Electrical Safety Warning: Hazardous voltages are present at the input of power systems. The DC output from some rectifiers and batteries can have high voltage and 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: Page 6 9400021-J0 Rev B

• Remove all metallic jewelry, such as watches, rings, metal rimmed glasses, or necklaces. • Wear safety glasses with side shields at all times during the installation. • Use OSHA approved insulated hand tools. Do not rest tools on top of batteries. Warning: Lethal voltages are present within the power system. Always assume that an electrical connection or conductor is energized. Check the circuit with a voltmeter with respect to the grounded portion of the enclosure (both AC and DC) before performing 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 the utility power is disconnected and locked out before performing any installation or removal procedure. • Ensure that no liquids or wet clothes come into contact with internal components. • Hazardous electrically live parts inside this unit are energized from the batteries even when the AC input power is disconnected. • The enclosure which contains the DC or AC power system along with customer installed equipment must remain locked at all times, except when authorized service personnel are present. • Always assume electrical connections or conductors are live. Turn off all circuit breakers and double-check with a voltmeter before performing installation or maintenance. • Place a warning label on the utility panel to warn emergency personnel that a reserve battery source is present which will power the loads in a power outage condition or if the AC disconnect breaker is turned off. • At high ambient temperature conditions, the internal temperature can be hot so use caution when touching the equipment. Warning: The intra-building ports (Ethernet, CAN, Alarm relays) of the equipment or subassembly are suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. Warning: Controller Ethernet port is not designed to withstand lightning and AC power cross surges according to the NEBS requirements in GR-1089-CORE. Ensure that any Ethernet cable used (not provided by Alpha) does not exceed a maximum length of 6 meters. Battery Safety • Never transport an enclosure with batteries installed. Batteries must ONLY be installed after the enclosure has been securely set in place at its permanent installation location. Transporting the 9400021-J0 Rev B Page 7

Battery post terminals and related accessories contain lead and lead compounds. Wash your hands after handling batteries. Warning: Follow battery manufacturer’s safety recommendations when working around battery systems. Do not smoke or introduce an open flame when batteries (especially vented batteries) are charging. When charging, batteries vent hydrogen gas, which can explode. • Batteries are hazardous to the environment and should be disposed at a recycling facility. Consult the battery manufacturer for recommended local authorized recyclers. Page 8 9400021-J0 Rev B

shelf systems: • Cordex® 24-400W integrated 19" 2RU shelf system with up to 1600W output power and distribution. • Cordex® 24-400W integrated 19" 2RU shelf system with up to 2000W bulk output power. • Operation of the Cordex® 24-400W rectifier. 2.2. Product Overview A complete Cordex® rectifier system consists of a controller with one or more power modules in a common shelf enclosure. The shelf has connections for AC inputs, DC output, and system communications. 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 120/208/220/240Vac 50/60Hz electrical service. Rectifier power modules are “hot swappable” meaning they can be inserted or removed from the shelf without cutting power to or from the system or the load. Additional power modules can be included 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 Alpha CXCi series of controllers (includes CXCi+ and CXCi HP), which is built into the rectifier system shelf. All models of the controller allow the user to set up, control and monitor the entire power system and its components from one central, easy-to-use source: your web browser. The CXCi series of controllers do not have a touch screen display, system setup and management is performed exclusively with the web interface. Details of controller operation are provided in the current version software manual. The following figures are examples of: 1. Cordex 48-400W integrated 19" 2RU shelf system: four rectifiers, controller, and breaker distribution. 2. Cordex 48-400W integrated 19" 2RU shelf system: five rectifiers and controller. 9400021-J0 Rev B Page 9

conversion technology featuring high power conversion efficiency. All internal semiconductor devices operate under “soft-switching” conditions and exhibit very low power loss. The reduced power loss leads to lower thermal stress on the semiconductors and thus improves reliability. Rectifier Front Panel Figure 3. Rectifier Front Panel LEDs The front panel LEDs provide rectifier status summary and help to locate a specific module with the controller. OK The top LED (green) is on when AC is within valid range and the rectifier is delivering power to the load. The LED will flash (~2Hz) when AC is outside the nominal range – AC voltage is invalid if the AC Mains Low or AC Mains High alarm is active. The LED turns off when AC has failed (or no AC power is present). 9400021-J0 Rev B Page 11

