Remove the junction end-cap from the junction housing.
b.
Loosen each of the four cap screws (4 mm) inside the junction housing.
c.
Rotate the bracket so that the transmitter is oriented as desired.

3.4 Grounding the Transmitter
Improper grounding could cause measurement error.
To reduce the risk of measurement error:
•
Ground the transmitter to earth, or follow ground
network requirements for the facility.
•
For hazardous area installations in Europe, refer to
standard EN 60079-14 if national standards do not
apply.
