Telephone or Telephone/Network Protection Jacks: These jacks
protect your equipment against surges over a telephone line or
telephone/network data line, depending on model. Connecting your
equipment to these jacks is optional. Your UPS will work properly
without this connection.
USB Port: The USB port connects your UPS to any USB workstation or
server. Using this port, your UPS can communicate line-fail and low-
battery status. Use with Tripp Lite software and any USB cable to
automatically save open files and shut down equipment during a
blackout. Contact Tripp Lite Customer Support or consult your power
protection software manual for more information.
Battery Replacement Door: Under normal conditions, the original
battery in your UPS will last several years. Battery replacement should
be performed only by qualified service personnel. Refer to "Battery
Warnings" in the Safety section. Should your 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 your UPS.
Power Sensitivity/Lowline Adjustment: This dial is normally set fully
counterclockwise, which enables the UPS to protect against waveform
distortions in its AC input. When such distortion occurs, the UPS will
normally switch to providing PWM sinewave power from its battery
reserves for as long as the distortion is 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. You may be able to reduce how often your 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 reduces the voltage point at which it switches to battery. NOTE: The
further the dial is adjusted clockwise, the greater the degree of
waveform distortion and the lower the input voltage 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
NORM DELAY
conditions are encountered.
External Battery Connector (Select Models Only): Use to connect a
single Tripp Lite external battery pack for additional runtime. The
specifications section of this manual lists the Tripp Lite external battery
pack that is compatible with select models. Refer to instructions
available with the battery pack for complete connection information and
safety warnings.
