Connect a solid low-ohmic protective and operational ground to the grounding terminal of the device.
The cross-section of the cable used must correspond to the maximum connected cross-section but must
be at least 2.5 mm
2
(Grounding area > M4, grounding area to be lacquer-free).
•
Connections are to be established via the screw terminals on the rear panel of the device in accordance
with the circuit diagram. The details on the connection technique for the communication modules at the
bottom of the device (port A and port B) in accordance with the SIPROTEC 4 System Description and the
