BR500CI-AS User Guide

1These outlets are powered whenever the Back-UPS is switched ON. During a power outage, or other utility problems (brownouts, over-voltages), these outlets will be powered for a limited time by the Back-UPS. Plug the computer and monitor into these two outlets.

Connect Equipment

Battery Backup Surge Protection

Connect AC Power Cord

Plug the Back-UPS power cord into a wall outlet, not a surge protector or power strip. The outlet should be near the equipment and easily accessible.

Place the Back-UPS to avoid:

–Direct sunlight

–Excessive heat

–Excessive humidity or contact with fluids

2Connect the Battery and Turn on the Unit

Connect the battery to the UPS before use. To connect the battery:

Pull the top of the battery connector lever out of the unit, until the lever is horizontal.

Push the battery connector lever completely into the unit, until the end of the lever is flush with the rear panel. Press ON/OFF to turn on the unit.

A single short beep, and the green “Power On” indicator confirms that the Back-UPS is on and ready to provide protection.

The Back-UPS should charge for at least 10 hours to ensure sufficient runtime. The unit is being charged whenever it is connected to utility power, whether the unit is turned ON or OFF.

3 Adjusting Transfer

Voltage and Sensitivity

Settings

Automatic Voltage Regulation boosts the utility voltage when it drops below safe levels. This allows the equipment plugged into the unit to operate during low voltage conditions, conserving the battery power in the event of a power outage.

The Back-UPS will switch to battery power if the input voltage level becomes too low for the Automatic Voltage Regulation to compensate, or if the utility power is distorted.

If the Back-UPS switches to battery power too frequently or too infrequently, adjust the transfer voltage and sensitivity settings:

1.Ensure the Back-UPS is off. Plug it into utility power.

2.Press and hold ON/OFF until the LED repeatedly flashes. The unit is now in Program Mode.

3.Release the button. The LED will flash once, twice, or three times per second, indicating the current setting. See Transfer Voltage and Sensitivity Settings.

4.Press ON/OFF within two seconds to change the setting. Each time the button is pressed, the LED will flash at a different rate: once, twice, or three times per second, indicating the new setting. Continue pressing the button until the desired setting is reached. If the button is not pressed within five seconds, the Back-UPS will exit the Program Mode.

5.To exit Program Mode, release the button and wait for the LED to stop flashing.

Status Indicators

The Back-UPS indicates its operating status using a combination of visual and audible indicators.

Power On LED	Buzzer	Condition
On	Off	On-line- Back-UPS is supplying conditioned utility power
		to the connected equipment
On (Off during 4	4 beeps repeated	On-Battery- Back-UPS is supplying battery power
beeps)	every 30 seconds
Flashing	Rapid Beeping	Low Battery Warning - The Back-UPS has 1.5 minutes of
	(every 1/2 second)	remaining battery power
Flashing	Constant tone	Bad Battery Detected - Battery needs to be charged, or is
		at end of life. (See Battery Replacement.)
Off	Short beep every	Low Battery Shutdown - During On Battery operation the
	4 seconds	battery power was almost completely exhausted, and the
		Back-UPS is waiting for utility power to return to normal
Off	Constant Tone	On Battery Overload - Connected equipment requires
		more power than provided by the Back-UPS battery.
		Unplug devices one at a time to remove overload, if not
		corrected Contact APC Technical Support
On	Constant Tone	On Line Overload - The power drawn by the connected
		equipment exceeds the power capacity of the Battery
		Backup
Flashing	Chirp every 2	Charger Warning -Back-UPS has experienced an internal
	seconds	problem, but continues to power the load. Contact APC
		Technical Support
Off	Constant Tone	Charger Fault - Back-UPS has an internal problem, and is
		no longer powering the load. Contact APC Technical
		Support

Transfer Voltage and Sensitivity Settings

		Transfer Voltage	Input Voltage
	LED Flashing		Range	Usage
		Setting	(For Utility
			Operation)
	Once per second	Low	155 - 280	The Back-UPS will switch to battery power less often. Use with equipment that is not
				sensitive to low or high level voltage levels or minor voltage waveform distortions.
	Twice per second	Medium	160 -280	Default, use in normal conditions.
		(factory default)
	Three times per second	High	165 - 270	The Back-UPS will switch to battery power during any small fluctuation in voltage.
				Use with equipment that is sensitive to low or high level voltage levels or minor
				voltage waveform distortions.
