Input Cord Connection: This IEC320-C20 or IEC320-C14 inlet
enables the UPS to be connected to an AC power source via a
user-supplied cord with country-specific plug. See "Connection and
Start-Up".
AC Receptacles (Varied by Model): These 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. Select
models feature receptacles arranged in numbered load banks, as labelled
on the unit. Using PowerAlert software and cabling, load banks can be
individually turned off and on from a remote location, allowing users to
reset or reboot connected equipment.
Telephone/Network Protection Jacks: These jacks protect your
equipment against surges over a telephone line or telephone/network
data line. Connecting your equipment to these jacks is optional. Your
UPS will work properly without this connection.
(Power Over Ethernet) applications.
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 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 Connections."
