PROBLEM AND/OR POSSIBLE

CAUSE

OLUTION

THE OVERLOAD LED IS ILLUMINATED AND THE UPS EMITS A SUSTAINED ALARM TONE

The UPS is overloaded. The

connected equipment exceeds

the “maximum load,” as de-

fined in Specifications at

www.apc.com.

The alarm remains on until the overload is removed. Disconnect nonessen-

tial equipment from the UPS.

The UPS continues to supply power as long as it is online and the circuit

breaker does not trip; the UPS will not provide power from batteries in the

event of a utility voltage interruption.

If a continuous overload occurs while the UPS is on battery, the unit turns

off output in order to protect the UPS from possible damage.

THE REPLACE BATTERY/BATTERY DISCONNECTED LED IS ILLUMINATED

This LED flashes and short

beep is emitted every two sec-

onds to indicate the battery is

disconnected.

Check that the battery connectors are fully engaged.

Weak battery. Allow the battery to recharge for 24 hours and perform a self-test. If the

problem persists after recharging, replace the battery.

Failure of a battery self-test.

This LED is illuminated and

the UPS emits short beeps for

one minute. The UPS repeats

the alarm every five hours.

Allow the battery to recharge for 24 hours and perform another self-test to

confirm the replace battery condition. If the battery passes the self-test, the

alarm will stop and the LED will clear.

If the battery fails again, it must be replaced. The connected equipment is

unaffected.

THE SITE WIRING FAULT LED ON THE REAR PANEL IS ILLUMINATED (120 V MODEL ONLY)

The UPS is plugged into an

improperly wired utility power

outlet.

Wiring faults detected include missing ground, hot-neutral polarity reversal,

and overloaded neutral circuit.

Contact a qualified electrician to correct the building wiring.

THE INPUT CIRCUIT BREAKER TRIPS

The UPS is overloaded. Reduce the load on the UPS by unplugging equipment. Reset the breaker.

THE AVR BOOST OR AVR TRIM LEDS ARE ILLUMINATED

Your system is experiencing a

period of low or high voltage.

Have qualified service personnel check your facility for electrical prob-

lems. If the problem continues, contact the utility company for further as-

sistance.

THERE IS NO UTILITY POWER

There is no utility power and

the UPS is off.

120/208/230 V models only: Use the Cold Start feature to supply power to

the connected equipment from the UPS battery.

Press the button for one second and release. The UPS will beep briefly.

Press and hold the

button again for about three seconds. The unit will

emit two beeps. Release the button during the second beep.
