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.
Phone/Network Line Surge Suppression Jacks: If your UPS is equipped
with these jacks, they will protect connected equipment against surges over a
phone or network line. Connecting your equipment to these jacks is optional;
your UPS will work properly without this connection. For connection
instructions, see “Optional Connections” in the Installation section.
Not compatible with PoE (Power Over Ethernet) applications.
USB or DB9 Communication Port (select models only): These ports can
connect your UPS to any computer for automatic file saves and unattended
shutdown in the event of a power failure. Use with Tripp Lite’s PowerAlert
Software and appropriate USB or DB9 cable. A PowerAlert CD and USB or
DB9 cable may be included with your UPS; if so, insert the CD into the CD
tray of your computer and follow the installation instructions. If PowerAlert
Software and the appropriate cable did not come with your UPS, you can
obtain the software FREE via the Web at www.tripplite.com. Any user-
supplied DB9 pass-through or USB cable may then be used to connect your
UPS to your computer. NOTE: This connection is optional. The UPS will work
properly without this connection.
The DB9 port can be used to monitor and control your UPS using either RS-
232 or dry contact protocols.
RS-232 communications are complex but easy to implement by using a DB9
cable to connect the UPS to a computer with Tripp Lite PowerAlert Software
installed.
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 at the left.
Units with both USB and DB9 ports: 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.
Units with DB9 ports only: 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, send a 5V to 12V signal
on pin 3 (using pin 5 as the negative ground) for at least 3.8 seconds.
EPO (Emergency Power Off) Port: Select models feature a EPO port that
may be used to connect the UPS to a contact closure switch to enable
emergency inverter shutdown. See Optional Installation.
