1)
The metallic enclosure of the component and the protective conductor connection of the overvoltage protection
element must be connected with one another, ensuring good conductivity (equipotential bonding). You can achieve
this, for example, by mounting the component on a metallic mounting plate, ensuring good conductivity and con‐
necting 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 metallic mounting plate.
