NOTICE:
The CFR 7.5K, 10K and 15 K generates, uses and can radiate radio frequencies if not installed and
tested in accordance with the instructions contained in this manual. It has been tested and found to
comply with the limits established for a Class A computing device pursuant to part 15 of FCC rules
when it is operated alone. It also complies with the radio interference regulations of DOC which are
designed to provide reasonable protection against such interference when this type of equipment is
used in a commercial environment. If there is interference to radio or TV reception, which is deter-
mined by switching it on and off, relocate the equipment or use an electrical circuit other than the
one used by the CFR 7.5K, 10K and 15 K.

Introduction
This section introduces you to the Alpha
7.5K, 10K and 15K CFR UPS’s:
• The CFR advantage (Section 1.1).
• An tour of the unit, it’s connectors, switches and
control panels (Section 1.2).

1.1 The CFR Advantage
!Advanced Power Protection Technology
Alpha’sCFR UninterruptiblePower Supply(UPS)provides continuousand conditioned
computer-gradeACpowerfor computersystems, point ofsale terminals, processcontrols,
telecommunications,cable TVheadend,broadbandLAN,manufacturingcontrolsystems,
hospitalcritical care andlab equipment.
!Regulation
Theunitmaintains±1%output regulationwithout usingthebatteries.Evenwith inputvoltage
fluctuationsas great as+10% or –20%,the output isconstant regardless ofthe load’s size.
!Isolation
Theoutput istotallyisolated fromthe input toprotect theloadsfrom spikes,surges and line
noise.The ferroresonant transformer providesnon-degradable spikeand surge protection.
!ExtendedBackupCapability
Alpha'sEBP Series externalbattery packs extendsbackuptime duringpoweroutages.
Installingthe battery packis as simpleas plugging itin.
!Self Test Function
Thebuilt-in selftestchecks allcritical areas,includingthe batteries,to ensureoptimumper-
formance.
!Load and Overload Information
Thedisplay panelsshows theloading andtells youwhen theunit isoverloaded.
!Generator Ready
