Optional Installation

The following connections are optional. The UPS system will function properly without these connections.

1USB and Serial Communication Connection

Use the included USB cable 1a and/or RS-232 DB9 serial cable 1b to connect the communication port of a computer to the communication port of the UPS. Install the PowerAlert software appropriate for the computer’s operating system. Consult the PowerAlert manual for more information.

2EPO 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 UPS system’s output. Using the included cable 2a, connect the EPO port to a user-supplied normally closed or normally open switch. The pin assignment for the EPO port is shown in diagram 2b.

NOTE: The EPO port is not a phone line surge suppressor; do not connect a phone line to this port.

3External 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.

NOTE: Do not connect or disconnect battery packs when the UPS is running on battery power.

The illustration (see 3 ) 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.

The Battery Configuration Port automatically detects up to four external Tripp Lite battery packs and also estimates the remaining battery run time. Using the included RJ-45 cable 3a, connect the Battery Configuration port to a user-supplied Tripp Lite external battery pack.

NOTE: The Battery Configuration Port will only detect Tripp Lite external battery packs that support this feature. To determine whether a battery pack supports this feature, consult the battery pack owner’s manual. Do not connect to a network.

4Internal SNMP/WEB or Relay I/O 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. The accessory slot also supports an optional Tripp Lite programmable UPS management device (Model: RELAYIOCARD). This device that allows you to monitor UPS status and events and perform remote system shutdowns and battery tests.
