Installation & Commissioning, Operation & Maintenance Manual
WARNINGS
Communications Grade valve regulated gas recombination lead acid cells and monoblocs are electrically live at all times and must be treated with care. The products are generally capable of supplying high short circuit currents even if the case or lid is damaged. Remember that the battery is electrically live at all times and cannot be isolated in the conventional sense, although the voltage at any point can be reduced by removal of appropriate inter battery links. Take care that short circuits are not caused by accidentally dropping or touching metal objects onto the cell or monoblocs terminals.
Before connecting batteries and cables remove all metallic objects such as rings, watches etc from your hands and wrists to avoid causing a short circuit.
Do not smoke or permit open flames near batteries. Avoid any activity near the batteries that may cause sparks.
If the rectifier module is damaged in any way or develops a fault it should be replaced immediately. This should only be done by appropriately qualified personnel. Refer to the operations manual for instructions.
The equipment contains voltages that may be lethal. The AC distribution front cover plate should not be removed without first isolating the AC supplies. AC supply connection should only be done by appropriately qualified personnel.
Allow for adequate ventilation around the units. A 5 –10 mm clearance should be kept between the batteries as they may expand in high temperatures.
Be aware that the rectifier is rated for high temperature operations. Therefore care must be taken when handling the modules as they can reach temperatures of 60oC

UNPACKING
All equipment is suitable for being moved with a normal pallet truck whilst packed. When unpacked, cabinets may weigh 145kg and are heavier at the top end of the cabinet.
CAUTION: THESE UNITS ARE TOP HEAVY, AND CAN TIP OVER UNEXPECTEDLY IF NOT HANDLED WITH CARE. Appropriate lifting equipment should be used, and suitable care must be taken while handling these units. The most appropriate method of moving the racks is with the use of a hand trolley. Some packaging material should be placed between the trolley and the rack to avoid damage to the rack. It is however recommended that the complete boxes be positioned as close as possible to the actual location where the system is to be installed.
If lifting using eye bolts, a spreader bar must be used.

EARTH CABLING
Each cabinet should be bound to earth using links. There is one 95mm² earth cable shipped with each cabinet (Except SP18-RRU system). Ensure this converter cubicle bond is bonding the cabinet M8 bolt to the positive common bar (SPC) inside the cabinet. Also ensure flat and spring washers are used and the links are secure. External earthing should be done to relevant company standards. Also connect the battery extension cabinet, if being used, to the SPC inside the rectifier cabinet with the 95mm² earth cable supplied with the extension cabinet. There is also a M6 bolt that is connected to the protective earth on the AC input terminals that needs no further connections .

CONNECTING THE BATTERIES
The FlatPack2 system is supplied with a 100A battery circuit breaker with auxiliary for each string. The battery CB’s are located on the left-hand side of each battery shelf. System is supplied with cables from the battery CB’s to the battery trays already fitted. Ensure that the battery CB’s are turned OFF before connecting the batteries. NOTE: For battery shelves not being used, ensure cable ends remain insulated with heat shrink provided. Installation Steps 1. Before commencing the installation, ensure that each battery is in good condition and has not been damaged during transport. 2. Monoblocs are heavy; and accordingly the recommended lifting equipment should be used. 3. Remove retaining strap. 4. Position the batteries on shelves as per fig 10.1. We suggest that one monobloc be lifted into place at a time. Leave a clearance space of between 5 – 10 mm between the batteries. Slide the batteries gently back to the rear of the system to avoid any risk of damaging them on the rear of the shelf. 5. Particular care should be taken when placing on the shelves to ensure the correct positioning of the +ve and –ve terminals. 6. Connect inter battery flexible cables and inter tier links. To ensure a low resistance joint clean the flat contact making surfaces of the terminal posts and connectors with a soft clean cloth. The links do not normally require cleaning and can be fitted without any operation. However in some cases the links could show encrustation and this should be removed using Scotchbrite or fine grade abrasive paper. Do not use a wire brush and be especially careful not to break through the lead plating. Apply a light coating of grease to the contact – mating surfaces and place a solid connector strap or flexible link in position. Tighten the nuts firmly: 7-8 Nm for a Stud type terminal; (12FIT100 [M6], SBS190 [M6]), 8-10 Nm for a socket type terminal (12FFT100 [M8]) using an insulated torque wrench. (A non-torque insulated wrench is supplied with the batteries. This should be used only when the installer is familiar with battery installations and knows from experience what level of torque needs to be applied) Lightly smear grease on the washer and nut. WARNING: Particular care should be taken to ensure the batteries are not shortcircuited during this procedure. 7. Place terminal boots and battery link caps on all battery terminals. 8. Place the battery numbering labels in place starting at the first battery (on the bottom shelf) and working to the last. Replace the battery 9. Wait 24 Hours and re-torque the battery terminals. You will find the following colour coding on the battery cables. Blue (–) negative and Red (+) Positive
The system must not be located in an explosive atmosphere, i.e. in the presence of flammable gases and fumes. Suitable ventilation for the battery must be provided.

