● Self-generating interference leakage from the terminal module to the mounting rail by
means of spring contacts
● Prewiring of the terminal module is possible
Note
The spring contact to the mounting rail is used to connect the cable shield of the PROFIBUS
DP cable with the equipotential bonding system during operation.
