Explanation
The rectifiers could not start within
specified time due to low DC-bus
voltage.
DC-bus voltage exceeds the
maximum voltage.
DC-bus voltage is lower than the
minimum value.
DC-bus voltage is not balanced
DC-bus voltage changes too fast.
PFC current is higher than the
maximum current.
The temperature in UPS is higher
than 85°C. At this time, the UPS is
off.
Battery SCR is short circuited.
Inverter voltage cannot reach
desired voltage within specified
time.
Inverter voltage is too high.
Inverter voltage is too low.
R phase inverter output is short
circuited
T phase inverter output is short
circuited
T-R inverter output is short circuited
R phase inverter output negative
power is beyond the range.
T phase inverter Output Negative
Power is beyond the range.
Inverter relay or STS is open.
Inverter relay or STS is short
circuited.