EXPANSION RACK ALARM CONFIGURATION
The battery alarms provide signals to the Smartpack control module via auxiliary switch’s on each battery circuit breaker. The purpose of this signal is to initiate an alarm condition if the battery CB has tripped. This a normally closed loop which if broken, will create an alarm Alarm Interconnection cables Each system cabinet is supplied with an alarm interconnection cable that connects the system cabinet to the expansion battery cabinet. The alarm interconnection cable is a 2000mm long, 2 way cable. Installation Steps for Expansion Cabinet alarm wiring There is a four way terminal block fitted in the rectifier cabinet on the LHS under the distribution. When an external battery cabinet has been installed remove the link wire on the top of the terminals:1. Connect one end of the 2 core alarm interconnection cable to the two terminals located in the top LHS of the cabinet. 2. Run the cable through the top cover of the cabinet to the terminal block located in the top of the battery cabinet. 3. Secure the alarm cable wiring with cable ties.

INSTALATION & REFRESHING VOLTAGES OF BATTERIES
If the batteries are in service on a temperature compensated power supply in temperatures above an ambient of 20°C, the service life of the battery will be affected. See table 13.1 below. Ambient temperature (deg C) 20 25 30 35 40 45 50
Expected life (% of nominal) 100 70 50 35 25 18 15
Table 13.1
To check if a refresh is needed, follow the below procedure. 1. Check the open circuit voltage of each battery. The minimum monobloc open circuit voltage that the battery can be considered as not requiring refresh is 12.72V. Any monoblocs that are below this voltage will have to be refreshed as below. Above this value, they may be considered acceptable for use & do not need to be refreshed. 2. Put the batteries on a float voltage charge of 54.48V for a period of 48 hours at 20degC. 3. After float charging leave the batteries to settle for a further 48 hours. 4. Check the open circuit voltages of the monoblocs. The minimum monobloc open circuit voltage after refresh is 12.72V. Any monoblocs that are below this voltage cannot be considered as serviceable.

INSTALLATION AND OPERATION OF RECTIFIER MODULES
If for any reason any of the rectifiers have to be removed, or additional rectifiers are being fitted, please refer to the following procedure. See also section 25, for important information regarding rectifier operation and positioning. It is to be noted that the FlatPack2 rectifier module is a “Hot” plug rectifier allowing expandability and serviceability without power shutdown. The current share functionality of the modules ensures all modules deliver the same amount of current. The FlatPack2 rectifier cabinet accommodates up to 9 rectifier modules. Installing rectifiers 1. Unpack the rectifier modules from their packaging. 2. Refer to section 15.3: for information regarding the correct rectifier positioning. 3. With the system on, slide each module into place, but do not push the rectifier all the way home at this point. Make sure the pull out handles have been released as shown in figs 15.1 and 15.2 below, then push the unit into place and lock the rectifier into position by pushing the handles firmly into their housing. Hole to release the handles spring mechanism
Handle in locked position
Fig. 15.1 To remove a rectifier, follow the steps below: 1. Unlock and release the handles by inserting a small screw driver into the holes in the upper corners of the rectifier front panel and carefully push it downwards. The handle will release and pop out.
Handle in unlocked position

