Removing wires
Using the screwdriver, press the spring release of the terminal as far as it will go and pull out
the wire.
Note
When you press the spring release, you should not pull on the wire/cable at the same time.
This prevents you from damaging the terminal.
6.8 Connecting cable shields for I/O modules
Introduction
● You need the shield connector to contact cable shields (e.g. for analog modules). The
shield connector conducts interference currents on cable shields to ground via the
mounting rail. It is not necessary to contact the shield at where the cable enters the
cabinet.
● Attach the shield connector to the BaseUnit.
● The shield connector consists of a shield contact and a shield terminal.
● The shield connector is automatically connected to the functional ground (FG) of the
mounting rail after installation.
Requirements
● BaseUnit with a width of 15 mm
● The shield terminal is suitable for cables with max. ∅ 7 mm each.
