Basic Operation
LCD Screen
The LCD screen displays a variety of UPS modes and operating conditions. To view, press the mute button
on-line AC power mode or battery power mode.
The LCD screen shown here is fully illuminated to identify all available icons and labels. This is for illustrative purposes only—there are no
operating modes where the screen fully illuminates, except for a few seconds when the UPS is first plugged in.
Operating Mode Indicators
ON-LINE MODE ICON indicates that AC power is present and
1
the UPS is running from an input line power source.
AVR BOOST ICONS will selectively illuminate during line
2
power mode to indicate Automatic Voltage Regulation (AVR) is
engaged. "AVR" indicates an overvoltage condition and output
is reduced back to usable levels. "AVR" also indicates brownout/
undervoltage conditions and when output is boosted back to
usable levels.
ON BATT ICON indicates that the UPS is running in battery
3
mode, due to power failure or severe input voltage fluctuation.
REPLACE BATTERY ICON will illuminate to inform users that the
4
UPS battery is weak and requires replacement.
Battery Indicators
BATTERY CHARGE METER continuously reports battery charge
5
level.
LOAD LEVEL METER continuously reports load-level on UPS
6
supported outlets.
OVERLOAD ICON comes on to report that UPS supported
7
outlets are overloaded.

Additional Display Items
3-DIGIT DISPLAY lights along with associated labeling and icons
8
to report a variety of UPS and site power related conditions.
3-DIGIT DISPLAY SUFFIX display labels will selectively
9
illuminate to describe the unit of measurement the 3-digit
display is currently reporting (V=volts, %=percent, A=amps,
kW=kilowatts, Hz=frequency, Min=minutes, VA=Volt Amps).
3-DIGIT DISPLAY PREFIXES
10
• INPUT lights to indicate the 3-digit display is reporting an input
condition (input voltage, input frequency)
• OUTPUT lights to indicate the 3-digit display is reporting an
output condition (output voltage, output Hz, etc)
• RUNTIME ESTIMATE lights to indicate that the 3-digit display is
currently reporting estimated runtime in minutes
SW ICON indicates a wiring fault has been detected. If this icon
11
illuminates at any time the unit is plugged in, the fault should
be repaired by a qualified electrician as soon as possible. This
icon indicates that phases are reversed, ground is missing or
some other sort of wiring error exists in the circuit the UPS is
plugged into. The site wiring fault detector circuitry will identify
most common wiring faults, but will not necessarily detect every
possible type of fault.
ECO ICON indicates the ECO feature is enabled. The ECO icon
12
will not display if the ECO feature is disabled.
