4.1.4.3.3 Grounding
Caution!
The functional ground (power supply pin 2 and ground connec-
tion) must be connected to the central grounding point (e.g. con-
trol cabinet or system) via the shortest possible path with the low-
est possible resistance and with the largest possible wire cross
section. This type of grounding is mandatory for proper function-
ality.
For example, a copper strip must be attached to the ground connection at a central grounding point of the control
cabinet or system in which the device is installed. The wire cross section should be as large as possible (at least
2.5 mm²).
