1. Safety
Save these instructions
This document 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 illustrations contained in
this document before proceeding. If there are any questions regarding the safe installation or operation of this
product, contact Alpha Technologies Ltd. or the nearest Cordex® power system 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 document. Where these symbols appear, use extra care and attention.
Symbol Type Description
Risk of serious injury or death
Equipment in operation poses a potential electrical
hazard which could result in serious injury or death to
personnel. This hazard may continue even when power is
disconnected.
Cautions indicate the potential for injury to personnel.
Risk of burns
A device in operation can reach temperature levels which
could cause burns.
The use of attention indicates specific regulatory or code
requirements that may aect the placement of equipment
or installation procedures. Follow the prescribed procedures
to avoid equipment damage or service interruption.
This symbol indicates the location or terminal intended for
the connection to protective earth. An enclosure that is not
properly connected to protective earth presents an electrical
hazard. Only a licensed electrician can connect AC power
and protective earth to the enclosure.
A notice provides additional information to help complete a
specific task or procedure or general information about the
product.

1.2 General warnings and cautions
You must read and understand the following warnings before installing the system and its component.
Failure to do so could result in personal injury or death.
• Read and follow all instructions included in this document.
• Only trained personnel are qualified to install or replace this equipment and its components.
• Use proper lifting techniques whenever handling equipment, parts, or batteries.

• 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.
• Always assume electrical connections or conductors are live. Turn o 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 o.
• At high ambient temperature conditions, the internal temperature can be hot so use caution when
touching the equipment.
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 installation or
removal procedure.
WARNING
This system is designed to be installed in a restricted access location that is inaccessible to the
general public.
Ce système est conçu pour être installé dans un endroit à accès restreint inaccessible au grand
public.
Before working with any live battery or power system, follow these precautions:
• Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces.
• Wear safety glasses with side shields at all times during the installation.
• Use Occupational Safety and Health Administration (OSHA®) approved insulated hand tools. Do
not rest tools on top of batteries.
1.3 Mechanical safety
1.4 Electrical safety
WARNING
Hazardous voltages are present at the input of power systems. The DC output from power
modules, though not dangerous in voltage, has a high short‑circuit current capacity that can
cause severe burns and electrical arcing.
The DC output from converters is a potentially hazardous voltage. Do not touch the output connections
when under power. Ensure that power has been removed from the outputs before working on them.
WARNING
This equipment is not suitable for use in locations where children are likely to be present.
Cet équipement ne convient pas pour une utilisation dans des lieux ou des enfants sont
susceptibles d’être présents.
• Keep hands and tools clear of fans. Fans are thermostatically controlled and switch on automatically.
• Power supplies can reach extreme temperatures under load.
• Use caution around sheet metal components and sharp edges.

1.5 Installation and safety precautions
• Only qualified personnel should install and connect the power components within the Cordex®power
system.
• Make sure to connect the protective earthing (master grounding) terminal within the AC load center
of the equipment to the earth point in the building installation or the site reference ground.
• Only install the power system using the mounting hardware provided by Alpha Technologies Ltd.
CAUTION
Follow all local safety practices and guidelines while lifting the enclosure. All personnel involved
with lifting and positioning the enclosure must wear head and eye protection, and gloves. Only
properly trained and certified personnel should operate the crane. Only properly trained and
certified personnel should operate the forklift.
1.6 Lifting
Before lifting the power system into place:
• Ensure the modules are not installed.
• The distribution panel door is firmly axed.
• Open and latch the enclosure front door.

2. Introduction
2.1 Document scope
This document covers the features, options, installation, and startup of Cordex® CXPS-HSS hyperboost converter
systems. Images contained in this document are for illustrative purposes only and may not exactly match your
installation. To assist with installation, refer to the drawings at the end of this document.
2.2 Product overview
The –48 Vdc to –58 Vdc Cordex® CXPS-HSS hyperboost converter system is a unidirectional boost converter
system designed to allow for larger loads to be powered while keeping the load current constant. By using a DC
power system as its input, the unidirectional boost converter boosts DC voltage as high as 58 volts at its output.
The system is based on the Cordex® HP –48 to –58 Vdc 3 kW hyperboost converter shelf and module and are
used to boost the DC voltage to reach the remote radio head (RRH) while leveraging existing power cable
infrastructure. The Cordex® CXPS-HSS hyperboost converter system can be deployed as a standalone system,
with an optional in-shelf controller or can be paired with Cordex® CXPS –48 Vdc power system for a tightly
integrated solution using our flagship Cordex®HP controller.
Each fan-cooled converter module can deliver up to 3,000 watts of nominal power up to 149°F (65°C) and
2,400watts of power up to 167°F (75°C).
Information, adjustments, and controls are a simple process with the Cordex® HP family of controllers.
Configuration, adjustments, and information monitoring of the power equipment are accessible through a
network web browser.
