1.3 Electrical Safety
WARNING!
WARNING!
Before working with any live battery or power system, follow these precautions:
a. Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
b. Wear safety glasses with side shields at all times during the installation.
c. Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
Lethal voltages are present within the power system. Always assume that an electrical
connection or conductor is energized. Check the circuit with a voltmeter with respect to
the grounded portion of the enclosure (both AC and DC) before performing any installa-
tion or removal procedure.
Follow battery manufacturer’s safety recommendations when working around battery
systems. Do not smoke or introduce an open ame when batteries (especially vented
batteries) are charging. When charging, batteries vent hydrogen gas, which can explode.
WARNING!
Hazardous voltages are present at the input of power systems. The DC output from rec-
tiers and batteries, though not dangerous in voltage, has a high short-circuit current
capacity that may cause severe burns and electrical arcing.
• Do not work alone under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment. Input voltages can range up to
480 Vac. Ensure that the utility power is disconnected and locked out before performing any installation or
removal procedure.
• Ensure that no liquids or wet clothes come into contact with internal components.
• Hazardous electrically live parts inside this unit are energized from the batteries even when the AC input
power is disconnected.
• The enclosure which contains the DC or AC power system must remain locked at all times, except when
authorized service personnel are present.
• Always assume electrical connections or conductors are live. Turn off all circuit breakers and double-check
with a voltmeter before performing installation or maintenance.
• Place a warning label on the utility panel to warn emergency personnel that a reserve battery source is pres-
ent which will power the loads in a power outage condition or if the AC disconnect breaker is turned off.
• At high ambient temperature conditions, the internal temperature can be hot so use caution when touching
the equipment.
1.4 Battery Safety
• Never transport an enclosure with batteries installed. Batteries must ONLY be installed after the enclosure has
been securely set in place at its permanent installation location. Transporting the unit with batteries installed may
cause a short circuit, fire, explosion, and/or damage to the battery pack, enclosure and installed equipment.
• Servicing and connection of batteries must be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
• Batteries contain or emit chemicals known to cause cancer and birth defects or other reproductive harm.
Battery post terminals and related accessories contain lead and lead compounds. Wash your hands after
handling batteries.
• Batteries are hazardous to the environment and should be disposed at a recycling facility. Consult the battery
manufacturer for recommended local authorized recyclers.

2. Introduction
The Alpha Technologies CXPS-FR3 is a standalone rectifier bay that can be used to upgrade inefficient and aging
Ferroresonant rectifiers. As a drop-in replacement for RL400 and PECO II 400 rectifiers, the FR3 repurposes existing
AC and DC cabling which minimizes installation time and avoids costly replacements.
For decades, Ferroresonant rectifiers have powered traditional telecom central offices. However, as Ferros age and
begin to fail, it is becoming difficult to find parts as well as qualified technicians to diagnose and repair the problems.
These maintenance issues can result in lower network reliability. These issues, coupled with the Ferros’ relative
operational inefficiencies, are driving operators to upgrade their systems to modern, high efficiency switch mode
rectifiers.
Alpha provides the ideal ‘like for like’ retrofit solution, with minimal installation time and disruption to the office. The
interfaces to the FR3 have been engineered in such a fashion that the existing AC and DC infrastructure feeding the
Ferroresonant plants can be reused. The building block for the FR3 is Alpha’s highly reliable Cordex HP 12.0kW and
4.0kW rectifiers.
Unlike other solutions in the market, the FR3 design enables operators to
add up to 50% more power capacity or recover floor space savings. In
addition, the wrap-around bay design deflects heat flow upwards, allow-
ing operators to install batteries directly behind the bay.
The bay also comes equipped with Alpha's powerful CXC HP controller,
which can further modernize the power plant with advanced control and
monitoring features. The built-in web server provides the user alternate
setup via local or remote IP access. The integrated logging feature allows
the capture of data from multiple inputs for AC/DC voltages, load/battery
current, and cell voltage/temperature. Features such as ‘Power Save’
help improve overall system efficiency by reducing operational losses.
• Ferroresonant rectifier retrofit solution for RL400 and PECO II 400
rectifiers
• Significant CAPEX savings by maintaining existing AC and DC ca-
bling infrastructure
• Unique solution providing up to 50% capacity growth or floor space
savings without changes to existing infrastructure
• Fully integrated solution including in-bay system controller
• Wrap-around bay design directs heat exhaust via the top, allowing
batteries to be placed directly behind the bay

