6.3 Shield connection
Make sure you observe the correct design of the shield support for the shielded cables. It is
the only way to ensure immunity of the system.
A cable is shielded to attenuate the effects of magnetic, electrical and electromagnetic
interference on the cable. Interference currents on cable shielding are diverted to ground by
conductive isolation rails. To avoid interference as a result of these currents, it is imperative
to provide a low-impedance connection to the ground.
Only use cables equipped with a shielding braid. Shielding density must be at least 80%.
