TURNING THE UPS ON / OFF
To turn the UPS on: press and hold the On/Off button until the alarm sounds
one beep and then release. Then in approximately twenty seconds the UPS
will perform a five second self-test. Once the UPS has passed its self-test the
UPS will be ready for normal operation.
To turn the UPS off: press and hold the On/Off button until the alarm sounds
one beep and then release. The UPS will continue to charge the batteries
whenever it is plugged into a wall outlet and there is an acceptable AC voltage
present (95 - 140VAC).
ALARM SILENCER BUTTON
When the unit is operating in Battery mode, pressing the Alarm Silencer Button
will silence the audible alarm. Once the UPS reaches the LBW (Low Battery
Warning) threshold the alarm will start beeping. The alarm cannot be silenced
during the LBW alarm or any fault condition. Once the UPS transfers to the AC
mode the alarm will be reset to default.

ALARMS
BATTERY MODE
When the UPS is operating in the Battery mode, the AC normal LED will turn
off, the On-Battery LED will turn on and the alarm will sound one beep every
five seconds. Once the UPS returns to the normal AC mode, the alarm will
stop, the On-Battery LED will turn off and the AC normal LED will turn on.
LOW BATTERY WARNING
When the batteries reach the predetermined level, the Warning/Fault LED
will turn on and the alarm will sound two beeps every five seconds. The
audible alarm cannot be silenced during the LBW alarm. This information is
to inform the user that there is approximately two minutes of runtime
remaining before the UPS shuts down. This condition will continue until
either AC returns or the UPS’s self-protection circuit shuts the UPS down to
protect the battery from over discharging.
WEAK / BAD / DISCONNECTED BATTERY
The UPS automatically tests the battery’s condition. If the battery is weak,
bad, or disconnected, the Warning/Fault LED will turn on and the alarm will
sound three beeps every five minutes until the battery is either reconnected,
replaced or passes a self-test. The audible alarm cannot be silenced
during the Weak/Bad/Disconnected Battery alarm. It is recommended that
the UPS be allowed to charge overnight before performing a battery test to
confirm a Weak/Bad Battery condition.
OVERLOAD
When the amount of load attached to the UPS exceeds its power rating, the
Warning/Fault LED will turn on and the alarm will sound one beep every half
a second (AC and Battery modes). This alarm will remain on until the
excess load is removed, or the UPS’s self-protection circuit shuts the UPS
down. If the UPS has shutdown, remove part of the load and then press
the On/Off button to turn the UPS on. The audible alarm cannot be
silenced during the Overload alarm.
UPS FAULT
When the UPS detects an internal fault, the Warning/Fault LED will turn on
and the alarm will sound continuously, and the output will be turned off.
The audible alarm cannot be silenced during the Fault alarm. The fault
condition, in some instances, may be cleared by turning the UPS off and
then back on again. If the fault condition does not clear the UPS must be
sent in for service. See the Troubleshooting section.
