2 Products
2.1 Basic description busbar trunking syst. 1100A to 5000A (AC), 1900A to
6920A (DC)
The busbar trunking systems shall be delivered and installed as design
verified low-voltage switchgear and control gear assemblies according to
IEC/EN 61439-1 and -6, ready for connection.
The following descriptions are integral parts of the calculation and the
contract. They must be considered in the descriptions of the individual
systems and operational equipment, even if they are not mentioned in detail
anymore.
The busbar trunking system must be suitable for power transmission, for
example, between transformer and low-voltage main distribution, and for
power distribution as an overall power supply both for horizontal and
vertical installation.
The busbar trunking system must consist of standardized system components
such as:
· Straight trunking units with and without tap-off points
· Feeder units for transformer, distribution board and cable infeeds
· Junction units with elbow, offset elbow, knee, offset knee, Z-units and
T-units
· Tap-off units
· Accessories

· All straight trunking units must be available ex works in lengths up to

max. 3.2m. Flexible junction units, and junction units as cable
connections are not allowed.
· Expansion compensation units and fixed points shall be configured as
required.
· The trunking units are protected against incorrect mounting (anti-
rotation feature for correct phase sequence).
· The busbar trunking systems with tap-off openings must be equipped with
tap-off units as required. The position and number of tap-off points
must be selectable.
· If necessary, it must be possible to provide the busbar trunking system
with an asbestos-free fire barrier towards the wall or ceiling opening,
certified according to EN 1366-3 and optionally conforming to the fire
resistance classes EI90 or EI120 according to EN 13501 (formerly S90 and
S120).
· If necessary, it must be possible to offer the busbar trunking system
with the functional endurance classes E60 or E90 according to DIN 4102-
12.
· The fire barrier for functional endurance must be mounted by the
installer on site. The functional endurance certificate must be enclosed
with the offer.
· The housing consists of zinc coated sheet steel.
· The individual system components must be connected by fitting a hook
into a bolt, and tightening a state-of-the-art bolt-type terminal. The
required torque for the clamping connection is 80 Nm.
· The busbars must be made of aluminum or copper, and be insulated along
their entire length.
· The aluminum busbars are nickel- or tin-plated, the copper busbars are
tin-plated. The insulation is made of highly heat-resistant insulation
coating
· The conductor cross-sections must not be below the values given in the
technical data.
· For operation with DC voltage, the product must be appropriately
qualified and clearly marked from the outside.

2.2 Conformity and test evidences

The manufacturer of the busbar trunking system has to run and furnish
evidence of a certified quality management system according to EN/ISO 9001.
Certificates or declarations of conformity must confirm the following
qualifications for the entire system:

to ISO14040
Reliable proof of special, additional features (such as sprinkler test) of
system components must be available.
The manufacturer must guarantee that functional disturbances due to the
formation of whiskers are excluded by suitable measures such as air
clearances, insulation or nickel barrier layer.

2.51 G3-PLC power line modem for data transmission via the busbar

G3-PLC power line modem for data transmission via the busbar

Brief summary:
The G3-PLC power line modem is used for data exchange between
communication-capable low-voltage switchgear and control gear across all 3
phases of the low-voltage busbar system. It uses the Access Power line
Communication standard (Access PLC) for data transmission. In this case,
one G3-PLC modem ("client" operating mode) is installed in the power line-
capable busbar tap-off unit and another in the power distribution system
("PAN coordinator" operating mode). The devices are connected via RJ45
(Ethernet) or RJ12 (serial).
An external supply voltage is not required. The connection is parameterized
via the integrated web server of the modem.
Functions:
· "PAN coordinator" operating mode: Demodulation of the modulated power
line information and conversion to Modbus TCP or serial information
· "Client" operating mode: Modulation of the information connected to the
RJ45 (Modbus TCP) or RJ12 (serial) interface onto the power line
· Automatic configuration, no local configuration required
· Pushbutton: Reset / factory settings
· LEDs: Status display, PLC connected / data transmission, fault
indication
· Frequency range: 150 to 500 kHz
· Automatic setup of PLC network
· Dynamic routing mechanism supports mesh networking and automatic
adaptation of connection to select the optimal transmission path.
· Automatic Repeat Request (ARQ) improves error detection and reliability
of data
Technical specifications:
· Standards: G3-PLC specification (ITU-T G.9903)
· Mounting: DIN rail
· Protocols: IPv6, IPv4, IEEE 802.3
· Baud rates (gross): 240 kbps (max D8PSK)
· Modulation: Robo, DBPSK, DQPSK, D8PSK (OFDM)

2.52 Repeater box, LD system

If the required transmission distance
· between 2 tap-off units with power line
Or
· between a tap-off unit with power line and the receiver module in the
switchboard
Is longer than the distance that can be bridged as a maximum with power
line communication, it will be necessary to install a repeater box with
integrated repeater (G3-PLC modem) each at a suitable point, in order to
ensure secure communication of the power line signals between the tap-off
units as well as between the tap-off-units and the switchboard.
The repeater boxes to be used can be mounted at the corresponding point of
the busbar like tap-off units.
The distance that can be bridged as a maximum with power line communication
depends on the power quality (e.g. harmonic content) and the topology of
the busbar trunking system (number of feeders), and can be between 200 and
1000 m.
The number and position of the repeater boxes required in the busbar run
must be determined based on the specific conditions of the project to be
implemented.

2.53 Basic description of energy units

The energy points for DC systems must be equipped with coding angles to
prevent defective installation. De-energized condition during installation
of a energy unit must be ensured by positively defined operations or by
instructions to be observed.
The current tapping of the energy unit must be equipped with a leading PE
connection contact.
The energy units are protected against incorrect mounting (anti-rotation
feature for correct phase sequence) and the degree of protection IP2X must
be ensured by a facility throughout the complete plugging process.
Energy units shall be available with
· Molded case circuit-breakers
· fuse switch-disconnectors

Revit), .IFC (Industry Foundation Classes)) in order to be integrated in
the BIM (Building Information Modelling) of the building project.
Using the 3D data in the BIM process contributes to efficient and thus
sustainable planning thanks to the following factors:
 More efficient planning resulting from the same level of information for
all persons involved with respect to the information that is relevant
for them
 Possibility of early, efficient and precise error and weak point
analyses in the planning process
 Consideration of aspects concerning the optimization of operation and
maintenance already in the planning phase
