BYPASS AND OVERLOAD LEDS ARE LIT
;
 UNINTERRUPTIBLE POWER SUPPLY EMITS A SUSTAINED 
ALARM TONE
 
The uninterruptible power sup-
ply is overloaded. The con-
nected equipment is drawing 
more VA or more watts than 
the uninterruptible power sup-
ply can sustain. 
The connected equipment exceeds the specified maximum load. 
The alarm remains on until the overload is removed. Disconnect nonessen-
tial equipment from the uninterruptible power supply to eliminate the over-
load. 
The uninterruptible power supply continues to supply power as long as it is 
online and the circuit breaker does not trip; the uninterruptible power sup-
ply will not provide power from batteries in the event of a utility voltage 
interruption. 
If a continuous overload occurs while the uninterruptible power supply is 
on battery, the unit turns off output in order to protect the uninterruptible 
power supply from possible damage. 
BYPASS LED IS LIT
 
The bypass switch has been 
turned on manually. 
If bypass is the chosen mode of operation, ignore the lit LED. 
If bypass is not the chosen mode of operation, move the bypass switch on 
the back of the uninterruptible power supply to the normal position. 
FAULT AND OVERLOAD LEDS ARE LIT
;
 UNINTERRUPTIBLE POWER SUPPLY EMITS A SUSTAINED 
ALARM TONE
 
The uninterruptible power sup-
ply has stopped sending power 
to connected equipment. 
The connected equipment exceeds the specified maximum load. 
Disconnect nonessential equipment from the uninterruptible power supply 
to eliminate the overload condition. 
Press the off button, then the on button to restore power to connected equip-
ment. 
FAULT LED LIT 
 
There is an internal uninterrup-
tible power supply fault. 
Do not attempt to use the uninterruptible power supply. Turn off the unit 
and have it serviced immediately. 
REPLACE BATTERY LED IS LIT
 
The replace battery LED 
flashes and a short beep is 
emitted every two seconds to 
indicate the battery is discon-
nected. 
Check that the battery connectors are fully engaged. 
The battery is weak. 
Allow the battery to recharge for 24 hours. Then, perform a self-test. If the 
problem persists after recharging, replace the battery. 
A battery self-test has failed. The 
uninterruptible 
power supply emits short beeps for one minute and the 
replace battery LED is lit. The uninterruptible power supply 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 battery passes the self-test. 
UNINTERRUPTIBLE POWER SUPPLY OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE 
EXISTS
 
There is very high, low, or 
distorted line voltage.  
Move the uninterruptible power supply to a different outlet on a different 
circuit. Inexpensive fuel powered generators might distort the voltage. Test 
the input voltage with the utility voltage display. See Operation.
