Wiring Precautions on Movable Section
When wiring cable bear, take the following precautions:
• Cable bear wiring
The bend radius of the cable must be 10 times or more its finish outside diameter.
The minimum radius: R > =20 mm.
For finish outside diameter, refer to P.1-18 How to Install, "Relationship between Wire
Diameter and Permissible Current" and associated tables.
Do not fix or bundle wires in the cable bear.
When securing the cable, fix it only at non-movable ends of the cable bear where the
cable is free from any stress (e.g. tension). (Avoid tight lock.)
[Recommended cable bear wiring]
Caution
Do not keep the cable loosened (too long) or under tension (too short).
Otherwise, the sheath will be cracked by internal wall of the cable bear, tangled by other
cable, etc., causing unpredictable troubles.
• Cable distortion
Keep the cable free from twists or kinks.
Distorted cable will cause loose connection, lowering performance and reliability.
• Lamination factor of cable in cable bear
Place cables on a flat surface in parallel without bringing them into contact with each
other and measure the dimension necessary to cover these cables. Then select a ca-
ble bear which is wider than the measured dimension.
The lamination factor of cables should be lower than 60% (recommended factor is 0%
or below).
Do not run smaller and larger size cables in the same cable bear. Thin cables may
break under the pressure of thick cables. If it is necessary to mix cables of different
size, isolate them by using suitable separating material such as partition.
