USB Port: The USB port connects your UPS to any USB workstation or server. Using this port, your UPS can communicate
DB9 Port (Select Models Only): The DB9 port connects your UPS to any workstation or server. Use with Tripp Lite’s PowerAlert UPS monitoring software and a DB9 cable to enable your computer to automatically save open files and shut down equipment during a blackout. The UPS can also report power availability and UPS status, and select UPS models have other capabilities. See PowerAlert manual.
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 on page 2.
External Battery Connector (Select Models Only): Use to connect battery pack(s) 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.
Input Breaker: Prevents high input current from damaging the UPS or the attached load. If this breaker trips, make sure your UPS is connected to nominal 120V AC power before resetting the circuit breaker by pushing the breaker switch in to reset.
Charge Level Switch: This switch should be set to the left unless you have connected multiple external batteries, in which case you may set it to EXTERNAL BATTERY, increasing your charger’s output so the additional batteries recharge faster.
Power Sensitivity Adjustment: This dial is normally set fully counter- clockwise, 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. 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 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.
