About Your New PowerStack UPS
Troubleshooting
This Uninterruptible Power Supply (UPS) is designed to prevent
blackouts, brownouts, sags and surges from reaching your computer
and other valuable electronic equipment. This UPS also filters out
small utility line fluctuations and isolates your equipment from large
disturbances by internally disconnecting from the utility line, while
supplying power from its internal batteries until the utility line
returns to safe levels.
Use the chart below to solve minor UPS installation problems.
Contact APC for assistance with complex UPS problems. See the
User’s Manual for a location near you.
While running on battery, an internal alarm will sound (periodic
beeps).
If the utility power does not return, the UPS will continue supplying
power to the connected equipment until exhausted. A continuous
beeping will sound two minutes before the UPS’s final low battery
shutdown. If using a computer, you must manually save your files
and power down before the UPS turns itself off.

Operating Modes
Shutdown Mode
In shutdown mode the UPS stops supplying power to the load, waiting for the return of utility power. If there is no utility power
present, external devices (e.g., servers) connected to the computer interface can command the UPS to shut down. This is normally done
to preserve battery capacity after the graceful shutdown of protected servers. The on-line and overload LEDs will blink alternately
when the UPS is in shutdown mode.
Self-test
The UPS performs a self-test automatically when turned on, and every two weeks thereafter (by default). Automatic self-test eases
maintenance requirements by eliminating the need for periodic manual self-tests.
During the self-test, the UPS briefly operates the loads on-battery. If the UPS passes the self-test, it returns to on-line operation.
If the UPS fails the self-test it immediately returns to on-line operation and lights the replace battery LED.
The loads are not affected by a failed test. Recharge the battery overnight and perform the self-test again. If the replace battery LED is
still on, replace the battery using the procedure described in Replacing the Battery Pack, page 8.
Low Battery
When the UPS is operating on-battery and the energy reserve of the battery runs low, the UPS beeps continuously until the UPS shuts
down from battery exhaustion or returns to on-line operation.
Cold Start
When the UPS is off and there is no utility power, use the cold start feature to apply power to the loads from the UPS’s battery.
Note: Cold start is not a normal condition.
•
Press and hold the on/off/test button until the UPS emits a constant tone.
• Release the on/off/test button during the tone to start the UPS.
Storage
Storage Conditions
Store the UPS covered and upright in a cool, dry location, with its battery fully charged. Before storing, charge the UPS for at least four
hours.
Extended Storage
At -15 to +30 °C (+5 to +86 °F), charge the UPS’s battery every 6 months.
At +30 to +45 °C (+86 to +113 °F), charge the UPS’s battery every 3 months.
