9 Planning usage Scope of delivery All materials are packaged and sent out together with a delivery note and AWA. 2.2 Receiving goods Check that the material and documentation received corresponds to the scope of your installation project. Check the components supplied and ensure that they function as intended and correspond with the information on the documentation. Take particular note of the information on the packaging (symbols, labels, etc.). Observe the warning notices. When ordering a system, you can determine the element's installation location in the layout on the basis of the item number on the packaging and in the project manual. Check that the material has been delivered in perfect condition and with no transport damage. Use only material that is in a perfect condition. 2.3 Safe handling Handling material NOTICE As with all electrical equipment, this material should be handled with care, following the instructions listed here. Proceed with caution and pay attention to personnel safety. Use all equipment necessary for correct handling of the material. Installation Manual, 02/2011, A5E

10 Planning usage 2.4 Storage 2.4 Storage 1. The material storage area has to meet the following requirements: It must be stable, secure and not on a slope. It must be protected against damp, extreme temperatures and water penetration. Effective protection against dust, water, welding sparks and other factors that could damage the material supplied must be in place. For safety reasons, the area must not serve as a gangway, nor must it be used to assemble other equipment. 2. Take note of the specific storage and packaging information featured on the packaging (symbols, labels, etc.). 3. If possible, store the material in its transport packaging. As a rule, the elements are supplied on pallets that must not be stacked on top of one another. If the transport packaging is removed, store the elements in their product packaging as follows: Tap-off units, junction units, flanged ends and cable feeder units must not be stacked. Straight trunking units: Depending on the system, you can only stack a specific number of elements flat on top of one another: BD2 aluminium system BD2 copper system A 10 elements, max A 5 elements, max A 5 elements, max A 3 elements, max. Figure 2-1 Storing trunking units 8 Installation Manual, 02/2011, A5E

11 Planning usage 2.5 Packaging 2.5 Packaging The busbar trunking system elements are supplied with protective covers on their ends These protect conductors, insulators and joint blocks against impact during transport and storage on the building site. The protective foil/packaging also protects the elements from dust and damp. NOTICE Do not remove the protective covers until the busbar trunking system elements are ready to be joined. Do not remove all the protective coverings until you install the elements. Be very careful when removing the strap retainers. The sharp edges on the strap retainers pose a significant risk of injury when they spring off. Note The protective material can be recycled. When disposing of it, refer to the applicable standards for waste disposal in the installation area. 2.6 Handling Handling Busbar trunking system elements can be moved using a forklift and/or suspended from slings. Figure 2-2 Transport using a forklift Installation Manual, 02/2011, A5E

12 Planning usage 2.6 Handling Suspension from slings Ensure that the elements do not get damaged when transporting them with a forklift. Use fabric slings to suspend the busbar trunking system elements. As a rule, always attach slings to lift the elements. NOTICE Never use abrasive or metal slings under any circumstances. Never suspend the elements by their conductors, as this could potentially damage them beyond repair. 10 Installation Manual, 02/2011, A5E

13 Installation Overview 1. Checking elements: Inspect all elements on receipt and ensure that neither the conductors nor their insulation have been damaged during handling and/or storage. 2. Correct installation sequence: Install the elements in accordance with the planned layout as indicated in the installation drawings. 3. Connecting elements: Ensure that the spacing between adjoining elements is correct. Establish the electrical connection between the conductors; do not place the covers on the junction yet (see Connecting units (Page 22)). 4. Checking the assembled elements: Check the insulation resistance of the layout. No other equipment (tap-off units, end feed units, etc.) must be connected at this time. (see chapter Commissioning (Page 35)). 5. Closing the junctions: Place the covers on the mechanical junctions (see Connecting units (Page 22)). DANGER All installation work on the busbar layout must be done before electrifying the system. Installation Manual, 02/2011, A5E

16 Installation 3.3 Installation recommendations 3.3 Installation recommendations Installation recommendations Install either the whole line or parts of it, depending on how accessible and safe the layout is. 1. Start the installation by connecting the board outlets. 2. Once the distribution board has been installed, continue towards the sub-distribution board and consumers. 3. For vertical installation, use the joint block of the top trunking unit for the feeder unit. When the vertical laying mode is used, a certain installation position must be kept to. The PE must always be on the right and the side with the joint block of the trunking unit must point upwards. This ensures that the flange cover is fitted onto the terminal from the front and the screws can be tightened, the tap-off units are not fitted in the forbidden head position. To simplify handling, on runs between feeder units the last element to be inserted should be a straight trunking unit. If the run ends with an end cap, fit this last. NOTICE Protect all elements from adverse ambient conditions and other potentially damaging agents until installation has been completed. Always pay attention to the safety of personnel and ensure that material does not get damaged. Note Deviating from the recommendations These installation recommendations specify the general assembly sequence for the various busbar trunking system elements. As local conditions on the building site or within a project can vary, deviations from these recommendations are possible. In such cases, please get in touch with your SIEMENS contact. 14 Installation Manual, 02/2011, A5E

