Functions of the shield contact
The shield contact:
● Is needed to fit cable shields (e.g., for analog modules).
● Interference currents on cable shields are diverted from the shield connection to ground
via the mounting rail. The shielding connection is not required at cable entry into the
switchboard.
Reference
Further information on wiring the inputs and outputs can be found in the manuals for the
I/O modules.
