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. "Surge-Only" receptacles are used to
provide peripherals with surge protection without committing precious
battery power to support them during blackouts.
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 the 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 USB
cable. A USB cable is included with the UPS. PowerAlert Software is
available FREE via the Web at www.tripplite.com/software/. NOTE: This
connection is optional. The UPS will work properly without this
connection.
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.
Automatic Voltage Regulation: During brownouts, the UPS will
automatically correct low AC line voltage. When automatic voltage
regulation is operating, the UPS may click gently. This is a normal,
automatic operation of the UPS, and no action is required.
