Mechanical Safety

Keep hands and tools clear of fans. Fans are thermostatically controlled and will turn on a utomatically. 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 eve n when the AC input power 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 and 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.

1 Introduction

1.1 Scope of the Manual

This instruction manual covers the features and installation of Argus Technologies’ CXPS 48-1T 48V 375A Power System.

For advanced detail on the system components used in the CXPS 48-1T, please refer to the following manuals:

• Cordex 48-3.6kW Rectifier Module: 010-600-B2

[This manual also provides CXCM4 (controller) installation details.]

(010-567-20 pre-RoHS)

• Cordex Controller (CXC) Software: 034-109-B2 or latest revision of software.

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 48-1T is a complete integrated 48Vdc power system with 375A initial capacity; expandable up to 600A. The system utilizes the advanced Cordex controller and 48V 3.6kW rectifier modules. The one-tier (Vista II series) distribution center provides front access for DC distribution, site controller, and battery connections.

Cordex rectifier modules use a high frequency, switched mode conversion technique to provide a fully regulated and isolated DC output from the AC mains. The rectifier input is wide range to allow use on 208/220/230/240/277Vac 50/60Hz electrical service.

Rectifier power modules are “hot swappable” meaning they can be inserted or removed fro m the shelf without 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 time

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 CXCM4 modular version of the controller, which plugs directly into the Cordex rectifier system shelf. The rectifier/shelf manual provides CXCM4 installation details.

The CXC allows the user to configure, monitor and control the entire DC power system from its touch screen display similar to that used in a personal digital assistant (PDA). Other 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.

Argus Technologies Ltd. 053-392-C0 Rev A WC

2.3.3 Analog Input Channels

The CXCM4 has analog input channels for voltage, current, and temperature.

2.3.3.1 Voltage Inputs

Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage. The CXCM4 software is pre-configured to monitor V2 for both load and battery voltage. V2 is used as the system reference for rectifier float voltage, low voltage disconnect (LVD), system high voltage alarm, and system low voltage alarm. V1 is available for additional voltage measurements.

2.3.3.2 Current Inputs

The CXCM4 software is pre-configured to monitor for load current using an external 50mV current shunt.

2.3.3.3 Temperature Inputs

Two temperature input channels, T1 and T2, provide monitoring of battery temperature and temperature compensation (temp comp) or room/ambient temperature. A voltage is supplied by the CXC to these terminals to power the temperature sensors.

2.3.4 Digital Input Channels

The CXCM4 can accommodate up to four channels and can monitor digital alarm/control signals from rectifiers, converters and many other types of equipment.

2.3.5 Alarm and Control Output Relays

The CXCM4 contains eight Form C digital alarm output relays to extend alarms and control ex ternal apparatus. Each internally generated alarm or control signal may be mapped to any one of the relays, or, several signals may be mapped to just one relay or none at all.

2.3.5.1 LVD Control (External Option)

The LVD Control functions can be hardwired directly from the assigned relay output to an optional LVD override control and distribution alarm card. This provides a safety measure to protect against load disconnect during CXCM4 reset or replacement; e.g. when the controller is off-line. Operators may also perform test and maintenance procedures on the CXCM4 without disturbing the load.

2.3.6 System Fail Alarm/Relay

The CXCM4 system fail alarm (K0) activates because of a major internal failure. Durin g such a condition, the unit will attempt to reset, but if this fails, an alarm condition will be extended to a relay and the red LED on the front panel will illuminate. This is a fail-safe signal to the remote monitoring equipment; i.e. alarm will be extended even if power to the unit is interrupted.

2.3.7 Network Connection and Remote Communications

The Cordex system can be set up, monitored and tested via ETHERNET 10/100 Base-T serial data connec tion. The communication protocol supports a web interface. All alarming and control of Cordex rectifiers is accomplished with a CXC via a CAN bus.

A step-by-step connection wizard – provided to establish remote communications with your CXC – is available via the Argus website (www.argusdcpower.com).
