Create equipotential bonding
Duct sections are normally not interconnected with electrical conductivity.
To create the necessary equipotential bonding, the connectors and fittings
have drill holes. Turning in the supplied connecting screws allows the cre-
ation of an electrically conductive connection between the duct sections
(see Fig. 69).
Note!
Turn the connecting screws in such a way that the screw head is pushed
firmly against the duct lid, creating an electrically conductive connection.
However, neither the connector nor the fitting may lift off of the duct end
pieces, but must enclose them tightly.

Creating equipotential bonding using connectors
Create a connection to the building's equipotential bonding system at one
point in the duct, e.g. using a cable lug on a fastening screw of a con-
nector or fitting (see Fig. 70).