15.2 Plugging in Rectifiers When a rectifier is hot plugged in a power shelf for the first time, the Smartpack controller assigns the next available ID number to the rectifier, starting with “01”. This ID number (or CAN bus address) and the rectifier’s serial number are stored in both SmartPack and Rectifier modules. When a previously installed (hot plugged) Flatpack2 rectifier is inserted in a power shelf, the Smartpack controller “recognizes” the module, and assigns the same ID to the rectifier. In other words, the controller and the rectifier “remember” the assigned ID and serial numbers, even after removing and reinserting the rectifier in the shelf. To achieve a more controlled ID assignment, you should always insert & hot-plug new Flatpack2 rectifiers in the power shelves, one module at a time, starting with shelf position 1, 2, 3 and so on.
During continuous operation, the metal case of the rectifier unit can become hot. There is no danger of contact burns occurring, but all care should still be taken when handling recently unplugged rectifiers.
15.3 Identification of different rated rectifiers Three different types of Flatpack2 rectifiers are compatible these systems; a 1.8kW rectifier & a 2.0kW rectifier and a 2.0kW HE rectifier. These interoperate fully, including alarms & current sharing (current sharing is by a percentage of total output). The only functional difference between the 1.8kW and 2.0kW rectifiers is their maximum power output. For easy identification, the 1.8kW rectifier has a silver front, the 2kW rectifier has a light blue front and 2kW HE rectifier has a black front. HE and 2000W label

15.4 Replacing and installing rectifier modules
If a upgrading a system with additional rectifiers: Place the new rectifiers into the next highest rectifier position, in order. See table below. Their existence will be automatically logged by the controller, no further configuration is required.
If a replacing a faulty rectifier and a replacement rectifier is immediately available: 1. Unclip handles of faulty rectifier as shown above and pull out rectifier. 2. Fit the new rectifier into the position left by the faulty rectifier. 3. Eliminate any rectifier alarm by performing a ‘rectifier recount’ [rectifier reset, under rectifier info] that resets the number of rectifiers using the front keypad, under user menu (see section 17.3)
If a replacing a faulty rectifier and a replacement rectifier is not immediately available: 1. Unclip handles of faulty rectifier as shown above and pull out rectifier. 2. Remove the highest ID rectifier (important) and fit into the vacant faulty rectifier position, in order to maintain continuity. 3. Eliminate any rectifier alarm by performing a ‘rectifier recount’ [rectifier reset, under rectifier info] that resets the number of rectifiers using the front keypad, under user menu (see section 17.3) NOTE: The highest ID rectifier is now reassigned to the ID of the faulty rectifier in the system 4. When a new rectifier is obtained, fit it into the highest vacant ID position. Its existence will be automatically logged by the controller (as in the above scenario, ‘upgrading a system with additional rectifiers’.)

INSTALLING AND REMOVING THE SMARTPACK CONTROLLER (ETHERNET CONNECTION) The Smartpack controller is physically held in place using similar method as the Flatpack2 rectifiers: It incorporates handles that serve both to lock the module into position and to pull it out of its housing. CAUTION: Do not hand-carry the controller by its handles. Cables are plugged to the controller’s rear panel. If in the event that the Smartpack needs to be removed for any reason the following procedure should be used: 1. Release the handles (using similar method as the Flatpack2 rectifiers as described above) 2. Grasp the Smartpack by the handles at either side of the unit and pull the unit out. The connection cables are attached to the rear of the controller via several ‘D’ type connectors. Pull out the controller enough to access the rear of the unit, and unplug the cables as detailed over page. NOTE: make a record of which positions the connectors were removed from for future reference.
Open the handles before inserting the controller into the power shelf. To refit the Smartpack: 1. Carefully reconnect the cables to the appropriate positions in the rear of the controller. 2. Slide the controller unit into place making sure that all cables are not overly bent. 3. Fasten the unit by firmly pushing the handles into their housing. Removing the Smartpack controller
Open the handles (insert a screwdriver into the holes to release the spring mechanism) Remove the module
Use both handles to pull the module gently loose; support it from underneath; hidden cables are connected to the rear panel.

Input 1: Generator input (Disabled). When operating on AC mains, the digital input is left open, (its normal state.) If this input is closed (shorted), the controller will assume that it is now operating from a generator. The controller will then limit the battery charge current down to a small value in order to limit the strain introduced on the generator. In this way, the generator can be used to supply only the load, and not be burdened by also trying to recharge discharged batteries at the same time.
Input 2: Off normal input (Disabled). When in a normal state the digital input is left open. If this input is closed (shorted), the controller will extend an off normal alarm on the alarm relay output (relay 6.), This could be used in combination with a switch to indicate someone is on site. Input 3: Spare Connection. Input 4: Load MCB fail alarm. When a load MCB is in the off position and alarm will be generated and sent to the Smartpack which will change the state for relay #4.