Alarm The bottom LED (red) is on continuously in the event of an active Module Fail alarm. The LED flashes (~2Hz) when a minor alarm is detected. The LED remains off in the absence of an alarm. LED Activity During “Locate Module” Command from Controller When the “locate module” command has been received from the controller, the LEDs behave in a distinctly different way so that the rectifier is easier to visually identify among adjacent rectifiers. This state is entered when commanded via the controller. The LEDs flash in a distinct pattern repeating every two seconds. LED Activity During Firmware Upload When a rectifier firmware upload is in progress, the LEDs behave in the same way as the locate module command described above. Mechanical A thumbscrew is provided to secure the rectifier into the shelf. During normal operation the rectifier shall be locked into position. A handle (or grip) is incorporated into the front panel to facilitate the removal of the rectifier from the shelf. No special tools are required. True Module Fail Alarm The power modules have a “true” fail alarm. This provides a true indication of the power module’s ability to source current. When the module’s output current drops below 2.5% of the rated output a low output current condition is detected and the Module Fail detection circuit is activated. This circuit momentarily ramps up the output voltage to determine if the module will source current. If no increase in current is detected, the Module Fail alarm is activated. The module will test once every 60 seconds for the condition until current is detected. Output voltage ramping will cease upon detection of current1. A minimum 2.5% load is required to avoid the Ramp Test Fail alarm; this can typically be provided with the parallel system battery. Activation of this alarm could indicate a failed module or a failed load. Note: For rectifier systems without batteries (or with a very light load; below 2.5% of rated output) it is recommended that the ramp test be disabled to avoid nuisance alarms. The Ramp Test feature is enabled/disabled via the controller. Refer to the software manual for detailed information. Heat Dissipation Heat dissipation is achieved through natural (bottom to top) convection cooling Over Temperature Protection Each rectifier module is protected in the event of an excessive increase in temperature due to component failure or cooling airflow blockage. During over temperature conditions, the rectifier limits the output power as well as the output current. If temperature continues to increase, a shutdown of the rectifier is initiated. The rectifier shall restart automatically if the temperature has returned to a safe level. 1. Under normal conditions, a battery connected to the output of the rectifier will draw current when the voltage ramp occurs. Therefore the rectifier fail alarm will not be generated with a battery connected. Page 12 9400021-J0 Rev B

Wide AC Range A minor alarm is generated when the AC input voltage drops below specification. The unit will deliver derated output power down to 60Vac. • Note: Output power is reduced linearly between 90Vac to 60Vac to 0% of the rated output power. At a lower voltage the module will shutdown and will not restart until the AC is greater than 65Vac. For voltages between 276Vac and 320Vac, the rectifier may not be operational but shall not suffer any damage. AC Inrush/Transient Suppression An external surge suppressor is not required at the AC input, modules are protected from input lightning and transient surges in accordance with IEEE/ANSI C62.41 Category B3. Soft Start To eliminate an instantaneous demand on the AC source, a soft start feature is employed. Soft Start, sometimes referred to as “current walk-in”, works by gradually (up to five seconds) ramping the current limit up from zero to the actual or defined customer setting. The rectifier output voltage is ramped up from the minimum voltage to the float voltage. Start Delay The rectifier modules are equipped with a delay timer in order to stagger start a series of modules to prevent excessive loading of generators upon start up. The built-in timer delays the start up of the module depending on the value selected (up to 120 seconds on CXCi and 250 seconds on CXCi HP) via the controller. A minimum one-second delay is preset to allow charging of the input capacitors. Current Limit/Short Circuit Protection The current limit function determines the maximum output current limit of the rectifier module, regardless of output voltage or power. Maximum output current is limited to a constant value down to short circuit condition. Current limiting can be used to mate the rectifier output current ampacity to the needs of the load and parallel battery to minimize excessive battery recharge current. The rectifier will sustain a short circuit at the output terminals indefinitely. The maximum short circuit current cannot exceed 105% of the rated full load current. Power Limiting Each rectifier module is designed to limit power output to the module specification. This enables more current to be supplied at lower output voltages, and allows matching of output to the demand of constant power loads, normally seen with telecom equipment. This feature may also be used for a faster recharge of flooded batteries paralleled with the load. Note: Current limiting overrides the power-limiting feature. 9400021-J0 Rev B Page 13

