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.
