Output terminal block of the distribution unit (only for stand-alone systems) (Figure 19) 2. DC bus at rear of the shelf (Figure 20) 3. Auxiliary DC output (300W max.) on the front of each rectifier (Figure 21) 1. Terminal block with four protected DC outputs: The rectifiers are connected in parallel: • If the fuse box is empty, insert a alarm-indicating fuse (2A or 5A or 10A) in the fuse holder of the distribution unit. • Insert wires (stripping length 10mm) in the associated position in the spring cage terminal block. A flat screwdriver can be used to assist in the insertion or removal of these wires. Alarm indicating fuse Figure 19 : Front terminal block DC outputs Out 1 Out 2 Out 3 Out 4 + + + + - - - - 2. DC Bus at rear side: A load can be connected directly to the DC bus by making connections to the screw-type connector (M5 inserts), as shown in Figure 20. 0300072-J0 RevA Page 22 of 46 Figure 20 : Rear DC bus connector DC Bus + - NOTE: On delivery, the “+” pole of the DC bus is FLOATING (i.e. NOT connected to earth). In order to comply with the SELV (Safety Extra Low Voltage) rules, the “+” DC bus must be connected to earth. 3. Auxiliary DC output: Each rectifier has a front panel mounted DC output. The polarity is indicated on the front plate. Insert the wires in the mating connector and secure them by tightening the screws located on top of the connector. The mating connector can be ordered from Alpha Technologies. Figure 21 : Front Auxiliary DC output Auxiliary Output GND 0300072-J0 RevA + - Page 23 of 46 Mains input Connect the mains to the 48-300W Modular Switched Mode Rectifier System AC input according the shelf configuration. Please observe the following recommendations: • Pigtail (1.5m cable): first connect the yellow/green protective earth cable to the protective earth of the mains before connecting the neutral and line. • IEC: Insert a 3-pole IEC C15 plug only (see Figure 22) • Dual IEC: Insert two 3-pole IEC C15 plugs (see Figure 22) A complete mains cord kit can be purchased from Alpha Technologies. Each mains connection has to be protected by a 16A circuit breaker. For internal protection please refer to the specification sheet of the corresponding rectifier module. Protective earth Figure 22 : IEC mains inlet WARNING! Type of detachable mains cord: Cord used must be in compliance with table NAE.4 of CSA 60950-1/UL 60950-1, Bi-National standard, with the following characteristics: UL/CSA approved and rated 300V/90°C/1.5mm² crosssection. EMC ground If necessary for the end user system and for better EMC performance connect a ground cable to the common ground of the shelf (M4 thread at the rear side). It is also possible to use this M4 thread to ground the positive pole of the 54Vdc output. This ground is not a protective earth. Protective earth is provided by the 3-pole mains cable. Figure 23 : EMC ground 0300072-J0 RevA Page 24 of 46 Battery (only for stand-alone systems) WARNING! The batteries must be installed by qualified personnel trained in the safe use of high-energy power supplies and batteries. Refer to product safety information. WARNING! The external battery MUST be protected according to the system power and the installed cross-section of the cables. The fuse or disconnecting device must be capable of interrupting the current in the event of a short-circuit. The short-circuit current of the batteries is specified by the manufacturer. Shock hazard: all metal parts of batteries are live and so there is a danger of injury from electric shock and of accidental short circuit. Touch the battery on the insulated part only. Be careful with non-insulated tools, bracelets, watches and rings. Explosion hazard: regardless of service conditions, hydrogen gas can escape from the pressure relief valves. Installation in hermetically sealed enclosure is therefore prohibited. CAUTION! The short circuit current of the batteries must be lower than 1500A. It is recommended to place a fuse or disconnect device close to the batteries. This device must be capable of interrupting the current in the event of a short-circuit. CAUTION CAUTION! Before plugging and unplugging the battery connector, the user should pull the battery circuit breaker and check whether the LVD is non-active (open) to avoid damaging the battery connector contacts. Please also note the following: 1. Use new batteries when installing a new rectifier system. Verify they are all the same battery type with identical date codes. 2. The battery string must be 48Vdc nominal. 3. If you are making your own battery wiring harness, use up to 4mm² cables. 4. The maximum capacity of the battery is limited to 62Ah (or 1500A short-circuit current). Please observe the following procedure: 1. Number the batteries from 1 to 4 with labels or tape. 2. Coat the battery terminals with battery corrosion inhibitor. 3. Wire the batteries as shown in Figure 25. If used, install the in-line fuse. 4. Pull (open) the battery circuit breaker at the distribution unit and ensure that the LVD is open and the “LVD OK” indicator is off (Figure 25). 0300072-J0 RevA Page 25 of 46 5. Verify the battery connector polarity and DC voltage with a DC voltmeter. If correct, plug it into the battery connector at the front of the distribution unit (Figure 25). 6. Route the sensor end of the battery temperature cable to the batteries. Tape it to the side of the centre of the batteries string. As the cable terminal is voltage free, the sensor can even be placed directly on one of the copper bar inter-cell links. Insert the temperature sensor connector into the battery temperature probe socket at the front of the distribution unit (Figure 24 & Figure 25). 7. To activate the battery, push (close) the battery circuit breaker at the distribution unit and ensure that the LVD is closed (“LVD OK” LED is on) (see Figure 25). As batteries can be charged and discharged by the 48-300W Modular Switched Mode Rectifier System, the DC bus voltage and the charging current have to be defined by the MCU. The factory voltage has been set to -54.0 V at +25°C and the charging current has no limitation. When the temperature sensor is connected and activated, the temperature compensation is -3mV/K/cell. The battery disconnection voltage is fixed at 43.2V (1.8V per cell).

