“BYPASS” LED:
This yellow light will illuminate 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 occurs this light will illumi-
nate 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.) If the light persists after restarting the UPS, con-
tact 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 indi-
cate 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 immedi-
ately 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 sec-
onds, unless silenced by the “ON/TEST” Switch. When this light is
illuminated, you can monitor the battery charge level of your UPS on
the “BATT ACTIVE METER” LEDs.
“REPLACE BATT” LED:
This red light will illuminate constantly and
the UPS alarm will sound three beeps* if your UPS’s microprocessor
detects a battery fault or if your UPS fails the automatic self-test (after
you turn your UPS ON) and the UPS battery is less than fully charged.
Turn the UPS OFF and let it charge for 12 hours and turn it back ON
to perform a second self test. If the light continues to stay on, contact
Tripp Lite for service.
*After the initial alarm, the UPS will beep once every hour until the problem is corrected.
