Commissioning and configuration
12.1
Measures to be performed prior to the initial commissioning
Before commissioning, familiarize yourself with the operation and configuration of the
MA 258
i
.
Before connecting the supply voltage
,
recheck all connections and ensure that they
have been properly made.
The Leuze device must be connected to the internal RS 232 device interface.
Connecting the Leuze device
Open the housing of the MA 258
i
and lead the corresponding device cable (see chapter
14.6) through the middle threaded opening.
Connect the cable to the internal device interface (X30, X31 or X32,
see chapter 7.5.1
Use rotary switch S4 (see chapter 8.2.5) to select the connected device.
Now screw the PG cable gland into the threaded opening to provide strain relief and
ensure protection class IP 65.
Finally, close the housing of the MA 258
i
.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 258
i
, the device selection switch is queried and the gateway auto-
matically sets itself to the Leuze device.

Check the applied voltage. It must be in the range b18V … 30VDC.
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.