Input 1: Generator input. When operating on AC mains, the digital input is left open, (its normal state.) If this input is closed (shorted), the controller will assume that it is now operating from a generator. The controller will then limit the battery charge current down to a small value in order to limit the strain introduced on the generator. In this way, the generator can be used to supply only the load, and not be burdened by also trying to recharge discharged batteries at the same time. Input 2: Off normal input. When in a normal state the digital input is left open. If this input is closed (shorted), the controller will extend an off normal alarm on the alarm relay output (relay 6.)

19. +24 V DC/DC CONVERTER The Flatpack DC/DC 48/24, a modular hot plug-in DC/DC converter.
Fig 19.1 A DC/DC converter module The converter is specially designed to provide a high quality and highly reliable DC output voltage. The module has a soft start power-up and an internal blocking diode allows hot plug-in and isolates any faults in the converter output from the DC bus. Several internal protection circuits ensure safe operation, even outside specified limits for normal operation.. A module failure alarm is given if the module shuts down due to high output voltage, or in case of an internal failure. Converters connected in parallel will exhibit active load sharing via CAN bus. Front LEDs show power ON/OFF and alarm status in addition to a LED bar graph for output current indication. The Flatpack DC/DC 48/24 will operate in ambient temperatures up to +75°C (+167°F). At temperatures above +65°C the output power may be derated. This unit has the part number: 241114.503, and is only included in SEF29-X-156 systems . The output of the 24V DC/DC converter is found on top if the cabinet, via a 175A red Anderson connection. The 24V output of the SEF29-X-156 systems are floating. That is, to achieve a non floating +24V output with respect to the -48V output, the negative of the DC/DC converter will need to be brought back to the common positive bar inside the distribution at the top of the cabinet. The alarms extended from the DC/DC converter are to be found on a labeled terminal block inside the -48V distribution area.
See the attachments for more data regarding the DC/DC Converter.

AC MAIN SUPPLY INSTALLATION
AC mains connection terminals are provided for the AC mains connection. The terminals are pre-connected to the rectifier modules. Cables of up to 10mm2 size can be connected to these terminals. Termination or configuration of the AC Mains connection is only to be performed by a licensed electrical installer. When connecting power to this system, a nearby AC mains disconnect device should be integrated into the circuit to facilitate servicing. This could be an isolating switch, circuit breaker or equivalent device. Phase distribution on rectifiers The system is pre-wired to suit a 3-phase +N and Earth AC supply. Other configurations are possible, see above. The phase distribution for the rectifiers is shown below. While installing the rectifiers please ensure that they are distributed evenly between phases to ensure a balanced load on each phase where possible.

DC DISTRIBUTION INSTALLATION
The FlatPack2 System is equipped with a 24-way distribution module fitted at the top of the cabinet. The circuit breakers that can be fitted on the standard comb bus are 6x 80-125A (27mm pitch) + up to 18x 1-63A standard width (18mm pitch) type. The common terminal bar is located behind the load circuit breakers and is accessible by removing the top cover. Note: -48V will be present on the output terminals of the MCB’s even when in the off position and no load is connected, due to MCB monitoring. There is no risk to personnel from this voltage. The current available from the source for the fuse fail diode matrix (through the reverse biased diode) at short circuit using a 20MOhm multimeter= 0.0052A when direct connection is made to the cathode of the sensing diodes. This can be considered a safe level.
When installing DC load cables, be aware of the position of the AC input terminal block, behind the positive common bar. The circuit breakers are arranged from left to right as: Position # from left 1 2 3

Load Cable Installation Considerations Consideration should be given to the entry arrangement of load cables to ensure easy installation of additional load cables when the system is operating. Ensure protective edging is fitted to any sharp edges over which cables pass. Ensure cables are suitably supported by a cross beam, making sure not to over stress the common positive bar and circuit breakers. 22.
TEMPERATURE COMPENSATION
The system is supplied with a temperature-sensing probe for temperature compensation charging. The temperature compensation cable is temporarily cabled tied to the system. The cable should be carefully untied and the transistor probe should be placed in the middle of the battery string(s) for measurement of air temperature as close as possible to the batteries. Do not rest the probe directly against any of the batteries as this will give a false reading in the event of that individual battery having a fault.
Fig 22.1 Temperature probe deployment should be near, but not touching, the middle string of batteries.

