Introduction 1This manual is designed to assist you in installing, maintaining, and commissioning BD2 systems.

Note Before installing the system on the site, you must read and follow the instructions on storage, transport and handling.

WARNING

Only personnel who have been trained in site safety regulations (such as the wearing of helmets, safety goggles, safety shoes, high-visibility tabards, etc.) may work on construction sites and install busbar trunking systems. The responsible safety officer must provide mandatory safety training.

Manual overview This manual consists of four sections: ● General information: Brief overview of busbar trunking system components and how they

are installed ● Installation: Description of how the busbar trunking system elements are installed ● Inspection, expansions, checks: Description of how to handle the busbar trunking system

once it has been installed ● Checklists and reports You can find more detailed technical information on BD2 systems in the planning manual "Planning with SIVACON 8PS" (order number A5E01541101-01) and in Catalogue LV 70. In addition, observe the installation operating instructions (AWA) for the individual busbar elements. These contain specific details on how to install the various busbar elements. You can find an overview of the AWAs at Installing a busbar run (Page 11)

Introduction



Planning usage 22.1 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. ● The item number on the packaging and the project manual will help you to identify where

the element is to be installed in the layout. ● Check that the material has been delivered in perfect condition and with no transport

damage.

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.

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:

160 to 400 A 10 elements, max. BD2 aluminium system 630 to 1000 A 5 elements, max. 160 to 400 A 5 elements, max. BD2 copper system 630 to 1250 A 3 elements, max.

Figure 2-1 Storing trunking units

Planning usage 2.5 Packaging


NOTICE Do not remove the protective covers from the ends of the busbar trunking until the electrical connection has been made, otherwise material may be damaged and functioning may be impaired following installation.

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

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. The elements are supplied with special parts for securing the slings in place and for supporting their own weight. The suspended elements can be removed and placed in various positions, depending on their required application (see illustration).

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.


Installation 33.1 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 supplied.

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 20)). 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 31)).

5. Closing the junctions: Place the covers on the mechanical junctions (see Connecting units (Page 20)).

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. 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.

Installation 3.4 Attaching fixing material


3.4 Attaching fixing material

3.4.1 Typical procedure The BD2 busbar trunking system is generally attached to the structure of the building using externally provided supporting structures (e.g. threaded rods, C-profiles, joists or stands for intermediate levels) and the system-specific fixing bracket.

3.4.2 Overview

Types of fixing material ● Fixing material not available in the catalogue (plugs, beams, suspension struts, spigots,

etc.) must be provided by installation experts. ● Bracket for horizontal installations (ceiling/wall/floor brackets) ● Bracket for vertical installations (wall and floor brackets)

Attaching fixing material In all cases, proceed as follows: 1. Attach the fixing brackets to the building via the supporting structure. 2. Raise the BD2 element and suspend it on the brackets without securing it. 3. Move the element until it is inserted in the adjoining joint block and place it in its final

position. 4. Secure the element.

Note Consulting installation experts These instructions only refer to accessories manufactured by SIEMENS. For further information, please refer to the catalogue. It is beyond the scope of this manual to document the vast number of different on-site conditions that may arise. Therefore, we recommend that installation experts evaluate on-site conditions.

WARNING

Always follow the instructions provided in the manual and the AWAs.



3.4.3 Bracket for horizontal installations

Ceiling bracket ● Attach the suspension bracket to the ceiling or another suitable structural support. ● Ensure that the ceiling or structural support is strong enough to hold the weight of the

system. ● Place the element to be suspended in its intended final position on the brackets, leaving

the element in a horizontal position. ● Join the adjacent elements. ● The surface finishes of the fixing strut and the screws must be adapted to on-site ambient

conditions.

Figure 3-1 Ceiling bracket

Note When selecting plugs to use, take the ceiling material and quality as well as the weight to be supported into account.

Never knock or hit the joint block when inserting it between the two elements. Instead, insert it carefully, otherwise the elements may get damaged.

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.

