Do never pull on thecable, when loosening the connectors.Cables in Drag chains●●●●●Do not lay the cables over sharp edges.Always observe the minimum bending radius! The same applies for storageon drums or in rings.Avoid high temperature fluctuations during storage. For storage outside,use covers.Cables have always to be unrolled. Do never unroll "over head".Do never use damaged cables.To mount the cables in drag chains in the right way, some basic rules have tobe taken into account. Inserting the cables into the drag chains is to be donewith utmost care.●●●●●●●Do only use cables, which are suited for the use in drag chains.The minimum bending radius of the drag chain is determined through thecable with the biggest outer diameter.Lay out or hang out the cables before mounting so that the twisting disappears.An axial twisting of the cables must be avoided in any case.Lay the cables into the drag chains tension-free and twisting-free.Lay only laid out or hanged out cables into the drag chains and then mountthe chain into the machine.Ensure that the cables do not intersect or overlap each other in the chain.The cables have to be freely movable in the area of the bending radius aswell as in the width and height. The overall diameter of the drag chain orrack / hole segment must only be filled with 85-90 %.Fig.8-9:●●Filling degree of drag chainsIt is not allowed to fasten or to bind the cables together within the chain.When equipping the drag chain, it must be taken into account that theweight must be distributed as symmetrically as possible. In other words,install heavy cables in the outer and lightweight cables in the inner section.Fig.8-10:Symmetrical distribution within drag chains
