1.0 INTRODUCTION
Manual Overview
This user manual has been written to provide basic information about the Falcon XG Series
UPS Plus. XG models are available in nominal power ratings of 1500, 2200 and 3000 VA . The
XG Series is a compact, double conversion, “on-line” UPS. It provides continuous power
conditioning, tight output voltage regulation and a true sinewave output. The XG Series UPS
protects your sensitive electronics equipment against the widest range of power problems,
including power failures, power sags, power surges, brownouts, line noise, high voltage
spikes, frequency variations, switching transients, and harmonic distortion.
This manual also describes unpacking, unit installation, the major features of XG series UPS,
as well as detailing operation, configuration and troubleshooting.
The specifications section states all of the detailed parameters of operation for the Series, and
provides general information on approvals and certifications.
Brief XG Overview
The Falcon XG Series UPS may be installed in either of two formats. Brackets are supplied to
facilitate installation into a standard 2U, 19 inch equipment rack slot, or free-standing on a
table top in a mini-tower tower format.
The XG Series front panel features includes a graphical LCD display to indicate the status of
the operation. The display enables the user or field service engineer to easily monitor and
troubleshoot localized power problems, in addition to UPS operation. UPS control is
accomplished through STANDBY, FUNCTION/TEST and SET/ALARM SILENCE buttons. Two
levels of audible alarms are also provided when the unit is operating on battery.
The XG Series rear panel has an RS-232 port to provide communications between the UPS and
a network server or other computer systems. This port when used along with the supplied
UPSILON software, gives the ability to remotely test the UPS, set UPS parameters, monitor
power status. The software will also automatically save open computer files and initiate an
unattended shutdown, in the event of a loss of utility.

BLOCK DIAGRAM
2.0 CIRCUIT DESCRIPTIONS
INPUT FILTER
This internal UPS circuit provides surge protection, certified to meet IEC 61000-4-5 and IEC
801-5. It also filters both electro-magnetic interference (EMI) and radio frequency interference
(RFI). It minimizes surges or RFI interference present on the utility line.
CURRENT AND POWER FACTOR REGULATOR
In normal operation, this circuit converters utility AC power to regulated DC power for inverter
use. It ensures the input current maintains a sine waveform to minimize the amount of current
distortion that will be reflected to the utility. The XG Series UPS can tolerate a wide input
range and has an overload power factor regulator alarm to alert the user in the event the UPS
has an excessively heavy output load, while operation from a utility source with abnormally
low input voltage.
DC/DC CONVERTER
The DC/DC converter utilizes energy from battery and boosts up the DC bus voltage to a level
required by the inverter. This allows the inverter to operate continuously at optimum
efficiency and voltage. The converter has a patented circuit which reduces the amount of
ripple current and EMI interference to the battery.
DC/AC INVERTER
In normal on-line operation, the Inverter utilizes the regulated DC output to invert DC back into
clean, regulated sinewave AC power. When utility power fails, the inverter will receive its
energy from the battery through the DC/DC converter. In both modes of operation, the UPS
inverter is on-line and continuously generating clean, regulated AC output power to the load.
The XG Series has a pure sinewave output, which is produced with a Pulse Width Modulation
(PWM) Inverter. As a result, the UPS output is very stable, even with nonlinear loads.

6
BATTERY
The XG Series UPS utilizes a flame retardant battery pack comprised of four 12V 7 AH, valve-
regulated, and sealed lead acid batteries. All XG battery packs are interchangeable. They are
easy to install or change. To maintain battery design life, the user should operate the UPS in
an ambient temperature of 68
o
F to 77
o
F (20
o
C to 25
o
C). Extended Battery modules are available
to provide extend battery run times.
CHARGER
The battery charger uses the energy from the utility power to continuously charge the UPS
batteries. The charger operates in “constant power” mode. The UPS batteries are being
charged whenever the UPS is plugged in. The charger will continue to operate as long as the
utility voltage is over 60 Vac.
BYPASS TRANSFER SWITCH
The XG Series UPS automatically switches to bypass to energize the connected load when
UPS encounters an overload, over temperature, over input current, over crest-factor load
(designed for 3:1 nonlinear load), or a UPS failure condition. Should any of these events
occur, the UPS will automatically transfer to bypass mode with an audible alarm, and provide
a “bypass” indication on the LCD display.
OUTPUT FILTER
This filter prevents electro-magnetic conductance (EMC) leakage and RFI noise to the UPS
output.

