ELECTROMAGNETIC COMPATlBlLlTY PRECAUTIONS ( W 3 )
At not time should the screening cable replace the yellow-green earthing cable.
ADVICE : In order to ensure the electromagnetic compatibility, it may be necessary to use to connect to the
rnotor, a rnetal stuffing box with a screening contact allowing an efficient electrical link between
the flat screening cable and the metal housing (see figure below).
If the motor terminal box is isolated, then a metal stuff box is of course useless. The screening
cable should be linked in the shortest way to the rnotor earth terminal block.
