the UPS off. ⓫
AVR TRIM - UPS is compensating for a high utility
input voltage.
❸
POWER ‘ON/OFF’ BUTTON - Button to
turn the UPS on or off. ⓬
OVERLOAD - The power demand from the load
(connected equipment) has exceeded the
capacity of the UPS. A sustained alarm tone is
also emitted.
❹
ESCAPE BUTTON - Button to exit a sub-
menu. ⓭
LOAD CAPACITY - The load is indicated by the
number of sections illuminated, one to five. Each
bar represents 20% of the load.
❺

selection on the menu. ⓮
BATTERY CHARGE - The battery charge level is
indicated by the number of sections illuminated.
When all five blocks are illuminated, the UPS is at
full charge.
❻

though menu options. ⓯
SYSTEM FAULTS - The system has a fault. For
some models, a fault number will appear on the
display interface. See “UPS Troubleshooting” on
page 3
❼
ONLINE - UPS is supplying utility power
to the connected equipment. If not lit, the
UPS is either supplying battery power or
not turned ON. ⓰
DISPLAY SCREEN – Displays important
information about the UPS and connected
equipment.
❽
ON BATTERY - UPS is supplying battery
backup power to the connected
equipment. UPS will beep four times
every 30 seconds.
❾
REPLACE BATTERY - UPS has failed a self-test, or the battery is bad. UPS will also produce short beeps
for a minute.
BATTERY DISCONNECTED - Flashes to indicate the battery is disconnected. UPS will beep every two
seconds.

UPS Troubleshooting:
NOTE: Troubleshooting procedures may differ depending on UPS model.
UPS will not turn on

Power/Test button not pushed. Press the Power/Test button once to power the UPS and the load.
UPS not connected to AC power supply. Check that the power cable from the UPS to the wall outlet is securely
connected.
UPS input circuit breaker tripped. Reduce the load on the UPS by unplugging equipment. If available, reset
the circuit breaker (on back of UPS): for the plunger-type, press the
plunger back in. For the toggle-type, flip the switch to the ‘ON’ position.
Very low or no utility voltage. Check the AC power supply to the UPS with a multimeter or table lamp. If the meter reads a voltage below the UPS’s acceptable operating range,
or the light bulb is dimly lit, have the utility voltage checked.
Battery not connected properly. Confirm the external Battery Connector / Disconnect, or internal connections. A connectormay appear to be connected, additional
insertion force may be required to firmly seat any loose connections.
UPS will not turn off
Internal UPS fault. Do not attempt to use the UPS. Unplug the UPS and have it serviced
immediately.
UPS operates on
-
battery although normal line voltage exists
UPS’s input circuit breaker tripped. Reduce the load on the UPS by unplugging equipment and reset the circuit breaker (on the back of UPS): for the plunger-type, press the
plunger back in. For the toggle-type, flip the switch to the ‘ON’ position.
Very high, low, or distorted utility line voltage.
Generator sets with poor line regulation.
Move the UPS to a different outlet on a different circuit. Test the input
voltage with the utility voltage display. If acceptable to the load, reduce
the UPS’s sensitivity. See User’s Manual for procedures.
UPS beeps occasionally

Normal UPS operation. None. The UPS is protecting the load.
UPS does not provide expected backup time
The UPS’s battery is weak due to a recent
outage or is near the end of its service life.
Allow the UPS time to charge the battery, batteries require recharging
after extended outages. Also, batteries wear faster when put into service
often or when operated at elevated temperatures. If the battery is near the
end of its service life, consider replacing the battery even if the ‘replace
battery’ indicator is not yet lit.
The UPS is overloaded. Check the UPS’s load display. Unplug less needed equipment, such as
printers or reconsider the sizing requirements of the setup – a larger VA
capable UPS might be required.
Front panel indicators flash sequentially

The UPS has been shut down by remote control. None. The UPS will restart automatically when utility power returns.
All indicators are lit
(or Fault LED & message)
and UPS emits a constant beeping
sound
Internal UPS fault. Do not attempt to use the UPS. Turn the UPS off and have it serviced
immediately.
All indicators are off and UPS is plugged into wall outlet
The UPS is shut down and the batteries are
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.
The replace battery light is lit
Weak batteries. Perform an additional self-test to see if the warning clears.

Replacement batteries not connected properly. Confirm the battery connections.
The display has a Site Warning Fault message
Wiring faults detected includemissing ground,
hot-neutral (polarity reversal), and overload
neutral circuit.
If the UPS indicates a site wiring fault, have a qualified electrician inspect
the building wiring.
