Indicator Lights

All Indicator Light descriptions apply when the UPS is plugged into an AC outlet and turned on.

LINE POWER: This green light will turn ON whenever your UPS is receiving normal AC line power. It will flash while the UPS is in CHARGE ONLY mode to indicate that the UPS will not provide battery backup during a black- out or brownout.

BATTERY POWER: This yellow light will turn ON when your UPS is pro- viding your equipment with battery power.

BATTERY CHARGE: This red light will turn ON continuously after the UPS runs a self-test to indicate that the UPS’s battery is weakly charged. If it remains lit after you have allowed the UPS to charge for twelve hours and have run a second self-test, contact Tripp Lite for service.

OVERLOAD (Select models only): This red light will turn ON continuously when the UPS is providing power from battery or after the UPS runs a self-test to indicate that the UPS’s inverter is overloaded. If it lights up, immediately remove some of the equipment connected to the UPS and run a self-test. Large overloads may cause your UPS to shut down.

VOLTAGE REGULATION (Select models only): This light will turn ON when your UPS is automatically correcting high or low utility line voltage. The UPS will also click gently when this automatic voltage regu- lation is operating. These are both normal functions of your UPS, and no action is required on your part.

Other UPS Features

AC Receptacles: “UPS/Surge” receptacles are used to provide your con- nected equipment with AC line power during normal operation and bat- tery power during blackouts and brownouts. They also protect your equip- ment against damaging surges and line noise. “Surge-only” receptacles (identified on the back of select UPS models) are used to provide periph- erals with surge protection without committing precious battery power to support them during blackouts.
