1. INTRODUCTION
1.1 The Alpha CFR
Congratulations on your purchase of one of the most advanced and
intelligent Controlled Ferro Resonant-Uninterruptible Power Supply (CFRUPS) in the world! The Alpha CFR is designed to keep your equipment
operating, regardless of the condition of your utility power. This means that
your vital equipment will no longer be affected by spikes, surges, sags, noise,
brownouts, blackouts or other forms of electrical disturbances. Operation is as
simple as plugging your equipment into the back of the UPS and switching on
the power.
The CFR provides you with a wide range of power management options
using your choice of interface devices. The Standard Interface Device
displays vital UPS operating parameters, including Alarms, and allows you to
manually self-test the UPS. The Intelligent Interface Device provides you with
precise Voltage, Current and Frequency information, plus maintains an ongoing record of all Alarm and Line Failure Events. As an active center of
communication, your CFR can also be interfaced directly to your computer
system to inform you, and your users, of changes in status as they occur.
With distribution networks and service centers located throughout the
world, Alpha Technologies is here to back you up. From your date of
purchase, Alpha provides complete technical support and prompt, reliable
service to ensure that your CFR-UPS provides you with a lifetime of reliable
operation.
The Alpha CFR-UPS
provides regulated, current-limited,
output with excellent isolation and noise attenuation

1. INTRODUCTION
1.2 The CFR Advantage
ADVANCED POWER PROTECTION TECHNOLOGY
Power protection devices can be judged by the type and quality of
power they provide. Alpha CFR Uninterruptible Power Supplies provide
continuous, conditioned “computer-grade” AC power to electronic equipment
such as Computer Systems, Point of Sale Terminals, Process Controls,
Telecommunications, CATV Headend, Broadband LAN, Manufacturing
Control Systems, Critical Care and Hospital Lab Equipment.
Alpha's proven design virtually eliminates surges and spikes. The
Alpha CFR UPS provides spike attenuation of 2000 to 1 and meets the
requirements of IEEE 587 / ANSI 62.41.
Unlike many standby power systems, which regulate output voltage
only when operating from their battery backup, the Alpha CFR UPS
constantly maintains
power. Even with input voltage fluctuations as great as +10% or -25%, the
output remains constant, regardless of load.
Electromagnetic and Radio Frequency Interference (EMI and RFI) can
damage semiconductors and have devastating effects on critical data. The
CFR UPS input is
tection from this type of interference. Measured in decibels (dB) of attenuation, Alpha's CFR achieves up to 120 dB common mode, and 60 dB normal
mode.

Alpha's EBP Series External Battery Packs allow you to greatly extend
your backup capabilities and power through long utility outages. Completely
self-contained and pre-wired, simply plug the EBP cabinet into your CFR and
forget about it. EBP Series External Battery Packs can also be ordered with
an optional, external charger to greatly reduce battery recharge times.
EXTENDED BACKUP CAPABILITY

1. INTRODUCTION
1.2 The CFR Advantage,
COMMUNICATIONS AND INTELLIGENCE
Alpha's interchangeable Standard Interface Device and Intelligent
Interface Device allows your CFR to become an active part of your
communications network providing you with a variety of interface options.
SELF-TEST CAPABILITIES
The CFR has a built-in, self-test function that checks all critical areas of
the UPS, including the batteries, to ensure optimum performance. Whenever a problem is detected, the UPS lights a “Service” indicator. Self-test is
extremely useful during troubleshooting and maintenance.
PRECISE LOAD & OVERLOAD INFORMATION
The Alpha CFR provides vital load information to eliminate guess work
associated with matching the appropriate load to your unit. The Alpha CFR
displays the existing load, and whenever the load exceeds the rated output,
an "Overload" indicator is illuminated.
GENERATOR READY
The CFR UPS is equipped with a frequency sense circuit, along with a
constant slew frequency synchronization circuit, to provide trouble-free
operation with most standby generators.
Designed to meet or exceed the safety standards established by UL,
CSA and VDE, the Alpha CFR UPS is one of the safest, most reliable and
versatile uninterruptible power supplies available. Our commitment to safety
and quality engineering has not only established industry-wide safety
standards, but has earned Alpha Technologies international recognition as a
leader in power protection equipment.

EPO (Emergency Power OFF) Switch
(Factory Installed Option on
the CFR 1000 Only)
Pins 7 and 8 of the ALARM INTERFACE connector provide
EMERGENCY POWER OFF contacts. A switch contact can be hard-wired
to the UPS to completely shut down the system in the event of an
emergency, such as a fire.
In an emergency, the switch must be depressed (shorted) for at least
1.5 seconds. The UPS will shut down approximately 2 seconds after the
signal is recognized. The switch, connected to pins 7 and 8, must be
electrically isolated (up to 1500VAC isolation is recommended).
A system shut down in this manner will open the BATTERY circuit
breaker. In the event there is an actual fire in the equipment room, the wire
will melt causing as short circuit between pins 7 and 8 and open the
BATTERY circuit breaker.
CAUTION: When the EPO switch is activated, the AC LINE connected to
the UPS input may still be energized. To completely remove the power from
the building, the MAIN AC LINE breaker must be switched OFF. Consult
your national and local electrical codes for further information.
