American Power Conversion 8000 VA, 220 VAC Bypass mode. Refer to Troubleshooting in this manual

Feature	Function
Normal/Bypass	Manual bypass enables the user to manually put connected equipment into bypass
	mode. While in bypass mode the utility power bypasses the UPS and goes directly
	to the connected equipment. Battery operation is not available while the UPS is in
	bypass mode. Refer to Troubleshooting in this manual.
Cold Start	This is not a normal condition.
	When there is no utility power and the UPS is off, press and hold the		button
	to power up the UPS and connected equipment.
	The UPS will emit two beeps. During the second beep, release the button.
Self-Test	Automatic: The UPS performs a self-test automatically when turned on, and
	every two weeks thereafter, (by default). During the self-test, the UPS briefly
	operates the connected equipment on battery.
	Manual: Press and hold the	button for a few seconds to initiate the self-test.

Diagnostic Utility Voltage

The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS into the normal utility power.

The UPS starts a self-test as part of this procedure. The self-test does not affect the voltage display.

Press and hold the button to view the utility voltage bar graph display. After a few seconds the five-LED, Battery Charge

display on the right of the front panel shows the utility input voltage. Refer to the figure at left for the voltage reading (values are not listed on the UPS). The display indicates the voltage is between the displayed value on the list and the next higher value.

BATTERY OPERATION

The UPS switches to battery operation automatically if the utility power fails. While running on battery, an alarm beeps four times every 30 seconds.

Press the button to silence this alarm. If the utility power does not return, the UPS continues to supply power to the connected equipment until the battery is fully discharged.

When two minutes of run time remain the UPS emits a continuous beeping. If PowerChute software or the Network Management card are not being used, files must be manually saved and the computer must be turned off before the UPS fully discharges the battery.

The UPS battery life differs based on usage and environment. Refer to www.apc.com for on battery runtimes.
