swappable batteries, with the UPS on, the load will not be backed up.
Symptom
UPS will not turn on
UPS operates in battery mode
only, even though there is
normal AC present
The UPS emits a sustained tone
The Site Wiring Fault LED is
illuminated
The Battery On LED is
illuminated, but there
is no output
UPS does not provide expected
backup time with internal
batteries or with a battery pack
Replace Battery LED is
illuminated
UPS occasionally emits a beep
Overload LED is illuminated and
a constant alarm sounds
The Battery On LED is blinking
and the audible alarm is silent
Possible Cause
On/Off/Test button not pushed
Input AC circuit breaker is
tripped
UPS has detected an internal
fault
Incorrect service wiring
The UPS is being controlled via
its computer port.
The batteries may be weak or
at the end of useful service life.
The battery pack’s circuit
breaker may be tripped.
Weak or bad batteries/bad
battery connection
Normal operation
The load has exceeded the UPS’
capacity
The UPS is in either the Buck
mode or the Boost mode
What To Do
Press the On button
momentarily (one beep to
start UPS)
Reset circuit breaker by
pressing the plunger back in.
If the AC circuit breaker trips
after UPS starts up, reduce the
load on the UPS.
Call for service
Have a qualified electrician
correct the service wiring
Disconnect the computer cable
from the UPS and press the On
button momentarily. If UPS
works normally, software has
control of the UPS.
Charge the batteries for 8 hours
and retest. If the backup time
is still less than expected, the
batteries may need to be

CAUTION: Do not open or mutilate batteries. Released
electrolyte is harmful to the skin and eyes and may be toxic.
CAUTION: Although battery system voltages are only 24VDC
and 48VDC, the battery system can still present a risk of
electrical shock. The current capability of a battery is sufficient
to burn wire or tools very rapidly, producing molten metal.
Observe these precautions when replacing the batteries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Do not lay tools or other metal parts on top of batteries.
CAUTION: Replace batteries with the same number and type as
originally installed in the UPS. These batteries have pressure-
operated vents.
