201112101 93-2190.qxd 12/29/2011 4:21 PM Page 7 Basic Operation continued Other UPS Features USB port RS-232 (DB9 port) AC Receptacles: These output receptacles provide your connected equipment with AC line power during normal operation and battery power during power outages. The UPS protects equipment connected to these receptacles against damaging surges and line noise. If you have a USB or DB9 connection to your UPS, you can remotely reboot connected equipment by turning its receptacles OFF and ON using Tripp Lite software. Select models have a receptacle or receptacles (clearly identified on the rear panel) that may be remotely switched ON and OFF without interrupting power to other outlets. See software instructions for details. Communication Ports (USB or RS-232) (Select Models Only): 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 "USB Communications" and "RS-232 Serial Communications" in the "Optional Installation" section for installation instructions. Battery Replacement Door: Under normal conditions, the original battery in your UPS will last several years. Refer to "Battery Warnings" in the Safety section on page 2. Input Breaker: Protects your electrical circuit from overcurrent draw from the UPS load. If this breaker trips, remove some of the load, then reset it by pressing the breaker in. NORM DELAY External Battery Connector (Select Models Only): Use to connect one or more Tripp Lite battery packs for additional runtime. Refer to Specifications and/or the label next to the connector to determine the appropriate variety of battery pack to use. Refer to the battery pack instruction manual for complete installation information and important safety warnings. See "External Battery Connection" in the "Optional Installation" section. Battery Charge Level Switch (Select Models Only): Select models feature a switch that controls the UPS system's battery charge rate. If you connect more than one external battery, set the Battery Charge Level Switch to the right. 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 without an external battery connected. There is a risk of damaging the UPS's internal battery system. Power Sensitivity Adjustment (Select Models Only): 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 sine wave power from its battery reserves for as long as the distortion is present. 7
