1� Safety
SAVE THESE INSTRUCTIONS: This manual contains important safety instructions that must be followed during
the installation, servicing, and maintenance of the product. Keep it in a safe place. Review the drawings and il-
lustrations contained in this manual before proceeding. If there are any questions regarding the safe installation or
operation of this product, contact Alpha Technologies or the nearest Alpha representative.
1�1 Safety Symbols
To reduce the risk of injury or death, and to ensure the continued safe operation of this product, the following
symbols have been placed throughout this manual. Where these symbols appear, use extra care and attention.
NOTE:
A NOTE provides additional information to help complete a specic task or procedure.
Notes are designated with a checkmark, the word NOTE, and a rule beneath which the
information appears
CAUTION!
CAUTION indicates safety information intended to PREVENT DAMAGE to material or
equipment. Cautions are designated with a yellow warning triangle, the word CAUTION,
and a rule beneath which the information appears.
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.
HOT!
The use of HOT presents safety information to PREVENT BURNS to the technician or
user.
1�2 General Warning and Cautions
WARNING!
This system is designed to be installed in a restricted access location that is inacces-
sible to the general public.
1�3 Mechanical Safety
CAUTION!
Do not disassemble the product – call our qualied service centers for servicing. Incor-
rect reassembling may result in a risk of electrical shock or re.
Do not operate the product if it has received a sharp blow, it has been dropped, or oth-
erwise damaged in any way – return it to a qualied service center for repair.

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!
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 pres-
ent 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
present 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 touch-
ing the equipment.
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.

2� Product Overview
2�1 Introduction
The 100VA eLimiter+ is a unique remote powering solution that meets the NEC requirements for remote power-
ing of electrical devices such as iDAS (indoor distributed antenna systems), remote radios, security cameras,
different sensors, access controllers and alarms. The unit can be used to distribute -48Vdc to remote equipment
without the use of conduits and complies with the NEC requirement for Class 2 power limited circuits.
Power circuits can be combined with fiber optic cables in cost effective easy-to-install composite cables.
The eLimiter+ reduces capital expenditure costs for deployment and simplifies installation of equipment that requires
remote powering such as distributed antenna systems equipment.
2�2 Features and Benefits
• High efficiency >92% for increased operating expenses savings and reduced carbon footprint
• High temperature tolerance for installation in central office or harsh outside plant cabinet environment
• Industry leading power density enabling up to 36 channels in a compact 2RU footprint
• High reliability convection-cooled design with optional fan tray
• Cordex CXCI+ system controller provides advanced remote web based monitoring and control features
The eLimiter+ system consists of one or more converter modules and a CXCI+ controller installed in a common shelf.
The 19" shelf can have up to nine modules. Each converter module contains four isolated DC-DC converters, up to
100 Watt maximum. Input connections can be made at the rear of the unit as well as the front. External connections
are available at the shelf interface panel for alarm interfaces.
Converter modules are purchased separately at time of ordering or later once the converter system has been in-
stalled. Blanks can be ordered separately for empty slots.
