Basic Operation
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 and appropriate USB
cable. A PowerAlert CD and USB cable may be
included with your UPS; if so, insert the CD into
the CD tray of your computer and follow the instal-
lation instructions. If PowerAlert Software and a
USB cable did not come with your UPS, you can
obtain the software FREE via the Web at www.trip-
plite.com. Any user-supplied USB cable may then
be used to connect your UPS to your computer.
NOTE: This connection is optional. The UPS will
work properly without this connection.
