IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This section contains important instructions that should be followed during the installation and maintenance of equipment and batteries. Please read all of the instructions before operating the equipment, and save this manual for future reference.

A licensed electrician MUST perform connections to the branch circuit of service feed. Installation of the power supply and batteries must be performed by, or under the direct supervision of service personnel knowledgeable of the required electrical and battery safety precautions.

If instructions in this manual conflict with local electrical codes, those instructions shall be superseded by the local code.

The following safety symbols will be found throughout this manual, carefully read all information and a bide by the instructions:

DANGEROUS VOLTAGE

This symbol indicates a dangerous voltage

exists in this area of the product.

GAS HAZARD

This symbol indicates a gas hazard

exists in the area of vented batteries.

NO MATCHES OR OPEN FLAMES

This symbol indicates a fire or explosive hazard

exists in the area of the product.

The following levels of warning will be used with the above symbols:

DANGER: You WILL be KILLED or SERIOUSLY INJURED if instructions are not followed closely. WARNING: You CAN be KILLED or SERIOUSLY INJURED if instructions are not followed closely. CAUTION: You CAN be INJURED or equipment can be DAMAGED if instructions are not followed closely.

Mechanical Safety

Keep hands and tools clear of fans. Fans are thermostatically controlled and will turn on automatically. Power supplies can reach extreme temperatures under load. Use caution around sheet metal components and sharp edges.

Electrical Safety

WARNING Hazardous voltages are present at the input of a power system. The DC output from rectifiers and batteries, though not dangerous in voltage, has a high short-circuit current capacity that may cause severe burns and electrical arcing.

Before working with any live battery or power system, follow these precautions:

• Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.

• Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.

• Use OSHA approved insulated hand tools.

Lethal voltages are present within a power system. Never assume that an electrical connection or conductor is not energized. Check the circuit with a voltmeter with respect to the grounded portion of the enclosure (both AC and DC) prior to any installation or removal procedure.

Do not work alone under hazardous conditions.

A licensed electrician is required to install permanently wired equipment. Input voltages can range up to 240Vac. Ensure that utility power is disabled before beginning installation or removal.

Ensure no liquids or wet clothes contact internal components. Hazardous electrically live parts inside this unit are energized from batteries even when the AC input powe r is

disconnected.

Battery Safety

Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel knowledgeable of batteries and the required safety precautions.

Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all metallic objects from hands and neck.

Use OSHA approved insulated hand tools. Do not rest tools on top of batteries. Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other

reproductive harm. Battery post terminals and related accessories contain lead a nd lead compounds; wash hands after handling (California Proposition 65).

WARNING Follow battery manufacturer’s safety recommendations when working around battery systems.

WARNING Do not smoke or present an open flame when batteries (especially vented batteries) are on charge. Batteries vent hydrogen gas when on charge, which creates an explosion hazard.

Batteries are hazardous to the environment and should be disposed of safely at a recycling facility. Consult the battery manufacturer for recommended local authorized recycle r s.

1 Introduction

1.1 Scope of the Manual

This instruction manual covers the features and installation of Argus Technologies’ CXPS 48-1.8-i 48V 150A Power System.

NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.

1.2 Product Overview

The CXPS 48-1.8-i is a complete integrated 48Vdc power system with 150A capacity. The system utilizes the advanced Cordex CXCI controller and 48V 1.8kW rectifier modules. The DCP03 300A distribution center provides front access for DC distribution, site controller, and battery connections.

Cordex rectifier modules use a high frequency, switched mode conversion techn ique to provide a fully regulated and isolated DC output from the AC mains. The rectifier input is wide range to allow use on 120/208/220/230/240/277Vac 50/60Hz electrical service. NOTE: System has de-rated ou tput below 176VAC

input, see specifications at the front of this manual.

Rectifier power modules are “hot swappable” meaning they can be inserted or removed from the shelf with out cutting power to or from the system or the load.

NOTE: Rectifier modules are not included with the base system, but may be purchased along with the system at the tim e

of ordering or added after the shelf has been installed.

The shelf rectifier system is designed to operate with the Argus Cordex System Controller (CXC). This system uses the CXCI integrated version of the controller, which is factory installed on the Cordex rectifier

system shelf. The CXC allows the user to configure, monitor and control the entire DC power system locally or remotely via a

web browser such as Internet Explorer. Features of the unit include temperature compensation, auto equalization, remote access, e-mail alarm notification, battery diagnostics, as well as web server and SNMP support for configuration and monitoring.

Details of controller operation are provided in the current version software manual.

2.2 Distribution Center

2.2.1 Distribution Configurations

The DCP03 contains 18 total AM-type plug-in breaker positions with two-hole connection points for both breaker output and the ground return bus. The breaker distribution, for the CXPS 48-1.8-i, is configured for 4 battery breaker and 14 load breaker positions as shown below:

Battery breaker connections

Figure 2–DCP03 configured for 4 battery and 14 load breakers

Load breaker connections

NOTE: Load breakers require mid-trip AM plug-in breakers, and battery breakers require series-trip AM plug-in breakers. NOTE: When there is no power on the rectifiers and there is only one battery circuit breaker, there will be no alarm if the

circuit breaker trips.

2.2.2 Low Voltage Battery Disconnect (LVBD)

A 400A LVD is included for the CXPS 48-1.8-i system configuration. The LVD is installed in series with the batteries (LVBD).

Argus Technologies Ltd. 053-990-C0 Rev A WC

2.2.3 Shunt

A 400A shunt is included, in the CXPS 48-1.8-i system, for system current measurement. The shunt is installed in series with the batteries and the system controller automatically calculates load current.

2.2.4 Internal Alarm Card

The DCP03 includes a standard alarm card providing a common interface point to internal system I/O connections, an LVD override switch, and LED indication of breaker trip.

The alarm card provides terminal block access to internal signals such as binary alarm s for breaker trip & LVD open, alarm relay for driving LVD, and analog inputs for current (shunt) and voltage measurements. The terminal blocks provide a single point of access to these signals for connecting to an external system controller. Refer to the customer connections (“–08”) drawing at the rear of this manual for details on terminal blo ck assignments.

The LVD override switch provides the user with the ability to inhibit or override LVD contactor operation as a safeguard during controller maintenance. A green LED signals when the LVD is in normal operation mode and a yellow LED signals when the switch has been placed into the override position.

2.2.5 CXCI I/O Terminal Block

A CXCI I/O terminal block kit is installed in the UDC front door for front access to controller signals and interfaces to the CXCI controller, on the rectifier shelf, via a 25-pin D-sub wire harness.

The internal signals from the distribution center are wired to the CXCI I/O board direct from the internal alarm board. The remaining relay outputs, digital inputs, and analog inputs are available on the board via terminal blocks for customer connection of external signals. Refer to the customer connections (“–08”) drawing at the rear of this manual for details on terminal block assignments.