5.0 OPERATION
OPERATING MODES
The display shows the UPS status through the graph LCD for each mode .
NORMAL ON-LINE MODE
During normal on-line operation, utility power provides energy to the UPS. The filters, power
factor corrector and the inverter process the power to provide computer grade power to
connected loads. The UPS maintains the batteries in a fully charged state.
All indicators are stable except Alarm Buzzer. The LCD displays
the % of load, Inverter, PFC, Line, Charger and Battery. The Fan is
at medium speed.
The Solid line shows the power flow from input to load and
battery. The load is being powered from the UPS inverter.
BATTERY MODE
Battery mode is displayed during high input voltage conditions or a utility power failure. When
in battery mode, the UPS battery supplies energy through the DC to DC converter to the
Inverter to power the connected load. During the battery discharging, the audible alarm beeps.
The rate of the beeping will increase as the battery runs low (low battery), prior to UPS shut
down. Once this warning is sounded, you have less than a minute of battery runtime left.
When utility power has been restored, after UPS has shutdown, the UPS will automatically
restart. For approximate battery run times, refer to the Battery Run Time charts in this manual.
The run-time is based on a resistive load and an ambient temperature of 77
o
F (25
o
C)
The Display shows the UPS in BATTERY MODE. The solid line is
from battery to inverter with boost illuminated. The Fan high
speed mode is illuminated. The bars, in the battery display
indicate the amount of battery capacity remaining; each bar
represents a 25% capacity level. As capacity decreases, fewer
bars remain illuminated. When the input voltage returns, the
charger indicator will illuminate.

16
BYPASS MODE
The UPS will automatically go to BYPASS mode in the event it is overloaded or suffers an
internal failure. When in bypass, the UPS will transfer the connected loads directly to utility
power. When in bypass mode, BATTERY MODE will not be available. However, the utility
power continues to be passively filtered by the UPS. The UPS will sound an audible alarm and
switch to BYPASS MODE automatically when:
•The UPS has an overtemperature condition.
•The UPS has an overload condition of 101 to 110% over 120 seconds.
•The UPS has an overload condition of 111 to 150% over 20 seconds.
•The UPS has an overload condition of over 150%.
•The UPS detects a fault in the battery or UPS electronics.
The display shows the UPS in BYPASS MODE. The solid line is
connected from the Input to Load. Another solid line is connected
from the Input to Battery in charging. The Fan is in low speed;
Line and Charger icons are illuminated.
GREEN MODE
When Green Mode is turned on, the XG unit is automatically switched to “GREEN MODE”,
once the connected load drops to less than 3% of the UPS rated output. The load will operate
directly from utility power, similar to BYPASS MODE. The display indicates the UPS is in
BYPASS MODE, with a flash “GREEN MODE BULB”. If the load is increased to over 3% of the
UPS output rating, the UPS will switch back to NORMAL ON-LINE operation. All XG models
are shipped from the factory with GREEN MODE turned off. To enable “GREEN MODE”, refer
to the section on UPS “CONFIGURATION”. See the green mode configuration section for
further details and cautions.
TURNING THE UPS ON
Once installation is complete, the UPS can be powered up. With utility power present, turn on
the UPS INPUT BREAKER. The UPS will enter Auto-Start State; all of the indicators on the
display are illuminated. Ten seconds later, the unit goes to ON-LINE operation.
