HP UPS R1500 GENERATION 2 manual Initiating a self-test, Silencing an audible alarm, Battery mode

Page 24

Battery mode

In Battery mode, the UPS supplies power without being connected to utility power.

To power up the UPS without using utility power, press and hold the Power On/Standby button ("UPS front panel controls" on page 7) for two seconds.

Initiating a self-test

To initiate a self-test, press and hold the Test/Alarm Reset button ("UPS front panel controls" on page 7) for three seconds.

Because a portion of the self-test requires battery power, the self-test cannot be initiated if the batteries are less than 90 percent charged. If the UPS detects a problem, the appropriate LED ("UPS front panel LED indicators" on page 8) illuminates and an audible alarm may sound.

For information on what to do if the self-test detects a problem, see "Troubleshooting (on page 33)."

Silencing an audible alarm

To silence an alarm, press the Test/Alarm Reset button ("UPS front panel controls" on page 7).

IMPORTANT:

•Although the audible alarm silences, the condition that caused the alarm to sound may still exist.

•If a utility power failure caused the alarm (the Utility LED or the General Alarm LED illuminates red), the alarm silences after power is restored.

For information about audible alarm conditions, see "LED and audible alarm troubleshooting (on page 33)."

Powering down the UPS

1.Shut down all connected load devices.

2.Press the Power On/Standby button. Power to the output receptacles ceases.

3.Disconnect the UPS from utility power.

4.Wait at least 60 seconds for the UPS internal circuitry to discharge.
