mode The UPS is on battery, and the inverter starts
Bypass mode The UPS is on bypass
System overload
The parallel system load capacity is larger than the max. load capacity output by parallel sets. Conrm the parallel system
load capacity, if overloaded, just reduce it
Loss of redundancy After the parallel redundancy is enabled, the system load capacity is larger than the rated load of (online set minus one)
Load sharing abnormal Load sharing is abnormal in parallel system
System parallel settings
sync
Check that parallel setting parameters of each unit are the same
Local parallel settings async Check that the Settings page is the same between this local unit and other units
REPO Shutdown caused by the REPO terminal Normally Closed contact open
System battery low pre-
warning
In parallel system, all the devices powered by the battery inverter have battery low voltage pre- warning
Battery test started The battery periodic self-test and manual self-test started
