In systems in which no equipotential bonding is possible, the current flow via the shield
needs to be prevented. Despite this, to be able to use the shield properties of the cable note
the following:
● Contact the shield at one end with low resistance.
● Connect the other end of the shield to the grounding system using capacitive coupling.