Refer to section 7 for further wiring details.
4.5 CXC HP
The Cordex™ HP (CXC HP) controller provides centralized setup, control and monitoring of power systems. This
ranges from simple monitoring and threshold alarms for temperature, voltage and current, to advanced battery
charging and diagnostic features.
The controller supports dual Ethernet ports and a 4.3” LCD screen to allow simultaneous network, LCD and local
laptop access to the controller including both web and SNMP interfaces.
The CXC HP supports dual CAN ports to allow up to 256 power and/or ADIO modules to be controlled and moni-
tored. The controller uses external analog and digital input and output (ADIO) peripherals to monitor electrical signals
(temperature, voltage, current) and generate electrical signals through relays.
The most commonly used ADIO peripheral is the L-ADIO for low voltage systems which includes:
• 8 digital inputs
• 4 voltage sensors
• 4 temperature sensors
• 4 current sensors
• 12 Form C relay outputs

USB flash drive.
• CAN: dual independent CAN bus ports for communication with the Alpha Cordex and AMPS family of products,
which allows for a greater number of devices.
• Real-time clock with field replaceable lithium battery: allows for timestamps on alarms and events.
• System fail alarm/relay: which activates when there is a major internal failure. During such a condition the unit at-
tempts to reset.
4.6 L-ADIO
The L-ADIO is the standard analog and digital I/O peripheral for low voltage (<60Vdc) systems. The L-ADIO communi-
cates on CAN bus to the controller and provides user access to I/O management via the CXC HP controller.

4.6.1 Analog Inputs
Four voltage inputs, V1 – V4, are provided for a variety of voltage monitoring requirements. The input channels can
measure a signal between -60Vdc to +60Vdc.
Four current input channels, I1 – I4, provide monitoring of current; e.g., discharge (load) and charge (battery). The
CXC HP is capable of monitoring standard shunts of 25, 50 and 100mV as well as application specifications of up to
250mV. The shunt current rating can be configured via the controller and is set by default to 800A 25mV. The input
range for this signal is -250mV to +250mV.
Four temperature input channels, T1 – T4, provide monitoring of temperature probes (thermistors). These are typi-
cally used for either ambient temperature, or for battery post monitoring to enable battery temperature compensa-
tion. The temperature sensor is provided by Alpha in various lengths. The input range for this signal is 0V to 5V and
is powered internally from the L-ADIO.
Digital Inputs
The L-ADIO can accommodate up to eight digital input channels, D1 – D8. Each channel responds to a zero or sys-
tem voltage potential at the input to activate or deactivate the appropriate condition.
These channels can monitor digital alarm/control signals from rectifiers, converters and many other types of equip-
ment.
An additional digital input, “EXT” is reserved for monitoring an external LVD override.
Alarm and Control Output Relays
Each L-ADIO contains twelve Form C alarm output relays to extend alarms and to control external apparatus. Each
internally generated alarm or control signal may be mapped to any one of the 12 relays, several signals may be
mapped to just one relay or none at all.
LED Indication
Each L-ADIO contains three LEDs for peripheral status indication.
LVD – Yellow = LVD Override Engaged
Power – Blue = Power present to device
Comms – Green = L-ADIO has been acquired by CXC HP
Front Panel Reset Button
A reset button is located on the front panel. It takes approximately 15 seconds before the unit is reacquired after
pressing the reset button.
During a reset condition, the L-ADIO will keep relays in their last known state to prevent false alarm notifications and
possible changing system LVD states.
CAUTION – Pressing the reset button will cause the L-ADIO to lose communication with the controller.

4.6.2 6I-ADIO (Optional)
The 6I-ADIO is an analog input peripheral providing six isolated shunt inputs. The 6I-ADIO communicates on CAN
bus to the CXC HP controller and provides access to shunt inputs via the controller.
