Power On Indicator
This LED is illuminated when
the utility condition is normal
and the UPS outlets are pro-
viding clean, protected power.
Line Fault Indicator
This LED will illuminate to warn the user that a
wiring problem such as a bad/missing ground or
reversed wiring exists within the AC receptacle.
If illuminated, disconnect all equipment and contact
an electrician to insure outlet is properly wired.
Unsafe Voltage Indicator
This LED will illuminate to inform the user that
an unsafe line voltage is present and that the
UPS has switched to battery power. This could
be either an over-voltage or under-voltage.
Battery Mode Indicator
This illuminates during utility failure or
an unsafe voltage condition, indicating
that the battery is supplying power to
the connected equipment.
AVR Indicator
This indicates that the UPS is operating in automatic voltage regulation mode. When the LED is
illuminated continuously, it indicates an input over-voltage and the UPS unit reduces (bucks) the
voltage to the normal operating range. When the LED is flashing, it indicates that the input line
voltage is low and that the UPS is increasing (boosts) input voltage to the normal range.
Load Level Indicator
This is a visual indication of the
UPS load.
The
1st
arrow will illuminate when
the load is above 25%, the
2nd
above 50% and the
3rd
above
75%. The
4th
arrow will flash
when the load is between 85%
and 100%.
Battery Level Indicator
This is a visual indication of the
battery charge. If battery capac-
ity is under 25%, no indicator
LED will illuminate and UPS
starts beeping (if the audible
alarm is enabled).

Circuit Breakers for
Overload Protection
Resettable circuit
breakers provide
optimal overload
protection.
Non-Critical-Load Outlets
Four battery powered, surge
protected and AVR outlets for
connected equipment insures
temporary uninterrupted oper-
ation of connected equipment
during a power failure.
Critical Load Outlets
Two battery powered, surge
protected and AVR outlets for
critical-load equipment
insures temporary uninter-
rupted operation of connected
equipment during a power
failure.
IR Control Section
Learning Control Switches – Push to program or test the IR function
IR Detector Window – Receives the IR signal to be learned
Indicator LED’s – Indicates learning status
Output Delay Switches – Sets the desired time delay between a power failure
and when the IR signals are sent to the connected equipment
IR Output Jacks – Standard 1/8” (3.5mm) mono jack for connection to an IR
flasher (IR flashers not included)
RS232 Serial Communication Port
The serial port allows connection and communication between the
UPS and a computer system. This allows the installer to program
a number of variables including the Critical Load Battery Threshold.
See the software documentation for more information.
