Inspection

Inspect the APC PowerStack 250/450 Uninterruptible Power Supply (UPS) upon receipt. Notify the carrier and dealer if there is damage. The packaging is recyclable; save it for reuse or dispose of it properly.

Battery Connection

Before beginning installation of the UPS, please follow the Battery Connection instructions on the front of the unit, or follow the steps under Replacing the Battery Pack.

Placement

Warning! Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the warranty.

Rack Mounting

The UPS comes with standard 19" (46.5 cm) rack mount brackets. It is supplied with four (4) screws to attach the mounting brackets (ears) to the chassis.

Select a rack location with adequate air flow that is free from excessive dust. Ensure that the air vents on the sides of the UPS are not blocked. Do not operate the UPS where temperature or humidity are outside the limits in the Specifications section of this manual.

Wall Mounting

The brackets on the UPS can be rotated 90 ° for wall mounting. Remove the screws, rotate the brackets, and insert the screws in the appropriate holes.

Wall-mountthe unit with the controls towards or at the top, not at the bottom of the unit .

Desktop Use

This UPS is provided with four adhesive-backedrubber “feet” for desktop use. Attach the feet to the bottom of the unit and remove the ears to use it on a desktop.

The recommended placement of the feet is shown by a small + on the bottom corners of the unit:

Check the Site Wiring Fault Indicator

Caution! If the site wiring fault indicator lights, get a qualified electrician to correct the building wiring.

Computer Interface Port

The interface port is used for communicating with the UPS. See enclosed documentation for details.

Connect the Battery Pack

The UPS is shipped with the battery pack disconnected. To connect the battery pack, follow the procedure in Replacing the Battery Pack, below.

Charge the battery pack

The UPS charges its battery pack whenever it is connected to utility power. The battery pack will charge fully during the first 4 hours of normal operation. Do not expect full battery back-upruntime during this initial charge period.

Operating Instructions

Switch On — Switch Off

On Battery

Cold Start

 

 

With the UPS plugged in, press and release the on/off/test button to supply power to the loads.

The loads are immediately powered while the UPS performs a self-test.Press and release the button again to turn off power to the loads. It may be convenient to use the UPS as a master on/off switch for the protected equipment.

The green on-lineLED illuminates when the UPS is supplying utility power to the loads.

Self-test

The UPS performs a self-testautomatically when turned on, and every two weeks thereafter. Automaticself-testeases maintenance requirements by eliminating the need for periodic manual selftests.

During the self-test,the UPS briefly powers the loadson-battery.If the UPS passes theself-test,it returns toon-lineoperation.

If the UPS turns off during the self-testand emits a fading tone, the batteries are not connected properly.

The loads are not affected by a failed test. Recharge the battery pack overnight and perform the self-testagain. If the replace battery LED is still on, replace the battery pack using theReplacing the Battery Pack procedure.

During on-batteryoperation, the yellowon-batteryLED illuminates and the UPS sounds an audible alarm consisting of 4 beeps every 30 seconds. The alarm stops when the UPS returns toon-lineoperation.

Low Battery

When the UPS is operating on-batteryand the energy reserve of the battery pack runs low, the UPS beeps continuously until the UPS shuts down from battery pack exhaustion or returns toon-lineoperation, if the utility power returns before the battery pack is exhausted..

Replace Battery

If the battery pack fails a self-test,the UPS emits short beeps for one minute and the red replace battery LED illuminates.

The UPS repeats the alarm every five hours. Perform the self-testprocedure to confirm replace battery conditions. The alarm stops when the battery pack passes theself-test.

Note: Cold start is not a normal operating condition.

When the UPS is off and there is no utility power, it is possible to cold start the UPS to power the loads from the UPS’s battery pack.

· Press and hold the on/off/test button until the UPS emits a constant tone.

·Release the on/off/test button during the tone to start the UPS.

Overload

When loads exceed the UPS’s capacity, the red overload LED illuminates and the UPS emits a sustained tone. The alarm remains on until the overload is removed. Disconnect nonessential load equipment from the UPS to eliminate the overload.

If the overload is severe, the input circuit breaker may trip (the resettable center plunger of the circuit breaker pops out). Disconnect nonessential load equipment from the UPS to eliminate the overload and press the plunger back in.

If there is AC power and the circuit breaker does not trip during overload, the loads are still powered. If the circuit breaker trips or the UPS attempts to transfer to battery, the loads’power will be shut off. Turn the UPS off then back on to power the loads.

Storage

Storage Conditions

Before storing, charge the UPS for at least 8 hours. Cover the UPS and store it lying flat in a cool, dry location, with its battery pack fully charged.

Extended Storage

At -15to +30°C (+5 to +86°F), charge the UPS’s battery pack every 6 months.

At +30 to +45 °C (+86 to +113°F), charge the UPS’s battery pack every 3 months.

Replacing the Battery Pack

This UPS has an easy to replace hot-swappablebattery pack.

Note: Please read the cautions in the APC Safety Guide.

Replacement Batteries

See your dealer or call the number in this manual for information on replacement battery pack kits. For 250 models, order RBC17. For 450 models, orderRBC18.

Battery Pack Replacement Procedure

Battery pack replacement is a safe procedure, isolated from electrical hazards. You may leave the UPS and loads on for the following procedure.

Notes

·Once the battery pack is disconnected, the loads are not protected from power outages.

·Be careful removing the batteries - they are heavy.

·Small sparks at the battery connectors are normal during connection.

2.Use a flat-bladescrewdriver to turn the two battery door screws ¼ turn counterclockwise; open the door.

3.Grasp the clear plastic tab and gently pull the battery pack out of the UPS until the battery connector is visible.

Warning! Do not force the battery pack out. This may damage internal wiring!

4.Disconnect the battery connector by gripping both sides of the connector and firmly pulling them apart.

5.Slide the battery pack out of the UPS.

6.Slide the new battery pack three-fourthsof the way into the UPS.

7.Connect the battery connector attached to the unit to the connector attached to the new battery pack.

Service

If the UPS requires service do not return it to the dealer! Follow these steps:

1.Use the Troubleshooting section of theQuick Reference Guide to eliminate common problems.

2.Verify that no circuit breakers are tripped. A tripped circuit breaker is the most common UPS problem!

3.If the problem persists, call customer service or visit the APC Internet Website (www.apcc.com).

4.Note the model number of the UPS, the serial number, and the date purchased. A technician will ask you to describe the problem and try to solve it over the phone, if possible. If this is not possible the technician will issue a Return Merchandise Authorization Number (RMA#).

5.If the UPS is under warranty, repairs are free. If not, there is a repair charge.

6.Disconnect the batteries before packing the UPS.

7.Pack the UPS in its original packaging. If the original packing is not available, ask customer service about obtaining a new set.

8.Pack the UPS properly to avoid damage in transit. Never use Styrofoam beads for packaging. Damage sustained in transit is not covered under warranty.
