Notice!
The designation and function of the SWIO depends on the connected device. Please observe
the following table!
Supply voltage
Attention!
For UL applications, use is only permitted in class 2 circuits in accordance with the NEC
(National Electric Code).
The fieldbus gateways are designed in accordance with safety class III for supply by PELV
(protective extra-low voltage with reliable disconnection).
Connecting functional earth FE
Notice!
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 connection.
Switching input/output
The MA 258
i
is equipped with the
SWIO_1 and SWIO_2
switching inputs/outputs. This is
located on the PWR IN M12 connector and on the PWR OUT M12 connector. The connec-
tion of the switching inputs/outputs from PWR IN to PWR OUT can be interrupted by means
of a jumper. In this case, only the switching input and output on PWR IN are active.
The function of the switching inputs and outputs is dependent on the connected Leuze
device. Detailed information on this topic can be found in the respective operating instruc-
tions.
