Front Panel Indicator Lights 

continued

“BYPASS” LED:

This yellow light will flash to indicate that the

UPS’s DC/AC inverter is deactivated and the UPS is in the “Bypass”
mode. During normal operation this LED will light briefly when the
unit is plugged in, but if an internal fault or overload occurs this light
will flash constantly to show that connected equipment will receive
filtered AC mains power, but will not receive battery power during a
blackout. In this case, contact Tripp Lite for service.

“FAULT” LED (select models only):

This red light will flash when

your UPS detects an internal fault (overheating, overvoltages, etc.) or
when it detects a wiring fault in your wall outlet (reversed phases,
missing ground, etc.)  The UPS will only detect wiring faults when it
is plugged into a utility outlet but not turned ON. If the light persists
after restarting the UPS, contact an electrician to check the AC line.
Your UPS will identify the presence of most (but not all) wiring faults.

“LOAD ACTIVE METER” LED:

This green light will illuminate

when your UPS is receiving AC power to indicate that the set of four
dual-function LEDs is displaying the load level of your UPS.

“BATT ACTIVE METER” LED:

This green light will illuminate

when your UPS is operating from battery power to indicate that the
set of four dual-function LEDs is displaying the battery charge level
of your UPS. Note: the “ON BATT” LED will also be illuminated. 

“OVERLOAD” LED:

This red light will illuminate constantly to indicate

that your UPS’s capacity has been exceeded while it is in on-line operation.
The UPS alarm will beep continuously. Immediately remove overload
until light and alarm goes off. If you do not immediately remove the
overload, the UPS will transfer from on-line to bypass operation.

“BATT LOW” LED:

This yellow light will illuminate when your UPS’s

battery charge level is low. The UPS alarm will beep until either the
battery charge is depleted or the batteries are adequately recharged.

“ON BATT” LED:

This green light will illuminate constantly to

indicate that AC line voltage is not present and your UPS is providing
your equipment with battery power. The UPS will also beep every two
seconds, unless silenced by the “ON/TEST” Button. When this light
is illuminated, you can monitor the battery charge level of your UPS
on the “BATT ACTIVE METER” LEDs.
