1.0 INTRODUCTION

Manual Overview

This user manual has been written to provide basic information about Falcon FN Series -2TXI models. The
FN Series is a rugged, double conversion, "on-line" UPS. It has galvanic output isolation configured for a
split-phase (3 wire plus ground) 120/240Vac output. The FN Series provides continuous power conditioning
and accepts a wide range input voltage, while providing tight output voltage regulation, with a true sinewave
output. The FN Series UPS is specifically designed to protect sensitive computers and equipment against the
widest range of power problems. These problems include power failures, voltage sags, voltage surges,
brownouts, utility line noise, high voltage spikes, frequency variations, common mode noise, switching
transients, and harmonic distortion.

This manual also details unpacking, unit installation and the major features of the FN Series UPS, in addition
to detailed UPS operation, configuration and troubleshooting information.

The specifications section at the end of this manual provides detailed operating parameters and general
information on approvals and certifications.

FN UPS Overview

The Falcon FN Series UPS is designed to be easily installed in a floor standing configuration.

The FN Series front panel features a graphical LCD display, providing detailed operational information at a
glance. The display enables the user or field service engineer to easily monitor and troubleshoot localized
power problems, in addition to UPS operation. UPS control and programming are easily accessed using
push buttons located adjacent to the LCD display.

All FN -2TXI model rear panels have the following features and functions:

a. Two input Circuit Breakers. Bypass and UPS input circuit breakers are provided as supplemental
protection devices. The UPS circuit breaker acts as the main on/off switchs for the UPS. It may be
turned off to simulate a utility power loss or for performing battery runtime testing. The UPS can be
completely shutdown when both the UPS and bypass circuit breakers are turned off, and the “Off”
push button is depressed.

b. Single-phase 208-240Vac, 2 wire plus ground, hardwire input on a common terminal block.

c. Split-phase 120/240Vac, 3 wire plus ground, hardwire output on a common terminal block.

d. RS-232 Port - This port may be used to provide communications between the UPS and a network server

or other computer system. When used in conjunction with the supplied UPSilon software, remote UPS
monitoring and control are facilitated. The software will automatically save all open computer files and initiate
an unattended, orderly operating system shutdown in the event of a utility power outage. UPSilon supports
most MS Windows and Linux operating systems. An optional UNIX version is available through Falcon at an
additional cost.

e. Two Communications Option Board Expansion Slots - The slots support the installation of an

optional SNMP/HTTP Agent or contact closure interface boards. The SNMP/HTTP Agent board is a TCP-IP
addressable solution to remote UPS monitoring and management via LAN, WAN or the Internet. The agent
board is supplied with client software that will remotely shut down multiple servers or computers through the
Ethernet LAN. A CD containing software clients and a SNMP MIB II compliant MIB is provided that supports
most popular operations systems.

f. Two RJ45 connectors for connection of UPS parallel operation or remote maintenance

bypass interface cables.

Used when (2) or more FN -2TXI units are connected in parallel.

WARNING: Only FN models of identical power ratings may be connected in parallel. For example, a
FN3K-2TXI may only be connected in parallel with another FN3K-2TXI unit. The FN5K-2TXI may only be
connected in parallel with another FN5K-2TXI. The same is true for the FN6K-2TXI model.

6

g. One Local Maintenance Bypass Switch. The switch provides a manual means of placing the UPS

into bypass mode to allow for minor servicing to be performed on the UPS.

2.0 FN UPS CIRCUIT DESCRIPTIONS

Galvanically Isolated Output

The FN -2TXI models provide a galvanically isolated, 120/240Vac, hardwire output. To meet UL and code
requirements, a dedicated electrical panel should be provided by your electrical contractor or electrician. The
FN -2TXI output configuration gives the required split-phase output necessary to hardwire the UPS to most
standard 3 wire plus ground type electrical panels. This both allows for the use of readily available branch
rated circuit breakers and simplifies the distribution to 240Vac and 120Vac loads. The outputs of up to four
FN -2TXI units may be connected in parallel. Please refer to pages 12-13 of this manual for wiring details.

Additionally, the FN galvanic output isolation in conjunction with a derived neutral greatly reduces common
mode noise and ground loops.

Input & Power Factor Correction

All FN -2TXI models require a 2 wire plus ground type 208-240Vac at 50 or 60Hz. Each FN -2TXI unit input
must be connected to a dedicated circuit having a branch rated circuit breaker. If multiple FN units are to be
connected in parallel, care must be taken to verify the source electrical panel has enough capacity. It must be
rated to supply the total power requirements of the FN Series units, all optional extended battery chargers,
and any other circuits that may be connected to the panel. Please have your electrical contractor review the
FN datasheet located at the end of this manual and perform a site survey several weeks in advance of the
installation date.

While the FN Series UPS is operating from the utility power, the power factor correction circuit converts
utility AC power into regulated DC power for inverter use. The circuit corrects the input current to maintain a
sine waveform to minimize the amount of current distortion that will be reflected back to the utility.

DC/DC Converter

The DC/DC converter utilizes energy from the batteries and boosts up the DC voltage to a level required by
the inverter. This allows the inverter to operate continuously at optimum efficiency and voltage. The converter
incorporates a patented circuit which reduces the amount of ripple current and EMI interference to the battery,
increasing the overall battery life.

DC/AC Inverter

In utility mode operation, the inverter utilizes the regulated DC output and converts it 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 online and continuously
generates clean, regulated AC output power to the load. The IGBT, PWM inverter is of a very robust design
and produces a pure sinewave output with a +/-2% voltage regulation. Having a very low output impedance, it
can supply the high current demands of high inrush and non-linear loads.

Battery Packs

FN -2TXI models utilize flame retardant batteries packaged in (5) user-replaceable, hot-swappable packs that
are accessible by removing the UPS lower front panel. There are (4) 12V, 7AH valve-regulated, sealed lead
acid (VRLA) batteries in each pack (Yuasa NP7-12). See replacement instructions on page 38.

To maintain the optimum battery life, the UPS should be installed in an environment with an ambient
temperature of 68ºF to 77ºF (20ºC to 25ºC). Due to the battery manufacturer specification, the FN Series UPS
batteries may be operated at 32ºF to 104ºF (0ºC - 40ºC), but battery life will be substantially reduced if contin­uously operated at the higher temperature levels. Optional extended battery banks and charger
modules are available through Falcon to extend the amount of battery runtime.

Internal Battery Charger

The internal UPS battery charger utilizes 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, turned on and operating from utility power. The internal UPS battery charger output is
rated at 1.9 amps.

Static Bypass Function

NOTE: Bypass power will only be available If the bypass input is connected at the time of UPS
installation.

A manual static bypass pushbutton is located on the FN front control panel. When the UPS is operating from
utility in the normal utility mode on-line state, depressing this button will cause the UPS to transfer to bypass.
Depressing the bypass button again will return the UPS to normal inverter operation.

Automatic Bypass Transfers

NOTE: Bypass power will only be available if the bypass input is connected at the time of UPS installation.

The FN Series UPS will automatically switch to bypass mode under the following conditions: To energize the
connected load when the UPS is first turned on; encounters an overload; encounters an over temperature
condition; or upon a UPS failure condition. Should any of these events occur, the UPS will transfer to bypass
mode, sound an audible alarm and provide a "BPS" indication on the LCD display.

Output Filter

As with the input filter stage, the output filter maintains conducted (EMC) and RFI levels below FCC Class A
limits.
