Commissioning and configuration
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 204i, the device selection switch and the address settings are
queried and the gateway automatically sets itself to the Leuze device.

Check the applied voltage. It must be in the range between +18V ... 30 V DC.
Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connec-
tion.
On delivery, the SWIO 1/2 are connected in parallel on PWR IN/OUT. This connection can
be separated with a jumper.
