MODULAR LIGHTING SYSTEMS 27 The channel section with supporting flange is ceiling-bearing . The channel section is suspended directly from the structural (load-bearing) ceiling by steel cords and performs a load-bearing function for the ceiling modules which are laid onto the flanges. After adjust-ment, the through-wiring is fitted, and the power supply (if applica-ble, also a building management system) is connected.The channel sections are cut to the desired length on site. Theappropriate number of standard lengths (1,600 mm) is calculatedaccording to site requirements. Finally, they are blanked off by a 3-part blank section which is cut to length on site. In some cases ashorter 800 mm section is required instead of a single 1,600 mmstandard section (see page 16). The connectors for the channelsections are included in the scope of supply with the sections and do not have to be ordered separately. The same applies to the end plates. They need only be ordered as an extra set if no blank sec-tions are used.
