Description
The UPS is working normally.
The UPS is in bypass mode.
The Utility is blackout or abnormal. The UPS is in backup
mode.
The UPS is in backup mode, and the battery voltage is closed
to the terminative limit. (The battery voltage is lower than
220V.)
The bypass is abnormal (frequency, phase), and the output
frequency will follow the rating.
Performs the battery test. The battery voltage is lower than the
default value.
Description
The communication of module is abnormal.
During installation of the parallel redundancy, the parallel
communication is abnormal.
The loading is over rated output of the UPS.
The module fails and the UPS is shut down.
The module has errors, but the UPS can still function
normally.
Urgently power off the UPS.
The UPS transfers to manual bypass mode.
The temperature is too high.
The output voltage is too high or too low.
Overdue for battery replacement (Compared with system
setup.)
