Basic Operation
AC Receptacles (Varies by Model): These 15-, 20- or 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 by 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
NEMA 5-15R
one and 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 for configuration. 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 remotely shut down the UPS, 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 for more
information.
