Redundancy Has Been
Lost
The UPS no longer detects redundant
power modules. One or more power
module(s) have failed, or the load has
increased.
Option 1: If possible, install
additional power modules.
Option 2: Replace failed modules.
Refer to Module Replacement Section
for procedures.
Option 3: Reduce the load.
Redundancy Is Below
Alarm Limit
Actual Power Module redundancy has
fallen below user-specified
redundancy alarm threshold. At least
one Power Module has failed or the
load increased.
Option 1: If possible, install
additional Power Modules.
Option 2: Replace failed modules.
Refer to Module Replacement Section
for procedures.
Option 3: Reduce the load.
Option 4: Use display interface to
change alarm limit.
Runtime Is Below Alarm
Threshold
The predicted runtime is lower than
the user-specified minimum runtime
alarm threshold. Either the battery
capacity has decreased, or the load
has increased
Option 1: Allow the battery modules
to recharge.
Option 2: If possible, increase the
number of battery modules.
Option 3: Reduce load
Option 4: Decrease alarm threshold.
Load Power Is Above
Alarm Limit
The load has exceeded the user-
specified load alarm threshold
Option 1: Use the display interface to
raise the alarm threshold.
Option 2: Reduce the load.
Load Is No Longer
Above Alarm Threshold
The load exceeded the alarm
threshold and the situation has been
corrected either because the load
decreased or the threshold was
increased.
No corrective action necessary