High Voltage Shutdown (HVSD) This feature provides protection to the load from over voltage conditions originating from the rectifiers. It operates by shutting down the offending rectifier module when a high output voltage condition occurs. Indication is through the red Alarm (Module Fail) LED. Modules will restart automatically; however, if more than three over voltage conditions occur in one minute, the module will latch off and remain shut down until it is reset. Battery Eliminator Operation Rectifier modules maintain all specifications (except where indicated) with or without a battery attached in parallel to the output; however, if a battery or another module supplying DC voltage in parallel is not present, there will be no monitoring or control activity if there is an AC power failure or input fuse failure. 3.2. Overview of the CXCi HP The CXC HP in-shelf controllers have a small organic LED (OLED) display. This display shows 30 characters total (five lines high, six characters wide) and the controller has three navigation buttons and one reset button. The in-shelf display has three main operating modes: dashboard, menu and screen saver. After 20 minutes with no activity, the in-shelf controller goes into screen saver mode and the display shuts off. From screen saver mode, press any of the three navigation buttons to re-activate the screen and enter dashboard mode. Figure 4. CXCi HP Controller System Status LEDs LED Screen Forward and Back buttons to scroll through menus and Select button to execute Ethernet Port USB Port Reset Display In dashboard mode, the in-shelf display shows the key operating parameters of a system. For example, output voltage and load current. If more than one system is defined, you can cycle between systems using the Forward and Back buttons. With multiple systems, you can specify a default system, which is then displayed first. Refer to the software manual for set up. Page 14 9400021-J0 Rev B

Only one LED is illuminated at a time during alarm conditions: • Green: OK, no alarms present • Yellow: Minor alarm is present (no major alarms) • Red: Major alarm is present. Progress and Status Indication The LEDs are also used in the following situations: • Base unit validation: All three LEDs on simultaneously • File transfer: Red LED illuminates when recovering from invalid firmware application • Lamp Test: All three LEDs flash in sync for two seconds Reset (CXCi+ only) A reset button is located on the front panel for restarting the controller. During reset, the controller may occasionally need to run a defragmentation cycle. This can be recognized by the LEDs cycling on 9400021-J0 Rev B Page 17

the front panel. A full defragmentation may take up to 20 minutes to perform, do not power down the controller during this time. Note: Refer also to the software manual – always select the Reset menu item before pressing the reset button. 3.4. Controller Input and Output The inputs and outputs refer to both the CXCi+ and the CXCi HP controllers. Ethernet Port The Ethernet port is designed for connection to a user supplied network (TCP/IP secured by user) via a front panel RJ-45 jack and a standard network cable. Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network cable. Analog Input Channels The controller is provided with analog input channels for voltage, current, and temperature. Voltage Inputs Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage. The controller software is pre-configured to monitor V1 for battery voltage and V2 for load voltage. V2 is wired internally to the rectifier shelf to provide a reference for rectifier float voltage, low voltage disconnect (LVD), system high voltage alarm, and system low voltage alarm. Wire V1 to battery to monitor battery voltage or change battery setting from V1 to V2 in Signals > Configure Signals. Current Inputs The controller software is pre-configured to monitor I1 for load current wired internally to the load current shunt. 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 to these terminals to power the temperature sensors. Digital Input Channels The controller can accommodate up to two channels and can monitor digital alarm/control signals from rectifiers, converters and many other types of equipment. Alarm and Control Output Relays The controller contains four Form C digital alarm output relays to extend alarms and control external 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. Page 18 9400021-J0 Rev B

