Secure the device to the panel with 4 screws. For dimension drawings see Section 4.23 Dimensions.
•
Connect the low-resistance operational and protective earth to the ground terminal of the device. The
crosssectional area of the ground wire must be equal to the cross-sectional area of any other control
conductor connected to the device. It must thus be at least 2.5 mm
2
betragen.
•
Alternatively, there is the possibility to connect the aforementioned earthing to the lateral earthing
surface with at least one M4 screw.
•
Connections according to the circuit diagram via screw terminals, connections for optical fibres and elec-