29 Installation 3.6 Expansion unit 3.6 Expansion unit The BD2 system does not require an additional expansion unit. The system design ensures expansion compensation through the joint block. Note The movements of the building and the fixing structures are not compensated by the BD2 system. 3.7 Flanged end Flanged end The flanged end connects the busbar trunking system to external power supplies or outputs, both mechanically and electrically. These external power supplies are usually distribution boards for low-voltage main distribution systems. Figure 3-10 Flanged end Installation Preparing the non-siemens distribution board for the connection of the flanged end 1. Align the distribution board mounting surface so that it is flat. 2. Prepare the cutouts in accordance with the AWA. 3. Reinforce the distribution board mounting surface in accordance with the weight of the flanged end. 4. The distribution board must contain fixtures for mechanically securing the flanged end. The flanged end's own weight must be mechanically decoupled from the electrical connection (copper connection). 5. During this process, observe the flanged end connection dimensions and cross-section specifications, as well as the distribution board manufacturer's specifications. 6. When connecting 5-core cables, remove the link between PE and N. Installation Manual, 02/2011, A5E

30 Installation 3.7 Flanged end Installing the flanged end in the distribution board Following storage and transport to the installation location, you must first mechanically secure the flanged end in the distribution board. After that, you electrically connect the flanged end to the busbars or the circuit breaker. Securing the flanged end mechanically 1. The power cables of the BD2...-VE must be mechanically fixed in the distribution board. The BD2...-VE busbars must not be subjected to any additional forces. 2. Attach the flanged end to the distribution board enclosure. Observe the distribution board specifications relating to the degree of protection. It may be necessary to use additional sealant in order to achieve degrees of protection higher than IP 55. Connecting the flanged end electrically 1. Remove the protective transportation devices. 2. Perform the electrical connection in accordance with the flanged end specifications (minimum cross-sections) and the information provided by the distribution board manufacturer. Dimension the connecting material in accordance with these specifications. Note You must comply with the required minimum cross-sections for the flanged end, otherwise the maximum permissible limit temperature of 130 C cannot be guaranteed. The design of the electrical connection determines the short circuit strength. The designer, usually the distribution board manufacturer or constructor, is responsible for the temperature and short circuit strength of the electrical connection. 28 Installation Manual, 02/2011, A5E

31 Installation 3.8 Cable feeder units 3.8 Cable feeder units Various feeder units are available to supply the busbar trunking system, depending on the requirements. End feeder units connect the system to external power sources at the ends, and centre feeder units connect the system within the run. Phase sequence can be changed on-site by rotating the distribution connection piece or the busbar package. Establish the mechanical and electrical connections as described in the section entitled "Joining elements". Note Short-circuit and overload protection When a centre feeder unit is used, the left and right runs of the busbar trunking system are supplied with power simultaneously. In this case, you must ensure that the loads are protected against short circuits, either via an upstream protective device or by additional protective measures, and an overload is avoided. Installation Manual, 02/2011, A5E

32 Installation 3.9 Fire barrier 3.9 Fire barrier Fire barrier regulations If the busbar run passes through a fire wall or ceiling, you must provide the run with a fire barrier. It is not permissible to mount the fire barrier via the junction (joint block). Note Depending on country-specific regulations, it may be necessary to attach additional fire barrier notices directly at the installation site. Fire barrier signs required directly at the installation site Installing a fire barrier The following conditions must be met in order for the fire barrier to be installed (also see illustration): The internal fire barrier must be positioned in the centre of the wall or ceiling. Figure 3-11 Internal fire barrier (left), internal and external fire barrier (right) 30 Installation Manual, 02/2011, A5E

33 Installation 3.9 Fire barrier Besides positioning, the following points must also be observed with regard to installation of the trunking units with fire protection: In the case of horizontal installation, the busbar run must be supported with a fixing bracket at a distance of about 500 mm before and after the component. The opening (1) between the busbar trunking element and the component must be filled with mineral mortar or ZZ fire barrier sealant TS90. The gaps between PROMATECT-H(L) plates and the busbar trunking element as well as the structural part must be closed with ZZ fire barrier sealant TS90 (included in scope of supply, if plates are required). The mortar or the ZZ fire barrier sealant TS90 must comply with the applicable regulations for producing the fire resistance class or the wall or ceiling. The trunking units must be installed by a firm approved for fire protection technology. In Germany, the fire protection approval kit BD-2S90-ZUL-D or BD2-120-ZUL-D is required. PROMATECT-H/L 2x (2x 6) = 24x PZ2 ZZ Figure 3-12 Installing fire protection Installation Manual, 02/2011, A5E

