Symbols and LEDs
What It Means
Steady: Acceptable input power is present. The unit is
running on line power.
Off: No input power is present or the unit is switched off.
The unit is running on battery power.
Output Overload: Refer to Tables 3 and 4.
Replace the battery or UPS Fault. Refer to Tables 3 and 4
Blinking: The unit is boosting or bucking utility power.
Boost = Automatically increases low input power to prevent
the unit from switching to battery.
Buck = Automatically decreases high input power to prevent
the unit from switching to battery.

Symbols, LEDs and Audible Alarms
The front panel LEDs and an audible alarm indicate the unit status. The unit beeps whenever the
unit is on battery power or an alarm is present. See Table 3 for information on beep coding.
In the figure below, bucking means that SOLA 325 is reducing high input voltage, and boosting
means SOLA 325 is increasing low input voltage.
A
B
C
D
Steady: SOLA 325 is operating on AC line.
Steady: SOLA 325 is operating on batteries.
AC Line Operation:
A, B, C and D indicate
percent of full load.
A, B, C & D with D flashing,
load = 110% or higher.
A, B, C & D = 75 - 100%
A, B & C = 50 -75%
A & B = 25 - 50%
A = 0 - 25%
Battery Operation:
A, B, C and D indicate
battery charge.
A, B, C & D = 75 - 100%.
B, C & D = 50 - 75%
C & D = 25 - 50%
D = 0 - 25%; when D is
flashing, less than 2 minutes
of runtime remain.
Blinking: SOLA 325 is bucking or
boosting input AC line.
Blinking = ALARM Condition
C = UPS shutdown due to output overload time-out
B = UPS failed the battery test
B & C = UPS shutdown due to command from
cummunication (RS232, remote shutdown
or External SNMP)
A & B = UPS shutdown due to main relay failure or
short circuit on output
A = UPS Fault (overcharge)
