2.3 System Status Block

The "SYSTEM STATUS" block is broken into three categories to quickly identify the

power supply's operational status: running on AC line power; running on batteries; and

nominal output power to the load.

2.3.1 "LINE POWER" (green) LED

The green "LINE POWER" LED indicates that power from the utility is present and that

the power supply is operating in AC LINE mode.

2.3.2 "STANDBY POWER" (red) LED

The red "STANDBY POWER" LED indicates that the power supply is operating from

its battery backup. When AC from the utility is lost, the green "LINE POWER" LED goes

OFF and the red "STANDBY POWER" LED comes ON as the unit transfers to inverter

operation. Whenever the red LED is ON, the unit is running on backup power.

2.3.3 "AC OUTPUT" (green) LED

The green "AC OUTPUT" LED indicates that acceptable voltage is available at the

power module's output. Regardless of the input mode, "LINE POWER" or "STANDBY

POWER,"

the "AC OUTPUT" LED should remain ON at all times.
