UPS is plugged into wall outlet and only the battery charge bar graph is lit.
• The UPS is shut down and the
battery is discharged from an
extended outage.
None. The UPS will return to normal operation when the power
is restored and the battery has a sufficient charge.
Replace battery light is lit and the UPS beeps for one minute every five hours.
• Weak batteries.
Charge the batteries for 24 hours and perform self-test (see
Self-Test, page 9) to see if it clears.
• Bad or expired battery.
Replace the batteries. Refer to Replacing the Battery, page 15.
Replace battery light flashes, battery charge bar graph is off, and the UPS beeps continuously.
• Battery not connected properly.
Check that the battery connector is fully engaged.
Some or all front panel indicators are flashing.
• Internal UPS fault or battery charger
failure.
Do not attempt to use the UPS. Turn the UPS off and have it
serviced immediately.
With the warning interval setting shown above, the battery graph flashes, and the UPS operates
normally when the battery capacity is insufficient to give the full warning time that the unit is set
for. The table bellow shows all conditions that could be interpreted as “flashing”.
