● Avoid placing the motor cables in long parallel lines with other cables.
● If the motor cables run in parallel with other cables note the minimum distances
between the motor cables and other cables given in the following table.
Distance Between Shielded Cable, m
Cables, m (ft) (ft)
1.0 (0.3)
3.2 (1.0) ≥ 656 (200)
● The given distances also apply between the motor cables and signal cables of
other systems.
● The maximum lengths of motor cables (shielded) are:
– 328 ft (100 m) (FS4)
– 493 ft (150 m) (FS5 and FS6)
– 656 ft (200 m) (FS7 to FS9).
● The motor cables should cross other cables at an angle of 90 degrees.
● If cable insulation checks are needed, see the
section [➙ 66].
Start the cable installation according to the instructions in the following section.
