BYPASS LED ILLUMINATES
The bypass switch has been
turned on manually or through
an accessory. If bypass is the chosen mode of operation, ignore the illuminated LED.
If bypass is not the chosen mode of operation move the bypass switch on the
back of the UPS, to the normal position.
FAULT AND OVERLOAD LED S ILLUMINATE , UPS EMITS A SUSTAINED ALARM TONE
The UPS has ceased sending
power to connected equipment. The connected equipment exceeds the specified “maximum load” as defined in
Specifications section of the Quick Start Guide .
Disconnect nonessential equipment from the UPS to eliminate the overload
condition.
Press the OFF button, then the ON button to restore power to connected
equipment.
FAULT LED ILLUMINATES
Internal UPS fault. Do not attempt to use the UPS. Turn the UPS off and have it serviced
immediately.
REPLACE BATTERY LED ILLUMINATES
Replace Battery LED flashes and
short beep is emitted every two
seconds to indicate the battery is
disconnected. Check that th e battery connectors are fully engaged.
Weak battery. Allow the battery to recharge for 24 hours. Then, perform a self-test. If the
problem persists after recharging, replace the ba ttery.
Failure of a battery self-test. The UPS emits short beeps for one minute and the Replace Battery LED
illuminates. The UPS repeats the alarm every five hours. Perform the self-test
procedure after the battery has charged for 24 hours to confirm the Replace
Battery condition. The alarm stops and the LED clears if the ba tt ery passes the
self-test.
UPS OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE EXISTS
Very high, low, or distorted line
voltage. Inexpensive fuel
powered generators can distort
the voltage. Move the UPS to a different outlet on a different circuit. Test t he input voltage
with the utility voltage display.
D IAGNOSTIC U TILITY V OLTAGE
All five LEDs are illuminated The line voltage is extremely high and should be checked by an electrician.
There is no LED illumination If the UPS is plugged into a properly functioning utility power outlet, the line
voltage is extremely low.
O NLINE LED
There is no LED illumination The UPS is running on battery, or it is not turned on.
The LED is blinking The UPS is running an internal self-test.
