3.0 OPERATION
NOTE:
In order to
operate
the UPS, you must first plug the battery
enable
plug(s) into
the battery enable socket(s) behind the front panel of the UPS.
On/Off Button
The On/Off button is a dual function control:
• When the UPS is off and AC power is present to the UPS input, pressing the On/Off
button for more than 2 seconds will turn the UPS output on.
• If battery is connected, pressing the On/Off switch for 2 seconds or more will “cold-
start” the UPS on its internal battery with no incoming AC present.
• When the UPS is on, pressing the On/Off button for more than 2 seconds will
turn off the UPS output power.
Test/Silence Button
The Test/Silence button is a dual function control:
• Pressing the Test/Silence button when AC power is present and the
UPS is operating causes the UPS to enter a self-test mode in which
it tests both battery and inverter for a few seconds before returning to the AC supply.
We
recommend
you close all open files before initiating self-test.
• When AC power fails, the UPS warns you with an audible alarm. The Test/Silence
button is used to silence the alarm. When battery power begins to run low, the audible
alarm will automatically return and beep at a faster rate.
