Connectors of the digital inputs of the SCALANCE X414-3E
Polarity reversal protection X1, X2
The two 5-pin male connectors (X1, X2) of the digital inputs 1 through 8 have no polarity
reversal protection. If the connectors are accidentally swapped over, this does not cause
damage or destroy circuits. In display modes A and C or B and D, incorrect inputs are
displayed during the time the connectors are swapped over.
WARNING
The input voltage must not exceed + 30 V and must not fall below – 30 V, otherwise the DI
module will be destroyed.

on the DI module.
