Terminal block

Overview
All electric connections and also the signal connections of the field control unit are present on
the terminal block on the DIN rail in the field control unit. Also connect the cable coming from
the field module here. The cable connections on the device side of the field module are already
preassembled when delivered.
Note
Strain relief of the connecting cables
Make sure cables are routed without force so that the strain relief of the cable gland is not
overloaded.
If necessary, install an external strain relief.