Installation 3.7 Flanged end


3.7 Flanged end

3.7.1 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 3-9 Flanged end

3.7.2 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.

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.

Installation 3.8 Cable feeder units


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.

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 busbar package. Please refer to the description in Connecting units (Page 20) for details on how to perform the mechanical and electrical connection; the electrical connection is performed as described in Installation (Page 25) .

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 with one supply cable. In this case, you must ensure that the loads are protected against short circuits and overload, either via an upstream protective device or by additional protective measures.

Installation 3.9 Fire barrier


3.9 Fire barrier

3.9.1 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.

3.9.2 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 3-10 Internal fire barrier (left), internal and external fire barrier (right)

Installation 3.10 Tap-off unit


3.10 Tap-off unit

3.10.1 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 on-site regulations.

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.

Figure 3-11 Tap-off units up to 530 A and ancillary equipment units for additional installed devices

with tap-off units up to 125 A



3.10.2 Lateral mounting of tap-off units BD2-AK04 (05, 06) in runs for horizontal installation

If the tap-off units are mounted laterally, the mechanical load caused by the weight of the units and the cables to be connected mean that we strongly recommend you use additional supports (beams or brackets).

Figure 3-12 Laterally mounted tap-off units should have additional mechanical support

A Additional beam for tap-off unit B Tap-off unit C Busbar run D Beam for busbar run

Additional beams in line with A and D are not available as BD2 attachment accessories and must be procured externally.

Note It is beyond the scope of this manual to document the huge number of different on-site conditions that may arise. Therefore, we recommend that installation experts evaluate on-site conditions.




Commissioning 44.1 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. Check that all connections are fully tightened. Follow the instructions relating to tightening

torques (visual inspection with record of results). 2. Check all suspension and fixing elements. All the fixing studs and screws of the fixing

brackets must be tightened. 3. Make sure that all tap-off units and tapping equipment is disconnected (OFF). 4. Insulate the busbar trunking system from the connections to transformers, switches,

meters, etc. 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 country-specific 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.

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 connecting the line.

4. Once the line has been connected, consumers such as lights, contactors, heaters and motors can be switched on.

5. In normal operation the busbar trunking system will produce a slight buzzing sound. Excessive noise may indicate that components have not been properly secured or metal parts have been incorrectly assembled.

6. 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 de-energised 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.


Service and maintenance 55.1 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. This involves removing the busbar trunking system element from the BD2 run.

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. ● There are no extreme stresses/loads due to aggressive media. ● There are no other malfunction-based loads/stresses due to short circuits, fire or gas. This maintenance-free claim does not include devices fitted in tap-off units, feeder units or coupling units. The instructions on their maintenance should be taken from the respective manuals/documentation supplied with the devices. If any of the conditions listed above cannot be guaranteed, you should consult your SIEMENS contact directly. Please also get in touch with your SIEMENS contact for any additional inspections that have to be performed regularly for the erector and operator due to country-specific standards, regulations on accident prevention and safety, as well as for special work areas.

Service and maintenance 5.3 Dismantling busbar trunking system elements


5.3 Dismantling busbar trunking system elements

Dismantling busbar trunking system elements It may sometimes be necessary to dismantle a length of the busbar trunking system for the purposes of expansion or replacement. These instructions indicate the correct procedure to follow in such a case.

WARNING Before disconnecting, take the switching capacity of the busbar trunking system protector element into consideration. • All power must be disconnected before you disconnect the busbar trunking system. • The header protection systems must be disconnected in order to insulate the busbar

trunking system.

WARNING Remember to completely disconnect the line before handling. 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

NOTICE Only qualified personnel with electrotechnical knowledge may perform the operations indicated in this section.

1. Disconnect all power to the busbar trunking system. 2. Disconnect the busbar trunking system from the supply. 3. Fully insulate the busbar trunking system and safeguard it against restart. 4. Remove the flange cover of the relevant elements. The first element must be removed in a transversal direction. All other elements can be removed in a longitudinal or transversal direction. The busbar trunking system must be handled in accordance with the AWA (see installation instructions).
