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:

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.

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.

3.7.2
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.
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.

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.

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.

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.

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).

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.

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.

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
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.
