Hardware Installation Procedure
1.
Connect the power adapter. Connect the 12-48 VDC power line or
DIN-rail power supply to the MGate 5103’s terminal block.
2.
Use a serial cable to connect the MGate to the Modbus device.
3.
Use an Ethernet cable to connect the MGate to the PROFINET IO
controller.
4.
The MGate 5103 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-mounting kit (optional) first and then screw the device
onto the wall.
The following figure illustrates the two mounting options:
