Condition PowerView Message Reason Corrective Action
Redundancy is below
alarm threshold.
Actual power module redundancy
has fallen below the user-specified
redundancy alarm threshold. The
power module(s) failed or the load
has increased.
Option 1: If possible, install
additional power modules.
Option 2: Decrease the load.
Option 3: Use the PowerView
to decrease the redundancy
alarm threshold.

Runtime is below alarm
threshold.
The predicted runtime is lower
than the user-specified for the
minimum runtime alarm threshold.
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: Decrease the load.
Option 4: Use the PowerView
to decrease the minimum
runtime alarm threshold.

Bypass is not in range
(either freq or voltage).
The frequency and/or voltage are
out of acceptable range for
bypass. This message occurs
when the UPS is online and the
bypass mode is unavailable. The
system may start on-battery.
Option 1: Decrease the
sensitivity to input frequency.
(Startup>Setup>OutputFreq)
Option 2: Correct input
voltage to provide acceptable
voltage and/or frequency.
Bypass contactor stuck in
bypass position.
The UPS is positioned in the
bypass position and cannot go on-
line.
Bypass contactor stuck in
on-line position.
The UPS is positioned in the on-
line position and cannot go to
bypass.
UPS in bypass due to
internal fault.
The UPS has transferred to
bypass mode because a fault has
occurred.
Call your contract service
provider or APC Technical
Support.
UPS in bypass due to
overload.
The load exceeded the system
power capacity. The UPS has
switched to bypass mode.
Option 1: Decrease the load.
Option 2: If possible, add
power modules to the system.
Bypass
System is in Maintenance
Bypass.
The UPS is in bypass because the
maintenance bypass switch is in
the on position.
No corrective action
necessary.
