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 t he

MGate 4101-MB-PBS/4101I-MB-PBS

device’s termina l 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 pla ce. For wall

mounting,
install the wall mount kit (optional) first, and then screw
the device onto th e wall. The follo wing figure il lustrates
the two

mounting options:
