Utility Voltage

PROBLEM AND POSSIBLE

CAUSE

SOLUTION

UPS OPERATES ON BATTERY ALTHOUGH NORMAL LINE VOLTAGE EXISTS

UPS input circuit breaker tripped.

Very high, low, or distorted line voltage. Inexpensive fuel powered generators can distort the voltage.

Reduce the load on the UPS by unplugging equipment and resetting the circuit breaker (on the back of UPS) by pressing the plunger in.

Move the UPS to a different outlet on a different circuit. Test the input voltage with the utility voltage display (see below). If acceptable to the connected equipment, reduce the UPS sensitivity.

BATTERY CHARGE AND BATTERY LOAD LEDS FLASH SIMULTANEOUSLY

The internal temperature of the UPS has exceeded the allowable threshold for safe operation.

Check that the room temperature is within the specified limits for opera- tion.

Check that the UPS is properly installed allowing for adequate ventila- tion.

Allow the UPS to cool down. Restart the UPS. If the problem continues contact APC at, www.apc.com/support.

DIAGNOSTIC UTILITY VOLTAGE FEATURE

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 dis-

play. 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.
