-E- Suitable for energy chains In energy chain or flexible
Tab. 2 Wiring
4.3 Mounting in energy chain
1. Lay the chain out lengthwise.
2. Place the cables on the chain, making sure they are not twisted.
3. Separate cables from each other using separators/drilled holes.
4. Do not connect cables together.
Fig. 3
5. Maintain spaceX. X>10%of the cable diameterD.
If the chain is suspended vertically: increase spaceX.
Fig. 4
6. Align chain in the operating position:
– Make sure that the radius is greater than the bending radiusR of the
cables.
– Cables can move freely in the bending radius KR of the energy chain.
ÄCables are not forced through the chain.
7. Mount the energy chain ècorresponding instructions.
8. Fasten cables:
–with short energy chains (length <1m) at both ends of the chain
–with long sliding energy chains (length >1m) only at the driver end
Fig. 5
9. Do not move cables all the way to the fastening point.
ÄMounting spaceA between the fastening point and bending movement is
maintained.
NOTICE!
Damage to cables if the chain breaks.
• Replace cables after a chain break.
NOTICE!
Malfunction and material damage due to vertically suspended cables.
The cables stretch.
• Regularly check the length of the cables.
• Readjust the cables if required.