Network Connection and Remote Communication The Cordex® system can be set up, monitored and tested via an Ethernet connection. The communication protocol supports a web interface. All alarming and control of the rectifiers is accomplished with a controller via a CAN bus. A step-by-step connection wizard – provided to establish remote communications with your controller – is available via the Alpha website (http://www.alpha.ca/downloads). Controller Connections Located on the rear of the shelf are terminal block connections for the system control I/O; such as, digital signals, analog inputs, and alarm relay outputs. USB Port (CXCi HP Only) A USB 2.0 port is located on the front of the CXCi HP controller. It is used for upgrading operating system software. 9400021-J0 Rev B Page 19

and dry environment. Note: Drawings are located at the rear of the manual. Warning: This system is designed to be installed in a restricted access location that is inaccessible to the general public. 5.1. Safety Precautions Warning: Hazardous voltages are present at the input of power systems. The DC output from the rectifiers and battery system, 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/distribution center, 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 insulated hand tools. The installer should follow all applicable local rules and regulations for electrical and battery installations; e.g., CSA, UL, CEC, NEC, OSHA, and local fire codes. 5.2. Shelf Preparation/Mounting Warning: This system is designed to be installed in a restricted access location that is inaccessible to the general public. Note: The shelf is designed for mounting in a clean and dry environment. Allow at least 1.75" (44mm, 1 RU) of free space above and below the unit for unrestricted cooling airflow. 3.5" (89mm, 2RU) is recommended. Each shelf has been designed for flush or offset mounting in a 19" (483mm) or 23" (584mm) rack. See drawings at the end of this manual. Mounting brackets accommodate either 1" (25.4mm) or 1.75" (44mm) rack spacing. Mount the shelf to the rack using at least two #12 – 24 x 1/2" (12.7mm) screws in each bracket. Use Phillips-type screws and screwdriver to eliminate the possibility of slippage and scratching of the unit’s exterior. An electrical conducting path must exist between the unit’s chassis and the metalwork of the enclosure in which it is mounted or a grounding conductor. The electrical continuity requirement can be met by the use of thread-forming type unit mounting screws and star washers that remove any paint or non-conductive coatings and establish metal-to-metal contact. 9400021-J0 Rev B Page 21

5.3. Module Insertion and Removal The rectifier is plug and play. When a rectifier module is added to the system, the controller will detect and update the inventory automatically. Replacing an installed rectifier requires a manual Inventory Update at the controller to clear the removed rectifier from its current list of rectifiers. Insert rectifiers by placing the module on the shelf bottom and sliding the module into the rear connector (inside of the shelf). Apply pressure on the front of the module to engage the rear connector in the shelf receptacle. A thumbscrew is provided to secure the rectifier into the shelf. Note: Do not force a module into position if it does not seat properly. All modules are keyed to ensure that the correct module (polarity/voltage) type is used. 5.4. Removing a CXRC Rectifier 1. To remove a module, loosen the screw on the bottom of the faceplate. Thumb Screw 2. Grasp the handle and pull out, sliding the module away from the rear connector and out of the shelf. 3. Place the new rectifier module on the shelf bottom and slide the module into the rear connector (inside the shelf). 4. Apply pressure to the module front panel to engage the rear connector in the shelf receptacle. 5. Tighten the thumb screw to secure the rectifier to the shelf. 6. Refer to the respective controller software manual to perform an inventory update or module assignment. 5.5. Removing the CXCi HP and CXCi+ Controller To remove the controller: 1. Remove at minimum the left most rectifier adjacent to the controller. 2. Remove the controller mounting screws as highlighted in figure below. Page 22 9400021-J0 Rev B

Remove controller mounting screws 3. Pull from the location noted in the following image to remove the controller. Pull here to remove the controller from the shelf CAUTION: When removing the controller in a live system that has an LVD, ensure that the LVD override jumper is set to correct position to avoid possible service disruption. Refer to the wiring and connections section of the manual and the connection drawings. 9400021-J0 Rev B Page 23

