5. Operation
"BATT LOW" LED: This yellow LED will illuminate when the UPS system's
battery charge level is low. The UPS alarm will beep until the batteries are
either depleted or adequately recharged.
"ON BATT" LED: This green LED will illuminate continuously to indicate AC
line voltage is absent (or out of range) and the UPS system is providing
equipment with battery-derived AC power. The UPS system will also beep
every 2 seconds (unless silenced by the "ON/TEST" button) and the % level
LEDs (25%, 50%, 75%, 100%) will display the battery charge level.
"REPLACE BATT" LED: This red LED as well as the red "FAULT" LED will
illuminate continuously and the UPS alarm will beep every 2 seconds if the
UPS system fails the automatic self-test. Allow the UPS system to charge
for at least 12 hours and perform a self-test as described in Section 5.1:
Front Panel Switches. If the condition persists, contact Tripp Lite.
