3.6.2 Connection to control section
The connection to the control section is made using the plug-in connection
terminals:
•
Terminals 1, 5, 7, 9: for the internal power supply,
•
Terminals 2, 3, 4, 6, 10: for digital and analog input signals,
•
Terminals 8, 11: for a digital or analog output signal,
•
Terminals 14, 15, 16, 17, 18: for dry relay outputs,
•
Terminals 12, 13: for the STO inputs.
The 13- and 5-pole control signal terminals can be plugged in.
In IP20 protection (FS2, FS3, FS8), the control signal terminals are mounted
on the front; in IP55 (FS4, …, FS7) and IP66 protection, they are mounted
under the enclosure cover.
3.6.2.1 Terminal capacities
The connection terminals’ layout depends on the frame size of the power
section. The cross-sections to be used in the connections and the tightening
torques for screws are listed in the following.
