The 12kW rectifier has three connectors. 3.3 True Module Fail Alarm The power modules have a “true” fail alarm that provides a true indication of the power module’s ability to source current.

  • Page 15: Ac Inrush/Transient Suppression

    3.7 AC Inrush/Transient Suppression To prevent a surge on the AC inout line, the inrush current of a rectifier module is limited to the full load steady state line current. Modules are also protected from input lightning and transient surges in accordance with IEEE/ ANSI C62.41 Category B3 standards.

    4. Cordex System Controller (CXC) 4.1 CXCM4 Features The CXCM4 (Cordex Controller, Modular, 4RU) is mounted in the rectifier system shelf and brings advanced monitoring technology to the Cordex series of rectifiers. This compact system controller is designed for seamless operation and set up for Alpha power systems.

  • Page 17: Reset Button

    LEDs The three LEDs, located on the CXCM4 front panel, display the alarm status of the power system, CXCM4 prog- ress and status during startup, and file transfers. Alarm Conditions The CXCM4 illuminates the LED that corresponds to the system alarm status. Each LED color corre- sponds to a specific alarm status (only one LED is illuminated at a time during alarm conditions.) OK, no alarms present.

    4.5 Digital Input Channels The CXCM4 can accommodate up to four channels and can monitor digital alarm/control signals from rectifiers, converters, and other types of equipment. 4.6 Alarm and Control Output Relays The CXCM4 contains eight Form-C digital alarm output relays that are used to extend alarms and to control external apparatus.

  • Page 20: Inspection

    5. Inspection 5.1 Packing Materials All Alpha products are shipped in rugged, double walled boxes and suspended via solid inserts to minimize shock that may occur during transportation. Packaging assemblies and methods are tested to International Safe Transit Association standards. Rectifiers and batteries are shipped on individual pallets and are packaged according to the manufacturer’s guidelines.

  • Page 21: Installation

    6. Installation The equipment is suitable for installation in Network Telecommunication Facilities. WARNING! This system is designed to be installed in a restricted access location that is inacces- sible to the general public. The following procedure is written for qualified personnel to install this product in a clean and dry environment. For the battery installation, refer primarily to the manufacturer’s manual.

  • Page 22: Power System Assembly And Mounting

    6.3 Power System Assembly and Mounting 6.3.1 Shelf Preparation/Mounting NOTE: Mount the shelf in a clean and dry environment. Allow at least 1.75” of free space in front of the unit for unrestricted cooling airflow. Sufficient free space must be provided at the front and rear of the power system.

  • Page 23: Wiring

    7. Wiring This chapter provides cabling details and notes on cable sizing for DC applications using the Cordex 48-3.6kW, 4.0kW and 12kW modular switched mode rectifier systems. Refer to the Safety section on page 5 for safety precautions. WARNING! Ensure that the power at the AC service panel is off is switched off. Remove battery line fuses or connections before attempting work on the wiring.

  • Page 24: Dc Output Connections

    7.3 AC Input Connections CAUTION! To minimize EMI disturbances, route the AC input wires in flexible or rigid conduit and located as far away as possible from the DC power wires. WARNING! Use care when removing or replacing the covers for the AC input connections. Never assume that an electrical connection or conductor is not energized.

  • Page 25: Can Serial Ports (Rectifier Shelf)

    7.5 CAN Serial Ports (Rectifier Shelf) Two CAN Serial ports (modular jacks with offset latches), are provided for communications with Alpha’ Cordex rectifiers and other CAN-enabled equipment. These are located on the left side of the rectifier shelf as viewed from the front.

  • Page 26: Inserting The Cxcm4 Module

    7.6 Inserting the CXCM4 Module NOTE: Do not force a module into position if it does not seat properly. All modules are keyed to ensure that the correct module (voltage/polarity) type is used. 1. Insert by placing the controller on the shelf bottom and sliding the module into the CXCM4 connection interface (inside of the shelf, see drawing 747-271-08).

  • Page 27: Figure 7 - Digital Input Connection Method

    7.7.2 Digital Inputs The digital input channels are used to monitor various alarm and control signals. All input channels are voltage activated and accept a bipolar (negative or positive) DC signal directly. Connection Method Typical Alpha systems use the “reset with Hot and trigger with Ground” connection. The digital input is wired in such a way that the Hot is wired directly into one of the input terminals.

  • Page 28: Network Connection And Remote Communications Via Cxc

    Voltage Input #2 (battery voltage per CXC software) is wired internally (V2) to the rectifier output voltage of the shelf. This is used as the reference for system alarming (such as high voltage) and control (such as low voltage disconnect). Temperature Sensing Temperature Probe input channels provide connections for temperature sensors.

  • Page 29: System Startup

    8. System Startup Visually inspect the installation thoroughly. After completing the system installation and power system wiring, perform the following startup and test proce- dure to ensure proper operation: 8.1 Check System Connections 1. Make sure that the AC input power is switched off, the batteries are disconnected, and all the power modules are removed from the shelf.

  • Page 30: Rectifier States, Modes And Factory Defaults

    9. Rectifier States, Modes and Factory Defaults 9.1 Main Rectifier States The rectifier operation can be broken up into five main states: 1. Off. 2. Start delay. 3. Soft start. 4. Normal operation. 5. Switching off. Each state is characterized as being distinct and necessary for the operation of the rectifier. These states are briefly described below.

  • Page 31: Main Rectifier Modes

    9.2 Main Rectifier Modes In addition to the main rectifier states, there is a set of main rectifier modes. These modes can be divided into two categories, the output voltage mode and the output current/power mode. 9.2.1 Output Voltage Modes Voltage modes can be thought of as modes that, under software control, can directly adjust the output voltage.
