4.2 Earthing and equipotential bonding
If the device is not sufficiently electrostatically grounded via the process cables, an additional
earth connection must be established using the earth screw 1. The position of the ground
terminal is illustrated below. The connection guarantees only an electrostatic connection of the
device and does not comply with the requirements of an equipotential bonding connection.
