ƒ The motor cable is optimally installed if
– it is separated from mains cables and control cables,
– it only crosses mains cables and control cables at right angles,
– it is not interrupted.
ƒ If the motor cable must be opened all the same (e.g. due to chokes,
contactors, or terminals):
– The unshielded cable ends may not be longer than 100 mm
(depending on the cable cross−section).
– Install chokes, contactors, terminals etc. spatially separated from
other components (with a min. distance of 100 mm).
– Install the shield of the motor cable directly before and behind the
point of separation to the mounting plate with a large surface.
ƒ Connect the shield with a large surface to PE in the terminal box of the
motor at the motor housing.
– Metal EMC cable glands at the motor terminal box ensure a large
surface connection of the shield with the motor housing.
