Connecting the PE conductor

A connected PE conductor conducts dangerous electrical charges to the metal enclosure.
The current flowing through the PE conductor in such a case trips the line-side fusing device
that disconnects the device from the power supply.
Moreover, the PE conductor improves the conduction of interference that is transmitted via
external power supply cables, signal cables, or cables to peripheral devices. The connection
for the PE conductor is marked with the following symbol:
