5. Instructions for cables in energy chains
Note
If there is a chain breakage:
The cables can be damaged due to overstretching.
 Replace all the cables after a chain breakage.
With a vertical energy chain:
The cables will stretch during operation.
 Ensure that there is more clearance "X" than 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 lengthwise.
2. Place the cables in the energy chain, making sure they are not twisted.
Lay out or hang the cables first, if necessary.
3. Lay the cables loose next to each other in the energy chain, if possible
separated from each other by separators or holes. Ensure the clearance
"X" of the cables is 10% of the cable diameter "D". Avoid placing cables
on top of each other if separators are not used.

4. After laying the cables, place the chain in the working position.
5. Make sure that the bending radius of the cables does not fall below the
permissible 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.

7. Leave the cables loose in the chain, do not tie them together.
8. Fasten the cables to both ends of the chain ( Fig. 1).
9. With long energy chains in which the upper run lies on the lower run, fas-
ten the cables only at the driver end ( Fig. 2).
10. Make sure that the cables are on no account moved all the way to the
fastening point. Make sure the spacing between the end point of the
bending movement and the attachment is as large as possible, but at
least as large as mounting space "A".
