201112103 93-2459.qxd 1/9/2012 12:21 PM Page 9 Basic Operation continued Other UPS Features (Rear Panel) Communications Ports (USB or RS-232): These ports connect your UPS to any workstation or server. Use with Tripp Lite's PowerAlert Software and included cables to enable your computer to automatically save open files and shut down equipment during a blackout. Also use PowerAlert Software to monitor a wide variety of AC line power and UPS operating conditions. Consult your PowerAlert Software manual or contact Tripp Lite Customer Support for more information. See "Optional Installation" section for installation instructions. Relay Contact Interface Port: This female DB9 port sends contact-closure signals to indicate line-fail and low battery status. See "Optional Installation" section for installation instructions. EPO (Emergency Power Off) Port (Select Models Only): Your UPS features a EPO port that may be used to connect the UPS to a contact closure switch to enable emergency inverter shutdown. See Optional Installation. Accessory Slot: Remove the small cover panel from this slot to install optional accessories to remotely monitor and control your UPS. Refer to your accessory's manual for installation instructions. Contact Tripp Lite Customer Support at (773) 869-1234 for more information, including a list of available SNMP, network management and connectivity products. Power Sensitivity Adjustment: This dial is normally set fully counter-clockwise, which enables the UPS to provide maximum protection against waveform distortions in its AC input. When such distortion occurs, the UPS will normally switch to providing sine wave power from its battery reserves for as long as the distortion is present. In areas with poor utility power or where the UPS's input power comes from a backup generator, chronic waveform distortion could cause the UPS to switch to battery too frequently, draining its battery reserves. You may be able to reduce how often your UPS switches to battery due to moderate waveform distortion by experimenting with different settings for this dial. As the dial is turned clockwise, the UPS becomes more tolerant of variations in its input power's AC waveform. NOTE: The further the dial is adjusted clockwise, the greater the degree of waveform distortion the UPS will allow to pass to connected equipment. When experimenting with different settings for this dial, operate connected equipment in a safe test mode so that the effect on the equipment of any waveform distortions in the UPS's output can be evaluated without disrupting critical operations. External Battery Connector (Select Models Only): Use to connect Tripp Lite external battery packs for additional runtime. Refer to instructions available with the battery pack for complete connection information and safety warnings. 9
