Basic Operation (Continued)

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 remaining in both internal and connected batteries. 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, close any files you are working on and shut down your computer.

Whenever your UPS is automatically correcting high or low AC line voltage, this green light will turn ON and the UPS will gently click. These are both normal, automatic operations of your UPS, and no action is required on your part.

This red light will turn ON if your UPS fails a self-test and/or the UPS battery is less than fully charged. If it lights, let the UPS charge for 12 hours, then perform a self-test. If the light continues to stay on, contact Tripp Lite for service.

This multi-colored light displays 4 separate UPS load conditions. It will turn from green (low) to yellow (medium) to red (high) as you connect equipment to show you the load level your UPS is supporting. When the light is red, your UPS is supporting a load above 85% of its capacity. If the red light begins flashing, then your UPS is severely overloaded. Remove overload immediately until light stops flashing.

This red light will turn ON when you set the Maintenance Bypass Switch to “BYPASS”, indicating that the Power Module has turned off its battery charger, allowing you to properly disconnect and replace the Battery Packs. The light may also come on if Battery Packs are improperly disconnected, indicating that the Power Module is protecting itself from potential overvoltages. While this light is on, the UPS will still provide filtered utility AC power and will provide battery backup power if any batteries are connected. DB9 communications are unaffected. To return the UPS's charger to normal operation, set the Maintenance Bypass Switch to “NORMAL”. If the light has come on due to improper battery disconnection, cycle the Maintenance Bypass Switch to “BY- PASS” then to “NORMAL” to reset the UPS.
