Other UPS Features (Rear Panel)
AC Receptacles: Your UPS features 15-amp AC outlets. These output
receptacles provide your connected equipment with AC line power during
normal operation and battery power during blackouts and brownouts. The UPS
protects equipment connected to these receptacles against damaging surges
and line noise. If you have a serial or USB connection to your UPS, you can
remotely reboot connected equipment by turning the receptacles OFF and ON
NEMA 5-15R
using Tripp Lite's PowerAlert Software. Select models have their receptacles
divided into one or more load banks (labelled "LOAD 1," etc.) which may be
remotely switched OFF and ON using Tripp Lite UPS software without
interrupting power to equipment connected to the other outlets. 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. Select models also feature outlets labelled
"UNSWITCHED", which may not be remotely switched off. See software
instructions for details.
Communications Ports (USB or RS-232): These ports connect your UPS to
any workstation or server. Use with Tripp Lite's PowerAlert Software and
included cables to enable your computer to automatically save open files and
shut down equipment during a blackout. Also use PowerAlert Software to
monitor a wide variety of AC line power and UPS operating conditions. Consult
your PowerAlert Software manual or contact Tripp Lite Customer Support for
more information. See "USB and RS-232 Serial Communications" in the
"Optional Installation" section for installation instructions.
EPO (Emergency Power Off) Port: Your UPS features a EPO port that may be
used to connect the UPS to a contact closure switch to enable emergency
inverter shutdown. See Optional Installation.
Accessory Slot: Remove the small cover panel from this slot to install optional
accessories to remotely monitor and control your UPS. Refer to your
accessory's manual for installation instructions. Contact Tripp Lite Customer
Support at (773) 869-1234 for more information, including a list of available
SNMP , network management and connectivity products.
Power Sensitivity Adjustment: This dial is normally set fully counter-
clockwise, which enables the UPS to provide maximum protection against
waveform distortions in its AC input. When such distortion occurs, the UPS will
normally switch to providing 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 moderate 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.
