Switch

1. Main Power Switch

This switch activates three separate UPS functions:

UPS Power

Press the switch, hold it for 3 seconds until you hear a beep then release it during the beep to turn the UPS ON or OFF.*

Alarm Silence

When the on battery alarm is sounding, press this switch and immediately release it to silence the UPS Alarm.

UPS Cold Start

In the absence of AC input, press this switch, hold it for 3 seconds and then 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 at 1 (773) 869-1234. 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.
