UNIT DESCRIPTION
1. Main Power Switch: Turns on all UPS functions except the internal battery charger. Charger
operates when UPS is connected to commercial power.
2. Test Button: Depressing this button causes the UPS to switch to the Inverter mode (backup)
for test.
3. Backup/Fault LED: In Inverter mode, LED illuminates momentarily along with the audible
alarm. If UPS goes to low battery, overload or software-generated shutdown while in Inverter
mode, UPS shuts down. On AC return, UPS goes to AC mode, and Fault and Alarm operate
continuously. The Fault is reset either by pressing Test or any subsequent loss of power and
successful return to AC. During normal Inverter mode, alarm sounds once every 15 seconds,
changing to once every two seconds at low battery warning.
4. Normal LED: On in normal AC mode when commercial power is present; otherwise off.
5. Input Power Cord: A300, A425 and A2000 use a standard strain relieved power cord. Other
models use IEC 320 male socket and a cord set.
