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” ACpowertoelectronic equipmentsuchas Computer
Systems, Point of Sale Terminals, Process Controls, Telecommunications, Cable
TV Headend, Broadband LAN, Manufacturing Control Systems, Critical Care and
Hospital Lab Equipment.
SURGE AND SPIKE REJECTION
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.
REGULATION
Unlike many standby power systems, which regulate output voltage
only when operating from their battery backup, the Alpha CFR UPS
constantly maintains+1% output regulation without using precious battery power.
Even with input voltage fluctuations as great as +10% or -25%, the output remains
constant, regardless of load.
ISOLATION
Electromagnetic and Radio Frequency Interference (EMI and RFI) can
damage semiconductors and have devastating effects on critical data. The CFR
UPS input is
totally isolated from the output to provide maximum protection 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.
EXTENDED BACKUP CAPABILITY
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.

COMMUNICATIONS AND INTELLIGENCE
Alpha'sinterchangeableStandard Interface DeviceandIntelligentInterface
Deviceallows your CFR tobecome an activepartofyourcommunications 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 AND OVERLOAD INFORMATION
The Alpha CFR provides vital load information to eliminate guess work
associatedwith matchingtheappropriate loadtoyour unit. TheAlphaCFRdisplays
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.
SAFETY
Designed to meet or exceed the safety standards established by UL,
CSA andVDE, the Alpha CFR UPS is one of the safest, most reliable and versatile
uninterruptible power supplies available. Our commitment to safety and quality

6.3 Battery Testing
To determine the maximum amount of battery run time available, run this
test at least once a year. The length of the test can vary from several minutes to
many hours and should not be done during critical applications. Since the test
discharges the batteries, backup power may not be readily available (for several
hours) in the event of a utility power failure.
1. Unplug the AC line cord from the wall receptacle. The front panel“LINE
FAILURE” LED will come ON. Make a note of the START time.
2. When the CFR reaches LOW BATTERYWARNING, record the time.
Subtract the START time to determine the actual safe run time. To cancel
the test, plug the AC line cord back into the wall receptacle.
3. To determine the reserve time available, allow the UPS to continue until it
reaches LOW BATTERY SHUTDOWN. WARNING: This will cause the
load to go down. Make a note of the time. Subtract the LOW BATTERY
WARNING time to determine your availablereserve time.
4. Switch the load OFF. Plug the AC line cord back into the wall receptacle.
The“LOW BATTERYWARNING”LED will remain ON until the batteries
are partially recharged. Switch the load ON, one device at a time. To
determine recharge time, subtract the time you resumed LINE PRESENT
operation from when the“LOW BATTERY WARNING” LED goes OFF.

2. FEATURES
2.5 Communication / Interface Options
The CFR is equipped with four rear panel jacks for communication and
remote interfaces: RS-232 Serial data; LAN Interface; External IID and External
Alarms. Units with the external modem option have a fifth connector for modem
connection.
NOTE: With the SID installed in the UPS, either the External IID port or the
RS-232port can beactivated. Thefactory default issetforRS-232operation.
With the internal IID option installed in the UPS
both ports are active.
RS-232Monitoring/ControlApplications
The Alpha CFR-UPS provides a standard RS-232 serial port on a DE-9
female connector. This port may be used to monitor and control the CFR using 1)
ASCII terminals, 2) an external modem, 3) UPS monitoring software and 4) SNMP
agent devices.
You may use the serial port to interface with a dumb terminal or a personal
computer (running a terminal emulation software) to monitor, control, and calibrate
the CFR. All you need is a standard off-the-shelf,“straight-through,”RS-232 cable
and a terminal. Refer to section 5 “RS-232 TERMINAL COMMUNICATION” for
more information. On a SID equipped unit, this port can connect to a customer
supplied,external modem(referto section“4.2External Modem Configuration”and
“4.3 External Modem Operation” for more information).
Youmay alsousethe RS-232serial port to communicate withtheintelligent
UPS monitoring software running on a host computer or a SNMP agent device
connected to your LAN network. Alpha Technologies provides the “AlphaNet C”
family of UPS monitoring software and SNMP agents to manage your network
requirements. You can use the“AlphaNet C shutdown software” tomonitorthe CFR
in a network environment and to perform an orderly system shutdown when the
battery becomes low (during extended line fail situations). AlphaNet C shutdown
software informs all workstations of pending power failures and shutdowns and in
multi-server networks, AlphaNet can shutdown other servers in the network as well
astheworkstations. For a full descriptionofthefeaturesandcapabilitiesof AlphaNet
C shutdown software, refer to its user’s manual or contact Alpha Technologies.
AlphaNet C is available for all major network platforms and operating systems —
Novell Netware, SCO Unix, IBM OS/2, IBM AIX, Sun Solaris, Hewlett-Packard HP-
UX (DAT), and Digital Equipment (OS/F,VMS, and DECNET).
AlphaTechnologies also provides the“AlphaNet CS SNMP Agent Device”
tomonitor andcontrolthe CFR usingtheSNMP protocol. Thisprovidesan interface
betweentheCFR and yournetworkenvironmentandallowsyou to useyourNetwork
Management Station (NMS) to monitor and control the CFR. To obtain detailed
information on SNMP management solutions for your CFR refer to

6.1 CFR Maintenance
The electronic components used in the UPS require no maintenance. If
the unit fails to perform a specific function, refer to the troubleshooting guide. The
guide lists typical symptoms, causes and solutions that apply to the UPS, starting
with the most obvious and working systematically through the unit.
Byestablishing a routinemaintenanceprogramand following theguidelines
contained in this manual, your Alpha CFR will continue to provide years of trouble-
free service.
6.2 Battery Maintenance
The maintenance free batteries used in the UPS will be affected by many
variables including operating temperatures, number of discharges over the life of
the battery, charging characteristics, and low voltage cell cutoff. The Alpha CFR
complies with all factory recommendations for charging and discharging batteries
to ensure optimum performance and the longest possible battery life.
Duringnormal operation,theUPS batterieswilltend to increasein capacity
over the first three to twelve months of service. There can be as much as a 20%
increase in available backup power after the first ten to fifteen battery discharges.
Once the batteries reach this peak, they will slowly begin to lose capacity until,
eventually, they will be unable to provide the required backup power.

EPO (Emergency Power OFF) Switch
(FactoryInstalled Option)
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.
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 in the building must be
switched OFF. Consult your national and local electrical codes for further
information.
