24 V overvoltage protection signal cable protective conductor
1)
The metal enclosure of the component and the protective conductor connection of the overvoltage protection ele‐
ment must be connected with one another in a way that ensures good conductivity (equipotential bonding). You can
achieve this, for example, by mounting the component on a metal mounting plate in a way that ensures good
conductivity and connecting the protective conductor connections of the overvoltage protection elements to the
mounting plate through the shortest distance.
2)
By snapping the overvoltage protection element for the signal cables onto a metal DIN rail, the protective conductor
connection is connected to the rail. In this case, it is sufficient to establish a good conductive connection between the
DIN rail and the metallic enclosure of the component (equipotential bonding). To establish this connection, you must
mount the DIN rail and the component on a common metal mounting plate.
