They also protect equipment against damaging surges and line noise. Battery Replacement Door: Under normal conditions, the original battery in the UPS will last several years. Battery replacement should be performed only by qualified service personnel. Refer to "Battery Warnings" in the Safety section. Should the UPS require battery replacement, visit Tripp Lite on the Web at www.tripplite.com/support/ battery/index.cfm to locate the specific replacement battery for the UPS. Power Sensitivity Adjustment: This dial is normally set fully counterclockwise, which enables the UPS to protect against waveform distortions in its AC input. When such distortions occur, the UPS will normally switch to providing PWM sinewave power from its battery reserves for as long as the distortions are present. In some areas with poor utility power or where the UPS's input power comes from a backup generator, frequent brownouts and/or chronic waveform distortion could cause the UPS to switch to battery too often, draining its battery reserves. It may be possible to reduce how often the UPS switches to battery due to waveform distortion or brownouts 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 and switches to battery less often. 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. The experiment should last long enough to assure that all expected line conditions are encountered. USB Communication Port: This port can connect your UPS to any computer for automatic file saves and unattended shutdown in the event of a power failure. Use with Tripp Lite's PowerAlert Software and appropriate USB cable. A PowerAlert CD and USB cable may be included with your UPS; if so, insert the CD into the CD tray of your computer and follow the installation instructions. If PowerAlert Software and the appropriate cable did not come with your UPS, you can obtain the software FREE via the Web at www.tripplite.com. Any user-supplied USB cable may then be used to connect your UPS to your computer. NOTE: This connection is optional. The UPS will work properly without this connection. 5
