4.6.2 - Shield connection
A shield has no effect if it is not connected:
- to a reference potential,
- via a 360° shield connection at both ends. This means that the whole shield sleeve circumference must be
directly in contact with the reference signal without any conductor insertion.
Cables with low potential should never run in the proximity of high power lines.
The connectors used for the compliance with the EN61000.4 standard must be made of metal or metalized and
must allow the 360° shield connections.
The shield of the motor and brake cable must be connected over 360°.
The 360° shield connection must be ensured by metallic collars and connected to the ground reference potential.
The shield should never be interrupted or corrupted over the whole cable length.
