Low-Battery. The UPS is in battery operation and
the battery charge is low.
Note: Runtime is limited in duration. Shut down the system and the load
equipment or restore incoming volt-
age.
Load Is No Longer
Above Alarm Threshold. The load previously exceeded the
alarm threshold and the situation has
been corrected either because the load
decreased or the threshold was
increased. No is corrective action necessary.
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.
Mains Not Available.
Input Freq/Volt Out of
Range. The frequency or voltage is out of
acceptable range for normal
operation. Correct the input voltage to provide
acceptable voltage or frequency.
Min Runtime Restored. The system runtime dropped below
the configured minimum and has
been restored. Additional Battery
Modules were installed, the existing
Battery Modules were recharged, the
load was reduced, or the threshold
was decreased. No corrective action is necessary.
No Batteries Are
Connected. No battery power is available. Check that batteries are inserted
properly.
Number of Battery
Modules Decreased. One or more battery modules were
removed. No corrective action is necessary.

added. No corrective action is necessary.
Replace Batt(s). One or more Battery Modules need
replacement (only applicable with
internal batteries). Refer to the Module Replacement
section for procedures.
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 the load.
Option 4: Decrease the alarm
threshold.