(Green LEDs on each rectifier should illuminate). • If the system is fitted with a Comp@s board, after 30 seconds the leftmost LED should be permanently ON Note: LED continues to flash if no Comp@s is present. If it is present, verify the display: V =~54.0 V • Close the breaker for the battery (if present). The system is then operational. Some alarms may be ON, depending of the settings on the MCU. 4.1.2 Switching OFF In order to switch off the complete system, use the external mains disconnect device. If the shelf has a battery back-up, pull the battery breaker button (the LVD will open) too. NOTE: The mains disconnect device and the battery breaker must always be easily accessible to facilitate system shut down in an emergency. In this case, the battery is disconnected from the system as the LVD is open and the load is no longer supplied by the DC Bus. 4.2 Rectifiers 300 W: CXRF 48-300W There is an LED on the rectifier front panel which illuminates in green, orange or red depending upon the status of that unit. When in fault condition, the rectifier sends an alarm signal and the LED flashes. This signal is detected by the MCU. LED Figure 27 : CXRF 48-300W 0300072-J0 RevA Page 28 of 46 Colour Pulse freq.

In the edit mode, go to the DC System tab and click on “Configuration”. Figure 28 below shows the Bus voltage screen through which setting changes can be made by entering a new value and clicking on “Modify”. It is important to note that these values will be used as references for alarms. 0300072-J0 RevA Page 31 of 46 Figure 28: Bs voltage 4.3.4 Battery Setup The battery and related alarms can be configured individually. Temperature compensation The bus voltage (and hence the battery charging voltage) can be automatically adjusted proportionate to the ambient temperature around the batteries. The value of this compensation is given by the battery manufacturer. Note that the compensation is usually given per 2V cell. As the DC Bus is 48Vdc, this value must be multiplied by 24 to obtain the figure to be set in the dedicated field of the Comp@s menu (see Figure 29 below). Figure 29 : Temperature compensation Battery String Capacity The “Battery String Capacity” is the Ah value of the installed battery blocks (see Figure 30). NOTE: You should not install a battery with a capacity greater than 62Ah. Therefore the “battery string capacity” is limited to 62Ah. Battery Charge Current Limit The maximum charging current is defined by the user. Usually the maximum charging current in Amps is one tenth of the battery capacity in Ah. Refer to the specifications of the battery and the recommendations given by the battery manufacturer. NOTE: The maximum battery current is calculated as the difference between the available rectifier current (up to 7 Amps per rectifier at 43Vdc) and the load current. The “Battery Charge Current” limit is factory pre-set to 1000 Amps. This means the batteries are not subject to a current limitation. The maximum charging current can be automatically limited by changing the setting in Comp@s. Battery Temperature The same sensor is used both to monitor battery temperature and to provide the temperature compensation reference. The battery temperature function is always active and a battery alarm is given by the MCU LED and the corresponding relay. An alarm is generated when the battery temperature reaches one of the trip levels (low or high limit). A “Battery Temperature Sensor Fail” alarm is indicated when the temperature sensor is out of range: i.e. open circuit, not connected or in short circuit. 0300072-J0 RevA Page 32 of 46 Figure 30: Battery setup Battery pre-alarms Alarms are generated when the DC Bus voltage reaches one of the pre-set alarm levels. In this case, no action is initiated other than an alarm (major, minor or battery) being generated on the MCU LEDs and the corresponding relay. 4.3.5 LVD Trip Level During a battery discharge the internal LVD opens when the battery low voltage trip level is reached. The factory settings for this are the following: Description Factory setting trip level MCU settings 43.2Vdc Factory setting delay 0 second LVD when MCU removed CLOSED Comments LVD opens when the value is reached after the time given in seconds opens at typ. 42Vdc Table 6: LVD Trip level NOTE: When the MCU is removed from the shelf (e.g. for adjustment or replacement), the LVD remains CLOSED and when the mains is absent (shelf working on the battery) the LVD will open at approximately 42 V. The LVD will re-close automatically when the mains is restored. 