Impact on the System
Transfer to an unstable side
is not allowed.
N/A
Transfer to bypass mode is
prohibited. If the bypass is
supplying power, the UPS
transfers to another working
mode.
The monitoring module
cannot monitor the digital
signal processor (DSP) of the
power module.
A Alarm Handling
Repair Proposal
Measure: Restore the EPO
button status. Start the UPS
after the alarm is cleared.
Possible cause: The output
transfer times within 30
minutes exceed the
configured value (3 by
default).
Measure: Restart the UPS
after the alarm is cleared.
Possible causes:

The configured number
of redundant UPSs
exceeds the maximum
allowed value.
 The load exceeds the
rated loading capacity
of the requisite UPSs in
the parallel system.
Measures:
 Reduce the number of
redundant UPSs or set
the system to be
non-redundant.
 Reduce the load or
replace the UPS with a
larger-capacity UPS.
Possible cause: The ECO
input is abnormal.
Measure: Check whether
the ECO input voltage or
frequency exceeds the
configured range. If yes,
change the range or wait
until the bypass input
recovers.
Possible causes:
 The communications
cable is faulty.
 An internal fault occurs
in the UPS.
