Accessory Slot
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. (Tripp Lite’s RELAYIOCARD is also available.) Visit www.tripplite.com/
support for more information, including a list of available SNMP, network management
and connectivity products.
Optional Connection
The following connections are optional. Your UPS system will function properly without these connections.
1
RS-232 Serial and USB Communication Connections
Use the included cable to connect the power module’s “RS-232” port to the
communication port on your computer. This will allow full network monitoring and
control of your UPS system. Install on your computer the Tripp Lite PowerAlert software
appropriate to your computer’s operating system. The UPS is also equipped with a
USB communication module.
An alternate contact closure module is available if necessary (Tripp Lite part #
RELAYIOMINI). By default, this module is disabled. To enable, move both DIP switches
to the USB position. Enabling this module disables the RS-232 port. The RS-232 port
is also disabled with the installation of an optional SNMP/Web card (Tripp Lite part #
SNMPWEBCARD). The SNMP/Web card can be used simultaneously with the USB
communication module.
2
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. Initiated in
normal operation (with AC power still present), the output will turn OFF and the LCD
will display “Emergency Shutoff.” In order to turn it back ON, remove the cable and
re-apply AC power.
The EPO port is not a phone line surge suppressor; do not connect a phone
line to this port.
3
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.
