Status Indicators and Alarms Replace the Internal Battery

There are four status indicators (lights) on the front panel of the Back-UPS (On Line, On Battery, Overload, and Replace Battery).

ON LINE

Overload (red) - is lit whenever power demand has exceeded the capacity of the Back-UPS.

Continuous Tone - this alarm is sounded whenever the Battery Backup outlets are overloaded.

To replace the internal battery, proceed as follows:

Note: Replacing the battery is a safe procedure. However, small sparks may occur during the process. This is normal.

ON BATTERY

OVERLOAD

REPLACE BATTERY

On Line (green) - is lit whenever utility power is powering the Battery Backup outlets.

On Battery (yellow) - is lit whenever

the battery of the Back-UPS is powering equipment connected to the Battery Backup Outlets.

Four Beeps Every 30 Seconds - this alarm is sounded whenever the Back- UPS is running On Battery. Consider saving work in progress.

Circuit Breaker - the circuit breaker button located on the rear panel of the Back-UPS will stick out if an overload condition forces the Back-UPS to disconnect itself from utility power. If the button sticks out, disconnect non- essential equipment. Reset the circuit breaker by pushing the button inward.

Replace Battery (red) - is lit when- ever the battery is near the end of its use- ful life, or if the battery is not connected (see above). A battery that is near the end of its useful life has insufficient run- time and should be replaced.

Chirps for 1 Minute Every 5 Hours - this alarm is sounded whenever the battery has failed the automatic

Transfer Voltage Adjustment (optional)

In situations where the Back-UPS or connected equipment appears too sensitive to input voltage, it may be necessary to adjust the transfer voltage. This is a simple task requiring use of the front panel pushbutton. To adjust the transfer voltage, proceed as follows:

1.Plug the Back-UPS into the utility power source. The Back-UPS will be in a Standby Mode (no indicators lit).

2.Press the front panel pushbutton fully inward for 10 seconds. All indicators on the Back-UPS will flash to acknowledge going into Programming Mode.

3.The Back-UPS will then indicate its current Lower Transfer Voltage, as shown in the following table.

Indicators Lit	Lower Transfer Voltage	Use When
1	160 VAC	Back-UPS frequently goes On Battery due to
		low input voltage.
2	180 VAC (factory default)	Normal power conditions exist.
3	196 VAC	Connected equipment is sensitive to low voltage.

4.To select 160 volts as the Lower Transfer Voltage, press the pushbutton until 1 indicator is flashing.

5.To select 180 volts as the Lower Transfer Voltage, press the pushbutton until 2 indicators are flashing.

6.To select 196 volts as the Lower Transfer Voltage, press the pushbutton until 3 indicators are flashing.

7.Once in Programming Mode, if the pushbutton is not pressed within 5 seconds, the Back-UPS will exit the Programming Mode, and all indicators will extinguish.

Order Replacement Battery

The typical battery lifetime is 3-6 years (depending on the number of discharge cycles and operating temperature). A replacement battery can be ordered over the phone from APC, or the battery can be ordered on-line from the APC web site (see below, a valid credit card is required).

When ordering, please specify Battery Cartridge RBC2.

Back-UPS Storage

Before storing, charge the Back-UPS for at least eight hours. Store the Back-UPS covered and upright in a cool, dry location. During storage, recharge the battery in accordance with the following table:

Storage Temperature	Recharge Frequency	Charging Duration
-5oto 30oC (23o to 86oF)	Every 6 months	8 hours
30o to 45oC (86o to 113oF)	Every 3 months	8 hours

Please contact APC Technical Support to troubleshoot the unit before returning it to APC.
