The UPS detects line voltage distortions (such as spikes, notches, dips, and swells) as well
as distortions caused by operation with inexpensive fuel-powered generators. By default, the
UPS reacts to distortions by transferring to on-battery operation to protect the connected
equipment. Where power quality is poor, the UPS may frequently transfer to on-battery
operation. If the connected equipment can operate normally under such conditions, reduce
the sensitivity setting to conserve battery capacity and service life.
To reduce UPS sensitivity, press the voltage sensitivity button
. Use a pointed object (such
as a pen) to do so. Press the button once to set sensitivity to medium. Press it again to set
sensitivity to low. Press the button a third time to reset to high sensitivity. You also can
change the sensitivity level through software.
Brightly lit: UPS is set to high sensitivity.
Dimly lit: UPS is set to medium sensitivity.
Off: UPS is set to low sensitivity.
Low Battery Warning Level
7 min Off: Low battery warning interval is about seven minutes
5 min Dimly lit: Low battery warning interval is about five minutes
2 min Brightly lit: Low battery warning interval is about two minutes
The low battery warning beeps to indicate low on- battery run time. It beeps periodically (ap-
proximately three times per minute) when less than seven minutes of run time remain. The
beeps are continuous when only two minutes of run time remain.
This may not be enough time to shut down some protected computer systems. To change
the warning interval default setting, press the
voltage sensitivity button while pressing and
holding the front-panel button.
