Basic Operation
Other UPS Features
AC Receptacles: "UPS/Surge" receptacles are used to provide
connected equipment with AC line power during normal operation
and battery power during blackouts and brownouts. They also protect
equipment against damaging surges and line noise. Select models
feature special outlets (clearly labeled on the rear panel), which
provide surge-only (not battery backup) protection designed for laser
printers and other heavy-draw devices.
Telephone/DSL/Ethernet Protection Jacks: These jacks protect
equipment against surges over a telephone or data line. Connecting
equipment to these jacks is optional. The UPS will work properly
without this connection.
USB Communication Port: This port can connect your UPS to any
computer for automatic file saves and unattended shutdown in the
event of a power failure. Use with Tripp Lite's PowerAlert Software
(available as a FREE download at www.tripplite.com) and appropriate
USB cable. A USB cable may be included with your UPS. If the
appropriate cable did not come with your UPS, any user-supplied
USB cable may then be used to connect your UPS to your computer.
This connection is optional. The UPS will work properly without this
connection. Note: This UPS System provides basic communication
compatibility with most integrated Windows , Macintosh and Linux
® ® ®
power management applications.
Battery Replacement Door: Under normal conditions, the original
battery in the UPS will last several years. Battery replacement should be
performed only by qualified service personnel. Refer to "Battery
Warnings" in the Safety section. Should the UPS require battery
replacement, visit Tripp Lite on the Web at www.tripplite.com/support/
battery/index.cfm to locate the specific replacement battery for the UPS.
Power Sensitivity Adjustment: This dial is normally set fully
counterclockwise, which enables the UPS to protect against
waveform distortions in its AC input. When such distortions occur, the
UPS will normally switch to providing PWM sinewave power from its
battery reserves for as long as the distortions are present. In some
areas with poor utility power or where the UPS's input power comes
from a backup generator, frequent brownouts and/or chronic
waveform distortion could cause the UPS to switch to battery too
often, draining its battery reserves. It may be possible to reduce how
often the UPS switches to battery due to waveform distortion or
brownouts by experimenting with different settings for this dial. As
the dial is turned clockwise, the UPS becomes more tolerant of
variations in its input power's AC waveform and switches to battery
less often. NOTE: The further the dial is adjusted clockwise, the
greater the degree of waveform distortion the UPS will allow to pass
to connected equipment. When experimenting with different settings
for this dial, operate connected equipment in a safe test mode so
that the effect on the equipment of any waveform distortions in the
UPS's output can be evaluated without disrupting critical operations.
The experiment should last long enough to assure that all expected
line conditions are encountered.
