Troubleshooting
Problem and Possible Cause
Solution
The Back-UPS will not turn on.
The Back-UPS is not connected to AC power,
there is no AC power available at the wall
outlet, or the AC power is experiencing a
brownout or over voltage condition.
Make sure the power cord is securely connected to the wall
outlet, and that there is AC power available from the wall
outlet. Where applicable, check that the wall outlet is
switched on.
The Back-UPS is on, the POWER button alternated green-red and the unit emits a constant tone
• The battery is disconnected.
• The battery is near the end of useful
life and should be replaced.
• Remove AC power and refer to the section “Connect
the Battery” on page 2.
• Refer to the section “Battery Replacement” on page
8 for details.
Connected equipment loses power
A Back-UPS overload condition has occurred.
Remove all nonessential equipment connected to the
outlets. One at a time reconnect equipment to the Back-
UPS. Charge the battery for 24 hours to make sure it is
fully charged. If the overload condition still occurs, replace
the battery.
The Back-UPS battery is completely
discharged
Connect the Back-UPS to AC power and allow the
battery to recharge for eight hours.
Connected equipment does not accept the
step- approximated sine waveform from the
Back- UPS.
The output waveform is intended for computers and
peripheral devices. It is not intended for use with motor
driven equipment.
The Back-UPS may require service.
Contact SEIT Technical Support for more solutions.
The POWER button is green and flashes twice every 2 seconds.
The Back-UPS is operating on battery
power.
The Back-UPS is operating normally on battery power.
At this point the user should save all open files, and
shutdown the computer. When AC power is restored the
battery will recharge.
The POWER button flashes green in rapid succession.
The Back-UPS battery has approximately two
minutes of remaining runtime.
The battery is near a total discharge state. The user should
save all open files, and shutdown the computer. When AC
power is restored the battery will recharge.
The Building Wiring Fault LED is red
The building wiring presents a shock hazard
that must be corrected by a qualified
electrical.
Do not operate the Back-UPS. Call a qualified electrician
to correct the building wiring fault.
The Back-UPS has an inadequate battery runtime
• The battery is not fully charged.
• The battery is near the end of useful life and
should be replaced.
Leave the Back-UPS connected to AC power for eight
hours while the battery charges to full capacity.
As a battery ages, the runtime capability decreases. See
Troubleshooting to order replacement batteries.
The alarm is on with a constant tone; outlets are normal but POWER button is not bright.
The UPS is on AC power but the power of the
connected equipment exceeds the rated power
of the UPS. If a power disruption is to occur at
any moment the UPS may not be able to
power the connected equipment. Power to the
outlets will be uninterrupted as long as AC
power is present.
Disconnect devices from the UPS until the load is less than
the rated output of the UPS.
The alarm is beeping (every 0.5 second) and POWER button is flashing.
The UPS have over temperature on battery
mode.
Save all open files, and shut down the computer. When
AC power is restored, the battery will recharge.
The alarm is on with a constant tone and the UPS is off.
The UPS was on battery and the connected
load exceeded the rated load of the UPS.
Turn off the UPS. Disconnect all devices. Turn on the UPS
and reconnect the devices one at a time.
