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.
"LINE POWER" (green) LED
(Indicates the presence of utility AC)
"STANDBY POWER" (red) LED
(Indicates inverter operation)
"AC OUTPUT" (green) LED
(Indicates acceptable output voltage)
