1�4 Electrical Safety
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.
WARNING!
The DC input to the modules (and the converter system) – though not dangerous in volt-
age – has a high short circuit current capacity that may cause severe burns and electri-
cal arcing.
The DC output is a potentially dangerous voltage. Do not touch the output connections
when under power. Ensure that power has been removed from the outputs before work-
ing on them.
NOTE:
RFT-V output circuit configuration – bridged operation (not permitted)
The DC output is classified as an RFT-V circuit with a maximum rated power of
100W per channel. Paralleling of RFT-V circuits over multiple telecommunications
wires for the purpose of delivering power in excess of 100VA to a single load circuit
is not permitted. Refer to UL/CSA 60950-1 Section 6.2.1 for details.
RFT-V output circuit configuration – normal operation (permitted)

0120011-J0 Rev M
WARNING!
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.
• Do not work alone under hazardous conditions.
• A licensed electrician is required to install permanently wired equipment. Hazardous voltages are present at
the input of power systems. 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 along with customer installed radios 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.

2� Product Overview
The LPS36 is a modular DC to DC up-converter system designed for distributed power communications applica-
tions using +/- 190Vdc (RFT-V circuit) over existing copper network.
Using switched mode technology, the LPS36 quad output converter module provides outstanding efficiency in a
compact design. Applications include powering sealed DSLAM’s, Distribution Point Units (DPU) as well as Optical
Network Terminals (ONT) in Fiber to the Home Networks (FTTH). Each LPS36 converter module contains four iso-
lated DC-DC converters, up to 100 Watt maximum. Converter modules are ordered separately at time of ordering or
later after the converter system has been installed. Blank plates can be ordered separately for empty slots.
• High efficiency >92% for increased operating expenses (OPEX) savings and reduced carbon footprint
• High temperature tolerance for installation in Central Office (CO) or harsh outside plant (OSP) cabinet environ-
ments
• Industry leading power density enabling up to 48 channels in a compact 2RU footprint
• High reliability convection-cooled design with optional fan tray
• Cordex CXCI series of system controllers provide advanced remote web based monitoring and control features

0120011-J0 Rev M
The 19" and 23"LPS36 systems consist of one or more converter modules and a CXCI+ controller installed in a
common shelf. A 19" shelf can have up to 9 modules, and a 23" shelf up to 12. All connections are front access. In-
put connections can be made at the rear of the unit as well. External connections are available at the shelf interface
panel for alarm interfaces.
The LPS36 Compact packs maximum power into minimum space, but doesn’t compromise on features. The shelf
provides up to 16 line powering channels in the compact 2RU x 6” x 12” form. Standard system features include
major and minor alarms for monitoring, connectorized cable output and one side mounting. This product is particu-
larly suitable for remote OSP power cabinets where free rack space is tight or non-existent. With a six inch width
and a single side bracket, it can be easily mounted to the side of a rack support post without using up valuable rack
space.
Alpha’s LPS36 modular DC to DC converter systems incorporate a full range of standard features, including cur-
rent limiting and individual ground fault interrupt for each circuit. Particular emphasis is placed on recognizing a
fault condition and shutting down the circuit as quickly as possible to ensure the highest level of personnel safety.
Compliance with GR-1089-CORE - Class A2 provides the ability to work on the equipment while powered, which
significantly reduces the administrative and labeling requirements and overheads for the high voltage wiring.

4� Features
4�1 Converter Modules
A module contains four isolated DC to DC converters with a common control and supervisory circuit. Each module
output operates independently. An internal micro controller monitors both the inputs and outputs of the converters,
turns the converters on and off, and generates a converter fail alarm if required.
4�1�1 Status Indicators
The converter module has four LED indicators – one per converter. The LEDs are color-coded to indicate converter
status as follows:

Two converter fail outputs are present at the card edge connector. Alarms are activated after a one second delay for
the following conditions:
• Internal regulation fails
• Output voltage <±140V
• Over Voltage Protection (OVP) operation
• Ground Fault Interrupt (GFI) trip
• Input fuse or output fuse fail
• Output short circuit (±30V ± 20%)
•Input voltage out of range

4� 2 �1 Controllers
Both the CXCI HP and the CXCI+ controllers (Figure 4 and Figure 5) can be used in the shelves. For details on
using either controller go to the Alpha website to download the relevant software manual.
CXCI HP
CXCI HP in-shelf controllers have a small organic LED (OLED) display. This displays 30 characters total (six char-
acters wide, five lines high) and the controller has three navigation buttons and one reset button. The display has
three main operating modes: dashboard, menu and screen saver.
After 20 minutes with no activity, the controller goes into screen saver mode and the display shuts off. From
screen saver mode, press any of the three navigation buttons to re-activate the screen and enter dashboard
mode.

LEDs
Each controller has three LEDs located on the front panel. These are used to display the alarm status of the power
system, controller progress and status during startup, as well as file transfers.
Alarm Conditions
The controller illuminates the LED that corresponds to the system alarm status. Only one LED is illuminated at a time
during alarm conditions. The following show the corresponding alarm status for each LED color:
Green:OK, no alarms
Yellow:Minor alarm, no major alarms
Red:Major alarm
Progress and Status Indication
The LEDs are also used in the following situations:
• Base unit validation – all three LEDs are on at the same time.
• File transfer – when recovering from invalid firmware application – the red LED is illuminated.
Reset
Refer to Section "Controller Reset" on page 53 for reset options.

4�2�3 Alarm Relays (Form C Contacts)
The converter shelf has an interface panel with terminal blocks for Major and Minor alarm outputs (Form C contacts),
which are controlled by the controller. The Major alarm relay is designed to “fail safe” to ensure the alarm is regis-
tered when power is removed

OFF: Ok, no alarms
Red: Major alarm
Yellow: Minor alarm
Major Alarm
The Major alarm relay de-energizes under any one of the following conditions:
• When two or more outputs have failed within a shelf
• When the DC input feed is below the normal operating voltage
• When the DC input feed is above the normal operating voltage
Minor Alarm
The Minor alarm relay is de-energized under any one of the following conditions:
• Single output has failed within a shelf
• Internal ambient temperature is out of range
Alarm LEDs
On the front of the interface panel, are two LEDs—one red and one yellow, which indicate the shelf alarm status
(Figure 7).
If a Major alarm is activated, it "resets" the Minor
alarm relay to an energized state.
