Maintenance
circuit
breaker ON
Possible cause: The maintenance bypass switch is ON during
UPS maintenance.
Measure: Set the maintenance bypass switch to OFF after
maintenance.
Possible cause: The mains has experienced a transient high
voltage.
Measure: Rectify the fault and restart the UPS.
Possible cause: The output supplies power to special loads
such as the inductive and rectification loads.
Measure: Check that the load types are supported by the
UPS.
Possible cause: The hardware is damaged.
Measure: Contact Huawei technical support.
Parallel
settings
abnormal
Possible cause: The single UPS or parallel system settings are
inconsistent with the system cable connections.
Measure: Check the single UPS and parallel system settings.
Possible cause: Bypass components are faulty.
Measure: Contact
Huawei technical support.
Possible cause: The parallel cables connected are loose.
Measure: Check that parallel cables are securely connected.
Possible cause: Parallel cables are damaged.
Measure: Replace the parallel cables.
Possible cause: The parallel cables connected are loose.
Measure: Check that parallel cables are securely connected.
Possible cause: The parallel cables are damaged.
Measure: Replace the parallel cables.
Possible cause: You have pressed the EPO switch.
Measure: Restore the EPO switch status, clear the alarm, and
restart the UPS.
Possible cause: The number of redundant UPSs is too large.
Measure: Reduce the number of redundant UPSs or set the
UPS to work in non-redundant mode.
Possible cause: The load exceeds the rated loading capacity
of the UPSs that are working in the parallel system.
Measure: Lower the load or replace the UPS with a UPS
with a larger capacity.
Parallel
parameter
inconsistency
Possible cause: Parallel parameters are inconsistent between
UPSs in the parallel system.
Measure: Manually synchronize parallel parameters.
