Input Cord: This permanently attached power cord connects your
UPS to a power outlet.
AC Receptacles (Varied by Model): These 15-, 20- and 30-amp
receptacles provide your connected equipment with pure sine-wave
AC output from the AC line during normal operation and from battery
power during blackouts and severe brownouts. Power provided at
these outlets is filtered to protect connected equipment against
damaging surges and line noise. The receptacles are divided into
numbered load banks, as labelled on the unit. Using PowerAlert
software and cabling, load banks one and two may be individually
turned off and on from a remote location, allowing users to reset or
reboot connected equipment.
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.
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.
Communications" in the "Optional Connections" section for
installation instructions.
Dry contact communications are simple, but some knowledge of
electronics is necessary to configure them. The DB9 port's pin
assignments are shown in the diagram. If the UPS battery is low, the
UPS sends a signal by bridging pins 1 and 5. If utility power fails, the
UPS sends a signal by bridging pins 8 and 5. To shut the UPS down
remotely, short pin 3~pin 9 for at least 3.8 seconds.
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.
