American Power Conversion 7500/10000 VA On Battery Operation, Affect the voltage display

Feature	Function
Normal /Bypass	Manually switch connected equipment to bypass mode, so that utility power is
	sent directly to connected equipment. Battery operation is not available while
	the UPS is in bypass mode. (See Troubleshooting.)
Cold Start	This is not a normal condition.
	Supply immediate battery power to the UPS and connected equipment (see
	Troubleshooting). 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.

	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	The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS
Voltage	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.

On 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 runtime remain the UPS emits a continuous beep. If PowerChute or the Web/SNMP card is not being used, files must be manually saved and the computer must be properly shut down before the UPS fully discharges the battery.

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