1.Place the UPS to avoid:

∙Direct sunlight

∙Excessive heat

∙Excessive humidity or contact with liquids

The UPS can be wall mounted (optional) see mounting instructions on back.

2.Plug the UPS directly into the power outlet; not into a surge protector or generator.

Socket Location: back side

APC Back-UPS Office protects modem, fax, or phone from surges when it is connected through the UPS as shown in the adjacent drawing.

Note: Telephone line surge protection can be rendered inoperable if connections are not made as shown.

Three - Battery Power Supplied Outlets (solid lines) Data sensitive equipment such as a computer, monitor, and external drives are connected to these outlets. When the UPS is switched “On,” conditioned utility power is supplied. Battery power is automatically provided in case of utility failure. No power (utility or battery) is supplied to these outlets when the UPS is switched “Off.”

Three - Surge Only Protected Outlets (dashed lines) Devices like a printer, fax machine, scanner, or even a desk lamp should be powered by these outlets. These outlets do not provide power during a power outage. These three outlets are powered

whenever utility power is available and the UPS is switched “On.”

Self-Test

A UPS Self -Test is performed whenever the unit is switched on and every two weeks of operation. Details about Self-Test can be found in the Self- Test section.

Battery charging

∙The battery charges whenever the UPS is connected to utility power and is switched “On .”

∙UPS runtime is reduced until the battery is

fully charged (approximately four hours). Keep the UPS “plugged in” and switched “On” to maximize available runtime.

The visual and audible UPS status indicators are described below:

Replace Battery (red) - This indicator

lights when a UPS Self -Test has determined the battery is weakened by frequent outages or is near the end of its useful life. Leave the UPS “On” overnight to recharge, then repeat the Self -Test. If the Replace Battery indicator is still lit, the battery should be replaced within two weeks (see Battery Replacement). Failure to promptly replace the battery risks the possibility of premature shut-down during a power outage.

Chirps for 1 Minute Every 5 Hours - This alarm indicates the battery has

failed the Self-Test.

On Battery (yellow) - This indicator

lights when utility power is unavailable or outside safe limits. The UPS battery is powering the Battery Power Supplied outlets.

Four Beeps Every 30 Seconds - This alarm indicates Battery Power Supplied

outlets are now battery powered. The alarm ceases when the UPS returns to “On Line” operation.

Continuous Beeping - This alarm indicates a Low Battery condition is

reached. Battery runtime is very low. Immediately, perform the UPS Shutdown Procedure.

Building Wiring Fault (red) - If the

building wiring fault indicator is lit, one of the following conditions exists:

∙Open or high resistance ground

∙Hot and neutral polarity reversal

∙Overloaded neutral circuit

Improper building wiring will not prevent the UPS from operating but will limit its protection capability. Faulty building wiring could result in equipment damage that is not covered by APC. Please refer to APC's Equipment Protection Policy for details.

On Line (green) - This indicator is lit whenever the UPS is switched “On” and it is supplying conditioned utility power to the outlets. This indicator is unlit for approximately four seconds during the Self -Test.

Overload Audible Indicators

Continuous Beeps for 30 Seconds - This alarm indicates the UPS has

detected an overload after Self-Test.

Continuous Two-tone Beep - This alarm indicates a severe overload is detected while operating on-battery. The UPS

will emit this sound until the UPS shuts down.

When the On Battery indicator is lit, follow this procedure to shutdown the computer, UPS, and any equipment connected to the Battery Power Supplied Outlets.

1.Save the files you are working on.

2.Exit all applications cleanly.

3.Perform an orderly shut down of the operating system.

4.Switch “Off” all equipment connected to the UPS.

5.Switch “Off” the UPS to maintain battery capacity.

Note: The procedure above needs to be completed before the battery is fully discharged. Loss of data or corruption of the operating system is possible if this procedure is not completed before the battery is fully discharged.

A Self-Test can be started at any time by switching the UPS “Off” and then “On.” A Self - Test is performed automatically every two weeks of continuous operation.

∙Perform the UPS Shutdown Procedure before switching the UPS “Off .”

∙A Self-Test should be performed with all connected devices switched “On,” whenever a device is first connected to a Battery Power Supplied Outlet.
