Outputs 1 and 2 can be used for both mains power and low voltage (e.g. 24V).
If one of the two outputs is used for the mains voltage, the other output must
not
be used
for low voltage.
4.2.2
Control contacts
Decive enable
Note:
Input 3 must not be connected with the mains voltage or with low voltage. It may
only be connected with a floating switching element.
