ELECTROMAGNETIC COMPATIBILITY PRECAUTIONS (2/4)
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
motor, a metal 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 motor earth terminal block.
3. The other links between the MB32 Vector drive and the motor, i.e. .the brake (+BR and
-BR), the motor thermistor (0V, STH) can run together but kept at least 10 cm from the
power cables.

Note: Keep the motor cable as far apart from the power cable

once inside the terminal box.
