230 VAC supply lines and data lines must be wired separately with a minimum
distance of 10 cm between them. We recommend leaving space between the
supply and data lines inside the control cabinet as well.
Digital data/bus lines and analogue data/sensor lines should be wired
separately.
We recommend using shielded cables for analogue data lines.
The shielding should be earthed at the entry IN or exit OUT point of the con-
trol cabinet. The shielding should be as short as possible and have as large a
cross-section as possible. The central earthing point should be > 10 mm² and
connected to the earthing cable using the shortest possible route.
The shielding is normally only connected to the control cabinet on one side,
the shielding resistance.
Inductive loads installed in the same control cabinet, e.g. protective coils, must
be equipped with suitable snubbers (RC elements).
