Alarm

Cause

Repair Proposal

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.

Internal fault 2A

•

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.

Bypass

backfeed

Possible cause: Bypass components are faulty.

Measure: Contact Huawei technical support.

Parallel

cables

abnormal

•

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.

Parallel cable

alarm

•

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.

EPO

Possible cause: You have pressed the EPO switch.

Measure: Restore the EPO switch status, clear the alarm, and

restart the UPS.

Insufficient

redundancy

•

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.
