Basic Operation
Other UPS Features
AC Receptacles: The receptacles provide your connected equipment with AC
line power during normal operation and battery power during blackouts and
brownouts. They also protect your equipment against damaging surges and line
noise.
USB or DB9 Communication Port: These ports 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 or
DB9 cable. You can obtain the software FREE via the Web at www.tripplite.com.
Any user-supplied DB9 pass-through or USB cable may be used to connect your
UPS to your computer.
Note: This connection is optional. The UPS will work properly without this connection.
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 www.tripplite.com/products/
battery-finder to locate the specific replacement battery for your UPS.
Input Breakers: Protects your electrical circuit from overcurrent draw from the
UPS load. If breaker trips, remove some of the load, then reset it by pressing the
breaker in.
Equipotential Connection: Use this to connect any equipment that requires a
chassis ground.
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 distortion occurs, the UPS will normally switch to providing PWM
sine wave power from its battery reserves for as long as the distortion is present.
In areas with poor utility power or where the UPS’s input power comes from a
backup generator, chronic waveform distortion could cause the UPS to switch
to battery too frequently, draining its battery reserves. You may be able to
reduce how often your UPS switches to battery due to waveform distortion 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.
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.
