Fig. 5-2 Dimension drawing of single I/O module
The single I/O module has an equipotential bonding terminal. To conduct inter-
ference currents away, a low-resistance finely stranded bonding conductor to
the ground bus is required (see Subsection 2.1.3) with a cross-section of at
least 10 mm
2
. The connection must be as short as possible. When the PE and
interference conductors are in common, the PE conductor rules in EN
61800–5–1 must be followed.
