Basic Operation continued Telephone or Telephone/Network Protection Jacks: These jacks protect your equipment against surges over a telephone line or telephone/network data line, depending on model. Connecting your equipment to these jacks is optional. Your UPS will work properly without this connection. USB Port: The USB port connects your UPS to any USB workstation or server. Using this port, your UPS can communicate line-fail and lowbattery status. Use with Tripp Lite software and any USB cable to automatically save open files and shut down equipment during a blackout. Contact Tripp Lite Customer Support or consult your power protection software manual for more information. Battery Replacement Door: Under normal conditions, the original battery in your UPS will last several years. Battery replacement should be performed only by qualified service personnel. Refer to "Battery Warnings" in the Safety section. Should your 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 your UPS. Power Sensitivity/Lowline Adjustment: This dial is normally set fully counterclockwise, which enables the UPS to protect against waveform distortions in its AC input. When such distortion occurs, the UPS will normally switch to providing PWM sinewave power from its battery reserves for as long as the distortion is 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. You may be able to reduce how often your 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 reduces the voltage point at which it switches to battery. NOTE: The further the dial is adjusted clockwise, the greater the degree of waveform distortion and the lower the input voltage 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 NORM cDELoAY nditions are encountered. External Battery Connector (Select Models Only): Use to connect a single Tripp Lite external battery pack for additional runtime. The specifications section of this manual lists the Tripp Lite external battery pack that is compatible with select models. Refer to instructions available with the battery pack for complete connection information and safety warnings. 7 200912037 93-2248.indd 7 12/17/2009 11:06:02 AM