6.1. Safety Precautions Warning: Hazardous AC voltages may be present. Ensure power at the AC service panel is off before attempting work on the AC connections. Use a voltmeter to verify the absence of voltage. Clearly mark the correct polarity of the battery leads before commencing work on DC connections. Refer to the chapter on Installation for additional safety precautions. 6.2. Tools Required Various tools are essential for product installation. Insulated tools are recommended. Use this list as a guide: • Slot head screwdrivers (blade sizes: 1/4", 1/8", 1/16") • Phillips head screwdriver, #2 (tip size 3/16") • Digital voltmeter equipped with test leads • Adjustable 24/48Vdc load (optional) • Cutters and wire strippers • Crimping tool (optional for large gauge wire) • Socket and ratchet set (Imperial measure) • Anti-static wrist strap • Computer (laptop) with web browser • Standard network cable (for access using the Ethernet port) 6.3. Power System Chassis Ground and DC Ground Warning: For safety reasons, ensure the system is properly bonded to the building’s ground. Both the shelf chassis ground (via power system chassis ground) and common return (DC ground) shall be connected to the site ground to ensure correct operation of the system and to prevent drifting floating analog (especially current) readings. 6.4. AC Feeder Protection/Sizing To maximize system reliability, the AC feed divides the rectifiers into groups to be supplied by separate feeds. See customer connections drawing (modules are numbered left to right). • Shelves with integrated distribution have TB3 feed modules 1 and 2 while TB4 feeds modules 3 and 4. • Shelves with bulk outputs have TB3 feed modules 1 and 2 while TB4 feeds modules 3, 4 and 5. Page 24 9400021-J0 Rev B

It is recommended, for each feed, to use a dedicated protection feeder breaker located at the AC distribution panel. The feeder breaker can also act as the disconnect device for the connected modules. Table 2. Recommended AC Supply Configuration AC Input (Vac) Number of Recti- fiers on AC Feed Circuit Breaker, Ex- act Value to Use (A) 90° C Wire Gauge to use at 30° C ambient (AWG) 120/240 1 10 or 15 14 120/240 2 20 12 120/240 3 20 12 An external surge protection device is not required. The rectifiers are protected by internal MOVs. 6.5. AC Input CAUTION: Route the AC input wires in flexible or rigid conduit as far away as possible from the DC power wires to minimize EMI disturbances. 1. If the shelf is factory-equipped with a line cord, proceed to the next section. 2. Refer to the -08 customer connections drawings (rear view – back cover removed). 3. Remove the metal cover from the rear of the shelf to expose the wire-way for the input terminal blocks. 4. Attach the conduit retainers to the wire-way hole(s) and route the AC cables through. 5. Secure the wires to the AC input and chassis ground terminals as required. Tighten the cable connector to the AC cable (conduit similar). 6. Replace rear cover once all connections have been completed. 6.6. Calculating Output Wire Size Requirements Wire size is calculated by first determining the appropriate maximum voltage drop requirement. Using the formula below calculate the CMA wire size requirement. Determine the size and number of conductors required to satisfy the CMA requirement. CMA = (A x LF x K) / AVD, where: • CMA: Cross section of wire in circular MIL area • A: Ultimate drain in amps • LF: Conductor loop feet • K: 11.1 constant factor for commercial (TW type) copper wire • AVD: Allowable voltage drop 9400021-J0 Rev B Page 25

Check again that the ampacity rating of the cable meets the requirement for the installation application. Consult local electrical codes (NEC, CEC, etc.) for guidelines. If required, increase the size of the cable to meet the code. Example: A = 40A LF = 20 feet K = 11.1 AVD = 0.5V CMA = (A x LF x K) / AVD CMA = (40A x 20ft x 11.1) / 0.5A CMA = 17,760 In this example the technician would need to use a 7 AWG or larger. This value can be found from a standard AWG table. 6.7. DC Output Warning: Leave cables disconnected at battery and verify output polarity using a voltmeter. Make battery connections only after all other wiring is completed. DC output wire must be UL approved XHHW or RHH/RHW (for Canadian users RW90; for European users, must be EN or IEC approved wire). Control and sense wires must be UL approved 1015 (for Canadian users TEW type; for European users, must be EN or IEC approved wire). Circuit Breaker Distribution Four Module shelf: equipped with four AM-style bullet type breakers, factory configurable as four load breakers or two load breakers plus two battery breakers, or three load breakers plus one battery breaker. Five Module shelf: bulk output only. Note: Battery breakers should be series-trip to ensure effective alarm operation; service personnel must reset the breaker to clear the alarm. Note: When there is no AC power to the rectifiers and there is only one battery circuit breaker, there will be no alarm if the circuit breaker trips. Secure the positive and negative cable leads to the shelf output terminal blocks of the correct polarity; i.e., +Vcable to +Vpost. The common output leg of the rectifier system should be connected to ground. This is typically done at the load common termination point. For the output terminal block configurations, refer to the schematics drawings at the rear of this manual. Page 26 9400021-J0 Rev B

