Installation and Initial Start-Up

To obtain warranty coverage, please fill out and return the warranty registration card now.


Inspect the 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.


Install the UPS in a protected area that is free of excessive dust and has adequate air flow. Do not operate the UPS where the temperature and humidity is outside the specified limits.

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

Connect to Utility

Operating Instructions

Switch “On” — Switch “Off”

With the UPS plugged in, press and release the On/Off/Test button to supply power to the loads.

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

battery backup loads.


The UPS performs a self-testautomatically when turned “On”, and every two weeks thereafter (by default). Automaticself-testeliminates the need for periodic manualself-tests.

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

If the UPS fails the self-testit immediately returns toon-lineoperation and lights the replace battery LED.

User’s Manual

Check the Site Wiring Fault Indicator

Location: Top right corner of UPS back panel.

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

Connect the Loads

Plug the loads into the output connectors on the rear of the UPS. To use the UPS as a master “On/Off” switch, make sure that all of the loads are switched “On”.

Caution: Do not connect a laser printer to the Battery Backup Outlets.

Battery Backup Outlets: These UPS outlets provide battery power and surge protection to equipment when utility voltage is outside acceptable limits. Data sensitive equipment such as a computer, monitor, or external drive are connected to these outlets.

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


During on-batteryoperation, the on-

battery LED illuminates and the UPS sounds an audible alarm consisting of 4

beeps every 30 seconds. The alarm stops when the UPS returns to on-lineoperation.

Low Battery

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


When loads exceed the UPS capacity,

the 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 battery backup outlets, 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), as well. Disconnect nonessential load equipment from the UPS to eliminate the overload and press the plunger back in to restart the UPS.

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.

Connect Telephone / Network Surge

Suppression (Optional)

Connect a single line telephone or a 10Base-T/100Base-Txnetwork cable into theRJ-45/RJ-11telephone/network surge protection “IN” jack on the back of the UPS. Connect from the “OUT” jack with telephone cable (supplied) or network cabling (not supplied) to a fax modem or network port.

Connect Computer Interface

Port (Optional, BP1050/1100)

PowerChute® plus power management software is included with this UPS. Connect the supplied interface cable to the9-pincomputer interface port on the back panel of the UPS. Connect to the computer. See software documentation for installation instructions.

Charge the battery

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

Replace Battery

If the battery fails a self-test,the UPS emits short beeps for one minute and the 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 passes theself-test.

Shutdown Mode

If there is no power, the host connected to the computer interface port can command the UPS to shut down. This is normally done to preserve battery capacity after a controlled shutdown of the protected system. In shutdown mode the UPS stops supplying power to the load. The online and overload LED indicators flash alternately or, if the UPS has shutdown due to a low battery, the UPS will beep once every 4 seconds for approximately 16 seconds. When line power is restored, the UPS will return to on-lineoperation.

Cold Start

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 battery.

Press and hold the On/Off/Test button until the UPS begins beeping.

Release the On/Off/Test buttonduring the beeping to start the UPS.

Storage conditions

Store the UPS covered and upright in a cool, dry location, with its battery fully charged. Before storing, charge the UPS for at least 4 hours.

Extended storage

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

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

Replacing the Battery

This UPS has an easy to replace hot-swappablebattery. Battery replacement is a safe procedure, isolated from electrical hazards. You may leave the UPS and loads on for the following procedure. See your dealer or call the number in this manual for information on replacement battery kits.

Note: Once the battery is disconnected, the loads are not protected from power outages.


1400 VA

1.Grasp the top of the front cover and tilt it out and down.

2.Unhook the bottom of the cover from the chassis and lift it upward to expose the battery door. Be careful not to strain the ribbon cable. Do not touch the exposed printed circuit board.

3.Fold the front cover on top of the UPS as shown.

4.Use a flat-bladescrewdriver or a coin toremove the two battery door screws and open the door.

5.Grasp the tab and gently pull the battery out of the UPS.

6.Disconnect the battery leads.

For the 1000/1050/1100 VA models, loosen the connectors by gently wiggling them while pulling straight back from the battery connector.

For the 1400 VA model, pull the two gray couplers apart to disconnect the battery.

7.Connect the battery leads to the new battery.

Note: Small sparks at the battery connectors are normal during connection.

For the 1000/1050/1100 VA models, connect the red wire to the positive (+) terminal and the black wire to the negative (–)terminal.

For the 1400 VA model, connect the gray battery coupler to the UPS coupler.

8.Slide the battery into the UPS.

9.Close the battery door,replace the battery compartment screws, and replace the front cover.

10.Dispose of the old battery properly at an appropriate recycling facility or return it to the supplier in the packing material for the new battery. See the new battery instructions for more information.
