Hardware Installation Procedure

1. Connect the power adapter. Connect the 12-48 VDC power line or
DIN-rail power supply to the MGate 5114’s terminal block.

2. Use a serial cable to connect the MGate to the Modbus RTU/ASCII
or IEC 60870-5-101 device.

3. Use an Ethernet cable to connect the MGate to the Modbus TCP or
IEC 60870-5-104 device.

4. The MGate 5114 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:
