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 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 document. Where these symbols appear, use extra care and attention.
1.2 General warning and cautions
• 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.
CAUTION
Cautions indicate the potential for injury to personnel.
CAUTION
Risk of burns
A device in operation can reach temperature levels which could cause burns.
WARNING
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.
WARNING
This system is designed to be installed in a restricted access location which is inaccessible to the
general public.
ATTENTION
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.
GROUNDING
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.
NOTICE
A notice provides additional information to help complete a specific task or procedure or general
information about the product.

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 OSHA approved insulated hand tools. Do not rest tools on top of batteries.
• 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 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 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.
1.3 Mechanical safety
• 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.
1.4 Electrical safety
WARNING
Hazardous voltages are present at the input of power systems. The DC output from rectifiers,
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
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.

CPH-144 Central Power Hub
2. Overview
The Central Power Hub (CPH) is based on an SE41-2722 enclosure with a Cordex® CXPS-E3 400A power
system and a Cordex® HP LPS36 shelf to provide ±190 Vdc line powering channels from an AC utility
source. To better communicate the function and application of the system, marketing material (user guide,
data sheet, and website) will refer to the SE41-2722 enclosure as the CPH-144.
The CPH-144 is a Type 3R outdoor central power hub enclosure providing up to 144 ±190 Vdc line powering
channels from an AC utility power source. The CPH-144 utilizes remote line powering equipment as a method of
energizing remote devices using power delivered from a central source over copper cable.
The CPH-144 is configured as follows:
• SE41-2722 enclosure with heat exchanger AC loadcenter with main breaker and TVSS.
• Cordex® CXPS-E3 400A power system with Cordex® HP 2.4/3.0 kW rectifier shelves.
• Cordex® HP LPS36 up-converter shelves.
• Cordex® CXC HP system controller.
• High-voltage 50-pair protector panel.
