Transfer Voltage Adjustment (optional)

In situations where the Back-UPS RS 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 RS into a utility power source. The Back-UPS RS 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 RS will flash to acknowledge going into Programming Mode.

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

Indicators Lit	Low Transfer Voltage	Use When
1	166 VAC (default)	Normal power conditions exist.
2	160 VAC	Back-UPS RS frequently goes On Battery due to low input voltage.
3	154 VAC	Use only for extreme conditions of low input voltage.
		Not recommended for computer loads.

1.To select 166 volts as the Lower Transfer Voltage, press the pushbutton until 1 indicator is flashing.

2.To select 160 volts as the Lower Transfer Voltage, press the pushbutton until 2 indicators are flashing.

3.To select 154 volts as the Lower Transfer Voltage, press the pushbutton until 3 indicators are flashing. Once in Programming Mode, if the pushbutton is not pressed within 5 seconds, the Back-UPS RS will exit the Programming Mode and all indicators will extinguish.

When selecting 154 volts and the Lower Transfer Voltage, the output current is limited to 2.2 amps to prevent the product from overheating.

Service

Note: If the Back-UPS RS requires service, do not return it to the dealer. The following steps should be taken.

1.Consult the Troubleshooting section to eliminate common problems.

2.Determine if the circuit breaker is tripped. If the circuit breaker is tripped, reset the breaker and determine if the problem still exists.

3.If the problem persists, consult the APC Worldwide Web site (www.apcc.com) or call customer service.

•Record the model number of the Back-UPS RS, the serial number, and the date purchased. Be prepared to troubleshoot the problem over the telephone with a technician. If this is not successful, the technician will issue a Return Merchandise Authorization Number (RMA#) and a shipping address.

•If the Back-UPS RS is under warranty, repairs are free. If not, there is a repair charge.

4.Pack the Back-UPS RS in its original packaging. If the original packing is not available, ask customer service about obtaining a new set. Pack the UPS properly to avoid damage in transit.

Note: Never use StyrofoamTM beads for packaging. Damage sustained in transit is not covered under warranty (insuring the package for full value is recommended).

5.Write the RMA# on the outside of the package.

6.Return the Back-UPS RS by insured, prepaid carrier to the address provided by customer service.

Warranty

The standard warranty is two (2) years from the date of purchase. APC’s standard procedure is to replace the original unit with a factory reconditioned unit. Customers who must have the original unit back due to assigned asset tags and set depreciation schedules must declare such a need at first contact with an APC Technical Support representative. APC will ship the replacement unit once the defective unit has been received by the repair department, or cross ship upon the receipt of a valid credit card number. The customer pays for shipping the unit to APC. APC pays ground freight transportation costs to ship the replacement to the customer.

Replace the Internal Battery

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.
