Optional Connection
The following connections are optional. Your UPS system will function properly without
these connections.
USB and RS-232 Serial Communication Connection
Use the included USB cable and/or RS-232 DB9 serial cable to connect the
communication port of your computer to the communication port of your UPS. Install on
your computer the Tripp Lite PowerAlert Software appropriate to your computer's
operating system. Consult your PowerAlert manual for more information.
Dry Contact Note: Dry contact communications are simple, but some knowledge of
electronics is necessary to configure them. The DB9 port's pin assignments are shown in
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 and pin 9 for at least 3.8 seconds.
EPO Port Connection
This optional feature is only for those applications that require connection to a facility's
Emergency Power Off (EPO) circuit. When the power module is connected to this circuit,
it enables emergency shutdown of the output. Using the included cable , connect the
UPS's EPO port to a user-supplied normally open switch. The pin assignment for the EPO
port is shown in diagram . The EPO port is not a phone line surge suppressor; do
not connect a phone line to this port.

External Battery Connection
Your UPS comes with a robust internal battery system; external batteries are needed only
to extend runtime. Adding external batteries will increase recharge time as well as
runtime. The illustration shows the location of your UPS's External Battery Connector,
where you will insert the battery pack cable . Complete installation instructions for
your battery pack appear in the battery pack owner's manual. Make sure that cables are
fully inserted into their connectors. Small sparks may result during battery connection;
this is normal. Do not connect or disconnect battery packs when the UPS is running on
battery power.
NOTE: Select models feature a Battery Charge Level Switch . If you connect any
external batteries to these models, set the Battery Charge Level Switch (see
diagram) to the right (labeled “EXTERNAL BATTERIES”). This will increase your
UPS's charger output so the additional batteries charge faster.
CAUTION! DO NOT set the Battery Charge Level Switch to the right (labeled
“EXTERNAL BATTERIES”) without an external battery connected. There is a risk
of damaging the UPS's internal battery system.
Internal SNMP/WEB Card Insertion
Remove the slot's cover to install an optional internal SNMP/Web accessory card (Model:
SNMPWEBCARD) to enable remote UPS monitoring and control via SNMP, Web or
telnet. Contact Tripp Lite Customer Support at (773) 869-1234 for more information,
including a list of available SNMP, network management and connectivity products.
