Tripp Lite SU6000RT4U Optional Connection, USB and RS-232 Serial Communication Connection

Optional Connection

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

1USB and RS-232 Serial Communication Connection

Use the included USB cable 1a and/or RS-232 DB9 serial cable 1b 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 1c . 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.

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 output. Using the included cable 2a , connect the UPS's EPO port to a user-supplied normally open switch. The pin assignment for the EPO port is shown in diagram 2b . 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. The illustration shows the location of your UPS's External Battery Connector, where you will insert the battery pack cable 3a . 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 3b . 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 “EXTERNALBATTERIES”) without an external battery connected. There is a risk of damaging the UPS's internal battery system.

4Internal 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.
