bols have been placed throughout this manual. Where these symbols appear, use extra care and attention.
The use of ATTENTION indicates specic regulatory/code requirements that may a󰀨ect the
placement of equipment and/or installation procedures.
WARNING!
WARNING presents safety information to PREVENT INJURY OR DEATH to personnel.
Warnings are indicated by a shock hazard icon, the word WARNING, and a rule beneath
which the information appears.
WARNING!
You must read and understand the following warnings before installing the enclosure
and its component. Failure to do so could result in personal injury or death.
CAUTION!

1.3 Electrical Safety
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.
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
240 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.

2. Product Overview
2.1 Scope of the Manual
This instruction manual explains the installation and interconnection of Alpha Technologies’ LPR12-150-IP68 and
LPR48-150-IP68 converter system. To aid with installation, frequent reference is made to the drawings located at the
rear of the manual.
2.2 Introduction
The LPRxx-150-IP68 is a compact, sealed, standalone, RFT-V line powering down-converter unit designed for
remote site powering applications using +/- 190Vdc (RFT-V circuit) over twisted copper pairs. The LPRxx-150-IP68
provides a bulk regulated nominal 12 or -48Vdc output from two twisted copper pairs, with maximum power of
150W.
Line Powering Network (a.k.a. Express, Simplex, Remote, Centralized) is a method of distributing energy over an
existing copper network. Multiple twisted-pair copper is used to distribute 100VA limited power sources at ±190Vdc.
The individual, isolated inputs are terminated at a remote end and converted back to a bulk 12Vdc or 48Vdc supply.
Power holdup capabilities are incorporated into the LPRxx-150-IP68 to provide at least 150 millisecond of backup for
a 100 W load. The holdup prevents potential lengthy customer communication outages due to remote node reset-
ting caused by line surges and ensure maximum reliability.
See the Features section for more information. The Specifications Section of this manual, details the electrical rat-
ings.
2.3 Part Number
This product is available to order under the following part numbers:
LPR12-150-IP68 0370421-001
LPR48-150-IP68 0370414-001

2.4 Product Features
Output Power
Each of the two isolated converters on each LPRxx-150-IP68 module has a maximum output capacity of 75W (for a
total capacity of 150W per module). The power output is a function of the input voltage into each converter. Proper
network engineering and copper pair sizing is a requirement for meeting the power demand of the load.
Current Limit
The current limiting function provides a primary response to output overload situations.
Input Low Voltage Protection
The converter module is electronically protected from low voltages at the inputs by fault detection circuitry. If the
input to the converter module falls below the lower DC input limit (see Specifications), the module will shut down.
Reverse Polarity Protection
The converter design has incorporated reverse polarity protection from the connection to a power source on the
input. This prevents damage to the converter circuitry if a reverse connection is made.
Module Alarm Relay
The module alarm relay (Form C dry contact) is deenergized (i.e., NO to Com is open) if any or both of the two chan-
nel outputs fail.

At the time of installation, carry out a system assessment to ensure that the effective capacitance of the total system,
including the capacitance from the output of the up-converter (front-end), does not exceed 11μF (Line to Earth) and
40μF (Line to Line).
4.2 RFT-V Circuits
At the time of installation, ensure that the voltage rating of the wiring of the telecommunication network is adequate
for thenormal RFT circuit voltage (+/-200Vdc), together with superimposed transients.
Ensure that the circuits to be connected together are all RFT-V circuits.