6.8. CAN Ports Four Module shelf: one CAN OUT port located at the rear of the shelf. Five Module shelf: one CAN IN and one CAN OUT port. Located at the back of the shelf. Daisy-chain from node to node (CAN OUT of one node to CAN IN of another) as necessary and ensure that only the last node is terminated. Note: This system can accommodate up to a maximum of 12 Cordex® small convection cooled rectifiers (650W, 400W, 250W). The individual rectifiers do not provide their own CAN bus power and must draw it from the controller. 6.9. Network Connection and Remote Communications via the Controller The Cordex® rectifier shelf systems can be set up, monitored and tested via modem or Ethernet 10/100 Base-T serial data connection. The communication protocol supports a web interface. Some standard scenarios are described in the following sections. Ethernet Port for Network Connection The Ethernet port is designed for controller connection to a user supplied network (TCP/IP secured by user) via a front panel RJ-45 jack. Connect to the controller using a standard network cable. Pinouts are shown in the connection drawings. Ethernet Port for Local Connection Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network cable. Note: Older CXCi models must use a crossover Ethernet cable for direct connection to a computer. 6.10. Signal Wiring Connections For terminal block connections, the recommended wire sizes are #16 to #26 AWG (1.5 to 0.129mm2). Control and sense wires shall be UL approved Style 1015 (for Canadian users, TEW type; for European users, EN or IEC approved wire). CAUTION: To reduce the risk of fire, use only #26 AWG (0.129mm2) or thicker wire. Table 3.

Can be configured to de-energize on alarm (DOA) or energize on alarm (EOA).** See Table 4: Voltage Level Definitions for Digital Inputs (on page 30) for definitions of logic and system.*** Voltage (Input) is 0—60VDC, Temp Probe is 0—5VDC with power source. Note: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual. Custom configurations may be detailed within the Alpha power system documentation package. Bundle the signal cables together and route them through the entry holes of the shelf. Analog Inputs CAUTION: Ensure the correct polarity is used for all input cable terminations. The analog input channels are used to monitor various types of electrical signals. The Voltage Input is -60 to +60Vdc. The Temperature Input (designed for Alpha supplied temp sensor only) is 0 to 5Vdc with power source. Voltage Voltage Input #1 terminals on the shelf provide connections to an optional secondary voltage input. Voltage Input #2 is wired internally to the rectifier output voltage of the shelf. This is used as the reference for Voltage regulation of rectifiers, system alarming (such as high voltage) and control (such as LVD). See the software manual for information on configuring Alarms and LVD control. The battery should be connected at the battery system voltage terminal for redundant power feed to the CXCi series controller when a battery disconnect device is used. It is critical to controller operation as it ensures an auxiliary source of power to the controller should the disconnect device open the circuit. Current Page 28 9400021-J0 Rev B

Current input #1 is wired internally to the system current shunt for shelves with integrated distribution, and wired to an external shunt for bulk distribution shelves. Temperature Sensor Temperature Probe input channels provide connections for up to two temperature sensors. A voltage is supplied to these terminals for sensor measurements. Temperature sensors are available from Alpha in various lengths. 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 (i.e. negative or positive) DC signal directly. For shelf modules with integrated distribution, D1 is wired internally for CB/fuse trip. D2 is available for customer connections as required. 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: • positive input for +12V and +24V systems • negative input for -48V systems The other input terminal is wired to the Ground (common) of the system through a relay (dry contact – usually located on the equipment requiring monitoring). This method allows the digital input to receive (or not receive) a Ground signal on an alarm. Figure 10. Digital Input Connection Method VE Ground Hot Hot VE Hot Relay from Equipment VE Hot VE Ground Relay from Equipment Digital Input 12V and 24V Systems Digital Input 48V Systems Programming the Digital Input The digital input channels can be programmed for “active high” or “active low. Active high indicates, “alarm on the presence of a ground signal” and active low indicates, “alarm on the removal of a ground signal.” See controller software manual for detailed instruction on programming. 9400021-J0 Rev B Page 29

