APC Smart-UPS®

1000/750VA 230/120/100VAC 1U Rack Mount Uninterruptible Power Supply



American Power Conversion Corporation (APC) is the leading national and international manufacturer of state-of-the-artuninterruptible power supplies, redundant switches, power management software, and related equipment. APC products protect hardware, software, and data from power disturbances in business and government offices throughout the world.

The APC Uninterruptible Power Supply (UPS) is designed to prevent blackouts, brownouts, sags, and surges from reaching your computer and other valuable electronic equipment. The UPS filters small utility line fluctuations and isolates your equipment from large disturbances by internally disconnecting from the utility line. The UPS provides continuous power from its internal battery until the utility line returns to safe levels or the battery is discharged.


Read the Safety Instruction sheet before installing the UPS.


Inspect the UPS upon receipt. APC designed robust packaging for your product. However, accidents and damage may occur during shipment. Notify the carrier and dealer if there is damage.

The packaging is recyclable; save it for reuse or dispose of it properly.

Check the package contents. The package contains the UPS, the front bezel, a literature kit containing one CD, one serial cable, one USB cable, product documentation and Safety Information. The package also includes rails, brackets, and a hardware packet, (necessary for rack mounting the UPS).

230V models: Two IEC jumper cables are included and a utility connector plug is included for use on servers with permanently attached power cords.

The UPS is shipped with the battery disconnected.

Positioning the UPS

Place the UPS where it will be used. The UPS is heavy. Select a location sturdy enough to handle the weight.

Do not operate the UPS where there is excessive dust or the temperature and humidity are outside the specified limits.

Connecting Equipment and Power to the UPS


230V Models

120/100V Models


1.Connect equipment to the UPS. Note: Do not connect a laser printer to the UPS. A laser printer draws significantly more power than other types of equipment and may overload the UPS.

2.Add any optional accessories to the Smart-Slot.

3.Using a power cord, plug the UPS into a two-pole,three-wire,grounded receptacle only. Avoid using extension cords.

120/100V models: The power cord is permanently attached to the rear panel of the UPS.

4.Turn on all connected equipment. To use the UPS as a master ON/OFF switch, be sure all connected equipment is switched ON. The equipment will not be powered until the UPS is turned on.

5.To power up the UPS press the button on the front panel.

The UPS charges its battery when it is connected to utility power. The battery charges to 90% capacity during the first three hours of normal operation. Do not expect full battery run capability during this initial charge period.

120V Models: Check the site wiring fault LED located on the rear panel. It lights up if the UPS is plugged into an improperly wired utility power outlet. Refer toTroubleshooting in this manual.

6.For additional computer system security, install PowerChutePlus® Smart-UPSmonitoring software.


Serial Port

USB Port Power management software and interface kits can be used with the


UPS. Use only interface kits supplied or approved by APC.

Use an APC supplied cable to connect to the Serial Port. DO NOT use a standard serial interface cable since it is incompatible with the UPS connector.

Both Serial and USB Ports are provided. They cannot be used simultaneously.

Manual Self-Test

This LED illuminates to indicate the UPS is compensating for a high utility voltage.

This LED illuminates to indicate the UPS is compensating for a low utility voltage.

When the on battery power LED is lit the UPS is supplying battery power to the connected equipment. When on battery, the UPS sounds analarm—fourbeeps every 30 seconds.

The LED illuminates and the UPS emits a sustained alarm tone when an overload condition occurs.

Failure of a battery self-testcauses the UPS to emit short beeps for one minute and thereplace battery LED illuminates. Refer to

Troubleshooting in this manual.

The replace battery LED flashes and short beep is emitted every two seconds to indicate the battery is disconnected.

The UPS performs a self-testautomatically when turned on, and every two weeks thereafter (by default).

During the self-test,the UPS briefly operates the connected equipment on battery.

If the UPS fails the self-test,thereplace battery LEDlights and immediately returns to online operation. The connected equipment is not affected by a failed test. Recharge the battery for 24 hours and perform anotherself-test.If it fails, the battery must be replaced.

Press and hold the button for a few seconds to initiate theself-test.

On Battery Operation

The Smart-UPSswitches to battery operation automatically if the utility power fails. While running on battery, an alarm beeps four times every 30 seconds.

Press the button (front panel) to silence the UPS alarm (for the current alarm only). If the utility power does not return, the UPS continues to supply power to the connected equipment until the battery is exhausted.

If PowerChute is not being used you must manually save your files and power down before the UPS turns off.


UPS battery life differs based on usage and environment. It is recommended that the battery/batteries be changed once every three years. See the APC web site,, for on battery run times.
