Important Safety Instructions
Before using this equipment read all manuals and other documents related to this unit and other equipment
connected to this unit. Always have a copy of a units manual on file nearby, in a safe place; if a replacement
copy of a manual is needed it can be found at the www.lamarchemfg.com.
Electrical Safety
WARNING: Hazardous Voltages are present at the input of power systems. The output from
rectifiers and from batteries may be low in voltage, but can have a very high current capacity that
may cause severe or even fatal injury.
When working with any live battery or power system, follow these precautions:
Never work alone on any live power system, someone should always be close enough to come to your aid
Remove personal metal items such as rings, bracelets, necklaces, and watches.
Wear complete eye protection (with side shields) and clothing protection.
Always wear gloves and use insulated hand tools.
WARNING: Lethal Voltages are present within the power system. Parts inside the unit may still be
energized even when the unit has been disconnected from the AC input power. Check with a meter
before proceeding. Do not touch any uninsulated parts.
A licensed electrician should be used in the installation of any unit.
Always disconnect the unit from the supply, batteries and loads before performing maintenance or cleaning.
If the unit is hot-swappable, simply remove it from the shelf for any maintenance or cleaning.
Always assume that an electrical connection is live and check the connection relative to ground.
Be sure that neither liquids nor any wet material come in contact with any internal components.
Do not operate this unit outside the input and output ratings listed on the unit nameplate.
Do not use this unit for any purpose not described in the operation manual.
Mechanical Safety
This unit or parts of the unit may get very hot during normal operation, use care when working nearby.
Do not expose equipment to rain or snow. Always install in a clean, dry location.
Do not operate equipment if it has received a sharp blow, been dropped, or otherwise damaged in any way.
Do not disassemble this unit. Incorrect re-assembly may result in a risk of electric shock or fire.
Battery Safety
WARNING: Follow all of the battery manufacturer’s safety recommendations when working with or
around battery systems. DO NOT smoke or introduce a spark or open flame in the vicinity of a
battery. Some batteries generate explosive gases during normal battery operation.
To reduce risk of arc, connect and disconnect the battery only when the unit is off.
If it is necessary to remove battery connections, always remove the grounded terminal from the battery first.
Remove personal metal items such as rings, bracelets, necklaces, and watches.
Always wear rubber gloves, safety glasses, and a rubber lined vest/apron when working near a battery.
Have plenty of fresh water and soap nearby in case the battery electrolyte contacts skin, clothing, or eyes.
If the battery electrolyte contacts skin or clothing, wash immediately with soap and water.
If the electrolyte enters the eye, immediately flood the eye with running cold water for at least ten (10)
minutes and seek medical attention immediately.
Do not drop metal on a battery. A spark or short-circuit could occur and could cause an explosion.

ii
Unit Location
Allow at least 6 inches of free air on all vented surfaces for proper cooling
Allow sufficient clearance to open the front panel for servicing.
Do not operate this unit in a closed-in area or restrict ventilation in any way.
Do not set any battery on top of this unit.
Never allow battery electrolyte to drip on this unit when reading the specific gravity or filling the battery.
Never place this unit directly above a standard flooded battery. Gases from the battery will corrode and
damage equipment.
A sealed maintenance free or valve regulated lead acid (VRLA) battery may be placed below this equipment.

1 Overview
1.1 Introduction
The DCPS is a box-type power system that provides power for 48 V DC communications equipment. It uses 50
A rectifiers and provides a maximum output current of 200 A.
1.2 Model Number Description
DCPS stands for DC Power System
1.3 Features
The DCPS has the following features:
Wide voltage range of 85 V AC to 300 V AC
Comprehensive battery management
Network application over a fast Ethernet (FE) port and an RS485/RS232 port
Communication such as the Simple Network Management Protocol (SNMP) and
Hypertext Transfer Protocol Secure (HTTPS) to enable remote management and
unattended working.
Remote software upgrade.
Liquid crystal display (LCD) for display and operations
Web user interface (Web UI) for display and operations
Display in multiple optional languages
Hot swapping of rectifiers and the DCSC
Rectifier power factor up to 0.99
1.4 Work Principles
AC power enters rectifiers through the AC power distribution unit (DCD). The rectifiers convert the AC power
input into 48 V DC power output, which is directed by the DC DCD to DC loads along different routes.
When the AC power is normal, rectifiers power DC loads and charge batteries. When the AC power is absent,
rectifiers stop working and batteries start to power loads. After the AC power resumes, rectifiers power DC
loads and charge batteries again.
The DCSC monitors the operating status of each component in the power system in real time and performs
appropriate intelligent control. When detecting a fault, the DCSC generates an alarm.
