• 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.

≥ 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 Cable and motor insulation
checks section [➙ 67].
Start the cable installation according to the instructions in the following section.
