No Power Modules Detected No power modules are available. Option 1: Ensure that the power
modules are properly installed, the
two fastening screws are tight, and
the locking latch is engaged.
Option 2: Check for other
communication alarm messages in
the log.
Not Synchronized Fault System cannot synchronize to AC
line and bypass mode may not be
available.
Option 1: Decrease the sensitivity
to input frequency.
Option 2: Correct the input
voltage to provide acceptable
voltage/frequency.
Output Voltage Not In Range The output voltage is not within the
specied range.
Evaluate the threshold setting.
If necessary, adjust it for your
situation. Contact Schneider Electric
Customer Support (see the back
cover).
Overload The load has exceeded the system
power capacity.
Option 1: Decrease the load.
Option 2: Add a power module to
the system.
Power Failure The input voltage is not acceptable
for normal operation.
Contact Schneider Electric Customer
Support (see the back cover).
Power Module Fault A power module has failed and
requires replacement.
Replace power module. See
“Replace a Power Module“.
Redundancy Alarm Actual power module redundancy
has fallen below user-specied
redundancy alarm threshold. At
least one power module has failed,
or the load has increased.
Option 1: If possible, install
additional power modules. See
“Replace a Power Module“.
Option 2: Replace failed modules.
See “Replace a Power Module“.
Option 3: Reduce the load.
Option 4: Change alarm limit.
Redundancy Lost The UPS no longer detects redundant
power modules. One or more power
modules have failed, or the load has
increased.
Option 1: If possible, install
additional power modules. See
“Replace a Power Module“.
Option 2: Replace failed modules.
See “Replace a Power Module“.
Option 3: Reduce the load.
Option 4: Change alarm limit.
Redundant Intelligence Module
Fault
The redundant intelligence module
has failed and requires replacement.
Contact Schneider Electric Customer
Support (see the back cover).
Redundant Intelligence Module in
Control
The main intelligence module has
failed, and the redundant intelligence
module is functioning as the primary
intelligence module.
Contact Schneider Electric Customer
Support (see the back cover).
Replacement Battery Needed One or more battery units needs to
be replaced.
Replace battery unit(s). See
“Replace a Battery“.
Runtime Alarm The predicted runtime is lower than
the user-specied minimum runtime
alarm threshold. At least one battery
module has failed or the load has
increased.
Option 1: Install additional battery
modules. See “Replace a Battery“
Option 2: Replace failed battery
modules. See “Replace a Battery“
Option 3: Reduce the load.
Option 4: Change alarm limit.
Site Wiring Fault There is a problem with the phase
rotation or a phase is missing in the
input voltage to the UPS.
Contact the certied electrician that
installed the system.
Static Bypass Switch Module Fault The static bypass switch module has
failed and requires replacement.
Contact Schneider Electric Customer
Support (see the back cover).