Table 4. Voltage Level Definitions for Digital Inputs V Voltage Level (Vdc), Considered As “0” (Off) Voltage Level (Vdc), Considered As “1” (On) 0 - 60 (System Voltage Setting) 0 to 3V 9 to 60V Alarm Relay Outputs Terminals provide contacts for extending various alarm or control signals. Each relay output can be wired for NO or NC operation during an alarm or control condition. Figure 11. Relay Connections NO Normally Open Normally Closed Common C NC Relays can be programmed to energize or de-energize during an alarm condition (see controller software manual). When the controller reset button is pressed or power is lost, all relays de-energize. These relays could be used for additional external LVD contactor control; however, this would not provide the redundant LVD control as with the assigned output pins described below. LVD Control (Load Disconnect or Battery Disconnect) The disconnect option is controlled by and connected internally to relay K1, when applicable. LVD Inhibit Should it be necessary to remove a CXCI series controller, the customer connection board (on the rear of the shelf) provides shorting pins (JP2) to inhibit (or override) the LVD Control function. See the customer connections drawings. If the LVD is controlled on NC contacts (factory default for LVD option), then JP2 pins 1 and 2 must be shorted together to maintain LVD operation. If the LVD is controlled on NO contacts, then pins 2 and 3 must be shorted together. For normal operation, the factory-supplied shorting jumper should be left on pins 3 and 4. LVD Control Alternative The LVD Control functions can be hardwired directly from an alarm output relay to an external LVD contactor (or panel). See Controls Menu Defaults in the controller software manual. Page 30 9400021-J0 Rev B

Rectifier operation has five main states; each state is distinct and necessary for the operation of the rectifier. • Off • Start Delay • Soft Start • Normal Operation • Turning Off Off The rectifier is in the Off state immediately after power is applied to the rectifier or after a rectifier shutdown (remote or local shutdown, AC shutdown, OVP or thermal shutdown). In this state the DC-DC converter is turned off and the controller monitors its inputs for the proper conditions to begin the start up sequence. When the conditions have been met for the rectifier to start up, it transitions to the Start Delay state. Start Delay When the rectifier is in the Start Delay state, the DC-DC converter is held off and still not sourcing power, waiting for a given amount of time before transitioning to the next state. The controller continues to monitor its inputs. After the Start Delay state the rectifier transitions to the Soft Start state. Note: Soft start, or current walk-in, gradually increases the voltage and current output of the rectifier upon startup. This is done to reduce the instantaneous load on the AC source. Soft Start When the Soft Start state is entered, the rectifier is turned on and the output voltage and output current gradually increased. If a load is present, the rectifier begins to source power. When the voltage and current limit ramps have finished, the rectifier will transition to the Normal Operation state. Normal Operation The Normal Operation state is the state that the rectifier will be in performing all of the rectifier functions and features specified herein. From this state, the only valid transition is to the Turning Off state. This transition will happen if the rectifier is required to shut down. 9400021-J0 Rev B Page 31

Turning Off The Turning Off state is entered because a short delay is required before the rectifier actually turns off to take care of any initialization requirements. When this short delay has elapsed, a transition to the Off state is made. 7.2. Main Rectifier Modes In addition to main rectifier states, there is a set of main rectifier modes. These modes are divided into two categories: Output Voltage Modes Voltage modes, under software control, can directly adjust the output voltage. Situations, such as the rectifier being in current limit, can change the output voltage with no software control. The following table describes the five output voltage modes. Table 5. Output Voltage Modes Output Volt- age Modes Active when... Float Output voltage is set to the float voltage setting. Equalize Output voltage is set to the equalize voltage setting. Battery Test Output voltage is set to the battery test voltage setting. Safe Output voltage is set to the safe mode voltage setting. Manual Test Output voltage can be manually adjusted outside of the standard adjustment ranges. Output Current/Power Modes These four output current/power modes directly affect the output current and power: Table 6. Output Current/Power Modes Output Cur- rent/Power Mode Output current and power limit have been reduced due to: Temperature foldback mode High temperature of the heatsink or internal ambient temperature sensor. AC foldback mode Low AC input voltage. Note: Reduces the risk of tripping an AC breaker due to increased AC current draw as the AC voltage decreases. Short circuit foldback mode Short circuit at the output. Internal fault foldback mode Internal fault. Page 32 9400021-J0 Rev B

