Connection of shielding at one end only of the cables linking the controller and Panel PC:

Controller

Connection of the shielding at one end only is recommended when there is inadequate equipotential bonding, or none at all.

In such cases an electrically isolated power supply unit must be used.

If the shielding were connected at both ends, the equipotential bonding current would flow to point A and this must be

avoided at all costs, as the resultant interference pulses could be passed on to the devices via the data cable. When

shielding is connected at one end only it must be on the side that has the lowest resistance earth connection.

Before the equipment goes into service the directions from the controller manufacturer regarding proper assembly and

operation must be read carefully. They should then be applied taking full account of the recommendations we make here.