4.3.6 Rectifier Settings It is recommended that the minimum quantity of rectifiers needed in the system is defined in the MCU in order to generate an alarm, if one or more rectifiers are missing. Select the Edit Mode and go to the configuration tab of the DC System, change the number of rectifiers, click on “Modify” and save the new settings. The default setting is “0”. Figure 31: Remote off – Rectifiers menu 0300072-J0 RevA Page 33 of 46 If more than one rectifier is installed in the system and the load is significantly less that the full rated capacity of the installed rectifiers (e.g. load is on stand-by) the Smart Energy function can be activated in order to limit the power consumption and increase the system efficiency. The Smart Energy function turns off unused rectifiers, depending on the load activity. If a rectifier is in standby, an orange LED on its front panel will be illuminated. It is recommended that this mode of operation should only be deployed when batteries are connected to the system. To activate this function, it is necessary to change the Boolean condition in the same menu (Edit Mode – DC system – Configuration as shown in Figure 32). To avoid an unplanned activation of this function, it is recommend that a PLC should be applied relating to the battery LVD (e.g. “@(alarm17)==false”). For more details, please see the Comp@s user manual. Figure 32 : Smart Energy Boolean condition NOTE: It is important to note there is a delay of 10 seconds on the rectifier remote shut-down function. This hysteresis time is necessary in the event that the load fluctuates around a critical value. CAUTION! Please note that changes in configuration settings are only possible if the system is fitted with a Comp@s Communication Card is present in the MCU. 0300072-J0 RevA Page 34 of 46 4.3.7 Save the Configuration Once the configuration has been modified, it needs to be saved. If not, the new settings will be lost once the MCU is switched off (no DC supply). The settings are temporarily saved in the Comp@s Card until you save the data into the MCU. There are two ways to save the settings as illustrated on the screenshot: First option Second option Figure 33 : Configuration - save 0300072-J0 RevA Page 35 of 46 4.4 Alarm Monitoring 4.4.1 Factory Preset Alarm Table Table 7 contains the default alarms in the MCU.

Each alarm can also be associated to a relay. Each relay controls one LED. There are four possibilities. Here are some examples of factory preset configurations: Alarm Out Type Alarm Common NO 26 Urgent 1 or Major 9 25 Non Urgent or minor 8 24 Battery LED 3 23 4 AC fail LED 4 9 18 26 Off or Alarm R1 9 18 26 Normal R2 8 17 25 Off or Alarm R2 8 17 25 Normal R3 7 16 24 Off or Alarm R3 7 16 24 Normal R4 6 15 23 Off or Alarm R4 6 15 23 16 7 15 6 Condition R1 17 LED 2 3 Schematic 18 LED 1 2 NC Normal Table 8: Types of alarms (Front Signal Connection Card X104) A delay can also be programmed into the trigger point of each alarm.

When the test is manually started, the output of all installed rectifiers is set to deliver a low output voltage (lower than the battery voltage). The batteries are discharged by the load current. All settings are fixed and cannot be changed. The test time and the end test voltage are fixed at 10 minutes and 46Vdc but the battery current is determined by the load. The table below lists all the actions for conducting this type of battery test: Status Start Continuity Test Stop Continuity Test Reset Alarm Conditions End voltage reached Test time reached Actions Battery Test pressed >10” Automatic Comments Manual start Test time of 10 minutes not reached Automatic Manual Manual Indications Battery Alarm No Alarm Battery Test pressed >5” Perform a short Battery Test and cancel it No Alarm Table 9: Battery Continuity Test 0300072-J0 RevA Page 38 of 46 4.4.3.2 BATTERY TEST NOTE: The Battery License is required to perform a full battery test. The battery test starts when: • the time period between two automatic tests is reached (see Comp@s user manual for more details) OR • the “BATT TEST” button is pressed for a period of more than 5 seconds. During the test, the green “LVD ON” LED flashes. The battery test cannot start when: • an alarm is present • the batteries are charging or discharging • the mains is absent NOTE: The delay between two tests is set as 180 days. It starts: • after an automatic test • after each manual test • after stopping a manual test • when the MCU is inserted into the shelf • each time the whole system, including the MCU, is switched ON When the test is started (manually or automatically after 180 days), all installed rectifiers are set to deliver a low output voltage (lower than the battery voltage). The batteries are discharged at a fixed current which can be set by the user. The difference between the load current and the battery current is supplied by the rectifiers (the rectifiers keep the battery discharge current stable in case of load variations during the test). The discharge current and the battery voltage are measured and integrated. As the battery discharging current is always the same, the discharge curves from different discharge tests can easily be compared. The battery test terminates when: • the programmed power (30% to 50% of the nominal battery Ah value) is extracted before the end voltage (44V or 46V) • the end voltage is reached OR • the “BATT TEST” button is pressed. The batteries are discharged until 30% (user settable) of their nominal capacity has been extracted. The nominal capacity of the batteries is a variable set by the user via Comp@s. The battery test settings can be modified via the dedicated Comp@s page, as shown in Figure 35 . 0300072-J0 RevA Page 39 of 46 Figure 35: Comp@s - Battery test Table 10 lists the actions for conducting a battery test: Status Conditions Start Battery Test Actions Test Time Interval reached Battery test button pressed more than 5sec.
