Table 7–1 Fault Codes (Cont.)
Meaning
Detection of output overvoltage.
Output voltage dropped.below specs.
Detection of inverter overcurrent.
Detection of a large variation of the reference
error signal (current reference and actual
current).
Discrepancy between output voltage and
external voltage (bypass, common ac bus)
Inverter zero-sequence overcurrent.
Cross current is abnormal.
Error to close the contactor 52C.
Error to open the contactor 52C.
No answer from contactor 52C during inverter
operation.
Heatsinks temperature exceeds thermal
settings.
Thermal relay activated protection.
Detection of inverter output phase overvoltage.
Detection of zero-sequence overcurrent.
Discrepancy between output voltage and
inverter voltage, or between output voltage
and bypass voltage.
Output voltage is outside of the specified
range.
Contactor 52C failed to open during load
transfer from inverter to bypass.
Load transfer due to overload for over 4 times
within 5 minutes.
No detection of another UPS voltage signal.
