V Mount the terminal block for the supply voltage and the signal contact on
the front of the device. Make sure that the snap lock snaps into place.
By connecting the supply voltage at the terminal block, you start the
operation of the device.
2.1.9

Assembling the device on the ISO/DIN rail, grounding

V You mount the device on a 35 mm hat rail according to DIN EN 60175.
V Attach the upper snap-in guide of the device into the hat rail and press it
down against the DIN rail until it snaps into place.
Note: The shielding ground of the connectable twisted pair lines is connected
to the lower panel as a conductor.