34 Installation 3.10 Tap-off unit 3.10 Tap-off unit Tap-off units from 10 A to 530 A 1. These tap-off units are positioned at the tap-off points on the trunking. Power is tapped via the tap-off point. Depending on the relevant national regulations for electrical installations, these tap-off units may either be mounted when live, or this may not be permissible. If the latter is the case, switch the voltage off and safeguard the run against restart in accordance with onsite regulations. Tap-off units for 250 A or higher are fastened with an included mounting aid. 2. See the relevant AWA for more details and instructions on mounting tap-off units. Note You must check the necessary space requirements prior to mounting. These tap-off units cannot be positioned at junctions above a joint block. The necessary space requirements must be taken into account during the project design stage.

37 Commissioning Steps to be performed prior to electrification of the line Steps to be performed prior to electrification of the line WARNING Live electrical equipment can cause personal injury or even death. Therefore, proceed with extreme caution and follow these instructions carefully. 1. Insulate the busbar trunking system from the connections to transformers, switches, meters, etc. 2. Check that all connections are fully tightened. Follow the instructions relating to tightening torques (visual inspection with record of results). 3. Check all suspension and fixing elements. All the fixing studs and screws of the fixing brackets must be tightened. 4. Make sure that all tap-off units and tapping equipment is disconnected (OFF). 5. Carry out an insulation resistance test to make sure that there are no short circuits or earth failures in the system (phase - earth, phase - neutral and phase - phase). You will observe that the readings vary depending on the length of the run, the number and size of the conductors and the level of moisture in the atmosphere. Record the measured values in an insulation test report. If you obtain readings lower than 1 MΩ per 100 m (1 MΩ x 100/length of run in metres), please contact technical support. As a rule, you must comply with the relevant countryspecific regulations (in Germany, this is a minimum of 0.5 MΩ). 6. Check that the poles on the busbar trunking system and those on the transformers, switches, meters, etc. correspond correctly on electrification. Installation Manual, 02/2011, A5E

38 Commissioning 4.2 Electrifying the line 4.2 Electrifying the line Electrifying the line WARNING Live electrical equipment can cause personal injury or even death. The first time that the busbar trunking system conductors are electrified can be dangerous. Therefore, you must follow these instructions to the letter, along with the relevant applicable country-specific regulations. 1. Qualified personnel must be present the first time the line is electrified. If short circuits or earth failures caused by incorrect installation have not been previously detected, this can lead to serious consequences once voltage is applied. 2. There must be no electrical load connected to the busbar trunking system when it is electrified; the entire system must be checked to ensure that this is the case. 3. You must electrify the line step by step, starting at the power supply and moving towards the loads at the end. The principal elements must be electrified first, followed by the feed equipment and, finally, the secondary element circuits. You must act with purpose and conviction when activating the line. 4. Once the line has been connected, consumers such as lights, contactors, heaters and motors can be switched on. 5. Faults caused by short circuits must trigger the protective device for the feeder unit in the manner prescribed by the official regulations. You must ensure that the system is deenergised before you eliminate the cause of the fault. Observe the five safety rules: 1. Disconnect; 2. Safeguard against restart; 3. Ensure the system is de-energised; 4. Earth and short circuit; 5. Cover and safeguard neighbouring live parts. 36 Installation Manual, 02/2011, A5E

39 Service and maintenance Inspections/Expansions Expansions As a flexible power distribution board, the BD2 busbar trunking system can in principle adapt to meet local needs in terms of loads and can also be expanded for new loads. As a first stage it can be sufficient simply to plug existing or new tap-off units into existing, unused tap-off points. If there are no more tap-off points available or if certain buildings/areas are not supplied by the BD2, it is necessary in a second stage to extend the BD2 run with appropriate trunking units. 5.2 Service and maintenance The BD2 busbar trunking system is maintenance-free as long as the following conditions are met: Assembly was performed in line with the valid guidelines as per AWA and the installation manual. Commissioning was performed correctly and then checked and logged with insulation measurements and visual inspections. There are no extreme mechanical loads due to external forces or significant impairment due to foreign bodies or dust. There are no extreme stresses/loads due to water or liquids (observe the degree of protection). No exposure to aggressive media (acids, etc.).
