Basic Operation (continued)

Front Panel Indicator Lights continued

“REPLACE BATT” LED: This red light will illuminate constantly and the UPS alarm will beep every 2 seconds if your UPS’s microprocessor detects a battery fault or if your UPS fails the automatic self-test (after you turn your UPS ON) and the UPS battery is less than fully charged. Let the UPS system charge for at least 12 hours and perform a self test using the “ON/TEST Button” as described on page 7. If the light continues to stay on, contact Tripp Lite for service.

Rear Panel

Accessory Slot: Remove the small cover panel from this slot to use optional accessories to remotely monitor and control your UPS. Contact Tripp Lite Customer Support at (773) 869-1234 for more information, including a list of available SNMP, network management and connectivity products.

External Battery Pack Connector (configuration varies by model): Use to connect optional Tripp Lite Battery Packs for additional runtime. Contact Tripp Lite Customer Support at (773) 869-1234 for the appropriate Tripp Lite battery pack to connect. Refer to instructions available with the Battery Pack for complete connection information and safety warnings.

Fan: The fan cools the UPS’s internal components. It is always on when line power is present.

Input Circuit Breaker Switch: This resettable breaker prevents high input current from damaging the UPS or the attached load. If this breaker trips, make sure your UPS is connected to AC power of the proper voltage before resetting the circuit breaker by pushing the breaker switch in.

Ground Screw: Use this to connect any equipment that requires a chassis ground.

Output Circuit Breakers Switches (Select Models Only): These resettable circuit breakers protect your UPS from output overload. If one or both breakers trip, remove some of the load on the circuit(s) and allow the UPS to cool before pressing the breaker switch(es) in to reset.
