1.2 The CFR Advantage
ADVANCED POWER PROTECTION TECHNOLOGY
Power protection devices can be judged b y the type and quality of power
they provide. Alpha CFR Uninterr uptible Power Supplies provide continuous,
conditioned “computer-grade” AC power to electronic equipment such as 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
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.
totally isolated
from the output to provide maximum protection from
EXTENDED BACKUP CAPABILITY
Alpha's EBP Series External Batter y Packs allow you to greatly extend
your backup capabilities and power through long utility outages. Completely selfcontained 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,

null-modem serial cable, DE-9 male to DB-25 male, is required to connect the
external modem to CFR. The most common ways to connect are by using one of
the following cable/adapter sets:
1. A null-modem cable with DE-9 male to DB-25 male ends (shown below).
2. A null-modem cable with DB-25 male to DB-25 male ends and a 9-25 adapter.
3 . A standard “straight-through” cable with DE-9 male to DB-25 female and a null-
modem adapter which has the TX and RX swapped in the adapter .
These cables and adapters are a v ailable commercially. Fig. 10 sho ws the
minimum set of connections required for making a null-modem cable. See Section
“4.2 External Modem Configuration” to configure the modem and CFR.

3. INSTALLATION
3.1 Pre-Installation
Do not connect the CFR UPS to a line conditioner, isolation transformer or
any other similar type of device. Damage to the CFR UPS and the line
conditioning equipment can occur.
Site Preparation
The UPS should be installed upright in a well-ventilated, dust free
environment. The weight of the UPS, especially if it has an optional battery pack,
is quite heavy (see specifications). Do not place the unit on any surface unable to
fully support its weight.
Utility Circuit Breaker
The UPS should be installed on a dedicated circuit with a properly sized
circuit breaker. Breaker size can be determined by adding 15% to the maximum
input current of the unit (see specifications). For example, the CFR 1500 draws
11.9 Amps of current when configured at 120VAC. By adding 15%, the number
becomes 13.7 Amps. In this case, a standard 15 Amp circuit breaker is suitable
for use.
Grounding
Since the CFR UPS bonds output neutral to ground (qualifying it as a
"separately-derived power source"), proper grounding is critical. Many older facilities
may have an electrical system that is incapab le of supporting this type of grounding
requirement. To ensure optimum performance from your UPS, always install a
hardwired ground. A qualified electrician should also inspect the existing wiring in
the building prior to installation to verify proper grounding.
Standby Generators
The CFR is equipped with a frequency sense circuit, along with a constant
slew frequency synchronization circuit, to optimize operation with most standby
generators. Prior to installation, compare the output voltage of the generator to the
voltage requirements of the UPS (see CFR nameplate label). If the UPS requires
240 V AC input and the generator produces only 208 V A C , it will cause the UPS to
run continuously off of battery power . This w ould discharge the UPS batteries and
cause the output to fail.
Alpha Technologies recommends using a generator equipped with an
electronic speed and voltage control. If a generator equipped with a mechanical
governor "speed control" is used, this could also cause the UPS to run continuously
in LINE FAILURE mode due to the unstable frequency of the generator.

3. INSTALLATION
3.2 Connecting the CFR (Plug and receptacle)
CAUTION: Installation and wiring should be performed by qualified service
personnel in accordance with applicable electrical codes. Ver ify that the
main utility panel is switched off before proceeding. Mark all circuit breakers
supplying the UPS.
1. Connect a dedicated ground wire from the GROUND lug on the back of the CFR
to an electrical ground point (i.e., wall receptacle gound or a copper water pipe).
The wire size must be at least 14 AWG (2.0 mm
and have green insulation provided with one or more yellow stripes.
NOTE: Most electrical codes require this type of ground connection in
case the AC Line power cord is disconnected from the wall. Always consult
your local electrical code to ensure prescribed grounding practices.
2. Connect the CFR’s A C power cord to the receptacle.
3. If using an external battery pack, plug its connector into the rear panel of the
UPS (see section 3.3).
NOTE: ALL rack mount units require an external battery pack. Before
attempting to operate these units without a battery pack, contact Alpha
T echnologies f or additional inf o rmation.
4. Start and test the UPS without the load connected (see section 4.1). After
testing, switch the unit OFF before connecting the load.
