Hardware Installation Procedure
STEP 1:
Connect the power adapter. Connect the 12-48 VDC
power line with the
MGate 4101-MB-PBS/4101I-MB-
PBS
series’ terminal block, or connect the
DIN rail power
supply with the
MGate 4101-MB-PBS/4101I-MB-PBS
device’s terminal block.
STEP 2
:
Use a
PROFIBUS cable to connect the unit to a
PROFIBUS
PLC
or other PROFIBUS master.
STEP 3
:
Connect your device to the unit’s serial port.
STEP 4:
Attach the device to a DIN rail or the wall. The MGate
4101
-MB-PBS/4101I-MB-PBS series is designed to be
attached to a DIN rail or mounted on a wall. For DIN rail
mounting, push down the spring and properly attach it to
the
DIN rail until it snaps into place. For wall
mounting,
install the wall mount kit (optional) first, and then screw
the device onto the wall. The following figure illustrates
the two
mounting options:
