Basic Operation
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
NEMA 5-15R
two may be individually turned off and on from a remote location, allowing
users to reset or reboot connected equipment.
NEMA 5-15/20R
Other outlet types not
shown
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. Not
compatible with PoE (Power Over Ethernet) applications.
Communications
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 Installation.
