Important Safety Instructions
Before sing this eq ipment, read all man als and other doc ments related to this nit and other eq ipment
connected to this nit. Always have a copy of the nit’s man al on file nearby in a safe place; if a replacement
copy of a man al is needed, it can be fo nd at www.lamarchemfg.com.
Electrical Safety
WARNING Hazardo s Voltages are present at the inp t of power systems. The o tp t from rectifiers
and from batteries may be low in voltage, b t can have a very high c rrent capacity that may ca se
severe or even fatal inj ry.
When working with any live battery or power system, follow these preca tions:
•Never work alone on any live power system, someone sho ld always be close eno gh to come to yo r aid
•Remove personal metal items s ch as rings, bracelets, necklaces, and watches.
•Wear complete eye protection (with side shields) and clothing protection.
•Always wear gloves and se ins lated hand tools.
WARNING Lethal Voltages are present within the power system. Parts inside the nit may still be
energized even when the nit has been disconnected from the AC inp t power. Check with a meter
before proceeding. Do not to ch any nins lated parts.
•A licensed electrician sho ld be sed in the installation of any nit.
•Always disconnect the nit from the s pply, batteries, and loads before performing maintenance or cleaning.
•If the nit is hot-swappable, simply remove it from the shelf for any maintenance or cleaning.
•Always ass me that an electrical connection is live and check the connection relative to gro nd.
•Be s re that neither liq ids nor any wet material come in contact with any internal components.
•Do not operate this nit o tside the inp t and o tp t ratings listed on the nit nameplate.
•Do not se this nit for any p rpose not described in the operation man al.
Mechanical Safety
•This nit or parts of the nit may get very hot d ring normal operation, se care when working nearby.
•Do not expose eq ipment to rain or snow. Always install in a clean, dry location.
•Do not operate eq ipment if it has received a sharp blow, been dropped, or otherwise damaged in any way.
•Do not disassemble this nit. Incorrect re-assembly may res lt in a risk of electric shock or fire.
Battery Safety
WARNING Follow all of the battery man fact rer’s safety recommendations when working with or
aro nd battery systems. DO NOT smoke or introd ce a spark or open flame in the vicinity of a battery.
Some batteries generate explosive gases d ring normal battery operation.
•To red ce risk of arc, connect and disconnect the battery only when the nit is off.
•If it is necessary to remove battery connections, always remove the gro nded terminal from the battery first.
•Remove personal metal items s ch as rings, bracelets, necklaces, and watches.
•Always wear r bber gloves, safety glasses, and a r bber 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 r nning cold water for at least ten (10) min tes
and seek medical attention immediately.
•Do not drop metal on a battery. A spark or short-circ it co ld occ r and co ld ca se an explosion.

ii
Unit Location
•Allow at least 6 inches of free air on all vented s rfaces for proper cooling
•Allow s fficient clearance to open the front panel for servicing.
•Do not operate this nit in a closed-in area or restrict ventilation in any way.
•Do not set any battery on top of this nit.
•Never allow battery electrolyte to drip on this nit when reading the specific gravity or filling the battery.
•Never place this nit directly above a standard flooded battery. Gases from the battery will corrode and damage
eq ipment.
•A sealed maintenance free or valve reg lated lead acid (VRLA) battery may be placed below this eq ipment.
Check for Damages
Prior to npacking the prod ct, note any damage to the shipping container and take pict res. Unpack the prod ct
and inspect the exterior and interior of prod ct for damage. If any damage is observed, take pict res and contact
the carrier immediately to file a damage claim. Contact La Marche for a Ret rn Material A thorization n mber to
have the nit sent back for eval ation and repair.
CAUTION Fail re to properly file a claim for shipping damages, or provide a copy of the claim to La
Marche, may void warranty service for any physical damages reported for repair.
Returns for Service
Save the original shipping container. If the prod ct needs to be ret rned for service, it sho ld be packaged in its
original shipping container. If the original container is damaged/ navailable, make s re the prod ct is packed
with at least three inches of shock-absorbing material to prevent shipping damage. La Marche is not responsible
for damage ca sed by improper packaging of ret rned prod cts.
Inspection Checklist
 Enclos re exterior and interior is not marred or dented.
 There are no visible damage components.
 All internal components are sec re.
 Printed circ it boards are firmly seated.
 All hardware and connections are tight.
 All wire terminations are sec re.
 All items on packing list have been incl ded.
Handling
Eq ipment can be very heavy with neven distrib tion of weight. Use adeq ate manpower or eq ipment for
handling. Until the eq ipment is sec rely mo nted, care m st be sed to prevent eq ipment from being accidently
tipped over or dropped.

1 Overview
1.1 Introduction
The La Marche DCPS system tilizes high efficiency rectifiers, a highly intelligent system controller, I/O interface
board for alarms/ sensors, and a load/battery distrib tion panel. This complete DC system offers battery
management with low voltage disconnect, remote monitoring, remote config ration and config rable alarm
contacts.
The compact design of the system red ces space req irements and installation cost. The system is config red
with 48V/50A high efficiency rectifiers to provide a rated o tp t c rrent p to 200A. The DC distrib tion section
is comprised of 16 pl ggable load breakers and 2 battery breakers.
1.2 Model Number Description
DCPS stands for DC Power System
1.3 Features
The DCPS has the following feat res:
Wide voltage range of 85VAC to 300VAC
Comprehensive battery management
Network application over a fast Ethernet (FE) port and an RS485/RS232 port
Comm nication s ch as the Simple Network Management Protocol (SNMP) and Hypertext Transfer
Protocol Sec re (HTTPS) to enable remote management and nattended working
Remote software pgrade
Liq id crystal display (LCD) for display and operations
Web ser interface (Web UI) for display and operations
Display in m ltiple optional lang ages
Hot-swappable DCR rectifiers and DCSC controller
Rectifier power factor p to 0.99
1.4 Work Principles
AC power enters rectifiers thro gh the AC inp ts of the DCD distrib tion panel. The rectifiers convert the AC inp t
into –48VDC o tp t, which is directed by the DC distrib tion to DC loads along different ro tes.
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 res mes, rectifiers power DC loads
and charge batteries again.
The DCSC controller monitors the operating stat s of each component in the power system in real time and
performs appropriate intelligent control. When detecting a fa lt, the DCSC generates an alarm.

systems. The controller provides the system with Battery Management, Energy Conservation, Rectifier
Management, Intelligent Battery Hibernation Mode, Battery Testing, Battery Charging, and C rrent Limiting
controls. System config ration settings and real-time parameters can be accessed either locally (thro gh a two-
line LCD display), or remotely (thro gh a Web User Interface).
