4 Description Features End flanges Type-tested low-voltage switchgear and controlgear assembly (TTA) to IEC/E and -2 Reduced planning costs through simplified engineering Quick-release plug-in connection for fast assembly Tap-off points on both sides for optimized utilization of the busbar Even electrical loading of the CD system conductors by connecting an equal number of tap-off plugs to each individual phase Versatility through high degree of protection to IP54 of the standard version Tap-off plugs allow fast, flexible load relocation. These flanges provide protection against direct contact at the ends of the busbar run. They are suitable for use with all CD systems. Feeder units Trunking units a Locating section b Connection terminal c Tap-off point The trunking units are available in lengths of 2 m and m. They consist of a rectangular, galvanized metal housing with a white-grey paint finish. Two variants are available: Entry feeder unit for 2 25 A, 0 A and 40 A End feeder unit for 2 25 A, 0 A and 40 A. One end flange is included as standard with each unit. Cable entry from three sides. Use metric M25 or M2 plastic cable glands with strain relief (not included as standard). They are fitted with the following conductor runs on one or both sides: 2 for + (PE = housing) for + + (PE = housing) 4 for + + L + (PE = housing) Single conductor run: tap-off points at intervals of 0.5 m or 1 m Two conductor runs: tap-off points at intervals of 0.5 m or 1 m Tap-off plugs The tap-off points on the trunking units accept insulated enclosed tap-off plugs. The following versions are available: -pole and 5-pole versions without fuse base with halogen-free, flame-retardant cable. -pole and 5-pole version without fuse base with terminal and plastic M20 cable grommet. -pole version with fuse base for 8.5 mm 1.5 mm type gg (IEC) and type gl (VDE) fast cylinder fuses, with halogen-free, flame-retardant cable. -pole and 5-pole versions with fuse bases for one or three 8.5 mm 1.5 mm type gg (IEC) and type gl (VDE) fast cylinder fuses; with terminal and plastic M20 cable grommet. The tap-off points are spaced at regular intervals of 0.5 or 1 m on the trunking unit. The trunking unit housing acts as the PE conductor. Three current ratings are available: 2 25 A, 0 A, 40 A. All trunking units have touch-proof tap-off points, that can be coded by the user. Connection method The trunking units, including those with feeder units and flanges, are assembled without tools by straightforward plug-in connection. The PE path is established automatically when the housings are connected. An interlock mechanism with two fixings prevents a loosening of the connections between the trunking units, feeder units and flanges. o expansion compensation is required. The -pole tap-off plugs have a variable phase tap-off, i.e. they can be connected to, or L. /4

5 Description The phase tap-off can therefore be changed by simply changing the contacts to another terminal. L PE Coding Coding can be used for various frequencies and voltages. It can be retrofitted to the CD-K-... trunking units and the CD-K-A... tap-off plugs. Three code settings are possible: CD-K1 (K2, K). + + PE + + PE L + + PE On the 5-pole tap-off plugs, the phase tap-off can not be changed. The phase assignment of the tap-off plugs is visible from the outside. L L Suspension The trunking unit profile allows attachment of the suspension and fixing brackets at any point of the trunking unit. Tap-off plugs with terminals accept cables up to 2.5 mm 2. L L Fixing bracket for trunking units and suspension bracket for luminaires up to max. 20 kg (5-fold safety to DI ). For more accurate centring, the CD-GP threaded plate can be used. Fixing bracket for suspending trunking units and for increased mechanical rigidity at the trunking unit connection points. L Supplementary components Underfloor mounting Fixing bracket for underfloor mounting Clip-type fixing bracket for suspension from the trunking unit and for mounting luminaires (for luminaires up to max. 20 kg at 5-fold safety to DI ). Also allows cables to be routed alongside the system at a later stage.ab Clip-type fixing brackets must be used only for balanced loads, not for concentrated loads. Cables routed with the trunking unit can be secured using the cable clip. /5

11 Engineering Short-circuit protection The lengths of the CD busbar runs given in the guide value tables on Page /9 and Page /10 take into account only the rated current of the connectable luminaires. To determine the precise length of the busbar run, voltage drops and short-circuit protection must be taken into account. l inc. z inc. l CD z CD Protective device Incoming cable CD-System Luminaire x Tap-off with cable mm or 1,5 mm 1.

For example: Z Inc = Ω/m at 2.5 mm 2 Z CD = Ω/m for 0 A CD system Ω/m for 40 A CD system Ω/m for 2 25 A CD system Z Out = Ω/m at 1 mm Ω/m at 1.5 mm 2 Provided that the protective element is positioned immediately upstream of the CD system feeder unit, Z Inc can be ignored. /11

12 Engineering Short-circuit protection Overcurrent protective devices for overload and short-circuit protection A system can be protected against start circuit alone, by fitting low-voltage h.b.c. fuses (gl) into the incoming supply; the fuse size to be appropriate for the prospective short-circuit current at the point of installation. Due to their high response threshold ( times rated current) and their long rupturing times at small overcurrents, fuses are not suitable for overload protection. For protecting the CD busbar trunking system and its outgoing circuits, we recommend miniature circuit-breakers and motor-protective circuit-breakers. System CD-10. CD-140.
