3. General assembly instructions
 Observe the permissible tightening torques M
4. Instructions for cables in energy chains
Note
If there is a chain break:
The cables can be damaged due to overstretching.
 Replace all the cables after a chain break.
With a vertically hanging chain array:
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.
5. Mounting 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 without use of separators.

4. After laying the cables, adjust the chain in the operation position.
5. Make sure that the bending radius of the cables is not smaller 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.

7. Leave the cables loose in the chain; do not tie them together.
8. Fasten the cables at 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 distance between the end point of the
bending movement and the attachment is as large as possible
but at least equal to mounting space "A".
