Shielding Concept
The measuring accuracy of the fault recorder can only be maintained if the voltage and current signals are
connected to the device using shielded lines (1).
Siemens recommends stopping the cable shield at a maximum of 10 cm before the device terminals (1) and
connecting the cable shields near the device with low impedance via the shield terminals (4) to ground poten-
tial (2).