2. The voltage alarms can be tested using any method in which the system voltage can be varied, or the alarm setting can be adjusted. Two methods are listed here. Refer to table 18.1 for relay outputs:
External Power Supply Method
ISOLATE THE BATTERIES FROM THE SYSTEM AND CONNECT A 0-60VDC EXTERNAL POWER SUPPLY TO THE OUTPUT BARS. ENSURE THE CORRECT POLARITY WHEN CONNECTING!
Once the mains to the system is turned off, the controller will display the output voltage of the external power supply. The power supply can then be adjusted to activate the various high and low voltage alarms. This method will have a constant mains alarm as well as the alarms being tested. Adjusting Alarm Activation Level Method Connect a PC/laptop to the Smartpack controller and run the latest version of Powersuite. Note: Once each of the alarms (below) have been tested, ensure you change their alarm levels back to their original values. Each alarm is to be tested, one at a time.
To test High Battery Alarm 1 (High Float), change its value to at least 0.5V below the system voltage. This will activate an alarm on the display and at the alarm PCB. Using a Continuity Tester, check the operation of the N/O N/C relays at the alarm PCB. To test High Battery Alarm 2 (High Load), change its value to at least 0.5V below the system voltage. This will activate an alarm on the display and at the alarm PCB. Using a Continuity Tester, check the operation of the N/O N/C relays at the alarm PCB. To test Low Battery Alarm 1 (Low Float), change its value to at least 0.5V above the system voltage. This will activate an alarm on the display and at the alarm PCB. Using a Continuity Tester, check the operation of the N/O N/C relays at the alarm PCB. To test Low Battery Alarm 2 (Low Load), change its value to at least 0.5V above the system voltage. This will activate an alarm on the display and at the alarm PCB. Using a Continuity Tester, check the operation of the N/O N/C relays at the alarm PCB. 3. Off Normal This alarm indicates that a battery test initiated by a PC is in progress, and can be tested using a PC and the Powersuite software.
Alternatively, short pins 3 & 4 on TB1 to create an off normal ( see section 18.2 Digital inputs) 4. Rectifier Fail Ensure the rectifier is off then insert a plastic object into the fan of the rectifier. Turn ON rectifier; this should give a rectifier fail alarm. Using a Continuity Tester, check the operation of the N/O N/C relays at the alarm PCB. The fan should never be stopped by inserting an object into it while running, as this could damage the fan. TG6206M MAN I&C + O&M Manual 149 150 156, A111171.000, A112040.000 and A112041.000 FlatPack2 systems

Installation & Commissioning, Operation & Maintenance Manual
5. Load Fuse Turn off one of the load circuit breakers. (Note: The CB must be connected to a load). This will activate an Alarm on the Display and at the alarm PCB. Using a Continuity Tester check the operation of the N/O N/C relays at the alarm PCB.
6. Battery Fuse NOTE: All battery CB’s have to be ON for there to be NO Battery fuse alarm. Ensure all vacant battery shelves have heatshrink on their loose cables When the Battery is connected, simply switch off one Battery circuit breaker. This will activate an Alarm on the Display and at the alarm PCB. Using a Continuity Tester, check the operation of the N/O N/C relays at the alarm PCB.
7. Monitor Fail: Unlock and release the handles of the SmartPack alarm module by inserting a small screw driver into the holes in the upper corners of the front panel and carefully push it downwards. The handle will release and pop out. Remove CON5 from the rear on the Smartpack controller. This will activate the Monitor Fail Alarm. Using a Continuity Tester, check the operation of the N/O N/C relays at the Monitor Fail PCB.
8. DCDC Converter Fail. Ensure the Converter is off then insert a plastic object into the fan of the rectifier. Turn ON converter; this should give a converter fail alarm. Using a Continuity Tester, check the operation of the N/O N/C relays at the converter alarm PCB. The fan should never be stopped by inserting an object into it while running, as this could damage the fan. The DCDC converter alarm terminal block is located to the left of the cabinet below the monitor fail alarm, and is mounted with the battery expansion alarm extension. See section 18.
