<p>The support frame, for electrical equipment and wiring, has two vertical members joined by horizontal members. Mounting rails or panels are used for fixing the equipment and U-shaped ducts are used to hold the wiring. The wiring ducts (8) are constructed as supports for the mounting rails (6) or panels (7). They have flanges (9) to hold the rails or panels and flanges for fixing to the vertical members (2). The duct/vertical-member connection is achieved by a plug-in arrangement whose direction of engagement is parallel to the vertical members. The ducts have internal insulation.</p> |
