For securing trunking units to the illustrated supporting structures.

To simplify engineering of BD2 systems, engineering symbols have been introduced. On the engineering drawings, these symbols clearly indicate the component moun-ting position, the phase sequence, the open busbar end, the end with the terminal, the position of the flange cover and the side from which the terminal can be acces-sed.The following conventions apply to all components of the busbar run (feeder units, straight trunking units, branch units and junction units):

Open busbar end

Phase sequence, PE on the right

The PE side is marked with a bold black line.

Terminal end of the trunking unit

Terminal access side Top flange cover

Example: Straight trunking unit with tap-off points on both sides,Type: BD2.-...-SB-.

The engineering symbols are used on the selection data pages.

Determining the orientation of L units

= L = Left = V= Front = R= Right = H= Back

Example: Elbow, right, Type: BD2.-...-LR

= R = Right

Determining the orientation of feeder unitsOn feeder units, the position of the cabling box relative to the trunking box is not critical for type selection, since the busbar connection flange can be turned on site to provide the required phase sequence.

Horizontal installationWith the BD2 system, the mounting position can be chosen as required, allowing a horizontal busbar run to be laid out in two ways:

Horizontal, edgewise

Horizontal, flat

As can be seen from the illustration, any phase sequence is possible. A reduction factor in horizontal edgewise mounting position (x 0.9) is necessary with power transmission.This applies for straight trunking units and branch/junction units. The engineering symbol identifying the type shown on the selection page only needs to be turned to the desired mounting position in the engineering drawing.

Example: Elbow, right, Type: BD2.-...-LR

Horizontal edgewise mounting has the advantage of a larger suspension span and the need for fewer accessories (flanges) to achieve IP54 degree of protection (a page 5/10).

Vertical installationWhen engineering vertical busbar runs (a page 5/22) the height of the storey measured from the centre of one ceiling to the centre of the next determines the choice of busbar trunking lengths. If no fire barriers are required, standard lengths with protective sleeves can be used. In this case a distance of at least 0.185 m must be maintained between the end of the trunking unit and the upper edge of the pro-tective sleeve.For vertically mounted systems, only one mounting position is possible.The PE bar must always be on the right-hand side, and the trunking unit end with the clamp terminal must point towards the top. This ensures that• the flange cover can be push-fitted to the terminal from the front and the screws

can be tightened,• the tap-off units are not mounted upside-down, i.e. they can only be fitted in the

Dimension

Straight trunking unit, optional lengths BD2.-2, BD2.-3 tap-off point clearance = 0.5 m, (BD2.-1 tap-off point clearance = 1 m)The open busbar end is used as the reference edge. The grid spacing between the tap-off points is shown in the diagram.

Distance x is the distance between the centre of the terminal at the open end and the next tap-off point on the trunking unit. For the standard length x = 250 mm. For optional length, 260 mmFxF 490 mm (depending on the optional length w).

Measuring and determining the optional lengths on site

On site, the dimension a between the housing edges of the two trunking units to be connected is measured. The optional length is then determined as follows:

Branch junction unitsX dimension (side with open busbar end): from centre of terminal to outside edge of housingY dimension (side with clamp terminal): from centre of terminal to outside edge of housingZ dimension: from one outside edge of the housing to the next Dimensioning data a page 5/84.

Overload and short-circuit protection

Busbar trunking systems must be protected against overload and short-circuits. Fu-ses and circuit-breakers are used for this purpose. The highest prospective short-cir-cuit currents, selectivity requirements or operator control and signalling functions may be deciding factors in selecting protective devices.Due to their high response threshold (1.3 to 1.6 times rated current) and their long rupturing times at small overcurrents, fuses are generally less suitable for overload protection.To ensure that fuses provide sufficient protection against busbar trunking system overload, the rated current of the fuse must be one level lower than the rated cur-rent of the busbar trunking system to be protected. This prevents optimum utiliza-tion of the busbar trunking system.

If circuit-breakers are used, the thermally delayed overload release is set to the ra-ted current value for the busbar trunking system. This allows 100 % utilization of the system. Where fuses and circuit-breakers are used for short-circuit protection, the specified short-circuit rating of the busbar trunking system must not be exceeded.The need for a current limiting protective device and the required short-circuit bre-aking capacity of the protective device depend on the magnitude of the prospective short-circuit current.The table below provides an overview of the circuit-breakers suitable for short-cir-cuit and overload protection (400 V and 50 Hz) of the respective busbar trunking sy-stem.

The following applies:

I ″k = prospective short-circuit current at the installation locationIcc = rated conditional short-circuit current of the busbar trunking systemIcu = rated short-circuit breaking capacity of the circuit-breaker

The conditional rated fused short-circuit current Icc values below apply to the busbar trunking systems without consideration of any tap-off units.

Installation planIt contains: the position of the busbar trunking system in the building, the position of the PE and the tap-off openings and consequently the installation direction of the tap-off units,the number of components with item numbers and the method and height of sus-pension. The information assists the installer later. If the system is correctly assembled, the entire system will have the same sense of rotation as the three phase motors throughout the entire system. As a result, it will not be necessary to check the direction of rotation of the motors when relocating a machine.

Fire barriers

To ensure fire protection to S90 or S120, the following points must be observed when engineering and installing trunking and junction units with fire barriers:• The centre of the fire barrier in the trunking unit must be positioned in the centre

of the fire wall or ceiling.Exception: With branch/junction units, this may not be possible due to insuf-ficient clearance from the wall or ceiling, i.e. the centre of the fire barrier may not coincide with the centre of the fire wall or ceiling. In such cases, PROMA-TECT-H(L) panels are added to achieve the actually required wall or ceiling thick-ness.

• The following information must be provided: For BX*, BY* and BZ* trunking units, position of the centre of the fire barrier in the trunking unit (or the centre of the fire wall or ceiling for branch/junction units with insufficient clearance from the wall or ceiling); the desired fire resistance rating S90 or S120; and the thickness M* of the wall or ceiling.

• There are no tap-off points in the area covered by the fire barrier.• The trunking units must be installed by an approved fire protection installation

specialist.

NotesFor BX* and BY*, replace the asterisk in the type reference by the required dimen-sion in metres from the centre of the clamp terminal (end without clamp terminal) to the centre of the fire wall or ceiling; for -M* specify the wall or ceiling thickness.For BZ*, replace the asterisk in the type reference by the required dimension in metres from the outside edge of limb X to the centre of the fire wall or ceiling; for -M* specify the wall or ceiling thickness.

2) For Z units depending on the lengths X*, Y*.

For installing trunking units with fire barriers, the following points must be observed in addition to correct positioning:• Horizontally mounted busbar runs must be supported by a fixing bracket fitted ap-

prox. 500 mm before and after the structural element they pass through.• The space surrounding the busbar trunking unit within the structural element it

passes through must be packed with mineral-based mortar or ZZ fire barrier sealant TS90.

• The gaps between PROMATECT-H(L) panels, the busbar trunking unit and the structural element must be sealed with ZZ fire barrier sealant TS90 (included as standard if panels are specified).

• The installation must be carried out to pertinent building regulations.• ZZ fire barrier sealant TS90 is available from:

Diederich Industrievertretung (Brandschutztechnik), Cologne(Tel.: +49 221 966520; Fax: +49 221 966522).

Notes The mortar or ZZ fire barrier sealant TS90 must conform to the applicable regulations for establishing fire resistance rating or the construction of the wallor ceiling (e.g. DIN 1045 and DIN 1053 Part 1)
