Switch
1. Main Power Switch
This switch activates three separate UPS functions:
UPS Power
Press the switch,
hold it for 3 seconds
and release it to turn the UPS
ON or OFF.*
Alarm Silence
Press the switch and
immediately release it
to silence the UPS Alarm.
UPS Cold Start
Press the switch,
hold it for 5 seconds
and release it to turn your UPS
ON and to use it as a stand-alone power source (operating from the
battery without AC input).**
* The UPS will execute a 10-second self-test when you turn it on. The “Normal" LED will illuminate, and the UPS will beep once
to indicate the UPS is turned ON. If the UPS alarm sounds and the "Replace Battery" LED illuminates, turn your UPS OFF, let
your UPS charge its batteries for 12 hours and turn UPS back ON to repeat the automatic self-test. If alarm still sounds, contact
Tripp Lite for service. CAUTION: Do not unplug your UPS to test its batteries. This will remove safe electrical grounding and may
introduce a damaging surge into your network connections.
** The "Backup" LED will illuminate since your UPS will operate from battery power.
