Basic Operation

Switches

System Enable Switch

This switch activates the battery charger and intelligent micro- processor. Always leave it in the “ON” (or “ENABLE/I”) position when your UPS is plugged in. Set the System Enable Switch to “OFF” (or “DISABLE/O”) only if you store or ship your UPS (to reduce battery drain).

Note: the “ ” light will flash until you engage the ON/Standby Switch to activate the “ON” mode (power ON at the UPS receptacles).

ON/Standby Switch

This momentary switch controls power to the UPS receptacles. Engage it momentarily and release it to toggle between the “ON” mode (power ON at the UPS receptacles) and “Standby” mode (power OFF at the UPS receptacles).

Mute/Test Switch

Use this momentary switch to do two things: Silence the UPS On Battery alarm

Engage this switch and release it to silence the UPS on Battery alarm, a series of short beeps that sounds intermittantly when the UPS is providing AC power from battery. Note: when the battery is nearly depleted, the Low Battery alarm, a continuous beep that cannot be silenced, will alert you to immediately shut down connected equipment.

Test your UPS’s battery charge

Leave your connected equipment ON. With your UPS plugged in and completely turned ON, engage this switch; hold it there for 5 seconds and release it. You will hear a series of short beeps as the UPS momentarily switches to battery to test its charge. The “” light will turn ON and the alarm (a long, continuous beep) will sound if your UPS fails a self-test and/or the UPS battery is less than fully charged. If this occurs, let the UPS charge for 12 hours and perform a second self-test. If the light continues to stay on, contact Tripp Lite for service. CAUTION: Do not unplug your UPS to test its batteries. This will remove safe electrical grounding and may introduce a damaging surge into your network connections.

Indicator Lights

Light descriptions apply when the UPS is plugged into a wall outlet and turned ON.

This green light will shine constantly to indicate AC power is available at the receptacles. It will flash to indicate AC power is not available. (See “System Enable Switch” and “On/Standby Switch” descriptions above.)

This multi-colored light displays 7 separate UPS battery charge conditions. It will turn from red (low) to yellow (medium) to green (full) to show you the level of battery charge. If the light is constant, your UPS is operating from line power, and the battery is charging. If the light is flashing, your UPS is operating from battery power, and the battery is discharging. When the light flashes red,
