of the DIP switch correspond to your requirements.
2.1.4 Connecting the terminal blocks for supply voltage
and signal contact
The supply voltage and the signal contact are connected via a 6-pin terminal
block with a snap lock.
Caution!
Note the safety instructions
only connect a supply voltage that corresponds to the type plate of
your device. Make sure that the contact load capability of the signal
contact is not exceeded
Supply voltage

Redundant power supplies can be used. Both inputs are uncoupled.
There is no distributed load. With redundant supply, the power supply unit
supplies the device only with the higher output voltage. The supply
voltage is electrically isolated from the housing.
You can choose between DC or AC voltage when connecting the supply
voltage. You use the +24V and 0V pins to connect the AC voltage
