Battery test
active Battery test is on.
Battery
discharging
Batteries are discharging after a mains failure.
Battery test
failure
Batteries failed in the battery test.
Input voltage high Input mains voltage is higher than its upper limit.
Input voltage low Input mains voltage is lower higher than its lower limit.
Input sequence
wrong Phase sequence of input mains voltages is not OK
Input not
synchronized Frequency of input mains voltage is beyond the frequency range for input
operation or input mains voltage is very low.
DC not equal to
input voltage Rectified input voltage is not equal to DC bus voltage.
DC voltage high
DC bus voltage is higher than its upper limit.
DC voltage low DC bus voltage is lower than its lower limit may mean that the battery is
empty during battery operation.
Ambient
temperature high Ambient temperature exceeds its upper limit.
Junction
temperature high Junction of IGBT temperature exceeds its upper limit.
Heatsink
temperature high Heatsink temperature exceeds its upper limit.
Output voltage
failure
Output voltage is beyond its limits
Output short
circuit Short circuit at the output.
Generator mode
active
Generator friendly operation is activated.
Emergency power
off active
Emergency stop is activated.
Manual bypass
active
Manual bypass switch is “ON”.
Output open
circuit Output circuit breaker is at “0” position (just for parallel UPSs)
N number failure Parallel system alarm. If the UPS number in parallel is less than the pre-
adjusted N number, than this alarm appears.
Redundancy lost Parallel system alarm. The total load is more than the redundancy load. The
formula is Load % x (N+1) / N > 100