7.3. CAN Bus Communication The CAN bus is used for commands and data transfer between the rectifier and controller to configure the rectifier with system settings and to monitor rectifier status. 7.4. Factory Ranges and Defaults The following table lists the rectifier controller settings/ranges/defaults. These settings are for a 24V system. Table 7. Factory Ranges and Defaults Setting Range (minimum to maximum) Default Float (FL) Voltage 23.75 – 29.30V 27.00V Equalize (EQ) Voltage 24.90 – 29.30V 27.50V Battery Test (BT) Voltage 22.00 – 26.00V 23.00V Over Voltage Protection (OVP) See note below – 30.30V 28.50V Current Limit (CL) 23 – 100% 100% Power Limit (PL) 0 – 100% 100% Module Start Delay 0 – 250s 1s System Start Delay 0 – 600s 0s Low Voltage Alarm (LVA) 21.00 – 26.00V 22.00V High Voltage Alarm (HVA) 26.00 – 30.30V 27.75V Equalization (EQ) Timeout 1 – 2399h 30h Battery Test (BT) Timeout 1 – 250h 8h Softstart Ramp-rate Normal/Fast Normal Current Limit / Power Limit Alarm Enable/Disable Enable Remote Shutdown Enable/Disable Enable Ramp Test Enable/Disable Enable Note: OVP cannot be set below the present system/FL/EQ/BT voltage setting or the safe mode voltage of 25.7V. 9400021-J0 Rev B Page 33

8.1. Check System Connections • Ensure AC is off, battery is disconnected, and all power modules are removed from the shelf. • Verify the polarity of all connections. 8.2. Verify AC and Power the Shelf • Install one power module. • Verify AC input voltage is correct and turn on the corresponding AC input feeder breaker. • The power module OK LED should illuminate after a preset start delay. • Using the controller, test functionality of various module alarms and controls. 8.3. Check Battery Polarity and Connect • Verify correct battery polarity using a voltmeter (ensuring no cells or batteries are reversed). • Connect battery as required to the output of the system or turn on battery breaker. • Install remaining power modules. • On the controller, set Float and Equalize voltage to the levels specified by the battery manufacturer. • For some systems, the default setting for low AC voltage alarming is 180Vac. For nominal 120Vac operation, it is recommended to reset this value to 100Vac. • Using the controller, test the functionality of various module alarms and controls. In addition, perform a load test with the system using a resistive load box as needed. 8.4. Controller Reset - CXCi+ Soft Reset CAUTION: Before removing a CXCi+ from a live system or performing controller maintenance, and external LVD inhibit (or override) is required to avoid a disruption of service. The reset button located on the front panel of the CXCi+ is for restarting the microprocessor. When pressed momentarily, the unit beeps twice then resets. The front-panel LEDs illuminate temporarily, and then extinguish after the system has finished its 15-second self-test. CAUTION: During a reset the controller may need to run a defragmentation cycle. Cycling LEDs in the front panel indicate that defragmentation is in progress. All full defragmentation can take up to 20 minutes to perform. DO NOT power down the controller during this time. Page 34 9400021-J0 Rev B

IP Address Reset To reset the IP address, press and hold the front panel soft reset button for three seconds. The CXCi+ unit beeps three times, IP address resets to 10.10.10.201 and DHCP is disabled. The settings are saved and the unit then resets. This reset allows local access; e.g., with a laptop and a standard network cable. See current version software manual for details. Hard Reset A hard reset of the controller can be performed by pressing the front panel hard reset button. This procedure will restart the microprocessor if the front panel (soft) reset button fails to operate. CAUTION: Move the LVD control jumper to the override position before unplugging the controller. The load and batteries are still connected. Use of hard reset may cause loss of data. 8.5. Controller Reset - CXCi HP Soft Reset CAUTION: Ensure that a backup has been performed before starting this process. Use the Backup feature accessed through the LCD at Shortcuts > Backup.
