General safety Information kg r If cable support systems are touched with bare hands, then cutting could result on account of the sharp edges. Always wear suitable protective gloves when handling system parts. When working with the cable support system, in particular during shortening, e.g. with an angle grinder, splinters and chips may result, which can cause injury. For this reason, wear personal protective equipment (PPE) during mounting. If the maximum load capacity is exceeded, the cable support system may collapse. Comply with the load limits! Cables can be damaged on bending. When inserting the cables, ensure that the minimum bending radius, prescribed by the cable manufacturer, is observed. . . .

DE | 3 2. Straight connection of mesh cable trays The GR-Magic® mesh cable tray system with shaped connector for screwless quick mounting guarantees the shortest possible installation times, even for complex mounting operations.. 1 1 Connection of lengths stock lengths Fig. 2.1.1 Connect the mesh cable trays, as shown. Fig. 2.1.2 The three transverse wires run in parallel when mounted.

1.2 Connection of cut mesh cable trays Fig. 2.2.2 Positioning and quantity of mesh cable tray connectors. Width 50‒150 mm = 2 Width 200‒300 mm = 3 Width 400 mm = 4 Width 450‒600 mm = 5 Fig. 2.2.3 Use of the quick connector type GRS 3.9 or GRS 4.8 ana- logue to the mesh cable tray wire thickness. For use with mesh cable trays up to a width of 150 mm. Fig. 2.2.1 Use of the joint connector type GSV 34.
