DIAGNOSTIC UTILITY VOLTAGE FEATURE

Utility Voltage

The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS into the normal utility power.

Press and hold the button to view the utility voltage bar graph display. After

a few seconds the five-LED, Battery Charge, , display on the right of the front panel shows the utility input voltage.

Refer to the figure at left for the voltage reading (values are not listed on the UPS).

The display indicates the voltage is between the displayed value on the list and the next higher value.

Three LEDs light, indicating utility voltage within the normal range.

If no LEDs are lit and the UPS is plugged into a working utility power outlet, the line voltage is extremely low.

If all five LEDs are lit, the line voltage is extremely high and should be checked by an electrician.

The UPS starts a self-test as part of this procedure. The self-test does not affect the voltage display.

If the UPS requires service do not return it to the dealer. Instead, follow these steps:

1.Review the problems discussed in the Troubleshooting section of this manual to eliminate common problems.

2.If the problem persists, contact APC Customer Service through the APC web site, www.apc.com/support.

•Note the model number of the UPS, the serial number, and the date purchased. If you call APC Customer Service, a technician will ask you to describe the problem and try to solve it over the phone, if possible. If this is not possible, the technician will issue a Returned Material Authorization Number (RMA#).

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

3.Pack the UPS in its original packaging. If the original packing is not available, refer to the APC web site, www.apc.com/support, for information about obtaining a new set.

•Pack the UPS properly to avoid damage in transit. Never use Styrofoam beads for packaging. Damage sustained in transit is not covered under warranty.

Always DISCONNECT THE BATTERY before shipping in compliance with U.S. Department of Trans- portation (DOT) regulations.

The battery may remain in the UPS; it does not have to be removed.

4.Mark the RMA# on the outside of the package.

5.Return the UPS by insured, prepaid carrier to the address given to you by Customer Service.
