Note
With a hanging chain arrangement:
The cables will become longer in operation.
• Ensure that there is more play "X" than that specified in assembly
step 3.
• Check the length of the cables after a short operating period and adjust,
if necessary.
6. Fitting the cables in energy chains
1. Lay the chain out in length.
2. Lay the cables without twisting in the chain. Lay or hang out the cables
first, if necessary.
3. Lay the cables loose next to each other in the chain, if possible separated
from each other by separator links or holes. Observe the play "X" of
cables of 10% of the cable diameter "D". Avoid arrangements with cables
on top of each other if separator links are not used ! Fig. 1.

4. After laying the cables, arrange the chain in the work position.
5. Make sure that the cables are not bent to a radius less than the permitted
bending radius "R".
6. Make sure that the cables can move freely in the bending radius "KR",
the cables must not be forced through the chain ! Fig. 2.

7. Leave the cables unfastened in the chain, do not tie the cables together.
8. Fasten the cables on both ends of the chain ! Fig. 3.
With long energy chains in which the upper drum lies on the lower drum,
fasten the cables only at the driver end ! Fig. 4.
9. Make sure that the cables cannot be moved up onto fastening point.
Make sure that the distance from the end point of the bending movement
on the fastening is as large as possible, at least fastening distance "A"
! Fig. 3 + 4.
