Connecting The Leuze Device; Connecting The Power Supply And The Bus Cable; Starting The Device - Leuze electronic MA 258i Operating Instructions Manual

3.3.1

Connecting the Leuze device

 To connect the Leuze device to the internal RS 232 device interface, open the housing
of the MA
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.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 258i, the device selection switch is queried and the gateway
automatically sets itself to the Leuze device.
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.

Connecting the power supply and the bus cable

 Ideally, use the ready-made cables listed in chapter 14.4.3 to connect the gateway to the
power supply via the PWR IN connection.
 The ready-made cables listed in chapter 14.5.4 are preferred for connecting the gateway
to the fieldbus via the HOST / BUS IN connection.
 If applicable, use the BUS OUT connection if you would like to construct a network with
linear topology.
