Basic Operation

Buttons (Front Panel)

Use the POWER button to switch your UPS between its four modes of operation.

OFF: No indicator lights are on. The UPS is completely shut down for storage or shipping. If the UPS is connected to AC power, it will start up in STANDBY mode. If the UPS is not connected to AC power and the POWER button is pressed for two seconds, the UPS will “cold start” into INVERT mode.

STANDBY: The “ ” light is flashing. The UPS is receiving AC power and using it to charge its internal batteries, but its outlets are not active. Pressing the POWER button while the UPS is in STANDBY will put the UPS in the ON mode. Unplugging the UPS or cutting AC power while the UPS is in STAND- BY will put the UPS in the OFF mode.

ON: The “” light is on. The UPS is receiving AC power, charging its batteries and delivering power to connected equipment. Pressing the POWER button while the UPS is ON will put the UPS in STANDBY mode. If AC power is lost while the UPS is ON (i.e. a blackout occurs), the UPS will switch into INVERT mode.

INVERT: The “ + – ” light is flashing. The UPS is powering connected equip- ment from battery backup. If AC power is restored, the UPS will switch to the ON mode. Pressing the POWER button while the UPS is in INVERT will put the UPS into the OFF mode. If the UPS is in INVERT and its batteries are drained, the UPS will switch to the OFF mode until AC power is restored, then switch to the ON mode.

Use the MUTE/TEST button to do two things:

SILENCE ALARM: Your UPS has three alarms. The first, the INVERT alarm,

emits four short beeps every ten seconds when the UPS is in INVERT mode,

to warn you that AC power has failed. The second, the OVERLOAD alarm,

emits short, rapid beeps when the UPS is in INVERT mode if the total power draw

of connected equipment exceeds the UPS’s output capacity, to warn you to

reduce the load. The third, the LOW BATTERY alarm, emits a constant beep

when the UPS is in INVERT mode and its batteries are very nearly depleted, to warn

you that connected equipment must shut down. To silence the INVERT or

OVERLOAD alarms, press the MUTE/TEST button. The LOW BATTERY

alarm will only stop when the UPS switches to the OFF or ON mode.

SELF-TEST BATTERIES AND ALARMS: If your UPS is in the ON mode and has a load connected, you may test its batteries by pressing the MUTE/TEST button for two seconds. The UPS will switch to INVERT mode for several seconds. Normally, the INVERT alarm (four short beeps) will sound, indicating that the system is working properly. If the OVERLOAD alarm (short, rapid beeps) sounds, reduce the load on the UPS. If the LOW BATTERY alarm (a constant beep) sounds, your UPS’s batteries may need replacing or they may simply be less than fully charged. Let the UPS charge for 12 hours, then perform a second self-test. If the LOW BATTERY alarm sounds again, contact Tripp Lite for service. Do not unplug your UPS to test its batteries, or you will remove safe electrical grounding and may introduce a damaging surge into your network connections.
