Turning the UPS On

After the UPS is connected to a power source, the fan turns on and the UPS enters Standby mode. To turn on the UPS, press and hold the button until you hear the UPS beep (approximately one second). The LCD briefly displays On Delay and the ￿indicator illuminates. Then the UPS conducts a self￿test, briefly displaying On BATTERY. If an alarm condition occurs, see Table 10 on page 37.

When the self-test is complete, the LCD displays On Line indicating that power is available from the UPS output receptacles.
